e-flite ultimate 3D profile, prop, gears, motor?
I am putting to gether the eflite ultimate 3-d profile... and am upgrading to a himax HA2025 4200 motor and a new gear box that allows for different ratios... my question is which ratio would be correct for a APC 11-4.5 prop? I am using thunderpower 3 cell 1350 pack for power and a CC-25 speed controler.
The available ratios are
4.43:1
5.33:1
6.6:1
I know it is a newbie question..but I am a newbie... I have looked at some of the free motorcalcs.... but holy cow... I have to enter so much data ...much of which I don't know.
So any help here would be awsome.

I have been using a 6.6/1 gear ratio with an 11 X 4.7 without any problems. Also used it with an APC 12 X 3.8 which I liked better for hovering until I broke it on a rough landing, so been using the 11 X 4.7 until I purchase a replacement.

thanks for the reply... my buddy has been using all three ratios with no problems... yet... I wanted to get it right so I don't burn anything up. He is using the other ratio's as spares when he dings the gears... I thought that might not be to wise so I asked the question.
