An improvement kit for the Dragonfly a/c from China. It is a weird model, made from some flexible foam. I don’t think it is sold any longer. Mine refused to fly properly until I taped the wing leading edge. Too coarse surface I guess.
Edit: Actually my Dragonfly never flew right and I now believe the fault is with the floppy sabiliser, fin and control surfaces. The ailerons are quite flexible too. The last crash was final so I do not know if fixing those things would've helped.
The engine is originally out in the open and will be filled with dirt very easily so I designed a cowling.
Attach the firewall to the plywood first former with glue and wooden screws. There are recesses for the screw heads in the back side of the motor adapter. Check fit here.
You will need 4 short M4 nylon bolts for the cowling halves and 4 short M3 insex bolts for the motor adapter-firewall joint.
Also the fuselage is very narrow, an exterior fairing for the ESC was needed. It will improve the ESC cooling too
