Question:

hi I use a 131 ratio lenco cs3 tranny ,what ratio is this planetary I dont quite understand the calculations ,also do you have any large sprags or know how to get them any cheaper..Brook

Answer:

Hi Brook, I'm sorry .I should have listed it as a 1.162 which would be the ratio of 4TH gear in a 5 spd. or 1.162 x 1.199 x 1.25 x 1.31 = 2.28 low gear. The last I saw the helicopter spags were over $800.00 I will see if I have any to sell.Thank You Terry
