In Response To: motors (john)

1.5 gears are what most of us are running on the 6BTAs. The ZF IRM 220A gears at 1.53 are a popular gear, that's what I'm running with zero problems in 14 years, other than the two short steel crossover hi pressure tubes on the rear will rust out if you don't keep paint and CX on them. You can spin 21 x 22 three blades with good performance and no overloading the engines.
