You've given me an idea. I may have to see if I can fit the stock spinner to one of these.

I ran my today with 2150kV inrunner.
One thing for sure, very power hungry motor. With 7x8 gas prop I got 128mph and at 2 min and 10 sec my 2200mAh 40c was dead. Not even enough power to turn around to land in to the wind.It was very light wind, maybe 3mph so there was no big deal.
Fun.

I was running 4s 2650mAh 35-70c nano the lipos ballooned up on the first run running 7x6 prop
I did try 7x4 x 7.7 prop in my other dog with 2036 kv motor and it was slower than my current setup
I think 7 inch pitch will be the max i want to run in this dog

Ive reversed the shaft on my 3026 and mounted it in front of the motor mount. It really helped get the CG forward. Cooling is much better as well.

Im doubt 4S will get 200mph. I reckon 175mph. On 4S Its around 1250W (15v)
5S (18v) @130A is 2340W.
I know its pushing it. The motor is only rated for 80A but Scorpions are known for tolerating alot more than their stated figures. Im not planning on WOT for long. I'll try 10sec at a time followed by a cool down period. The front mount will help. As long as temps don't go above 100*C it should be fine. I may be wrong eek.
Stick around - I should know in a few days time.
