Yes the wings are coming out better and better thanks to everyone's suggestions and advice
This one is just for some fun, not really for going super fast. Have built it solid, but not heavy.
The RT28 topped out at 121mph and the RT30 still holds the 30" WR at 171mph in 30-35mph winds.
If I can some progress, having problems atm, I will have some nice RT30 molds
Test chucked the RT42 down at the park just now to get it CGed. I should have gone out to the middle as third throw was amongst some small saplings and I put it perfectly into a waratah post. Embedded itself on the LE. Fixing now
