I have a chance to obtain this k & B 61 and I was wondering if anyone might shed some light on it. I was told the owner doesn't know for sure how old or what model it is. All info is greatly appreciated,

Thanks, Steve "Dead eyes"

Another view.

That is a K&B .61 Model 6550 - great engine. I am flying one on a 7# airplane now and it will pull the plane straight up off the runway using a 10x7.5 3-blade

1984 thru 1992 or there abouts.
But the muffler appears to be to some other kind of engine?

Thanks for the replys guys. It looks like an O.S. Muffler but I could be wrong. I haven't seen the actual engine only photos. I was thinking about puttin it in An Uproar 60, what do you think ?

That would be a fantastic engine for an uproar-60. You will have to break it in a bit more than one of the Asian imports and tuning it will probably take a bit of patience.


I have a Mac Pipe on mine because the dang muffler is such a piece of junk! The K&B muffler is a two piece with the pressure tap being the only thing that hold it together - soft metal, + vibrations = muffler backend pops off in flight!

There is lots of information here in RCU regarding this engine.

Thanks for the replys and info.
