Thread: Receiver losing bind with servo use
28/08/2017 22:32:45

Thanks, I'll try removing the horn, it's closed loop actually so it could be tightening up a little.

I have a pair of Corona servos (DS339HV)  in a small plane which was running 35meg. I've decided to drop in a Spektrum 2.4 receiver for the finer adjustments possible.

Strange thing happens when I move the rudder servo the receiver momentarily loses bind, then it's ok for a couple of seconds then it loses bind again. If the servo is motionless the elevator servo works flawlessly.

I've tried switching outputs and a different (larger) servo plugged in, it only throws a wobbly with this particular servo, I've even tried another Spektrum receiver with a different spec, same result.

So is it possible for a servo to make the receiver lose bind and if so, what can be done?

Don't wish to be a party pooper Mark but that's not very good taste, I'm not laughing now and I wouldn't have laughed at the fringe.

Hi Howard,

Can't answer your question but to post a pic go to the top of the page and click on 'Albums', this is where you have to upload pics to before you can import them into your post, this is done by clicking on the camera symbol contained within this reply box, easier to do than say.

Thread: Spektrum AR600 Aerial Lengths
21/08/2017 21:13:13

Thanks Denis, didn't think to google it!

21/08/2017 20:59:01

I have acquired an (old) Spektrum AR600 2.4 6-channel receiver but the aerial lengths seem a bit odd to me, one is 21cm with 3cm bared at the end the other is 6cm with 3cm bared at the end.

Is this correct? (Ignore the bolt it's only there is keep the aerial in the picture!)

Thread: Flight Time Cut in Half!

Cliff, you mentioned in the OP running at mid throttle for around 22 minutes. Does this mean that you normaly fly until the LVC cuts the power or the power drops & you then land ?

Hi PatMc, I can land after 22 minutes to leave about 30% in the battery., the motor at this throttle setting is drawing about 2.5amps if memory serves, it seems as spritely at this end of the flight as at the start.

This morning I flew for nine minutes with 70% left on the new battery.

20/08/2017 19:57:01

The batteries are 1300 Zippy's with less than 10 balanced charges each, I do leave them fully charged though and they were both puffed a bit.

I just tried a new battery and all is well again, nice long flight times, I deduce the batteries are knackered, perhaps leaving them fully charged is the reason?

Thread: Sheep Eating Cars
20/08/2017 19:48:09

All very interesting replies but no real answer to the problem, I've borrowed one of those car/dog/squirrel/badger sonic repellers to see if that has any effect, you never know.

The sheep are eating the cars hence 'sheep eating cars'!

For what it's worth we tend to land in the lift due to locations, this is done by crabbing in low, may be a couple of feet of the ground, and when you turn into the wind for a second or two you'll be hovering and losing height and, bingo, you're on the ground! Perhaps easier to say than do but if you're too high you just go round again and come in a little lower.

You want one of these on committee.

Very good John but I don't think the farmer would be too impressed, perhaps a card-board cut out laugh

We rent a patch from the sheep farmer which we surround by an electric fence, this keeps them off very nicely.

We have to park however in the main field which has curious sheep wandering around.

Question: Do you have sheep in your parking area and, if so, do they bother parked vehicles and, if yes, have you found a way to keep them at bay?

By 'bother' I mean they tend to chew on any piece they can get their teeth around, usually around the edges of vehicles, this, understandably can be costly.

Thread: Flight Time Cut in Half!
14/08/2017 20:26:15

My little KK Pixie uses the running gear from an old Ultrafly Outrage, the motor is a brushless B/06/10, the ESC is the one that came with the model.

I fly it on a 3S 1300 battery, on a mid-throttle setting this gives me around 22 minutes in the air.

Flying yesterday in perfect conditions and cruising around on half throttle I lost motor power and glided safely down, the BEC seemed to cut in, I'd only been in the air seven minutes.

I tried my second battery, which was also fully charged and got a similar result.

Today, having charged the batteries I plugged in my watt meter and got these readings, at half throttle it ran for approx. seven minutes, whilst drawing 2.5A at 26watts, watching the voltage it dropped to 9.0v when the BEC cut in, this is probably correct.

So my question is what could have changed since the last time I flew, why all of a sudden the truncated flight time?

Any ideas?

What was the supposed logic of changing to B - it certainly escapes me!

I'd be very interested to know this as well, I agree with Frank 90 deg clockwise, I would feel most uncomfortable with 'A' and Tom, I'd see you in the next club as well, there's no way I would be in 'B' unless I was the only one there.

We had a request from a holidaying Swiss pilot, Rene and his wife Mia, if they could attend our field to fly an electric glider, Rene usually flies either in the Alps or Spain, what a beautiful machine it was too, here's a short video of the morning.

This is a close up of the 'mystery circuit' tapped off of the battery wire the black and red wires read 5v. The picture below shows the esc with the usual connector for the receiver (throttle), The black and red wire read nothing, but the black and white read 3v, this, I'm guess is not right, as the white wire should be the signal? As I said above if I plug the plug reading 5v into the receiver it powers up the servos but not the esc, so Bob, when I plug the plug from the esc into socket 1 and the 'mystery' plug into a spare receiver socket the motor now fires up as it should but am I not putting a total of 8v into the receiver?

The plane is designed to have the option of an fpv camera so I think the 'mystery' circuit powers that via the 5v plug, if I had that installed then I wouldn't be able to power the receiver on just 3v so, yes, I can fly with both plugs in but a) will it cook the receiver and b) the esc should be giving 5v surely?
