u can also go ft spear vtol version , it has good space for flight controller and I have built a 80% bronco tiltrotor vtol , there were issues with the space for mounting the flight controller and and placing the battery , while maintaining the cg

Ummm vtol is just having more thrust than weight. My Sponz bloody wonder with a C motor and 11"prop does it just fine if it doesn't fall over before I add power.

So my mini Guinea VTOL did not work (it was not stable and barely lifted off the ground).
Here are some pics of the prototype. So I'm back to a normal plane, and guess what? its still a VTOL.. just stand it on its tail on long grass for the take-off, and for the landing just do a flat-spin all the way to the ground!
I love to fly the mini Guinea BTW;)
thank you all for your replies:)

Happy maidens

If your thrust is on the CG,  AND the tail feathers are big enough you dont need the rear motor on a swing wing. You can have the thrust a wee bit aft of the CG if you can tolerate going forward when going up. Definitely need differential speed control to make things easy. Look at the Marines Ospery for design clues.

Never thought of a flat spin, but thats going down fast enough to break things, sometimes. Was approved procedure for Scud running provided the clouds didn't touch the ground

Tail setting was the go to method of launch back 5 years ago at flite test

Thanks for the input, I will look into it. for the flat-spin landings I just put full up elevator ant it comes down rather slow.
