I have a lot of trouble flying backwards. Not because of orientation, but fighting to keep the tail where i want it. i raise the headspeed and gain as high as i can before she wags. I use fins with a low surface area and all that good stuff. But the tail always drifts and i cant fly backwards nearly as fast as most other people i have seen.
I'm wondering if their machines actually do the same thing but they compensate for it or just let the gyro take care of it to keep the heli straight.

are you using a heading hold gyro?? im not an expert but using a heading hold gyro should help..

Deadstick: Two of these can be found on a transmitter that has been inproperly charged.

Well, I tried a Vigor/YS91/601 combo this past weekend and the tail was locked in SOLID, like it was in a vice grip. Not only that but the tail stops with a "BANG" as soon as you let go the rudder stick. One word, AWESOME. The Vigor is a very impressive ship and the 601 absolutely rocks! Don't know what gyro you are using but if it's a 601 you may have some setup issues. My Evo/401 combo tail performance is no where near the level of that Vigor I flew.

401/9254 is the ticket!

Hi Furious,

I fought with this alot on my Raptors. My Gyro and tail were great until I really started flying backwards. I really found that I had to rework the linkage for max throws, use 92mm tail blades (Freya tail blades are my favorite), up the head speed, and lube the tail linkage until it was as smooth as glass. I got much better performance out of it in backwards flight.

Even after all was said and done I could still be hauling a$$ backwards and the tail would start to lose it. If I slammed more rudder to it I could force it back inline. This lead me to believe that the 401 would not put all the available throw into the tail if the situation required it in order to maintain heading.

The solution is to go to a 601 gyro. A 601 will slam all it's got into the tail if need arises to order keep it on heading.

Good luck.

It sure would be nice if some shops would get some more 601's in. I've got 3 heli's I need them for and after using the 601 I really don't want to use anything else. I'm just starting to get into backwards flight on the sim.

GY-611 will be the replacement. Wonder what is different and when it's coming. After trying the 601, I know I need one! Question is buy the 601 now or wait for the 611.

What I'm hoping is the 611 lowers the cost of the 601. The 601 is all I'll ever need.

Somehow I don't think that will happen. Just look at the "next 9z", the14MZ radio price.

Sorry, i should have stated this at the beginning.

I have a Vigor with a G5000T gyro with the 8700 servo, and running a YS80 with MP2.
I'm thinking that maybe there is too much resistance on the linkages, even though i lube them with white lithium greese after every other flight, it remains pretty stiff. i'm thinking this could be part of my problem because the servo has to work that much harder. i'm using the stock carbon rods right now. but when the so called Vibe comes out in mass production i'll use the upgraded control rods from it (supposed to solve the problems with the older rod).

Scott Gray already has somthing like that on his Vigor's, but i dont want to move my tail servo to the rear of the frame, i just dont like the look of it. although i have to draw the line between having a sweet flying heli, or a sweet lookin heli.

I remember people saying that about 401 gyros and 386 computers with 4 meg of ram.

What gets me is why they feel the need to come out with a new model when the 601 is already the best gyro going.

My two cents..

Not to rain on anyones cornflakes, but all my Raptors do very well with 401/9253/4....Stock tail blades, 1750/1800 headspeed...I own a 601, and like it, but it's not necessary for bacwards flight...

I am also in backwards flight...not extremely fast but moving along pretty good. Using a 401/9253 it seems to hold, but wags sometimes coming backwards out of stall turns etc.

I have a JR 5000T/8700G that I have never used. My question is, will the 5000T hold better than the 601? I know the JR/Futaba ramblings...but setting that aside...how does the 5000T handle in fast backwards. I just dont want to break down and spend 300+ on a better gyro when the 5000T will work.

Dont know the severity of the binding and I'm not saying this is the problem but around these times when the weather is cold, white lithium grease has a tendancy to gum up and bind things...

I have stopped flying for the winter weather is near, therefore the white lithium gumming up in cold temps is of no concern. i also know that Scott Gray uses, or atleast did use the G5000T and does insane stunt and backwards flight........but.....he has also been able to do backwards hi speed flight WITHOUT heading hold on. which is why i was aksing if its the gyro or the pilot that keeps the tail straight at high speeds. i have heard the G500T is somewhat better then the G5000T, but at my level i wont likely notice it.

Furious,
If you have too much resistance on the pushrod, I would consider greatly to go with the aft mounted servo setup. I also heard many times that no JR gyro was worth the container it was shipped on, until the 500T came along.

Moneypit,

Thanks, that says alot...I'll try the 5000T, but if it doesn't work out...I'll put it in a scaler
