Space ship?

[SportyModder]

Just putting this here....

It flys great, cg up 14" from the trailing edge....

power 2206 2150 kv quad motor, 800ah 3s battery, 2 sheets of adams foam board...

Scratch build? I've been thinking of something like this and here you are with it. If you have plans I'd like to try it too.

Yes scratch build....

30 inch wing span and 45* angles... I can draw up some dimensions if intrested...

You betcha. I'd like to build one 😁

Nice, solid design! Well protected prop blowing right over the elevator? Good stuff! Like the space ship/space plane theme too.

Thank you...

I am flying Elevons right now, and she does turn into a handful in slower turns (read under 75%throttle)
She is built heavy, and I think I may be able to lighten her up by 25% or so by removing some paper, and eliminating some glue joints.

Those compound delta shapes have funky stall characteristics is you don't give enough throttle on turns. I built something with a not too different wing shape and ailerons recently. As another forum member put it, the mid section liked to stall while the wingtips wanted to keep flying.

Drew up some basic plans on a sheet of foam board...

Test flight this morning I moved the cg back 1/4 "

Will fly a couple more batteries, but seemed to help with slower speed control.

Let me know if you need any clarification on any of the dimensions?
