  • Activities

    Wimborne Model Aero Club holds many activities and events through out the year at our Cashmoor flying site and also our monthly Club Nights.  These events and activities are notified by Newsletter to club members or are posted on the Discussion Board in the relevant forums.

    Events and competitions at Cashmoor throughout the Spring Summer seasons cover all types of fixed wing flight.

    Social Club Events.  We also hold events not necessarily connected to RC flying.  Guest speakers from specialist areas of the aircraft industry, restaurant nights, Skittles evenings and RC flight simulator evenings.  the latter normally on Club nights.

    Charitable Events.  Several times a year we support local charities and school fairs free of charge as an aid to the local Community by putting on Static Displays of models, construction techniques and a RC Flight Simulator.  The Flight Sim gives the event's visitors the chance to fly an RC model on a large screen TV, the latter very popular with children and adults alike.  This also helps promote RC flight in general as a pastime and sport and to encourage the younger generation to get involved thus enabling the hobby to continue into the future.

     Scale Model

    WE will probably never be able to fly the real thing but scale aero models will get us somewhere close with satisfaction.  Picture on the right looks like the real thing or is it?  Or it is a scaled down version of the real thing.  Scale or true scale?  True scale is very intensive modelling so generally for RC scale models "stand-off" will suffice. Stand-off is from about 5 meters but we won't hold you to it! 

    There are lot's of ARF scale models to chose from, some better than others, thanks in some part to the Chinese although the designing may be by top aero modellers.  Picture right is a DHC Twin Otter (STOL) as used by the US Army Parachute Team.

    With scale models you can be whatever you want - favourites are Spitfire, Mustang, P40 pilot.  Once these models are in the air, some having more presence than others, they appear to be the real thing.  They will have similarflying characteristics to their full size counterparts but usually the designer will make some changes to make the aircraft easier or more stable to fly.

    This may entail changing wing washout or modifying the wing profile.  Cowlings may be extended to get balance and landing gear may not always be correct but we don't always quibble over it.

    Although flight is likely to be very similar to the full size, take-offs and landings will need a lot more care with these models.  Roll outs can be greatly assisted by using the flaps but landing does need extra care.  Scale models don't like hard landings especially those with retractable wheel gear.  So, a good approach, glide path and gentle touchdown is recommended.

     Open Scale Days are held at least once a year.  Below are some of our Members Scale models - see more in the Photo Gallery

     Gliding - Soaring

    Gliding generally deemed as silent flight using just the wind and/or thermals to keep the craft in the sky.  A truly fascinating side to RC flight with many people just taking up this type of flying only.

    Depending on your geographical position or flying site the use of electrically assisted climb up is becoming very popular, especially now with the advent of powerful, light brushless inrunner, outrunner motors, although some classes still specify standard brushed motors.

    Without power asssitance to climb up the alternatives are off a windy slope (soaring), bungee launch and the aero to(towline) by a large, powerful aircraft.  The glider once up to height releases itself from the tow hook and seeks thermals to stay aloft.

    Wimborne Model Flying club has lot's of experienced pilots to this hobby with years of flight without engines.  A slightly different skill required here from powered flight - no power out of a problem - you have to fly it out!  Maybe that's the fun of it!

    Too windy for general power flying?  Not a problem for WMAC members because it's off to the hills of Dorset for some fun.  Because this relys on the right weather, being always changeable the Forum updates with latest information.

    All year round we fly on the slopes when the weather permits or is suitable.  However, even in high Summer the conditions can change suddenly therefore always come prepared with waterproof coat or jacket, hat and a waterproof bag to protect your transmitter.  Drinks too, hot or cold to stave off dehydration.

    All year round sport from dawn to dusk.  All we ask for is a favourable wind of over 13 mph.

    Join the Club and join us on the slopes.

    Aerobatics

    Aerobatics your preference?  Love to watch?  Do you wish to get involved in high level aerobatic competitions like IMAC?  Extreme 3D? Many of our members are into aerobatic flying.  From small foamie models to giant scale gasoline powered scale models.  Starting off with a 60 size aerobatic model is the normal jumping in point.

    Sixty size are not too expensive and can be glow or electric powered.  Practising manouevres will always be a little terrifying at first and there will be heart-stopping moments and possible crashes.  You have to expect it at some time of other!

