i havent thought about that from what u said i guess the 11, but from what I have been told the -6 want do 4 cell, the -8 will run 4 cell on stk ESC w/BEC. The -10 an -12s are bigger are they not?
Wrong, they just have different KV ratings. To get a reasonable headspeed with the -6 on 4s would be an 8 tooth pinion. the -8 would be a 10 tooth pinion. The -10/12 are MADE for 4s. I dont even think the stock 35A align ESC can do 4s?

If you use the 55-amp. Scorpion ESC. You can use the HK-2221-6 on 3S, also you can use the HK-2221-10V2 on 4S.

lol okay okay well can u guys tell me what motor/pinion I need to run 4 cell on the 450.

Cause I have been talking people on here like Centuryman and he seems very good with electrics. They all say you can run the -8 on 450 with stk esc, u just need a bec.

Im not saying I dont believe anyone is there some place I can read up on all this that will verify? Im getting down to wire I have less than 2 weeks to get this stuff so I can pack it for shipment to Iraq.

I have tried MANY different setups on the 450 and by far my favorite is this:

Scorpion 2221-10, 12T pinion
Jazz 40-6-18, 80% gov (3350 rpm)
4S 2100 18C packs

I also run T-Rex 500 on 8S, my favorite setup is this:

Scorpion 3026-1000, 15T pinion
Jazz 55-10-32, 80% gov
8S 2100 18C packs

If it's 5amps no problems. If it's 3amps you may get by with it.

Fender,

If you want great 3D performance with a 4S setup using the Align 35A ESC, use what beeflyer said - 12 tooth pinion with the 2221-10 (FYI, the Align 35A can use 4S). This will give you about 3,200 HS max (beeflyers 3350 RPM claim is probably for an unloaded head). Alternately you could use the 11 tooth pinion and get about 2,930 HS. This will give you excellent performance but not push the batteries and ESC so hard. You will get more flight time too.

You also can get very similar performance out of the 2221-8 with a 3S setup and a 12 tooth pinion (2,880 HS). If you go with the 2221-8 and a 4S you would need to use a 9 pinion. It will give you ballistic performance (3,190 HS). However, a 9 pinion may be hard to find for an 1/8" motor shaft, so it would be best to stay with the 2221-10 for 4S.

Best of luck in Iraq!
