Thank erh.....I'm sneaking up on it.

I've run it a couple times, next time I'll put a clamp meter on it just to make sure she don't blow the esc then up she goes.

Thank you.
My amp draw is on 85 but I think it is slightly lower due to the condition of my batts.

Right. Thanks Graham. I have the 1200kv too. I was thinking this can go below 70a. Too bad.
I had the 1400kv on 8s, lots of power but amp a bit too high to my liking.

Has anyone run this up with a 700-68-1400kv on 8s. I have this fan with the motor and ran it up a couple days ago. It held together but I didn't get any numbers off of it.....it was hard to see from 40 feet

Thanks scunna this will help. Nice flight and it does sound good.

I have the DPS fan as well, well except for the rotor, HK forgot to ship it with the fan.

I plan on stuffing the DPS into a Sniper XL on 8s.

The CS is going in a Mig 15.

Sorry but that's not correct! I am using the Het Typhoon Brushless Motor 600-37-2 (kv 1700) and I see 87 amps and about 1800 watts on 6s. The actual kv could be lower than 1700 kv. I use 25 c zippys but with 65 c you may be >2000 watts.[/QUOTE]




Ummm ive got a het 600- 37 -2 sitting doing nothing its in a wemo shroud wonder if the 12 blade will fit in there ? them numbers sounds ok for a good 6s setup

Update on C.S. 12 blade 90mm. w/ARC 1400kv, 120A ESC,C.C.Pro BEC., NEW 8s(2x4s)40c-3700mah. Tested all equipment, out of airframe, everything works, and is in the right direction....LOL. Spooled up balanced fan on home-made test-stand. Runs smooth as silk. Do not have correct connectors(EC5s) on watt-meter to get actuals yet, So in the plane she went, while I wait on new connectors. Fan sounds sweet.....I upgraded all my plugs on this jet to the EC5s, but forgot about my test equipment.....DOH-H-H!!

Does this look right?
This is a glued CS12-90 on HET 700-60-935 on 12cell 3300 25C Genace. CC80HV and an intake lip modded from another fan. No exhaust ducting.

My thrust setup got 10lbs 7Oz. on the short runups I did.
