I use REFLEX as a trainer for mastering helis flying. Currently I am at the elevator / airelon hover trining level. I found difficalt to keep the heli solid stable in the air. I can keep in in the air but I need a lot of space for hovering. Is it just a matter of training to keep in level and stable or I miss something?

George,

What heli are you using? I don't have REFLEX I use G-3 and I'm new and had the hardest time getting any of the models to solid hover. With hours of practice I've discovered the larger models really are more stable than others.

Do you have a setting for expo ir dual rates? Best of luck..

I use TREX and I do not use expo or dual rates.

Picking on of the scale models helps in G3

I use the EZFly Trex450 and Bob's (Finless), which is very similar. The hovering trainer seems harder than just slowly lifting off and trying to keep it in one spot.
Anyhow, here's the secret! the instant the heli starts to drift off, input a TINY amont of cyclic correction and hold it for a second, then just before the heli visibly responds to your correction, remove it and give an even smaller amount of opposite cyclic. What your needing to do is kill the tendancy for the heli to build up any unwanted motion, before it gets properly underway. If you wait until the heli is scooting sideways then input a big handfull of cyclic correction, it will start a motion toward the other direction and before you know it your fighting a pendulum effect that just gets inreasingly worse until it crashes. Its all to do with the delay in response and timing the corrective input. Another tip: watch the main shaft for tilt, it gives you an instant visual feedback of whats just about to happen.
If your still confused think of it like this - remember when you were a kid on a swing seat - the legs going in and out to keep it swinging, yes? Well remember how odd it felt deliberately swinging your legs out of timing with the swing to get it to slow down - well thats the effect your aiming for in hover, small movements of cyclic that kill off the swinging pendulum effect by using appropriate timing.

nice explanation Rick

The Ezfly t-rex is pretty dire, though. I much prefer the newer SE and XL CDE versions from rcsim.de.

mmm i seem to be able to hover a Raptor 50 v2 tuning (i think its a titan) pretty solidly, with a little wobble, and ive never flown an rc helicopter in my life, its just practise!!!!
