K&B 35 series 75
« on: January 17, 2012, 10:04:42 AM »
Anyone have any setup tips on the K&B 35? Does not seem too popular a stunt engine and have not been able to find much info on setting one up for stunt? Any ideas? How about a muffler that would fit? Have to be a strap-on type muffler, any ideas on what might fit?

Hi Shane,

The Series 75 was a higher timed engine similar to today's engines.  So I would expect to run it high rpm/low pitch in a wet 2.  10" or 11" prop with 4 pitch to start.

Pretty sure it is not going to be happy in a 4-2 run.

Bill, thanks for the info. Sounds like an LA run, without the ability to get aftermarket parts! ;0)

The Series 75 K&B 35 is a derivative of the popular K&B 40, which was a derivative of the K&B 35 Series 64 and 61. All have removable front ends, so the exhaust can be pointed either way. The K&B 35 S61,64 and the K&B 40 all have ball bearings. The K&B S75 substituted a plain bearing front end. I think that was a cost saving measure.
The K&B 35 Greenhead preceeded the S75 K&B 35. The S75 might have the edge on power. The Stallion was K&B's low cost answer to the McCoy 35 $5.95 special. The Stallion shakes but is a sturdy engine, good for sport flying.
I am running a K&B S75 on a Sig Skyray for carrier. I use an OS throttle. It serves that task very well. I have not tried one in a stunt configuration. It probably wouldn't have a 2-4 break. I have tried a K&B35 S64 with a 10-4 prop in a stunt configuration, and its adequate. But at 8.5 to 9 oz, I prefer an OS Max 35S, a Fox 35 or a McCoy 35 or 40. All are much lighter."

Years ago I had a great idea. Put the front end of a PB S75 K&B 40 (or 35 - same stroke) onto a ringed FI BB K&B 40. Lacking ballraces, I would get a lighter 40 stunt engine.
Wrong. The PB bits made it heavier! :(

Not too popular with the stunt crowd, but the Rat Race guys loved 'em.
