Try looking for it on ther web site or on tower hobbies or sumthing

The Mammoth's stock XTM 24/7 Engine can use the Savage21 or Savage25 Roto Start system, direct bolt on.

Who makes XTM/HPI engines?? I'm guessing that they have to have a common lineage if the back plates work, though it's odd that the XTM 2.47 is so well-regarded while the HPIs are kinda so-so.

Are they Italian? Japanese? Chinese?

Seems there are only a few "real" mfgs., just wondering who makes these.

HPI engines...I think Force makes their engines...I mean the Force .21 and Force .26 are exactly the same as the HPI ones in the Savage's.

XTM's engines are made by SH Engines in China actually...SHOCKING ISN'T IT? XTM and SH probably used a Force engine to design their engine. It's not an exact copy on the inside, but the Pull start is similar.

1 major difference...Force/HPI uses steel backplates, while XTM/SH uses plastic, nothing wrong with plastic though...

Also another fun note: SH Engines makes the Mach .26 for Dynamite/Losi/Horizon Hobbies.

Ofna makes a backplate specifically for the XTM 247 (part number 50010). It moves the shaft hole down to the side center of the plate instead of in the corner- a much better reach for getting around most exhaust headers. Here is a great deal on the whole package:
