Model Forum / Radio Controlled / Land Models / November 2007

Hopefully others will chime in here, but, if it's of a decent brand, it
will do fine unless you're into competition. Ofna, HPI, OS, RB,
Novarossi, , all good engines, as well as others (I've heard good things
about Axial and Sportwerks, and Mach 427 engines, but have never played
with one myself).

Basically, .21 buggy engines all mount up the same, , but there are
always exceptions. To put a .28 in a buggy usually takes some modifying
of the motor mounts.

The one huge exception is Traxxas products, , they take their own
proprietary "mid block" engines, which have their own
clutches/clutchbells, etc.

Anyways, AE makes a dual-start motor that they say will fit that
buggy(.21 bx-pr) for ~$150.00. (might want to call them on it though, I
know dual-start is a tough fit into a buggy) I've never used one, but if
it is anything like the .28 they put in the MGT, it was super-easy to
tune and held that tune rock steady. Ofna makes a .21 for even less, ,
but I've never worked with one of those either.

All in all, I personally don't think you need to spend $250 to be happy
in the end, in fact, if you spent $250 on an RB engine, you COULD end up
with something you need a bit more experience to be able to tune easily,
as some top-end engines seem to be rather touchy.

Basically, .21 are buggy engines, and .28 are truck engines, with what
is left between them being one or the other on a case-by-case basis.
Doesn't mean they won't work, , or can't be made to work.

Hopefully others, who have been in teh hobby for longer than I, will
speak up, and point out if I made any mistakes.
