I just finished and test flew mine.

I'm using a G-38 with an APC 18-8. It flies nicely with this combo. Not unlimited vertical but plenty of power. I'm a pretty light builder and had to add 1/2lb of lead to the TAIL to balance this heavy motor. I think a G-62 would be too much and may not fit in the cowling.

Have fun.
