26cc to 30cc engine for 73 QS YAk

[randy racer]

i love my 72" QS Yak so much i am thinking of building a 73" as soon as i can get one. i want to use a gas engine on this one and don't know much about the smaller gassers. any suggestions on engine from 26cc to 30cc as far as power, quality, service and weight.

thanks

Moki 24cc or 30cc.

magnificant engines. Runs like a dream and is reliable.

P.s. the 24cc has the power of about a 25cc and even more with tuned pipes. Sounds better aswell

Randy,

Quique likes the RCS 1.4 or the small Evolution gas engine I think. The instruction manual will be released by the end of march or early April and you will see the recommended gas engines in it. RTF weight with gas engine shouldn't be more than 12.5 lb. By the way this plane is better than the 72" so if you love your 72" then you've got to go for the 73". There is a waiting list already on this plane. All you need to do give them a call and put your name on the list without paying anything and if you changed your mind down the road there won't be any problems. I owned 2 Nitro Mokis and I loved them, if their gas engines have the same quality of their nitro engines and they are not heavy I don't see why not. Hope this helps, Reza

thanks guys, have any of you ran the RSC 30cc F180 there specs say it come in at 56oz and will pull a 18-8 to a 20-8 prop. i haven't heard any thing good or bad about there engines. well i haven't heard any much about any of the small gassers. any input would help

thanks

Quique uses a YS 140 in his instructions I think this plane will fly great with a lightweight gass engine.

yes.....brick!

You can`t forget about 3W24. It`s a little bit heavy but still a great engine. I have one lying on the shelf and waiting for a plane (also thinking about 73" yak). Do you know if the pefa canister would fit into the fuselage of the yak.

youngflyr, what do you mean by brick? when ralph works on the G26 it comes in at 2.5lbs with elect ign and muffler i think.

stiopa, it would take alot of work to put the pipe in fus. it's not made for it. i think it would add to much weight, this plane needs to stay unde 12lbs to fly nice and i think it's going to be close with agass engine.

What about the OS 160?

[ShortBus]

This plane flies great with a YS 1.40.

Ahhh, to young again..
15 years old and already knows all about engines
My "brick" G26 turns a Mejzlik 18-6 at 9000 with a Dale Abell muffler and will pull 17+ lbs on a spring scale at the tail wheel...
Come back in a few years when you find out that maybe some of us old people indeed know something....