    Inverted flight, stall turns, inside and outside loops (bunts), snap rolls, flat spins and much more are very eyecatching and great fun to watch and achieve.  The aerobatic models are designed to withstand high G forces and with wings generally centrally mounted and large control surfaces, the manouevres are easier to achieve and helped with power to weight ratios much more than standard sport models.

    Many of our members own these aerobatic models, some are scale versions of the full size aircraft and powered by powerful electric brushless motors, large glow motors and top of the shop two stroke petrol single and twin cylinder power too.  Petrol power starts from a meagre 20cc, 50cc up to 150cc and beyond.

    Members with large scale gas powered models enter into competitions such as the ever increasing popular IMAC competitions.  The latter are precise aerobatic flght patterns but also include freestyle flying which is done to music if you so wish.  There are multiple judges in IMAC awarding or deducting points on all manouevres after take-off.

    Or for weekend sport flyers you can gain much pleasure from just throwing it around the sky for fun and adrenalin rush!

     



     

    Turbine

     For many people the turbine powered jet needs a deep pocket and also the experience of many hours of RC flying.  Although airframes have come down somewhat in price and vary between traditional balsa - ply construction and the more popular composite construction, the latter strong but light.

    A few of our members have turbine powered jets and attract a lot of attention when they are present up at Cashmoor.  The smell of kerosene or parafin mixed with turbo oil) and the whine of a turbine is something to enjoy.

    Turbine power requires a lot of avionics on board to enable the model to fly.  Safety devices to cut off the highly imflammable fuel or an onboard fire.  Pumps and regulators all add to the expense and that is not including the fuel which is burnt at an alarming rate.  A gallon doesn't last long but that 8 - 10 minute flight is something to behold and enjoy.  An adrenalin rush to appreciate! 

    EDF

    Meanwhile, coming back to something more afforable for the masses is the EDF jet.  All shapes and sizes and able to be flown by less experienced pilots and tend to survive some crashes some of the time.  More likely to be able to repair this type of model.  Afforable they are too!   Pictured right is an EDF model of the Breitling Display Team

    Composite fibre scale models are very light and although they started life at the Turbine end of the market as EDF fans became more efficient and powerful they were also became popular.  Power to weight ratio was much improved and therefore they would be able fly like a jet should, including vertical climbs.

    Made from EPP or EPO foam (expanded plastic) and powered by the screaming EDF power plant. EDF = Electric Ducted Fan).  The small but powerful motors in these units will be rotating the fan at speeds of 20,000rpm up to 48,000 rpm and drawing high amounts of current from the battery pack, typically LiPo (Lithium Polymer).

    These lightweight EDF models will come in ready to fly (PNP), almost ready to fly(ARF) versions at very reasonable prices and therefore virtually all can be Top Gun pilots. Average prices from £40 - £185 depending on size and the amount of build already done.

  • Airworld Hawk T1 1/4 scale

    hawk t1

    A New Hawk T1 arrives at Cashmoor for a maiden flight on Saturday the 23rd February.  Dave Bright moves up from his slightly smaller version we have seen numerous times at the field to his 1/4 scale version by Airworld.

    Jetsmunt M200XBL (45lbs thrust) turbine.  2.34m span. 2.81m length. Powerbox Mercury, 12 JR Servos, Bound to his JR 12X radio. The maiden day was not an ideal day with a small amount of hazy sunshine but mainly grey skies and a light southerly crosswind

     More still images can be seen here in Dave's Gallery.

     

     

  • Bae Hawk - Maiden

    Bae Hawk

    Edited down version of Dave Bright's first flight of his Bae Hawk on the 26 November 2016. It was extremely cold and overcast skies.  Not the best of days for first flights or maidens.  Earlier Jon Tappin took the sticks for it's maiden flight whilst the few members who braved out the chill watched, some with camera ready.

     

  • BVM BobCat

    bvm bobcat

    New member Phil Mackie of Wimborne MAC flew his BVM BobCat at our Cashmoor field for the first time on the 18th January 2020.  Although quite cold there was a great blue sky with high light cloud to fly across. He had an excellent flight and made an excellent landing after a trial landing approach.

    Turbine Power is a JetCat 160. Goes like a scalded cat!  At cruise power the engine is very quiet and the plane flies very stable.

