Jack Critchley Posted November 12, 2011 Share Posted November 12, 2011 I am wondering how much down and sidethrust to incorporate in my latest rebuild. It's a Yellow Aircraft Inc. Giles G-300, 60" span ,electric conversion, A.U.W approx 7to8 lbs. There seems to be a lot of conflicting advice around on this topic, some ( Alex Whittaker) saying none, others saying plenty!!!

ken anderson. Posted November 12, 2011 Share Posted November 12, 2011 hello jack-unless the instructions stipulate it for the model......put it together and fly it......unless its going in for pure aerobatic comps - i wouldn't be too concerned.... ken anderson ne...1 thrustline dept....

Biggles' Elder Brother - Moderator Posted November 12, 2011 Share Posted November 12, 2011 I agree with Ken on this. Build the model as per spec then fly it. No model with slightly incorrect side or down thrust is going to be unflyable. It might not track exactly vertical and it may have a tendency to zoom when you suddenly open the throttle in level flight - but these sorts of things can be ironed out later. For now, just do as the designer intended and see how it goes.

Jack Critchley Posted November 12, 2011 Author Share Posted November 12, 2011 Many thanks for those replies. It's an old ,much crashed artf, which I bought as a "project"so don't have any Mnfrs advice. It does not seem as if any angles were built in. Will stop worrying and take your advice. Great forum!!! Best Regards, Jack. Quote Link to comment Share on other sites More sharing options...
Ultymate Posted November 12, 2011 Share Posted November 12, 2011 Most aerobats on average run 2 1/2 to 3 degrees right thrust and zero up or down thrust, this should give you a good starting point, then fly and fine tune. Quote Link to comment Share on other sites More sharing options...
