About the Samurai RM.1
Updated Internals
The RM.1 features smoother low end power with higher top speed, a steel backplate insert to reduce friction and wear while increasing RPM and providing a supreme stable idle! A strengthened black-coated crankcase to maximize durability and reliability! Additionally, the Samurai RM.1 utilizes a 3-port type ABC piston and cylinder that are specially designed to provide more torque over the power range!

The blue anodized cooling head with laser etched ProTec, Samurai and RM logos features a low CG (Center of Gravity) design providing a boost to stability and giving a more planted feel to the chassis. Another major improvement that the ProTek team wanted to bring to the RM.1 is the case durability that now features an all CNC-machined cast aluminum design to allow racers to push their buggies and trucks to the limit without having to worry about the engine case cracking!

Combined with this magnificent Samurai RM.1 engine are the racer's favorite ultra hot, performance oriented, ProTek P3 turbo glow plug and Samurai RM 21j "High Efficiency" carburetor that has proven to be one of the most reliable and powerful carburetors and glow plugs that pro racers can always depend on since 2014!

Fast, reliable, many carbs available. It's unbelievable. Cue the music.
A strong, dependable engine that stays perfectly in tune and delivers impressive power across the board, especially paired with the 2135 ProTek pipe. The EBIS version was out of stock, so I sent it to Drake for the break-in, and he absolutely nailed it. This thing flat-out sings.
All ten reviews are five-star ratings from verified owners of the ProTek RC Samurai RM.1 Maifield Edition 3-Port .21 Competition Nitro Engine. Reviewers consistently describe strong power, reliability, easy tuning and a good hold on tune across skill levels. Several mention pairing it with the 2135 ProTek pipe and note that it is built on an OS 2104 base. Some reviewers sent the engine to a specialist for break-in, and one reports 10-minute run times at competition events. Reviewers also praise the 21J carburetor and its availability in multiple options. Reviews are short and enthusiastic, with few specific details on fuel mileage, durability testing or comparisons with other engines, and no criticisms are raised.
