I started the fuselage today (I glued two parts together and pinned them to the board). I need to cap strip the lower wing but that's cosmetic so I'll do that before covering. Most BUSA QS kits are designed around a G-26 for the power and weight. I did a little research and found out the NGH 38cc gas four stroke I'm going to use on this plane weighs a couple of ounces more than a G-26 but costs less (based on Horizon Hobby prices). I'm not endorsing anything and you can use anything you want but I do love that four stroke sound!
