Sukhoi SU-26
Just completed a build on a Carl Goldberg Sukhoi SU-26. The plane replaces one I crashed a month ago. It is my third Sukhoi and is powered with a Moki 1.8 CID using a pitts style muffler. The radio is a JR and has 4131 servos. A pull pull system on the rudder with individual servos for each elevator and each aieleron.
I plan to fly this plane as soon as the weather here in Savannah, Ga. will allow. The vertical on this plane with the Moki is unbelievable. There is not a manouver it cannot perform.
I also fly a Carl Goldberg Bucker Jungmann with a Saito 1.8 four stroke. Vertical not a problem here also. This plane is seven years old and I hope the Sukhoi lasts at least that long also.
Happy flying to all,

RE: Sukhoi SU-26
Hi Jim. Its good to see another one ready to go. Do you have any photo's of your plane? Where did you mount your two elevator servo'c and where is C of G at from the leading edge? I'm just finishing up mine. Power will be from a Satio 180. I'm just getting ready to clearcoat plane. I still have to paint the cowl and belly pan. Bob

Bob,
I will post pictures tomorrow, weather allowing, or just take it where the plane is hung from the ceiling in my building room. More information tomorrow.

RE: Sukhoi SU-26
Hi Rob,
I am responding to your request for pictures and CD location. First let me say that I always start with a nose heavy Sukhoi. I have the CG on the first outing 1.500 inches in front of the main spar. After several flights I start moving the 300 ma/hr battery pack aft a little at a time.
I have attached pictures for you to view and have one comment about the Saito 180. I went to a 16-6 Semitar prop because I needed to reduce torque on my Bucker Jngmann. I started off with a Mejzlik 16-8 and it torqued left so bad it was difficult to accelerate on a vertical, tried a Master Airscrew 16-6 wood and it improved and wound up with the Semitar. No more issues on torque.
Hope this helps,

RE: Sukhoi SU-26
Hi Jim. It looks good. I was thinking about painting a red nose on the cowl there too. I'm just trying to get a feel for everyone who built and flew these planes. Thanks for the info on the c of g and prop size on the 180. That engine must get some pretty good rpm's with that prop. I haven't had too much experience with this engine. I see you have your elevator servo's mounted on the back too.
