J3 Cub - Flying technique
 

How to fly a Cub (Hanagar 9 1/5 scale full-wing) in this case. I know,,, use the rudder!!! and I do. :D

But the question is: is there some other techniques/set-ups that might improve the tracking in a turn. Does anyone raise up both ailerons, say 2-3mm? to improve washout?
Does anyone limit aileron travel, say more up than down so there is a spoiler effect on once side?

Sometimes I have to add opposite aileron to help hold the nose up in a turn. I'm looking for ideas to improve J3 Cub flying.
Thanks

Differential ailerons help with the adverse yaw. More up than down about 2 to 1. Mixing in the rudder to ailerons helps if you dont want to do it manually. I find that you have to lead with the rudder just a spot before you move the ailerons. It sounds like it is flying like the real thing though.

Differential ailerons and using rudder to make coordinated turns is all that it takes.
Having to add opposite aileron during turns is not uncommon for aircraft with high aspect ratio wings such as Cubs and gliders.

I wouldn't do anything to the mechanical setup of the model to "improve" the flying. Rather, I'd just take whatever odd flight characteristics you're noticing as a challenge to improve my stick control. When I was flying my Kyosho Cub I found that I would often be using cross control (rudder and opposite aileron) to get a nice looking turn. I also found I could fly almost as well with just rudder, elevator, and throttle.

I miss it.

The quarter scale cubs need a lot of opposite aileron in a steep bank to hold the bank angle steady. It is not something I think about consciously, just put the stics wherever you need to to hold the desired attitude....

Thanks for the replys! I guess the Cub flies like a Cub. Tell me, does a large long wing model such as the Sig Rascal 110, or Pacific Models Monocoupe (96 inch span) also fly the same, ie. requiring opposite aileron in a turn-depending upon the wind, etc.????
Thanks.

In a turn, the outer wingtip is following a larger arc than the inner wingtip, and thus is traveling faster. This creates more lift on the outboard wing and less on the inboard - this is without considering the effect of ailerons. So there is an aerodynamic force wanting to roll the aircraft towards the center of the turn, however, there may be other designed features which will affect this tendency - dihedral, washout, roll stability, airfoils, center of gravity, etc etc etc.

I haven't flown either of the aircraft you mention, however I have flown other long span aircraft, and so far, the Cub is the only one I have found with this tendency.......
