Macht erstmal einen wertigen Eindruck

Oct 10, 2019

Vor dem Einbau wurde ein Leistungstest vorgenommen an einer 3-Blatt Luftschraube 11 x 7.
Ergebnis:
4S-Akku 7.800 rms 18 A
5S-Akku 9.500 rms 26 A
6S-Akku 11.700 rms 40 A
Bleibt zu hoffen dass die Qualität stimmt

F3A motor for 1.1kg model

Jun 11, 2019

I use it on a 110x110cm - 1.1kg model
with 4s4000mAh or 4s3300mAh, and APC 12x10, 8200 rpm .
F3A vertical climb on 60% of gas.
APC 12x12 it's too much
.
I use www.ecalc.ch.

Good motor but too short shaft

Dec 09, 2016

Yes too short shaft is a problem if you want to use for instance 13x6 3 blade propeller. To overcome problem I bought from Varioprop / Germany Collet Chuck Long size 12C and there is no problem anymore.
HK should really pay attention to this problem and have their Collet Chuck Long available so a lot of customers would be happy.

I don´t know if it is this motor but I am using it in a glider with a 14 x 8 fold with 4S 5000 and I only get 2.300g thrust I was expecting arround 3.000 Kg thrust


Could you reccomend me a motor with 3.000g thrust with no more than 195g weight
