Yeah I thought about the Top-Flite but I wanted a bigger one. The Hostetler design is 125" span. I will be using a 70cc twin gasser. I don't think you have to worry about tip stalls with this plane. The gull wing design should help eliminate that. The wings are a lot of work as I am finding out.
If you go with the Top-Flite kit you will need to beef up the landing gear mounts, this seems to be a weak point with the kit.
Later!!
