I would like to reduce the airspeed of my trainer a bit and am not sure of the best approach. Should I modify the wing, lighten the load or what? I am trying to get it down a bit so my son will feel more comfortable giving it a try. Sure enough though, he'll catch on and want to fly the wings off the thing in high gear shortly after. Anyway, any ideas to simply slow it's minimum airspeed and maintain flight?

Thanks.
