I got it done But Still waiting on the Bobcats to get back in-stock
Has anyone tried the Jetfan90 rotor in a HET fan shroud? I have a Jetfan on the way to me but I built the nacelle for a HET fan because of the inlet ring.
What is the best kv for a 10s setup with this fan? I was thinking 1400kv or 1200kv? Thanks Billy D

The HET inlet ring fits good on the Jetfan90!
Only the HET shroud is longer than Wemo or Jetfan housing.

Looks good BILLYDSRC!

Spyda use a single outlet, seal the outlet tube to the housing with tape, make sure your motor shaft is running true, make sure you have not collected dirt on the back of the fan blades, use a quality ESC, soft mount the fan housing. If you've done all that and you are still not happy then spend another 370 plus motor on one of Stu's fans. The jetfan is what it is, a good performing fan, a sweet running fan, a much better sounding unit than a wemo or het at a reasonable price.

Hey Air...what motor did your buddie use? I need to order a motor that will work on 8s and this fan. I'm new to jets and what the perfect motor that will also fit the fan perfectly.

Better results with better materials! JETFAN-90-V2!

Hi Caps,

maybe you didn't hear so much from us the last weeks, but we have been very busy testing new materials for our fans.
So we tested several stiffer materials for the rotor, as also we investigated in a newer design of the inner stator.

Together we reached a better performance at the tested motors! Here you can see the old charts, with the V2-tests added!

All grey motors do show in the first line the old results and in the second line the newest ones.
Also a commend to the motors is added.

So also the last deliveries to you do already have the new stator and new material for the rotor.

There's no need to cry about " i just ordered and got the old one ".
Pending on the time of ordering, all the last deliveries have been sent already as the V2!

Here are the results, but we couldnt test every motor again. Some of the Tenshocks are working together with our V2 better and healthy now, they are running cooler and at a higher efficiency.

Seems that with the newer and stiffer material of the rotor blades, the tip of the blade is now less twisting at higher rpm's. As our blades are sickled forward, the tip will twist to a higher angle of attack, and the load at the blade is not as calculated! Now it seems that we are reaching absolutely less twisting and a aerodynamic load very near to the calculated basics.

And the best: All new test show again less temperature at the motors!
So also cheaper samples could be used now, see the XK 4074-B 2000KV at the 6s chart!

Have fun with the new "better results"
