Hello all you pro guys,

I have this UCD60 and i'm running a OS91 FX engine. with a APC 16*4 wide prop.
Can anyone please tell me if this the right prop for this engine? If it is so then what is the rpm i should expect out of this combo.
I'm right now getting 9700 with 20% fuel. Some one was telling me that i should expect 11000 rpm with the above combo.

I also have a Katana profile 3d for a 46, i'm flying it with a os55 ax enigne with a 12.25 * 3.74 prop, is this the right prop for this? also what is the rpm i should expect out of this? i fly with 20% fuel.

I'm flying since 12 years or so, but no serious 3d flying. I just started to learn hovering, but not able to, so the best to blame the equipment

I'm trying to learn hovering, also would appreciate if any other tips to learn this, yes i practice in the sim, in G4 and i'm able to hover the yak (without the gyro) very well.

What expo should i dial in on the ail, rud & elev? I'm presently in 30%.

Any tips is welcome.

Thanks & Regards,
Adarsh
