Hi,
I'm making an MAV with two Bronco electric motors and I'm getting a lot of trouble with torque because I only have one type of prop. I'm using 6" x 3" Micro Invent carbon ones. Does anyone know where I could get left and right hand props of a similar size and pitch? As a last resort, I could make my own, but I would rather just buy them. Thanks!

APC makes a pusher in a couple sizes close to what you want;

LP05545EP
5.5x4.5EP
Spd400 Electric Pusher
$ 3.19


LP06040EP
6x4EP
Spd400 Electric Pusher
$ 3.19

You would also want the same normal prop;

LP05545
5.5x4.5
Speed 400 Electric
$ 2.13

LP06040E
6x4E
Speed 400 Electric
$ 2.13

anything lighter? the airframe is about 25 grams, so its pretty light and those props look awfully big. the props im using now weigh .85 grams but i'm going to venture a guess that the APC ones are many many times that.

Hmmm, how about looking at some of the toy stuff in Wally world?

Also check out GWS and H O B B Y C I T Y. C O M Both carry smaller props, in tractor and pusher style, that are very lightweight.

Also try the electric side of the forums, there are micro forums there that may be of more help.
