Guys:
Just put a new Fury Expert YS61 into the air this weekend!
Thanks Scott!
Twice this afternoon while approaching nose in from
the north, light winds, Futaba 9CHP, Hitec sup8 ppm, 9252's,
tx batt = 11.2V, rx volts was 5.2 at lift off. 3 Minutes into it
the machine popped out of control for a half a second!
I had the antenna pointed
directly AT the machine at the time. I have a revolution
base loaded rx ant on the starboard side Landing gear
braces (Parallel with the skids.).
After it did it the second time I immediately landed and
thought that the knowledge base here on RR might be
able to assist the resolution of this dilemma!
Scarred the heck out of me!
Any thoughts?
Me: Reorient the BL ant. (I do have 7 inches of wire rather
than the 4" recommended, but have never had a problem
like this on my 9 other heli's!)
Crystal is new and taped down in place. RX is in foam
directly above the battery on the front servo tray.
Shoot me some ideas.
Byron

All I can think is the rx ant. Unless the heli is getting some metal to metal noise that is freeking it out.

Good Luck, those are the tough ones to figure out.

If i were you i would get a PCM reciever such as a Futaba 149dp because FM is prone to glitching from what i hear on fury's from all the moving parts.

the area of weakest signal propagation is out the end of the antenna. it is considered best to not ever point the antena at the heli for this reason. sometimes we get away with it. but with that crap hi tec rx and a crap base load antenna, you arn't going to get away with it for long on this heli.

helicopter,

Where do you fly in Omaha? I'll be there on the 10th of this month. I may get some time to come watch, I don't think my wife will let me bring my helis though

I'll be in South Omaha just off of 75 I think. I have some relatives there.

Thanks to RR I found the reason my Fury was going into fail safe every so often. The battery shelf is held to the frame by a round headed screw that is located directly below the battery. Check to be sure the head of this screw has not rubbed itself through the battery shrink wrap leaving you with a metal to metal glitch travelling directly to the switch harness. My glitches were sporadic and only seemed to happen when the heli was at the same attitude and position as related to the TX antenna. Good luck!

Didn't the transmitter come with a PCM receiver? Throttle fails safe to idle is mandatory in my book. Yeah, yeah here come the flames.

I'd follow the instructions on the leader length to the Revo antenna. We use these without having any problems. Also make sure the connector isn't making intermittent contact. Most guys just solder the wire.

you should keep your antenne as horizontal as possible, never point it directly at the heli

when you drive rc cars the antenne is best vertically

another point is the antenne, i bet your antenne is fixed on your skids an is pointing horizontal to the tailboom

let us now something

Thanks Gents!

Too busy the last coupla daze to look at
the FURY I took a bit of advice from both
Mongo and the former owner and ordered
a FUTABA 149DP receiver and new Fxtal.

I have had great success with the revo and deans
BL antenna's on a bunch of other machines!
But I just may utilize the one meter on this one!
Scott won't mind, but Mongo, since there is only
one of thee, don't punk when I say the prob is
solved over the coming weekend!!! :-)
Chill!

Thanks fellas! Got some great ideas to follow thru!

Switching to a PCM receiver will no stop glitching. It will hide the small locks you are seeing, until you get the big one!! I would try to find out where it's coming from first before installing that new receiver. Could be bad antenna wire, bad crystal, dry bearings, any number if things.

Thanks Allen!

I see that you are RIGHT!
I am going to move the antenna to the underside of
the tank, and off the skids. Then Follow their directions
and cut the wire back to 4" instead of the 7" I now have!
The machine has 2 gallons thru it from the former owner
and he never had a glitch with his deans ant and PCM
receiver!
Thanks!

i am always glad to see folks get away from cheep equipment in expensive helis. but i really think yer problem is a combo of pointing the tx antenna at the heli, and the base load antenna. change either of those and the problem will most likely not recur.

Issue Resolved!

Dudes and dudettes:
I installed the futty PCM rx in her today.
Took a careful football field range check,
then went way high. No problemo!

All is very well.

I did eliminate the Revolution Base Load antenna on
this particular machine and installed the one meter
standard futty wire whip.

(New F 149DP PCM rx with new xtal.) 157.90 servocity.

Thanks for all your advise!

This is a very nice machine!!!!!!!!!!!!!!

Oh and the gent coming to Omaha on the tenth,
a wednesday, give me a return email and I will contact you!
