Question
TF8000 Bench Test Data?

Hi,

I would like to integrate the TF8000 in my Fan Calculator (http://www.s4a.ch/eflight/fancalc_e.htm). for that I need your help:

Who is currently running a TF8000?

I am interested in your data regarding:

- Setup used (Motor, ESC, Battery)
- Datas evaluated on the bench or in the airplane?
- max. Current
- Voltage
- resulting (static) Thrust
- if available Efflux
- if evaluated in the airplane: Exhaust pipe diameter/area
- approx. elevation above sea level and temperature at evaluation

thanks for your help!

Hi Markus,
have you already talked to Ueli Amacker or the Hotz brothers!?
They are using the NEU motor perhaps they have some datas for you.

I did this modification. The problem is I never got to fully test it before it was returned to the customer.

It showed great promise.

Ejets your fan calculator is a godsend. I use it daily(seriously).

That being said, I've found the ds-30 model to underrate by a few amps and watts when using higher powered setups. In some cases as much as 15amps and 3-400watts. I can provide limited data on running the ds-30 to around 3000-3500 watts if you would like to increase accuracy.
