I killed all my gears in a crash among many other things due to a failed align speed controller. Now that I have learned my lesson about using a esc bec its time to rebuild. My question is what do I need to go to the slant style gears? Since I have to buy all of them what exactly do I need? I am confused at all the options and what combo is correct. I have a V1 converted to flybarless running the stock align motor and now a castle creations ICE100 esc. Anyone have a recommendation for a pinion?
Maybe someone can give me a correct part number list.

Thanks in advance!

You will need the following to use the slant gear on your 550.

Hey.

Having done this conversion myself recently I can recommend the 700E slant 12T pinion over the recommended 11T.
Also I think you will need the lower tail drive main gear and matching umbrella drive gears from the 600EFL. As I'm not sure the older gears will work on the newer auto hub, this I am going to test soon for the following reason.
With the tail gear change you also lower the gear ratio from 4.5:1 to 3.85:1 which then makes the tail less powerful and unable to hold in hard 3D. The cure I found so far is longer tail blades, I've gone to 95mm and then upping the governor speed in the ICE 100. Hence my recommendation for the 12T pinion to give the governor more head room to control rotor rpm.

If you do try the older V1 tail drive gears on the newer auto hub please let me know. As I gave mine away and need to get them back to try.
