Need help with gears
Hello all,
I am needing some help. I have ( actually I have 3- 90's and 2- 50's) a 90 tz frenzy that I am working on building but I am so lost at how to get the gears into the helicopter and what gears to use. I know this sounds odd but I have a ton of parts for the builds that I am doing and I can't figure out how to install the gears and the main shaft setup.
I have a red, grey and black gear but in most of the pics I see online it is a grey and red gear but I have seen grey and black and red and black.
It just doesnt seem to want to go together at all.
I am in Houston and will be more then happy to pay for any help I can get in person but any help would be great.

I am sure you would get more help if you posted the photos of the gears and the helicopters. From what I remember the TZ90 shared parts with the Raptor 90 it might have the installation process.

You make me confused.
The problem is not colors!

Gear ratio is the main concern.

If gears fits both directions... To the tail system and bell pinion, so it is OK.

The colors is the fashion choice...
