Helicopter control trim

[rocky289]

Now I have my flight controls sorted, I have been puting in a few hours in the Jet Ranger. I have even managed a few sucessful landings.
Flying in a straight line it gets a lean to the right. I am assuming there is no way to trim these craft like the fixed wing.

have a look here
I havent tried it myself but sounds like it should work..

Thanks for that.
It certainly does work. However the torque/rudder axis didn't work straight off. This was the very one I needed of cause. Fortunately there was reference to it in the readme & I was able to enable it. I have only used it with the Jet Ranger so far but it works exactly the same as fixed wing & defaults to the same key combinations.

Just thought I'd crank this up again.
Was wondering if it was just me that was having this problem with the Jetranger needing triming to make it fly in a straight line.
If so would there be a file somewhere that needs altering.
All the fixed wing models I have flown seem to track ok.

Good to hear that it works.

I can't really help you with the default Jetranger as I have the Dodosim Jetranger and that is all I tend to fly.
But if I get a chance I'll try it out

Anyone else having this problem.
When flying level 100-120 kts I have to trim 26% right yaw to stay level.
Then when I slow down or want to land the trim has to be zero'd

This is not a problem, it is an accurate representation of the real thing. In the hover the tail rotor supplys all the counteracting force of the main rotor. In forward flight the vertical fin is canted so that it takes over from the tail rotor (many helicopters can maintain straight forward flight with no tail rotor at all) So between hover and cruising speed the pedals must be moved to balance the helicopter as the tail rotor unloads, this process of course reverses as you slow back down to a hover. Helicopters do not usually have trims (there are exceptions for the cyclic in helicopters which do use hydraulics) because the pedals will be either hydraulic or weighted for forward flight, and usually they are not heavy controls in any case and this is not a problem.

For flight simmers constantly having to hold pressure via a twist grip this is a problem. Unfortunatly there is no easy fix. As you say if you trim for forward flight it will be out of trim in the hover. All I can suggest is trim for forward flight which is where you will be spending most of you time and then enjoy the accuracy of having to hold in pressure on the pedals in the hover.

I had come to that conclusion but needed someone else to confirm it. Must be a pain to to fly one with just a keyboard.

I'm a helo freak as well, do what I did and wished I hand'nt procrastinated for so long and buy a pair of rudder pedals and you will never look back. Take your time and you wil find a pair on trademe soon enough. Also awsome for fixed wing flying/taxing etc. Trust me you will be glad you did. Variable brakes aswell.
