RE: GUILLOWS BUILDERS?
Yup. Check the incidence of the horizontal stab, the two wings, and the motor. I used an IPS size geared motor with a 9x4.7 gws prop, and a 2s lipo. in my zero. She's not finished yet, but she should be a decent flier with this setup. Just remember, build meticulous, and don't be afraid to substitute better wood for parts. Like the stringers, formers, ect. The guillows wood is horrible, very heavy, lot of weight can be saved this way. Let us know how it turns out, these projects can be challenging, but also very rewarding.
