Took the ARX out today, got to say I am very dissapointed with this bike, not even one run before the gyro gave up on me and started howeling, tried to keep running it but I gave up. The steering just seems to flop over from one side to the other even with the springs backed off as far as they can go they seem too tight but think if you had them any softer it would not turn, steel crashbars worn away after very little run time, really dont know where I should go from here, I was expecting great things from this bike, here are a few pics of the gyro after I had got the tire off and got it apart again its just a real mess in there.

No I have that bearing it came out on the shaft and I took it off for the pics, it looks like all the clutch assembly is trying to push its way forward into the flywheel and it all binds up as there is only that thin disc to hold it all on, plus is it right that one side of the wheel shaft sticks out more than the other, I mean the locknut on one side only goes on half way to the swinging arm and the other side the lock nut goes on all the way to the nylon part of the nut as it should, what it needs is a C clip to hold that thin plastic disc on that holds the clutch shoes in place, but that would make the shaft even shorter. I have asked on your site about the electric gyro, thinking of making it speed up and slow down like the Kyosho.

hi friend

I have to put 2 or 4 gear on the item:
X-032?
In item X-032 having 4 axes where one puts gear gyro. Which is correct? Second or fourth gear. What should I do?
Put grease on the gears?
I bought the ARX-540 nitro pro kit.
thank you

Hi, the pro kit should have 4 gears like this, & no grease on the gears leave them dry.

This is spooky! Even in reverse!

I have found out that the nylon part has come away from the steel flywheel it was lose, I took it apart and found there were 3 holes drilled in the nylon as though pins once went in there to stop this happening. I have drilled through the steel ring so they line up with the holes in the nylon centre and screwed it on with 3mm screws, then clocked up the flywheel and trued up the bores and sleeved them to get the gyro running true, still got lots of end float and shaft sticks out one side more that the other, taking it to work for another look.

It should have had screws in it Steve my old one has, & the shaft should not be sticking out further one side, here is a pic of my old one, do you have the right spacers fitted? you should have a 7.5mm spacer on the gear side & on the other side it say's in the manual to use a 4mm spacer but on mine they have added another c-clip to to the shaft 2mm from the first c-clip & then have used a 2mm spacer instead, i also had to shim between the flywheel & first c-clip to stop side play in the flywheel.

The holes were there for the old gyro weight, which was lighter.
The newer one is machined, heavier and press-fitted to the nylon part.

I have both on the eGyro, and use them as setup options.

Throttlejunkie thanks, been out with the bike today and apart from very poor range from the Fly Sky FS-GT3B radio it ran ok, Still cant get the steering right, Im sure the steering springs are too strong, they are the new progressive type but it just seems to flop the bike down on the bars no matter how carefull you are. The gyro seems to be running free as you can hear it spinning long after the wheel has stopped so thats one job done and I made some spacers to get the same amount of axle length each side.

Steve, Have you tried setting the EPA of the steering down? You only need enough travel in the servo to move the forks to the mechanical stops or even less on some set ups. Maybe a little expo too if needed if the springs are the problem. (seems like the progressive springs should have a similar effect as the expo, unless they are too stiff on the soft end too.) Just trying to help!

Top Dave I have knocked the EPA down to 45% but still slams it down hard, sure its those springs or the strange steering set up, sure this bike would be better with a standard front end like the Anderson and not the Ricky set up, its all so stiff it cant self centre, will ball race the whole lot and see what happens.
