Anyone know? I will probably quit worrying about this once my new delta is in
the air .
Thanks

If you are concerned, then set up the aileron function with strong exponential response to stick position. That way where will be ample response if needed during test flights yet the ailerons will be relatively insensitive around neutral. Test flights will reveal what you think the proper aileron sensitivity should be and the control response can be changed accordingly. As test flights progress, the exponential and control throws can be changed to suit your flying style.

It will be just because the delta style has a very short span for the amount of area (low aspect ratio) and the controls often tend to be made larger than you really need. But if you follow Ollie's suggestion it'll be fine. You'll also notice that the controls respond faster as the model speeds up. If it is twitchy at first then just keep the speed down until you get a feel for it.

Many folks I've seen and trained seem to use the sticks on the TX like a switch and blip the stick for supposedly small inputs. If you are one of these learn to just move the sticks with a whisp of pressure and WAIT for the model to slowly respond. It'll go a long way to making the model seem a lot more tame.

The answer to your question is "YES". Deltas tend to be quite sensitive compared to more normal aircraft. As Steve and Ollie say, the high expo will be of great help.

Deltas often have large aree compared with the span. That means that they don't take a lot of torque to roll very fast. They also tend to be on high speed models. So they don't take a lot of aileron to generate the torque :)

The results are as described above :D

Also try for a nice straight and level toss when getting airborne. Once my delta is on step, I've found it very stable and compliant, but over-correcting before it reaches step can be eventful.

If you have dual rates, you can use them (as well as expo) for the initial flight, though I suspect you'll shortly move to full rates at all times.
