UKIE,

In your selection of engines, the Fox 35 and 15 Schneurle are probably the most practical to bash around now - parts are available.

They are also quite good for the purpose. The Fox 19 - I presume the 4-bolt backplate, baffle piston engine, is also a dandy, but, again, parts may be a mite scarce.

The 15 Schneurle weighs about as much as the Stunt 35, and if you insist on winding it up, it can give about as much power. BUT, at a whole different RPM range. The 15 Schneurle is a good engine for what we used to think of as smallish 29 size models - it is too much power and a bit heavy for what we once considered 1.5 - .19 models.

Fox engines work best on an oily fuel - the Stunt 35 on at least 25% castor; the 15 Sch possibly down to 22%-25% total oil, mostly castor.

C'mon home to CL. The friends are among the greatest modeling buddies you'll ever find.
