Hi again,
I would like to know if there is any sites with some examples of what settings to use on a slope plane? I want to get a better roll rate, realistic turns and more options from from my PC-9 and Futaba 6X Radio.
Regards,
Nigel Ball.

Nige I think this depends totally on the plane. There isn't a standard to go by. What plane are you referring to?

I dunno Nigel - are there any RCG threads, or a manual describing the throws?
The good thing is as long as the CG's right it's gonna fly, so if there isn't any info, just get it in the air and tweak it from there.
Sean might like to add, but I'd probably start with the aileron up throws at about 25 degrees and down at 15 degrees. Elevator 20 degrees up and down.
Firstly get the radio with all the servo parameters normal (centred at zero, 100% travel), no mixing or rates etc and mechanically tweak the linkages, clevises etc to get the control surfaces close to centred. Then set each servo travel individually in the Tx to get the travels about 20% bigger than the desired travels. Use a ruler to measure to ensure each aileron has exactly the same up and down throws. Always measure at the TE of the aileron just in line with the control horn. Then use the mixer/ rate functions to cut it back to where you want them (that way you have leeway to increase them later if you want).

Thanks Andrew. It does fly ok and I will have to do the measuring trick to fine tune. I get a little lazy so I do appreciate your help.

nige, i had a similar plane.. the CS AerMacchi.
i found the plane needed exceptionally strong lift and a constant solid breeze around 15kts.
roll rate wasn't particulary impressive, but at high speed it wasn't too bad. low speed i could barly roll the plane.
i had to add a chunk of lead at CG. by chunk i'm talking a block about 10cm long by 6mm thick by 15mm wide. this enabled the plane to penetrate the wind better and get more speed.
as for throws. i have duel rates on my controller. one set i would have total maximum servo movement, the other i would set it to 1/2 of maximum.
hope this is the information your looking for.

Thanks for the reply Jase.
I was thinking more along the lines of flaperons V ailerons and what chanels the servos were on.
The plane is working well but I wanted to eliminate the corkscrewing while doing rolls and generally fine tune it.
Regards,
Nigel

i had the corkscrew effect also... especially on slow rolls... i think the trick is to encorporate a rudder and learn to use that. or use your elevator as you turn.
either way i think it's the physical size of the fuselage which causes a lot of drag through the air especially being that there isnt' a motor to pull the plane along.

I have since added a rudder and I will be experimenting with that so I will see, thanks
