I was thinking of doing something along those lines too. The canopy does transmit the sound a bit more, so it's a lot louder with it on.

I wonder about the ground effects, and how this handles with the canopy OFF, and the training gear ON? I know that in my garage, where space is a lot more limited, the ground effect is much more than outside in the open.

After all that....the canopy does serve another purpose. My LiPo sticks out a bit from the frame, and when I crashed last time (really just a hard landing) it dented the front edge of the pack. The canopy would have protected the pack in that case. I don't want to puncture my pack.

Maybe this weekend I'll get that heat sink vented!
