Is this power setup realistic?

I'm currently running my Scimitar on an ICE 100 with the stock motor, 5s 3300, and an APC 9x9e. Static power draw according to the datalogs is averaging 95amps and 1600w at WOT. According to my inline wattage meter it's more like 78amps and 1500w - not sure who to believe.

Anyway...

The Power 32 motor is only rated for 60a and 600w continuous, so I'd like to get something more likely to hold up to the power being pulled and if I can pick up some speed in the process that'd be great. Having a high enough kv to be able to run a 4s 4000mah instead of the 5s would also be nice too. So I found this motor...

Castle's eCalc puts my current setup at about 4400 grams of static thrust and 136mph pitch speed, but it also only shows 66amps draw so I don't know how accurate it really is.

Throwing the Scorpion motor on there with only a 4s will yeild 4800/142 at 98amps with the 9x9, so I get a nice little boost in thrust/speed with the lighter weight of the 4s which will allow me to go up in mah and recover some of the lost flight time.

Am I overlooking something? I'm new to this stuff and kind of shooting in the dark while learning in the process.

Hi AWDstylez

With the Scorpion HK-3226-1400 Brushless Motor @ 4S and a 9x9 prop the calculated
motor current with my own motor calc is about 100 A. Details see attachment.

Best regards
Micha
