Moose Mods

Structural Upgrade Kits to build your Bull Moose, Super Moose or Monster Moose.

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.

​​Fuselage Upgrade Kits by MooseMods.
Bull Moose and Monster Moose

This kit includes all necessary forward skins and internal structural upgrades for the use of the LS3 430 HP, 480 HP, and 525HP upgrades.  Included are new pre-cut door posts of .130 channel, and internal and external door post skins of .063 6130-T6*, .063 boot cowl skins, additional .032 forward belly skin, upper engine mount carry through boot cowl area to HD Door Post structure, rear fuselage channel reinforcements, tail section stringers and doublers, and a .032 extended tail skin. These upgrades will increase empty weight by approximately 25 pounds.

NOTE:  These prices are subject to change depending upon ongoing material costs increases.  An order must accompany a 50% down payment.  Balance due prior to shipping. Allow 60 days from order to shipping.  

NOTE: With the exception of the Heavy Duty forward door post channel and skins, “V” brace and engine mount carry through, all of these upgrades may be installed on a completed Moose or Super Rebel airframe without removing wings or windshield.  Information will be provided with each kit describing best practices for installation of each element to be installed.  To install the HD door posts and skins, “V” brace and carry through hardware to the engine mount in an existing aircraft, it is necessary to remove the wings and windshield.

Further note:  Most if not all of the Bull Moose upgrades may be applied as well to the Super Rebel and Yukon airframes.

Generally speaking we can ship an upgrade kit package within 60 days of receiving a 50% deposit. Order will ship or be available for pickup with payment in full.  We are happy to have funds wire transferred, or will be glad to accept a personal check. As soon as funds clear the process begins.

As always...feel free to call with any questions.
