RE: Mojo build
Get the removable wing kit for sure!! It adds about 6oz of weight, but I've heard it's worth it. I have one of these, but have not started construction yet. I will do a build thread here when I start on it.
If you have ordered the kit, but have not got the removable wing kit yet, don't freak out. Call Paul at SwanyHouse and tell him you need the removable wing kit. As long as you have NOT begun construction of your kit, it's easy to add the removable wing. Once you start building, forget the removable wing. No longer an option.
Most guys power it with a Saito 100.
