Both the original Moose and Super Rebel aircraft have a well earned reputation of being versatile airframes.  It is also the case that given the type of rugged service these aircraft are engaged in, we have designed a number of upgrades to provide a more robust and reliable platform.  With the significant horsepower and performance increases now being made available with our LS3 engine packages, these upgrades represent an important benefit for safe, utilitarian and cost effective operations.
