Hi all,

Here's my plane's configuration (all is brand new equipment):

Funtana
OS 46AX
4 x JR 537 servos (2 x Ail, 1 x Elev, 1 x Throttle)
1 x JR DS811 servo (Rudder)
JR R700 receiver
JR XP8103H heli radio
JR Extra battery packs (either 4.8v 1100mAh or 6v 1100mAh)

I finished building my Funtana 4 weeks ago and have been trying to fly it ever since. So far, I have not even taxi'd it out onto the field and it has all to do with radio problems.

When I switch the plane on at the field I get incredible flutter off the ailerons and elevator. When I switch the plane on at home, I don't get any flutter at all.

After my first trip to the field, I went back to the hobby store to complain. They told me they suspected the 537 servos, that they would replace them, and I should try again. I did this. Didn't help.

Next I had a couple of the instructors at the field look over the plane. They suspected that the wires were crossed over and causing interference. We changed the wiring, hung the receiver's antenna away from everything. No luck. They suspected receiver.

I went and bought a new R700 receiver. Installed it in the plane and took it back to the field. No help.

I went back to the hobby store. Explained the configuration again, including the fact that the servos (all except the throttle) are on extension leads. They suspected that the voltage was not sufficient for the plane (I was running on 4.8v). "Get a battery pack with higher voltage." $35 for a new battery pack. No luck. Flutters like hell at the field. Nothing at home.

When I say "nothing at home," I mean that there is not even a buzz coming from the plane. Not a sound. Responds to all controls, even if I go stand outside and try and control it.

I don't know what to think anymore. I'm at a total loss.

I should also note that I have three other planes and a heli all flying off this radio. I have no buzzing on any of the other aircraft. The three planes all have R700 receivers and the heli has a JR NER 649S SPCM receiver in it. None of these have a problem at the field.

What I have noticed is that at the field, if I leave the plane on for a while (4 or 5 minutes) the flutter seems to lessen, almost to the point that it stops. At this point, if I apply any pressure to the control surfaces, it will flutter briefly and then settle.

I have tried this with fully charged batteries and batteries that are somewhere between full and half (I have a voltwatch in the plane to check this).

The aileron servos have 12" servo extension cables on them and the elevator has an 18" extension. The rudder has a 12 and a 6.

The only thing that I am left thinking is that the cold weather has something to do with this. At the field the temperature has fluctuated between 4F and 20F during the time that I have been trying to do this. I know... it's been bitterly cold. I have not had the pleasure of a day where the weather got above 20 in goodness knows how long.

At home the temperature is somewhere between 65 and 70F inside.

I have a theory that the cold weather outdoors increases the static electricity and that this, combined with the servo extension length may have something to do with the problem. The problem with that theory is that one of my other planes is an Ultra Stick 40 with 7 servos, 4 in the wing. It has extensions on all 4 the wing servos and I don't hear so much as a hum from those servos. They are Hitec servos, though, so it's not an apples-to-apples comparison.

I'm really hoping that someone out there has some insightful words to share with me on this.

Please help!!!

regards,
Bruce
