Prop for OS 91 Surpass on Escapade 60


Hi, I new to airplanes and was wondering what the best prop for an OS 91 FS Surpass would be? I have a Super Tigre 51 on my Eagle 2 trainer with a 12x5 prop and I can make it climb staight up in the air from almost a dead stall. NICE! Lots of power for this 40 size trainer. I recently bought an Escapade 60 with a OS 91 FS Surpass and It doesn't have the power to climb staight up in the air like my trainer can. I have a 14x6 prop on it now. Do I have the wrong prop or is the bird underpowered with a 91? ........or should this heli guy(just converted to planes) stop flying his planes like helis Thanks in advance for the help

Try a 13x6 or 13x8

you can realistically fly the Eagle 2 with a .25. so power to weight wise you are not as overpowered with the Escapade as you were with the Eagle. that being said, if you want it to pull unlimited vertical you should probably go for something like a 91 2 stroke glow or a 20cc gas.

I would go with a 14x6 for good performance. I have a Fox .74 Eagle IV in my Escapade 60 and it has good performance. On my Revolver 70 I have a Magnum 91 four stroke and it flies great.

I fly a Pulse XT60 with an ASP 0.91, fitted with a 13x8 Evolution prop.
Most of the time I cruise on 50% throttle, if I go vertical and open full throttle it can climb straight up.

I fly my Escapade with a ASP 91, Master Airscrew 13 x 10 S2 series prop, no problem going vertical. Just be careful of weak elevators on these planes
