Will the 766 auto gear 127T interchange with the E7SE 121T main gear?
Has anyone tried this yet?
I already asked a couple of people and they did not know.
I asked the website and got no response.

Thanks in advance.

The 139T fits the hub, but you will need to drill 4 holes in it.
unfortunately it is just too big for the frame an canopy. It could be made to work, but surgery is required, motor mount needs to move, tail boom mount needs to move etc.

Just curious.
Wwith a 12t pinion you get 10:1 with 121T
With a 127 T you would get 10.5:1, really not much of a difference.

What is your application? It would be much easier to get a lower kv motor if you want a lower headspeedTeam Synergy, Team FBL Rotors-------if its not broke...it will be!

I am currently running old t-rex gears 170t/12t.
this gives a 14:1 ratio. and a real nice 1800rpm with the 1175kv motor.

If I put the stock 121t/12t gears on with the 1175kv motor (the recommended set up) the head-speed would be closer to 2500rpm.

It flies the way I like it at 1800rpm.

I could just get a 800KV motor I guess.
