170cc engine enough power for SD 40% Yak? - Page 2

gdavisjr69 · 05-24-2007, 11:15 AM

Donnie was giving weights for the 37.5% SD Models Yak, not their bigger 40% Yak. That's why there is a variation.

Comp ARF has a bigger 3.3 version 133'' wing span and is only about 45lbs if you want the Monster of all YAKs

No, he was talking about the 37.5% SD.

Got it, sorry.

I was talking about the 37.5%,I do believe that the 40%SD is quite larger than the Aerotech 42%er,the Carden is the smallest of the "150 sized" Yak's.

Having flown a 3W Yak ( 37.5% ) with the new 170 ( Not broken in ) its More than enough!

Sorry to derail the thread, but that is some BEAUTIFUL scenery FLYNYAK. Is that at your field or your house?

That is the Northeast R/C Flyers Club Field, it is in Troy Vermont. That is the ski aera JAY PEAK in the back ground. We are having are first IMAC contest on June 9-10 if you can handil the drive it will be a great event to fly in. I am trying to get my new SD 40% YAK trimed intime for it.

I flew the Adavanced IMAC sequence with a Comp ARF 3.3 yak/DA150 on pipes combo and it handled it fine. Didnt have gobs of power but handled it fine if you did the right thing on the sticks

SMOKEY · 06-06-2007, 04:42 AM

I bought the yak. Now i need to decide on the engine. What is the weight of the plane stock with a 170cc? Anybody use a Kroma 180? Looking for options.

Thanks
Smokey

I have a Kroma 180 in one and it weighs 48 pounds. The engine runs great. Very smooth. Has plunty of power for all 3D stuff. Pull out from a hover is good enough but NOT balistic.

R Nick.. Did you do a stock setup on the plane? I plan on using carbon fiber where ever i can. How did it balance with your setup? What prop did you use with the Kroma? Sorry for the many questions
