Default RE: Rolling issues with Comp ARF Impact

Peter,
I found that it only took one (1) degree more on the ailerons to get it close. I did fid that the rudder needed to be more sensitive around neutral. We added some negative rudder expo, (about - 5% in JR speak, + 5% in Futaba speak). Then rolls could be smoothedoiut all the way through the roll.

To take the rudder and elevator out of the equation, here is a test that you might try. Do some consecutive 1/2 roll-pause-1/2 roll exercises on long up and down lines to see if you get heading changes with aileron only.

Regards,

Eric.

I am trying to get my IMPACT dialled-in to my liking but I cannot seem to get it to roll as well as I like.

The rolls just don't seem to be as axial as I expected so I am taking a closer look at my linkage setup. I have tried different amounts of differential (yes, I have negative - more down than up) but it hasn't helped.


This is my first top hinged model with servos mounted on their side. I am not satisfied with my geometry with this configuration because of the length of arms involved. Can anyone give me some advice on the best approach to setup the geometry correctly. The angles look all wrong which I think is part of the problem. Servos are probably moving at different rates to each other throughout the entire travel range.


Thanks


Peter
