Ranger 1600 - 405 Wing

ranger 1600 original

The Ranger 1600 from Hobbyking is another plane from the milk bottle stables, ie; plastic fuselage and very similar stabiliser and tail fin to the Phoenix glider range.  The big difference though is the plug in wings so no screw driver required.  The Ranger is designed for much easier hand launching and virtually a mid-wing type plane.  This model is very similar to the Bixler series except it now has a virtually indestructable fuselage!  The front nose has a flat area with a small aperture for a camera if using it as FPV.  It is quite capable of powered flight or used for slope soaring, your choice.  The plane comes with  pre-wired servo connections, 30 amp ESC and a unbranded 2212 1400Kv brushless outrunner and designed to run on 3 cell Lipos in the 1600 to 2200 maH range. These batteries will balance the model perfectly.

Phase 5 by Chris Foss

Phase 5 Maiden Flight

After many years of procrastinating I'm finally building a Phase 5. Designed in 1978 this model is often considered to be Chris Foss's (CF) best slope model. It was never available as a kit so the only way to get one is to build it yourself. CF is still selling the plans if you fancy one.

The Phase 5 plan calls for a built up wing but I'm deviating from the plan and making one from foam with a balsa skin. A snow day today meant I could make a start. CF does not specify what sections are used for the root or the tip so a bit of guesswork and internet trawling resulted in the semi-symmetrical E374 for the root, modified a little to make it thinner. The tip is fully symmetrical and is between NACA 0010 and 0011. It's actually 10.67% thick so maybe it's NACA 0010.67?

The Flying Dolphin

Once upon a time in a galaxy far, far away, well planet earth any way, back at the Nationals of distant past. Jon Tappin and I used to compete against a man called John Dodd in F3A.  We were absolutely amazed that in the evening he brought out a flying dolphin which was free flight. This little thing was so stable, more stable than me that is for certain; it always stayed in our minds.

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.
