This engine has been a favorite for pattern pilots for many years. The new design of the R61F SPEED/13 provides increased power and performance over all previously produced .61 engines. Available with a venturi or with an R/C 9mm carburetor with in-flight mixture control with a dedicated servo or in a 10mm carburetor version. Specs: 2.5hp at 18,000 RPM. This engine is tuned for top performance with a new crankshaft, advanced timing and under head design.

Select the muffled tuned pipe in full length or compact design and the manifold of your choice. We responded to the requests of classic pattern pilots around the world and introduced the new Classic Pattern 40403 header that gives a rise of 2 inches in height for additional clearance for the tuned pipe. And, recently added a 3" rise header, model 40402. The Novarossi Model 40400 is a straight exhaust adapter and model 40401 provides a gentle S curve to raise the pipe approximately one inch.  Custom headers of any height are also available. Call or email your specific airframe requirements. 

 White case engine available upon request. Identical specs.

Available with 9 or 10mm carb's and in a freeflight and control line version with venturi.
