Hello! I have New Power Modelisme Extra 330S ***********
Flying weight=1900-2000grams. Will be able to fly 3D on this plane with this motor? What has thrust this motor with 12.5x6.5 propeller?

I don't think you can fly 3d hovering with this motor and that prop for the extra.

If my plane have weight 1900-2000grams and this motor, what is propeller i need? i think that 13.5x4.5. I'm right?

if I will lighten the plane up to 1700 grams, will be able to fly 3D on this motor?
 whiskey29 127 points
I think you will better be with saito 72. Its lighter and you can definitely use 13.5x4.5. I am using it with 13x6, I don't fly 3D, but when it was new 10 years ago, it would pull my ugly stick vertical. You should go to youtube and search what people are using.
I saw the link you gave, the airplane looks to be lightly build.
How are you gonna save 200 grams ?

In user manual indicated weight 1900 gramms. I calculate weight: wing fuselage landing gear horns clewis motormount fuel tank cowl cockpit=11600gramms. This engine have weight 450 gramms. 5 Servos=78 gramms. RX RX battery=50 gramms. In the issue I have flight weight 1718 gramms without fuel.

Hello, You still got some prop, spinner,glueing (yes even epoxy would add a few grams), switch, servo extension cables, pushrod, wheels, and ballast if its too tail or nose heavy and if it can't be compensated by shifting things inside. Fuel will add significant weight. So the flying weight might come close to 1900gr. Any way, I really suggest you to have a look at saito. Its light and powerfull, and saito 82 is not even heavier than 72 but will give you oomph. While the asp fs 61, I can't weight mine, since its installed on a test mount. But it could be more than 450gr with the muffler.

I bought two of these engines , both started straight away and run perfect even down to a low idle using 10pcnt nitro - plenty of power using a
12 x 6 propeller and economical on fuel.
smooth transition from idle to full throttle.
i am very happy with the motors for the price.

This engine is out standing. It started on the first try, no problems. It was pre set from the factory so I didn't need to do a lot of adjusting to it. It's worth the money believe me.

Wow! super engine. I use mine in a 40 size low winged trainer. Plenty of power, easy to start and running clean. Would recomend this to anyone! Perfect to use later on a 40 size acro plane too. nice!

Great engine - very happy. Make sure you prime it until it is literally soaking in fuel and then it starts easier than any other engine I have come across. With a 500cc fuel tank I get around 15 minutes of mostly full throttle running a little on the rich side with a 11x7 prop.
