Computer Flight Simulators > XTR weathervaning?

1winder

Heliman - Location: Sayreville, NJ -

How do I stop the models from weathervaning in Reflex? I am trying to do some backwards flying and it is driving me crazy. I alread set the tail fin area to zero and have put the gyro settings all over the place. The tail is realitively locked in when doing flips and stuff, but when the airspeed raises it's all over. Has anyone been able to accomplish this?

Make sure the Piezo-Integral gyro is selected and you have you radio's end points adjusted for the appropriate gyro gain according to the Channel Display in XTR.

Some models I just plain can't eliminate weathervaning no matter what I do.

I really only use two heli models which both hold the tails really well for me. The Raptor V2 Tuning and Stouf's JK Fury. They hold so well that I have to use a lower gyro gain for a realistic hold.

I use the Fury for learning new tricks because it has the power to muscle through anything. Then I switch to the weaker Rappy to learn collective and cyclic management with the tricks.

I use the Piezo-Integral gyro, and as far as Reflex is concerned via the channel analyzer my end points are -100 & 100. I have tried adjusting the gain using the end points previously mentioned, and also in the parameters menu. Both methods seem to yield comparable results. After experimenting with the blade chord, tail rpm, blade length, etc, I have come to the conclusion that there is no way around the weathervaning effect! Apparently, due to the lack of responses, no one else has a solution either.

It's hard for me to believe this was over looked during the initial build process, subsequent testing, and in the ensuing updates, especially given the current popularity of 3D flying and the widespread use of heading hold gyros. Reflex would be nearly perfect in my eyes if not for this singular aspect. It clearly is a powerful tool and has helped me to improve my piloting abilities immensely.

Does this weathervaning effect anyone else or just me? If it is a common gripe amoung Reflexs proprietors, and we me make our suggestions known, maybe they will be willing to address it during the next update. This is not an issue in the older version of their competitors software, so it is likely not an issue in their new software either.

I am sorry to rasise such a fuss over this, but if the end result is a simulator that more closely approximates actual flight characteristics, everyone will benefit from the discussion. More importantly, Reflex will be able to say they have a superior product.

It's mainly why I just use those two specific models for aerobatics training. They do anything I want them to do.

Certain models I won't try certain tricks with because they just won't do it and I can't make them do it. Even though I mostly fly micro helis in the real world, I usually opt to use nitro helis in the sim because most micro models fly horribly in aerobatics.

I think it's really a result of amateur modelling where they just make them look good from pictures but don't have the patience resources or know-how to make them fly right.

It will be interesting to see if the W3Group will be able to produce realistic flying heli models from their philosophical approach.
(they did an interesting job with the mini edge 540 I have, I can't say it's exact as every real model flies different, but I am convinced that their's are probably the most realistic models I've used).

Basicly, what it comes down to for me is I don't want to switch back to G2 to learn backwards & backwards inverted flying. If anyone knows someone who may be able to address this issue could you make them aware of this post please.

Well there are models that will do anything you want. I named the two I use. Just have to find the ones that meet your needs.

I have no problems with this. You can fettle with the setting to make the tail hold better too. Captain Chaos you should try the Trex SE from RC Sim the tail holds great on it. Upping the tail rotor RPM usually helps a good bit. From there you can also turn down the response time and the servo travel speed. It shouldnt be hard to get the tail holding really well on all the 3d models!! Its just a set up issue not a XTR one. Play around and learn what the setting will do that all i did. Some of the values may not come out to 'real world' but as long as the model flies properly all is good!!

This Heli Will Self Destruct In Five Seconds!!

XTR

Got to physical parameters (Tail Roter)
Lower Gyro sensitivity alittle at a time
untill it stops wagging!
Worked for me.

He never said it was wagging...

Its blowing out during backwards flight.

Sorry Rick, just trying to help!
My tail don't blowout!

Tail blow-out is a normal function of helicopter flight that is VERY hard to compensate for even in a REAL helicopter. Try increasing the size of the width of the tail rotor blades. This helps on real model helicopters and should perform the same in Reflex.

It holds fine when flipping, hovering, etc, as Rick pointed out. My problem is with fast backwards or sideways fligh

I would be interested to hear what Jeff Green has to say about this, MRC does the importing right?

I'm curious which model you are using and having the problems with. Maybe some of us can try tweaking it with our individual methods and see if we get any favorable results.

I understand the desire to prevent blowout when trying to learn backwards flight. It's easier not having to try to counter blowout tendencies in the beginning.

I have the gyro switch set on my Tx, and I can switch between Heading Hold and Normal.
In normal rate the Heli will weathervane, and I adjust the amount of hold by setting the gain value on my JR X2610
Flicking the switch to Heading hold and the Tail locks into place.

Normally I fly th Evo 50, because I have one, but lately I've been using the Freya. I usually fly with a 1950 head speed. On rare occasions I'll use the V2 tunning Raptor.

I tried both those models and found that the Freya does weather-vane, but not severely. It does something else weird though, seems I could be cruising along in inverted backwards hurricanes and just move the collective stick further towards it's extreme deflection and the heli would snap roll or corkscrew to upright and still be travelling backwards. Really weird.

The Sceadu doesn't seem to weather-vane on the rudder axis for me at all, but it does weather-vane on the elevator axis really bad. That horizontal fin will catch an edge in the wind and flip the heli on a dime. The rest of the time it's just resisting against my elevator inputs.
