Hi guys,

I need some advices, I'm preparing my T-rex 450 for AP and thinking it might be a good idea to upgrade its power plan as well so i'm planning to use 4s battery setup since from what i heard and researched the stock align esc will do fine for 4s setup without additional bec (please correct me if i'm wrong). I already stretched my T-rex with 350mm blades and boom from G5


This is my motor candidate, Scorpion SCHK2208-34 Motor

Overall Shaft Length 42.5 mm (1.673 in)

So here are my questions
Anyone has any experience with this setup ? What is your flight time ?

What pinion i should for this setup ?

Any suggestion on the battery ? I'm planning to use Rhino 1750mAh 4S 14.8v 20C, It's cheap and it got a good rep

I'm looking for power and longer flight time so if you have other power setup suggestion, please do not hesitate

i notice some folks use outrage g5 power system, but i don't like it because it is really difficult to find battery for this system other than the outrage 6s 1300mah

Thx a lot for your help guys
