I told my friend about RCU and the great advice you provide and he would like me to ask this for him. My friend’s two choices for a second plane are as follows below. Please help him decide. He will check back with me sometime in next week or two. He has flown for two years, taken a year or so off, but wants to get back into it. He will take one of my planes up to get the feel of flying again while he is building one of these two kits. He will then help train me.

So here’s his first choice:
Sig Four-Star 60 Kit .60-.75,71"

if it can be converted to have the main landing gears on the wing.

That is his first choice as he wants a tailwheel. He wants the landing gear on the wings, so if that one can not be converted this is his second choice:
Great Planes Super Sportster 60 Kit .45-.61

And what would be the best engine choice for these two?