     

  • BVM Electra

    BVM electra

    From the BVM stables of turbine jets comes an electric composite fast jet in kit form or ARF.  On the 30th August on an excellent day weatherwise, John brought up the field his new BVM electra fast jet.  We were surprised as John has become a bit of turbine fanatic in the last few years. John handed over the maiden flight to Jon who gave it a test flight.  Fairly quiet as EDF's go but open up the throttle and it moves very quick.  Gives camera men a difficult time keeping it in focus and view.

     

  • Carf Ultra Flash

    Ultra Flash

    A very sleek low profile fast jet, the Carf Ultra Flash.  This jet covers a lot of sky very quickly and makes for impressive viewing.  Here on the 30th August 2018 Jon runs up the Ultra Flash for two flights over the day.  During a break he took on the sticks of another jet for it's first flight, a F15.  The Ultra flash is acomposite airframe, air retracts and powered by a Jet Munts 140 turbine.

     

  • EDF & Jet Day + Open Scale Fly-In

    military jet

    Wimborne MAC's annual EDF & Jet plus the previously cancelled Opn Scale Day.  Dry this time round although the wind was challenging at around 14mph but at least was blowing down the strip from the west.  Lot's of different models to view and many pilots opted to fly.  Lot's of banter and  laughs thoughout the day.

    Thanks go to David as Master of Ceremonies, Stuart for presenting the awards, Colin for assisting with pilot logging and issuing voting slips after the pilots first flight. Only pliots who opted to fly were able to vote on the various categories covering scale, flying and best overall.

     

  • EDF and Jet Day

    Hunter

    WimborneMAC’s annual EDF & Jet day took place on Sunday 2nd October. It promised to be an excellent day with fine weather and light winds. I arrived at 0820 hrs to put up the safety fence, I had already mown the airstrip in advance on the previous Wednesday. David Tappin, event director arrived a few minutes later and got tables and equipment ready.

    By 9 am members were starting to arrive and getting set up with their models. Those without any form of jet would also get some flying time in although jets and EDF’s get priority. Surprisingly for the the first time ever I can recall, the turbines five of which flew many times plus 3 others which only didn't feature in the following competition results because they didn't fly, outnumbered the EDFs

     

  • Jet Day 2017

    L39 Albatros

    The annual Jet Day earlier was postponed due to poor weather conditions and was given the new date of September 23rd.  Generally a bright blue sky but with a "breezy" crosswind howling in from the SSW.  However, this time we were not to be beaten and all pilots got at least two flights in.  Due to crosswind though some members decided to stay away so numbers were down a little.  We had a few edf foamies of which only five flew, the classic F86 of Dave R burned out it's speed controller again, but we had the sight of two Me 163 Komets flying in formation - sort of!

    Jets actually flown were two turbine sport jet models plus a Bae Hawk, De Havilland Venom, F9F Panther and Jiri's new L39 Albatros.

     

  • PC21 50e Vario Prop

    pc21

    This is an assembly and customisation article of this popular and sleek military trainer from Sebart.  The model comes in three variations of colours.  The model featured is the third generation, version 3 which has all metal retracts.  The earlier versions were plastic and caused many pilots grief, modifications were mad eon theMKII but many swapped out their retracts for E-flite trike sets with anti-jam feature adding around £120 to the cost of the model. Sebart's third genration has all metal retractsand uses a sequencer circuit to operate the gear. On the sequencer there are two spare pins which  can be used for other items that need to be switched when the gear is triggered. Landing lights?

     However, in this article I am upping the scale looks with a super looking prop just like it's full size counterpart and some customisation.  Some info on the real beast first.

     

  • Scale Day 2 of 2016

    P47 SNAFU

    Scale Day 2 was blessed with a bright sunny September Sunday after the washout of previous Saturday. Quite a reasonable turnout although more pilots were expected. Numbers may have been down due to holidays. We had members from Salisbury MFC and Wincanton too. Unfortunately, due to a lack of a tug after an issue on Slim Gregory Day we did not have any scale glider models arrive on site. However, a number of members just came to watch the flying and picnic including friendly banter. There were also a couple of visitors and families who seeing the road signs came up to watch too.

    With quite a wide range of models flying there was eyecandy for everyone. From WW1 biplanes, British and German to WWII fighters, the venerable Spitfire and the P47 Jug (on it's maiden flight) to Korean and Cold War jets.
