I'm building an E*RaptorCam for another member on the site (of whom may name himself if he chooses).

Since I was starting with a new kit it gave me the opportunity to easily make a few mods that I have been wanting to do with my ship.

I've removed material on the frames where the stock nitro engine mounts up to. It serves no purpose and shields airflow to the electric motor.

I also cut a 1.5" lightening/cooling hole in the curved fan shroud area. This gives direct cooling to the motor when in forward flight and should allow the escape of hot air near the motor even while hovering.

All totalled I've shaved 1.9oz over stock frames. I suspect frame rigidity is slightly compromised but I say slightly... and we're not slamming these things around for 3D type flight so I really doubt any difference will be noticed.

You can save anothre 3 ounces if you use the CF skids (PV0101) and the CF boom supports (PV0103).

I think the structure will be fine, with the mods you did. As you said, we're not 3D'ing these things. :)

Just test flew Will's Raptor under the street lights. Motor temps are about 15-20° cooler than mine. It would appear that the cooling hole and removal of the frame has made a difference. I need to do it to mine now.

I must say I am extremely impressed with the smoothness of his ship. This one is going to take little to no tuning. It's already rock solid. No buzz in the tail or landing gear... nothing. I'd like to keep it for myself and give him mine!!!!

I'll post up video from this ship tomorrow
