Amazing engine! 1 gallon on it and it’s a beast. Also no problems with the pull start?

So happy these are back in stock. High quality engine for a great price. Easy to tune and has tons of power in my savage x. Hopefully they stay in stock for awhile because I want to order a few more

What reviewers say

Reviewers uniformly rate the SH Engines PT2802A-P3 .28 highly, with all eight reviews giving five stars. Owners in Team Associated Monster GT, Savage and Savage X style trucks, and a Hobao SST truggy report strong bottom-end power, good break-in, and reliable running that holds a tune. Several note a clear step up from stock .21 or .25 engines. One reviewer who ran it in a Hobao or Kyosho MP10 setup warns that it does not fit the low engine mount without shims, and that the low-profile pull start on those mounts caused a failure. Reviewers also praise the build quality and fast shipping, though one has not yet run the engine. Overall reports are positive, with little disagreement in the reviews.

  • + Strong bottom-end power
  • + Good break-in and tuning
  • + Reliable running
  • + Solid build quality
  • − Does not fit low engine mounts without shims
  • − Low-profile pull start on some mounts problematic
