Just received my first Dust... Thanks to Salmonbug.

Gonna power it with my West .50.

Hopefully shooting for the maiden this weekend (if all works out well)

Any particular points of attention or mods you Dust specialists recommend when using powerful engines on this thing?
The engine mount and surrounding structure seems awfully light...

I made some engine rails that went back and intersected the bottom of the wing, then tied those together with some thin ply. Made kinda like a half nacelle under the engine. Of course my carb was in the rear, so I had removed much of the firewall, I had to do something to strengthen it up.

I CA'd some thin kevlar onto the engine mount area. The only other thing was 8411's and a HS85MG on throttle, with antenna tube used to the throttle linkage. Forgot the designers' name, but he told me the light construction and vibration of a big engine will eventaully take out the servos, and he recommeded the antenna tube to minimize vibration to the throttle servo and high end servos as they hold up better. That was 2 years ago and she still flies awesome. Here's a pic where you can see the kevlar & throttle tube, and yep that's a K&B 48 - it's considerably faster with it than a Webra 50 [sm=confused.gif]

I used 1/64 ply top and bottom where the engine mounts. I also used light glass over entire mount. My first Dust had over 100 flights on it and held up well except for failed take offs and bad landings.
