Design Assets:
This model captures the current “State of the Art” in Real World Snowmobile Racing Competition, all in ¼ scale size.
The chassis design replicates the REV in many ways, Pyramidal Upper Structure, front “kick-up” with High Torsional Strength and light weight.
Scale RAS front “A” Arm suspension and rear SC-4 has allowed this sled to do a perfect 21 foot jump at 1/3 throttle!

Light Weight, Realistic Sled has proven that an R/C Snowmobile is a very capable model when it is built like it’s “Full-Size” counter-part.

A Special Thanks to XTREME RC Car magazine for showcasing this model in their March Issue as a “Home Built” project.
