My 9 year old wants to build her own plane, so we started on a SPAD trainer today. I am building it sort of per the BUHOR 25 plan, but enlarging it a bit. I am also adding a coro fuselage to hide/protect the radio gear and fuel tank, and to raise the wing up a little higher for better stability. Make sense?

So far we have the coro fuse, aluminum channel, engine mount, and wing pretty much fabricated. Right now, the wing span is 72", but the spar is shorter, so I'll probably trim the wing by 6-8". I'll see how stiff it is after it's all done and mounted. The wing is 2mm and the fuse & ailerons are 4mm. The tail will be built per the BUHOR 25 plan using 4mm.

I'm thinking that we will power it by a .32 BB engine, maybe a Magnum. Maybe even a .40LA. I am shooting for a nice, slow, stable flyer, suitable for training a 9 year old.

I am going to swipe the servos from the SPA3DT I started. I'm going to shelve that thing for a while.
