RevMax

RevMax is and RPM limiter from Model Avionics
The Rev–Max is a new concept . This unit differs from the usual engine governor and may be coined an "RPM limiter", or as industry often terms an "Over–speed Governor"

The Rev–Max does not govern an under–speed condition relying solely on the throttle curve for this function. The problem with all governors is a slight throttle lag. This issue has been completely addressed with this product.

The Rev Max limiter works better then any governor on the market today, superior midrange power is achieved resulting in a more positive feeling model. This is the only rpm limiter on the market that I know of, it`s very good idea which allows one to get even more performance out of their helicopter.
