No need to apologise. Quality bears repetition.

Two servo or Y lead for your ailerons ?
Wookman replied to Rocker's topic in All Things Model Flying
Two servos and two channels will also offer the chance to adjust the aileron differential. -
You have such massive and rewarding journey ahead of you.

Nice job John. A couple of, hopefully constructive, oservations. Silver is a notoriously difficult colour to see in the air. More orange trim on the wing tip tops and the fuselage will help. When you do fly it I imagine that trimming the elevator is going to be interesting with the two bends in the bowden cable and the raked back horn position that will give much more up than down elevator movement. You could cure the unequal elevator movement, if it is an issue, by raking the servo arm aft and re centering the elevator. If the backlash in the bowden cable proves to be excessive, I would suggest a mini or micro servo in the top of the fin with a short push rod to the elevator. Club finder on the BMFA website is your friend. You may find that your nearest slope flying club is at Whitesheet in Wiltshire. There is certainly plenty of expertise at the club to help. -
Sig Samurai Pitcheron Build
Wookman replied to Edgeflyer's topic in Slope Soaring and Dynamic Soaring
Minor issue with pitcherons is they can be difficult to slow down for landings. Nice looking plane, have fun. -
Custom duties on a used model from outside the UK?

Or taking? -
Custom duties on a used model from outside the UK?
Wookman replied to Jonathan M's topic in All Things Model Flying
If it is used/second hand are customs and import duties applicable? -
From memory the Luna has a straight trailing edge and a taper on the leading edge. If so 40% of root chord will be a good starting point for CG. Eye ball the AMT parallel with the wing get your mate to launch it and be ready on the elevator stick/trim. A bit of aileron differential will be nessecary with the down going aileron moving somewhere between half to two thirds that of the upgoing aileron. 15mm up 8mm to 10mm down. You might want to put something on the BARCS forum.

5s 2000mah AA Sanyo Eneloop LSD Nimh. Simple and reliable. Make sure the servos are rated for 6v. If not use a 4s as above.

Do we overpower our models these days?
Wookman replied to Robin Colbourne's topic in All Things Model Flying
Absolutely modern models are over powered. Throttles are the answer. Back in the day when the biggest motor you see at the patch was a Webra 61 I did see one in an MR Hurricane. No flaps or retracts but it did fly well. The tooth pick on the front looked a bit odd though. The prototype PMP Kerfuffle flew well on a MDS 38. Mine had a Irvine 53 with an inch cut off the front of the fuselage sides. Good fun. -
If you have Uni Firmware on the rx will that not self tune during the bind process to the Tx?
