 |  35% am yak engine choice
Just bought an aviation models 35% yak. Need to know if a 100cc engine is enough to fly 3d or do I need to go bigger? Has anybody tried a BME 115 in their's yet? Any input will be helpful.

I have seen one fly with a 3w 106, and it was plenty, would pull out of a hover pretty good even at 28.5lbs before fuel. A 115 would be great too, if you could get it to balance.

Yep, any of the 100 class engines is plenty, DA100, 3W106, BME110/115. The 110/115 are very light, you may need to run a heavier spinner or add some weight up front to get it to balance correctly.

The one I saw was setup with a 106 on cans, 2 2400 fromecos for rx, smart fly power expander, 2400 on ignition, mejzlik 28x10 and tru-turn spinner. No carbon wingtube, gear, etc. With a carbon gear (the one that AM sells, not graphtech), carbon tube, stock mufflers, I think 27lbs is achievable with a 106. You could also run the BME 115 and a set of cans, which would weigh what the 106 does with stock mufflers, and the cans would help the cg come forward with the BME 115.

The plane is setup for a 3w 106 and that seems to be a perfect match powerwise. It has more power than the DA and the weight it perfect to ballance the plane. The newer AM yak are coming out in the 28 lbs range. If you go with the carbon gear and li-ions you can get this plane down in the 27's. With 2,223 sq in of wing area you will have one of the lightest loaded planes out there in this size range. Garrett Morrison |

Yeah I wouldn't put a DA-100 in it either. 106 on pipes!
