outboards

[Tunneljunkie]

I am looking to get into 3.5 stock tunnel racing. my question is which outboard seems to be the best for stock class? I do not intend on moving up to modified for quite some time so i need to make the best choice possible....... Tks

I have a very old Thunder Tiger 3.5 on my Dumas Hot Shot Sprint. Been very good motor.

The O.S. .21 outboard unit is also a great stock class tunnel motor, and it can take high nitro fuel to increase it's onwater speeds. Jerry Dunlap does regular outboard/tunnel articles in RC Boat Modeler Magazine and has done testing on the O.S. with good results.

Hope this helps,
