Once you've decided on a suitable motor / powertrain setup that is capable of delivering the required wattage, then play around with propeller selection. Realistically it all comes down to experimentation as far as actual performance goes. 180 to 200+W/lb - faster jets and anything that requires cloud-punching power!īy working around those categories you should be able to decide how much power your rc airplane needs to perform well The categories aren't meant to be exact, but they are very good starting points.120 to 180W/lb - more serious aerobatics, pattern flying, 3D and scale EDF jets.Many scale ( eg warbirds) planes suit this power band. 80 to 120 W/lb - general sport flying and basic/intermediate aerobatics.50 to 80 W/lb - light powered gliders, basic park flyers and trainers, classic biplanes and vintage ('Old Timer') type planes.Less than 50W/lb - very lightweight / low wing loading slow flyer.

Here are some Watts per pound values that should put you in the right ballpark for your particular plane. Both biplanes, but at opposite ends of the Watts Per Pound scale! General Power Guidelines At the other end of the scale, a powertrain setup that's delivering 200 or more Watts per pound is going to have pretty much unlimited ballistic performance!Ībove: A WWI SE5A, left, and a modern Pitts Python. It's generally accepted that any plane with less than 50W/lb is going to struggle unless it has a very low wing loading.

The rule relates to how many Watts (W) of power are needed per pound (lb) of airplane, and the approximate values range from 50W to 200+W.

More of a 'rule of thumb' than set in stone, the Watts Per Pound rule is one that lets you determine the power output needed for your electric rc airplane, to give it the performance that you desire. They have also changed to hard ply as well.Ĭ.Home Site search Site Map About Me Contact Me Site FAQ Privacy/Cookie Info Testimonials **Recommend by the factory that the center wing spar is glued to the center wing tightly** Also, newer models Sept 2021 and later the center wing has been reinforced with carbon sheets on both side of the main spar area.
