Thoughts on a scale Sopwith Camel

STF said "Would adding some incidence or airfoil to the tail to add lift help relieve the rearward CoG?"
The problem there would be serious changes in angle of attack with speed, I know the Flee Bighters do it but those aircraft tend to fly at a constant speed. The last thing you want is for the nose to head south when you open the throttle!
Crash, there are going to be all manner of problems with this aircraft, I think increasing the rudder area by 50% would probably look just as naff as the long cowl. Mixes might be the order of the day to give lots of rudder with aileron.
Anyone know of a decent linear servo for the ailerons? A quick look shows some 1.7gm ones, but I hardly think they'll have sufficient urge. And the ones we use for Solar panel actuation are a bit large!

My kit has now been in and out of the Utrecht parcel centre 4 times, I hope it gets to the UK before the 1st January or I may have to pay Customs on it as well!

Linear servos - the only ones I've seen recently are intended for sail winches on r/c yachts and they might be a bit slow for ailerons!
Futaba made some nice ones a long long time ago, in the days of nicads, really tightly packed discrete components, five wire servos, and that lovely soft pink plastic case that bent under load! (I think I've still got one lurking in the junk-box!)

5 wire servos, expand please?

Nicad battery - four cells - centre-tapped - fed the rx
2.4 volts either way on the servo.
Otherwise the servo worked the same way as the modern ones, motor turns the gears that moves the output and the positioning pot, just a bit slower than modern gear - about half a second end to end!
-
I think it was voltage-matching, rather than digital matching, for zero, though. I never really bothered finding out!
-
If I've still got one of those ancient servos, do you want it to play with?

Yes please Eric, but it'll have to wait a while. You'll have to wait a bit for the reason why.

Tony - I'll have a rummage in the junk-box in the attic, when I get a round tuit, see if it's still there.

This is on hold at the moment, I have the kit, it's in the workshop gathering dust at the moment, and in any event Mary has said "Tiger Moth first!!!"
