Ian Turner has developed a really interesting idea here. I'm building one for trying out my first 450 size heli.

I'll let you know how I get on.

Ian is a very helpful chap and gave me a GREAT deal on my 2nd hand Blade 400 3D, worth a good look through his website!

Yikes I don't know man, it seems like there are a lot of things that could go wrong with that rig. I'm actually surprised being tethered down like that didn't confuse the gyro.

Obviously you can do anything you want, but with your experience on the mCP X, I doubt you would even need standard training gear for long, if at all. I know it's more intimidating because it's bigger, but I think you'll find it's actually more stable and easier to fly because of its size. You may even find the cyclic response feels a little sluggish compared to the mCP X's ultra-crisp response.

Either way, I'm tentatively interested in your progress. Good luck! Very Happy

Hi there

As the designer of the Hover-EZE rig I thought I should pop up here Wink

The rig certainly does not confuse the gyro, unless you try to force the heli to make turns with the rudder, which is not what the rig is designed for at all. The point is to let the heli stay tail in, and just to allow the new pilot to get the hang of the cyclic without the heli disappearing off into the distance, and probably crashing.

Because you can recover to a stable position by landing or going up to the maximum the lines will allow, you have 2 recovery modes, and most new pilots I have trained with it go up rather than down.

It is not a perfect training rig by any means, but I have used it now to train about 15 new pilots with 100% success rates, many with only one days extensive practice with me standing alongside them.

Just thought I would have my say Very Happy

I know what you mean Nick but I'm going to try the rig just to give me some extra security. The videos of people using them are pretty darned convincing.

By the way, I had a full look though the Chopper Addict site last night...WOW! Ian, you have put a LOT of work into all the guides you offer...you are a seriously passionate...well...chopper addict!

You chaps REALLY should check it out.

Were you demonstrating safety features of the training unit in the event the student looses control. What I saw is that the taught lines prevented any mishap regardless of the pilots inability to control the heli. I then assume the ideal position of the heli is low enough where the student is actually controlling the heli with the lines being loose enough where it does not prevent the heli from responding to the student's input. If so, then there is a merit to the unit.

I once built a similar unit, but much smaller, on approximately 1m square ply -wood to fly my first 4 ch flybarless Golden Contra. What I found that if my lines were long enough and the heli was only half way up and spun, the lines twisted together, became one single strand and I'd loose control. It seems though that your lines are not loose enough to do that. By the way, I know a Canadian real pilot who taught himself how to fly a full scale Huey using the same method using heavy chains and anchored in concrete. He is still flying the last I heard.

As you have very rightly identified Wink The trick when using the rig as you progress is to keep the tethers loose so that the pilot is in full charge of the helicopters cyclic control, as well as the throttle/pitch.

Once a new pilot has had a go on the rig, I normally move two of the tent pegs inwards about 3-4 inches only. This gives them a quite surprising increase in the amount of "free flight" they have available, while still stopping ther heli from disappearing off in any direction as it would usually with a new pilot. The tethers are also long enough to avoid the problem of allowing the pilot to wind them up using the rudder, (unless very determined to try to do so)

The other important part is the rubber bungee section of each tether, which stops any hard tugs on the helis skids or wherever it is attached to.

A final thought on Hover-EZE is that even experienced pilots can take advantage of it when learning nose in, when it is quite likely that the heli will try to go off somewhere at high speed after an incorreect input from the pilot. ?
