After extensive research, as a complete nu-bee to helicopters, I found that the slant 700-800e main gear could be used on my Align 600esp. The lite construction of the stock and standard main gear and the smaller toothed .6 MOD with limited selection of pinions used on a 6mm motor led me to search for an answer to my new gear choice . I realized I needed to change my one way bearing hub to match the new slant gears. I'm running my set up in a heavy sizeable semi scale build and wanted as much power and torque as I could find and then realized with my search, that these straight toothed gears are loud for a scale project. So a long story short ended up changing all my drive to slant gears with a 1 MOD and hopefully a much quieter drive set up, allowing for more rotor sound and less whine of gears.

Awsome replacement part
Perfect as always! Heli Direct is my go to for replacement parts. I have never had a problem with Align replacement parts. I used these on two of my Trex 600's I have converted to Gas from nitro that run a Trex 700 main gear.

What ever happened to the model helicopter market?
The Align market parts work great as always, no problem here. Where are all the good deals and clones we used to see?
