Did you order it with the Fan?

If so the Prodesign 90mm fan has a molded in cut-out for the install of the outrunner motors. No mods to the fan needed - Nice touch.

I have tested the Scorpion in this fan on 6S I get 1550 watts at 50 something amps and the motor is nice and cool. I plan on testing it on 7S tonight and getting temps and numbers.

Also have the Het motor and I believe you can run 7S on that one with heat sink installed. Yet to test it

Will post them on my F-18 thread.

So I am a bit lost on what motor I should match up with my Midi Fan.

So I am getting ready to build my Pro Design F-18 and I have been reserching setups for weeks now looking for that balance of decent speed and power but tollerable flight times (6-7 min mixed throttle) and I am kind of stuck! Rough estimates have the jet coming out at about 7lbs with 6s and 7.5lbs with 8s. I want to keep the motor budget at a reasonable price (would like to stay under $100). I really am thinking 6s so I have the convience of charging 1 battery not 2 (2) 4s's to make up 8s) soooo Battery will most likely be 6s 5000 30c. I am going with a CC ICE 100 ESC so I can run 6 or 8s.

Neumotors are just to expensive, Medusa is out of buisness sooo I am looking at: (with some flightcalc specs on 6s 5000mah 30c)

HET Typhoon 600-37 (1700kv) 4.1lbs of thrust and 162 watts per lb (pretty weak but good flight times) $89

Great Planes Electrifly Ammo 36-56-1800kv 4.4lbs thrust and 184 watts per lb (better but not great but still good flight times) $49

The Scorpion motors (hk3026) are outrunners and needs quite a bit of Fan Modifications to make work so not sure about that but the price and specs are decent, not sure I want to hack up the fan!

Hobbyking has this:
KD36-74-09XL (1900kv) 5lbs of thrust and 220 watts per lb and still ok flight times the $31.95 price tag is just dosent seem like enough money for a motor of this size???

So can anyone make some suggestions and please dont just throw out a brand with out a model # that would work on the Midi fan.

Keep in mind if I have to I could go 8s but trying to stick with 6s

Thanks for any help,
