I has to make new rewiew on the Rotomax 1.40
Motor : Rotomax 1.40
Battery : 10 S 5000 / 25
Regulator : Turnigy Super Brain 100A
Propel : Aerospace wood 20 x 8 6500 rpm both optical and ind the ESC
This set up:
Pull's 8,1 kg
RPM 6500
Amp 61 battery drop to 37 Volts = 2257 Wats = 3.0 HP
The ECS is on timing high an 12 MZH brake off,
It is not quite right that the numbers of poles is 24, like written in the Discription. If using 24 poles in the ESC for measurement calculation of the RPM, you willg get wrong result.
It has been more correct to write in the description :
stator poles 24 and magnet poles 28, it is the magnet poles thats count when calculeting RPM,
So if using the Super Brain PC progran, set poles count to 28 for the RPM calculation.

Aprs 10 vols sur un avion maquette de 8 kgrs ce moteur est parfait. Fonctionnement trs silencieux et absence de vibration.
Configuration APC 19*10 10S 5000mAh Env 30 A Puissance env. 1100 W. Une 20*11 serait donc parfaite pour atteindre 2000W pour des vols plus acrobatiques.

After 10 flights this motor run perfectly and whitout any disturbing noise.
Light configuration : APC 19*10, 10S 5000 mAh, Current 30 A, Power roughly 1100 W. This is enough for realistic flight on a 8 kgrs airplane but not for extrem aerobatics
For more aerobatics a 21*11 Propeller should be better.

A few weeks ago I bought this engine Along with turnigy dlux 160A After assembly and testing it is squeaking sound.
I tried all the options of the esc has not worked until I changed the Castle Creations 120A
Now works great I do not recommend to combine this engine with this esc because it does not fit.

Test on the ground. Rotomax 1.40, Popeller 18 x 10. The TURNIGY K-Force 120A-HV OPTO, and 2 x 5S Zippy 4000 Compact 25C, measured 45 Amps and 1550 watts. The Rotomax makes a good impression.

im going too buy this one as a replacment for my KD6328s but im not sure as too why when 2- 5s packs are series up it puts out over 40volts but here it says max 37volts on 10s how does that work?
reason for this one is ive gone up from the MAS 16x10 - 3bladed prop too a biela 18x10 - 3bladed im hoping this motor will spin it as the KD smoked up anyone have any suggestion on my combo?
