Ammo 36-56-1200 inrunner


Has any one experience with the ammo 36-56-1200 inrunner
I am wondering what size prop I would be able to turn with it on5 to 6s without a gear box.
It is rated for 1036 watts max around 50 amps
Thanks

Like most GreatPlanes estimates I reckon that rating is way more than the motor can manage.. 283g motor at 3W/g is 850W.... not 1036W.

MotorCalc indicates that an 8x6 might be possible on 5s:

Motor: Great Planes Ammo 36-56-1200 (#5310); 1200rpm/V; 1.2A no-load; 0.034 Ohms.
Battery: Thunder Power TP4400 (G4 ProPower 45C) (45C); 5 cells; 4400mAh @ 3.7V; 0.002 Ohms/cell.
Speed Control: Castle Creations Phoenix 60; 0.0012 Ohms; High rate.
Drive System: Direct; 8x6 (Pconst=1.17; Tconst=1) direct drive.
Airframe: Anything you want.

Motor Amps = 48.3
Motor Volts = 18.0
Input (W) = 867.0
Prop RPM = 19166
Thrust (oz) = 70.3
PSpd (mph) = 108.9

Thank You DR Kiwi !
I am considering using it in a giant prop in the slot pusher Jet.
The 8x6 would be a good fit.
Have a Great Holiday
God Bless our Veteran's !

You can run it at or above their specified rating, but you need to limit the time. Only a temperature reading will tell you how long it can handle it.
