For the price point on this engine, it is exceptional for an RC basher. I am running this in a Tekno NB48.4 buggy with a. Hypex B5 header and hypex 2135 pipe... Great quality and machining. I definitely recommend this engine and I've run many engines at all price points in all types of RCs

This is a very good engine made by Golden Lion that makes the LRP. My USA1 make wheelies on 2nd gear on a rich tune. You need to do a good break-in as they are super tight at list 6 tanks on idle then 2 tanks on the road. Sleeves are very cheap in case you need them.

What reviewers say

Reviewers mostly rate this .28 rear-exhaust engine highly, praising its power, machining quality, value for money and ease of tuning once broken in. Several note that a thorough break-in is needed, with one reviewer advising lengthy idle and road runs before use. Reviewers mention good parts availability and inexpensive sleeves. One verified owner gave a 1/5 rating, reporting persistent idle and carburettor problems, vapour lock and difficulty tuning, and said support advice blamed the user. Overall sentiment is strongly positive, but the single negative review describes a recurring tuning and idle issue.

  • + Strong power output
  • + Good machining and build quality
  • + Good value for the price
  • + Easy to tune once broken in
  • − Requires a thorough break-in
  • − Idle and carburettor issues in one review
