Sorted now & guess what weather turned but clearing up midweek so I have changed a few things. I took thr motor mount off & put the motor back in the original place as putting it further back added more weight to the rear of the CG.
Needing more ballast in the nose.
This thing already weighs 375g all in without lipo. I need to add about an ounce or a bit more on top of the lipo weight to get CG or atleast a bit nose heavy.
Why not ardupilot? What are you trying to accomplish?I am not having a good experience with iNav.
Delta wings are dirt cheap to build. Dollar Tree foam board is only a dollar, need 2 sheets.
It was too damned fast and needed a lot of room though, had to go a 2S lipo and a smaller prop.
I started cutting one of of these slo-fly planes, they look like fun.
