By the way, has everyone just used covering as the hinges for the ailerons? And what size servos? Anyone brought cheap from hobbyking?

Yes, quite a few of us have used the covering for hinges. I covered the bottom of the wing and the aileron first. Then taped the aileron in place using diamond tape on the bottom. Then covered the top of the wing including aileron in one piece.

I used New Power XLD-17MB Digital Servos which I got from Phoenix Model Products. Cost £10.95 each.

Dave, follow as per Mike BUT when covering top of wing lay it down with aileron in the flopped down position, about 45degrees. If you don't the aileron will unable to flex down.

Yep one of the best ways of hinging surfaces. I have used this method using 3 layers of film on a 42% cap 232,it also seals the gap on the surface

I really pushed the boat out when purchasing my servos. - They have survived one flight so far but only time will tell - and they are available at a whorehouse (sorry warehouse) near you !! www.hobbyking.com/hobbyking/store/__2476...2_2kg_0_10s_12g.html


My flappy bits are fixed with strips of transparent solartex top / bottom prior to covering. like flying pete , I have also used this method on Petrol powered a/c as recommended on ALL Glens early aerobats. When i decked my big extra during a precision approach by hitting a fence post - the control surfaces remained intacked . B_ _ _ _ _ _ d !

I hope the fence post came to no harm? :whistle: :whistle:

Don't want to be too critical Dave but I'm not sure you will see you model in those colours on a dull day. Watching mikes fly on sat it covers the ground pretty fast and deciding which way up it is quite a challenge. Make the fins a bright colour to give yourself a chance !!

To be honest, Simon, I cannot see the colour on mine when it's beyond the field. So I don't think Dave's choice of colour will be an issue.

BTW, Dave, when are you back? We'll try not to crash so we can arrange a date for all 11 to be at Cashmoor on the same day.

4.75 x 4.75 props from HK

I borrowed one of these from PhilF on Saturday and the performance was good, so I've just ordered sixteen 4.75x4.75 props from HK. The unit price is $1.23 for two and with shipping they will work out at about 60p each compared to genuine APC props at about £2 each. I'm happy to sell them on to anyone who needs one.

Unfortunately, they don't do the 4.7x4.2 "formation" prop but these are available in genuine APC nylon from Robotbirds at £1.85 plus shipping. Perhaps someone else will order a bunch of these for the group?

Mike

Please put a couple of those props by for me Mike.
Thanks,
David
