The MA-1A Start Cart (also referred to as a “Huffer”) was used by the United States Air Force as an auxiliary jet engine providing a source of high pressure, high volume air (called bleed air) to start aircraft without starters, and to start aircraft that have inoperative starters. The F-4, A-4, T-38, F-104, and A-7, just to name a few, had to be started using this cart. I have used the MA-1A many times to both start the above aircraft, and to troubleshoot/operationally check the bleed air system on the C-130 aircraft.
The kit comes with 17 resin parts and 10 photoetched parts, with molding in crisp detail. I found no fit problems with the parts, and the kit went together fairly quickly. Be careful with part number 2 with its long “tongue” at the top - I accidentally broke mine but was able to easily repair it. The body of the cart is molded in one piece.
