Everyone, what length servo arms do I need with this bird? I looked over the manual but for some reason cant find any lengths.
i am not at home right now, so cannot access the plans or manual, but I think the control throws are specified. So, you want to use as much servo throw as possible, so set up your TX to do that (usually means increasing things a bit from the default settings). You dont want the servos hitting any throw limits, either electronic or mechanical, and you want a bit of margin for trim throw.
Then, use the farthest out hole on the control surface horn that you can reasonably use, and finally, pick the hole in the servo arm that gives you the suggested throw.
