I finally decided the other day to do the Micro Sumo 3d w/ the turnigy 2204-14t motor and 10 amp esc. I'll post pics as i go so those who havent built one can see it.





I havent cut my control surfaces off yet waiting on my wing tips to finish drying just slid it together for the pics. This is the motor and speed controller i will be using.


Please post any opinions. Any prop suggestions would be welcome.

I started putting the electronics in it today hoping ill get to fly it tommorrow. Im already impressed with the ease of the build and i really like the size so far. Kind of aggravating trying to figure out where to run everything. If someone knows where the battery normally sets pls post and let me know

I have some of that foam. I was thinking it would work on a smaller build. Hope to see it flying soon.

ok need help someone. I got everything ready to go and now i have a flying problem. When i tried a vertical take off it will not lift. when I tried to launch it strait to the ground. Obviously not enough power or something. When I first put the motor on it was spinning the wrong way. So I swapped the middle wire and one of the sides. At this point the motor was spinning the prop the right direction. Dont understand why I dont have enough power to lift the plane.

The motor is a turnigy 2204-14t with a 10 amp esc. I know you should not ever cut a prop down no more than necessary other than to balance a little bit but the 8040 prop was to big for the hole so I had to take a little more than usual off each end. Would this be the problem. I tried running it with a two cell lipo 7.4v 500 mah battery. Then I switched to a 7.4v 800 mah battery. Still got the same results I didnt want to try a 3s because of the weight.

Does anyone have any ideas.

Are the letters on your prop facing to the front?
Yes, I've known that I'm "different" for some time now...

hey dtribby checked and the numbers were facing the front. I even checked to make sure the motor was spinning the right way and it was. This is the first pusher plane I have tried to build. So my only other option is to wait for a 8x4 prop to come in so its factory cut and im not cutting one down. Thats the only thing I know to do for now. I also ordered some lighter weight servos also.

What's your AUW? That motor is designed to run a plane of no more than 8oz. The cut-down prop could be making a significant difference, too. You might even try a small 3S battery if you have a 7x4 laying around, or of your cut-down prop is close.

my auw with battery and everything else was 7.8 oz. But i checked my prop and the overall length was 6.5 inches so its the prop no doubt. So i put this one up on the shelf till i get my props and smaller weight servos in.
