I have a 9 blade 1750kv outrunner from my F-22 I'm not using if you're interested.

What is a drop in fit for this t45 that really wakes it up? I love the sound but not very fast at all.

If you must have 12-bld and must be drop-in, then try the 1835kv Freewing inrunner. Expensive and heavy, but good performance.

I have that in my F-22 and it tops out about ~109 mph at sea level in level flight. The vertical is excellent for 6S as well. I've not found any Freewing option on motors for 6S to give much better than 110 mph in level flight, if that, unless it's a very slippery airframe.

was thinking of swapping out motors for a higher kv motor. Dont know how the blades can handle that though...

Amp draw is momentarily >126A on my 1835kv motor w/the 12-bld Freewing fan.

I'll quit cluttering up your thread but with any motor with a much higher KV than that, you're going to have to swap out the ESC and you might not like the resulting flight times.

I dropped a 1750 kv 9 blade F-22 fan/outrunner in my Phoneix 90mm Hawk and only got 2 min flights on a 6s 5000, I agree with Mizer. I do have a Stinger 90 12 blade fan/esc for sale though if you want it

Anybody feel the 90mmJP hobby fan 6s would be good for the t45? I have one, it will fit but it’s about 2.7 ounces heavier. I was going to try the 1835 from freewing but $159 is a lot when you have JP 90.
