3D PRO Hummer, Whats the gear pitch?

rotaryguy · Mar 17, 2005, 08:36 AM

I called Century the other day and asked them what pitch the pinion/main gear was on the new 3D PRO, They told me they had no idea, they are made in Taiwan and they dont give us that information.
So I am asking you.
48 pitch would probably work but is it really? maybe .5 mod?????
any help would be great.

On a side note, helihobby has a couple 3D PRO's in stock with the motor and ESC for $199, I ordered one Monday.

It's 0.5 module on my Hummingbird Elite CP, and I think the 3D uses the same gear.

48p or 0.5mod yes

48p and 0.5 mdulus are not the same. The Pro has 0.5 modulus gears.

just got my 3D pro today and it seems to mesh perfectly with the align stuff...
.5 mod.
Thanks for the replies.
