Gov or no Gov for 425 and best motor KV?

[edhall]

I have a HV110 CC speed control and a stock Align control from my Trex 600 esp kit that I did not use.

I can seen to get the HS speed calc to work for me, (laptop is out getting new HD).

While I will probably stick with 425 size blades, is there a motor KV/gear set that will give me the option of running a Gov on my HV110 with 425 blades with the ability to change gearing to 500/500 blades, with out being horribly inefficient?

Would the 14t and no gov, standard gears, be an ok combo?

Trying to pick out the gear ratios and motor.

Hate to have to split the frame later.

Ok, I found the post with the Android App "RC-heli-gear-ratio".

Great program!

Now I just need to pick a Scorpion KV 3026 series.

1000, 1210, 1400, 1600.

I would like to not knock my self out efficiency wise, as I will probably keep this as a 430-500 blade size machine.



1210kv the best choice for 430-500?

Yes - I have one on my 550 mm bladed Hurri and you can gear it down low enough for a suitable HS for the 550s and you wold be able to gear it up for 425s
