VT2750

Introduction:

This was inspired by a project called the mini q-bit. I've always wanted to do a vtol, but the flight control softwares I have the most experience with (betaflight & inav) do not support them. I thought this was a clever compromise. The best part though is the ability to quickly swap wings in and out for testing.

Components:

• ZJWRC 115X frame

• BetaFPV canopy

• RCInPower 1207 5000kv motors

• AuroraRC Supra-F4-12A AIO

• Frsky xm+ receiver

• Runcam nano 2 camera

• Happymodel whoop vtx

• 3d printed pegs to hold the wings

• various wings from dollar tree foam board

Conclusion:

98g dry without wings. 15g for the small set of wings (113g with quad dry) or 27g for the swept wings (125g with quad dry). The major difference between this and the qbit aside from missing the cool carbon wings is the lack of the dual cameras. I didn't have the camera switching board, but also felt the extra weight wasn't necessary for a simple takeoff and landing process. I'll need to see how it flies to see if my mind changes. The pegs holding the foam board are taped. It'll be nice to have something more custom if this thing actually flies well. Other than that, it uses the same configuration with the vtol mixing done on the taranis side.

Update 9/24/20: I was able to maiden this with the plank wings only. The hover and transition to horizontal plane mode was ok, but there is an issue with the pids such that when I tried to turn, it would spin out of control. I figured this out after the 3rd flight/crash with the goggles and tried to do it LOS. I wanted to lower the pids, but the battery strap broken after the 3rd crash.

Update 9/26/20: I am still unable to get this to fly. Lowering pids do not seem to help. Same issue while turning.
