Replacement for a Fox 35

I have a Twister with a Fox 35 on it. The engine has been acting up and I was curious what other brand of engines would bolt up using the same bolt holes. The fuse has a tripler with blind nuts so I am pretty much stuck with the 35 bolt pattern.

No, you're not. Drill through engine mounting holes, taking wood and blind nuts out. I'd use a 1/4" drill. Now plug holes with lengths of hardwood dowel, even not-so-hard stuff from hardware store will work, but one can make them from maple.

Once plugs are securely glued in place, trimmed flush, you're set for next motor. Good trick for the ARF Flite Streaks, but in that application we do it to a new model (kinda soft motor mounts sticks in these models).

Acting up? How? If it worked well before, something has changed and it may not be the engine, itself.

New plug? Check the fuel line. You DO use a filter, right? And it's clean? Fresh fuel?

The only engine (to the best of my knowledge) which uses Fox mounting holes is the DoubleStar .40 -

The Thunder Tiger 36 and Magnum 36 will fit Fox mounts. They are, however, heavier and have longer shafts so will require a bit of weight in the tail to restore CG. Lots more power though if your'e interested.

The older I get, the better I used to fly!

Presuming you think you need to replace your Fox .35 with a better engine for some reason, the best I can recommend is an L&J Fox .35.

Everything is the same, only better.

L&J Fox 35? Where to buy ? How much? What makes it better?

pelham: Try Eric rule at RSM Distribution or Manufacturing on the internet. CRS is kicking in again. He carries them. Just maybe Leonard might have them also. -DOC Holliday

Yeah, Baby!

> How much?

$139.95. It's gone up a bit, used to be $110 or so. I was lucky enough to have Larry rework some old Fox .35's, now they are better than new. I forget the actual detail, but Larry told me how many hours were spent using sophisticated equipment developing the Hemi Head.

> What makes it better?

They have been reworked by someone who actually flies control line at the competitive level, i.e Larry Foster. These engines have been tuned to produce the reliable power and high torque needed for competition C/L stunt. Modifications include deburring & blueprinting, lapping piston to cylinder, balancing crankshaft, retiming ports, adding hemi heads and backplate stuffers (where necessary). Every engine has been bench tested and test run and comes with a one year warranty against defects in workmanship.

If you would prefer to have an engine you already own tuned by RSM just give them a call at (951) 678-1406 and get a quote on the average costs involved.

There is a lot of literature in the SSWF archives about how good these engines are. The really trick setup would be to get one of the new hardend crankshafts to go with all the rest that L&J do to the engine. Do a search on "L&J Fox" in the title and see what you get.

Yep, they run just like an OS .40 FP.. (But weigh less, of course.)

Larry Foster's engine work is superb. But I thought he had decided to stop reworking engines for awhile.
