I am seriously thinking of a 3m comp arf Yak! I have a problem though! I have got the overpower bug like everyone else and I don't want to go back! I know that the specs call for a 150cc! But seriously! Is that enough! Videos would be nice! Comments work just as good! Thanks ahead of time! |

Hey Double A...Having done a complete build of the CompArf 3m Yak 55sp on Flying Giants
http://www.flyinggiants.com/forums/f...5sp-build.html
and now having 45 flights on it, I can say that the DA 150 with MTW 110 mufflers will pull the plane through the (IMAC) Unlimited sequence without problems. However, as other pilots above have indicated, you won't get an "overpower" situation, which you love, with this combination. Because of the large cowl & also the baffling which is used (on mine), there is a trade-off... You won't find the Yak speeding up like an Extra/Edge with a streamlined cowl, but she will keep on pulling at a constant speed.
On the DA 150, (on prior CompArf's) I had used a 28x12 three blade Mejzlik, but on this baby, it just did not work. I have settled into a 30x12 Mejzlik 2 blade prop for now & I'm awaiting the release of the DA 170, which will certainly be attached to this airplane as soon as I get it.
