I would like to see more testing on that rotor. That thing was screaming. I Know when I was sanding out the motor tube on the 90mm I noticed little white flecks in the plastic like it didn't get mixed good. It would be nice to see them change to a better mix so they will stay together.

I think 6.5lbs of thrust for this rotor is really reasonable and prolly it's peak again motor must have heat and good airflow to last
Would have to agree, all the fanboys aside (pardon the pun ) there are plenty of people testing these fans with many different setups, serial posters or not LOL (and no am not labelling you a serial poster!)

No, I am not a shill. I just think it's only reasonable to pay for your R & D costs.
Thats all well and good, but when I did the initial testing and put out a couple of pretty reasonably priced setups with alloy shrouds, custom adapters and spinners, I was attacked for wanting my R&D costs back, one of the principle attackers being someone who now works for TJ.

Let's read some test reports and see some videos of your tests.

You will have to go back lots of pages but they are all there, and the test figures are all up on the website on each combo listing. Plus there are plenty of them being used by flyers now, in OZ, US and EU.

I have about ten flights on my new cs70mm combo now in my foam habu. Previously tried these 4s combos ... fsd 2881kv innrunner (smoked after 2:20), suxfly 2950kv innrunner (smoked after about 20 seconds), 2850kv outrunner from fanjets (works well but the motor itself is a little out of balance - just under 1100 watts)


new combo...velocity 2900kv motor / cs rotor / E-Flite shroud / tj adapter / tj spinner washer / thunderpower 4s 65c 3850's...seeing 1300 watts at 87amps right off the charger. settles to just under 80 amp after maybe 15 seconds. great power, smooth running, great sound ... shorter flights

Try BL32 2150KV motor.
6s 1800watts.
That Sean flew his foam with until his old man put 7s and blew the rotor.
He is not even mad at all. He want to goes fast too.

So how is 2300W/96 Amps suddenly an efficient lightweight 70mm setup? at only 43K rpm? I see 40K rpm at just over 1500w with a 2W30. My F16 is doing around 130mph at 33K rpm and 860W.

How is it the MEGA motors are rubbish but the eflite motor is suddenly the best thing since sliced bread? The amount of spin in here is incredible...

Hang on, wasnt this figure at 41-42K rpm?
And the new figures are 2300W/96A at 43,200rpm.
So your setup needs another 500w to get that extra 1000+rpm...
