guidelines

Hi again,

Because modern radiocontrol transmitters have enough rf-power and receivers sensitivity and selectivity are very good, and the controlling distances are quite short, we can more easily mount our antennas allmost wherever we wish and they work well. However, what i wrote down, are the basic guidelines for proper mounting of the antennas, and they should be take into concideration when mounting antennas, and when hoping the best performance, antennas should be placed to the best places.
And on the edge of the performance, even the minor details do matter.

About the regulator..
Have you done testing with the measuring devices like spectrum analyzer? What i'm after is, that even if it does work with your receiver and in your freq. it might not work as well with something else. Testing only in real life situations does not give us that much information from its behaviour in every circumstances.

Boy I feel for ya Alex, im going through same thing trying to figure out what caused the my wreck. After reading this post where do you start? There is sooo many variables to the radio issues. Its almost
like the type of radios we use for this hobby are subject to to many
small problems. Wish they could come up with a little more reliable
radio type so you wouldnt have to worry about things like where the regulator is, placement of antt., to close to ignition, vibration,
ect. Does anybody know where a list on "what to do" and "what not
to do" on radio related items we could get ? Its hard to get your confidence built back up when there is this many variables to deal
with especially when you spend lots of $$ to rebuild, the last thing
you want is another crash.

Getting a list is easy. As you can already see decifering which opinion is right is always the hard part.

Hi Aschuck:

As far as the Base loaded antenna is concerned, I have had excellent results with Revolution whip antennas on both a standard PGasser and an SE with Carbon fiber frames.

There are several critical factors when using these antenna's, as pointed out by others on this thread. One thing I will add to this is to use the supplied male/female connector pins included in the package and solder them securely between the RX and antenna. Leave about 4 inches of the original RX antenna when you cut it, and leave an inch or two on the whip antenna side. After you have the connector pins soldered on to the wires, measure and cut several lengths of heat-shrink tubing and slide them onto the wires as shown. Connect the pins together, then slide the heat-shrink over the connection and shrink it down completely all along the length of the wire in both directions. Then route the protected wire up and out of the RX and over to the antenna.

This method provides a solid connection that CANNOT come apart in flight, prevents chaffing, and provides strain relief for the wires. I've attached a picture of my original installation on my PGasser. Hopes this helps.

Sorry, I'm having trouble getting pictures to load up on this website. I will try again later.

lock out

Its funny that this post came back up. Two days ago i had a lock out with my condor. I did not have fail safe set. It drifted to the right as i did not have any control of it.then it slammed into the ground. Before i lost control of it totally it was glitching but didnt give me time to set it down. I looked at my antenna wire and it was cut up near the reciever from the edge of the CF. I think this is where it recieved stray rf. But the thing is...I had been flying it with no problems. Maybe it was interference from an outside source? Idk. But i Know when i spend the 800 to fix it im going to fix it right and set fail safe.

If the connection needs to be that solid why not just solder the two wires together and forget the pins?

Because you loose the feature of the connector for use when you want to remove the radio or the antenna from the model. With the heat shrink tubing installed, all you have to do is remove one layer of heat shrink and the connector can be taken apart...put it back together, install another layer of heat shrink, and you're good to go again.

Failsafe always

Always always always set failsafe. While it is for safety, it also prevents crashes more than you think. If you had failsafe you would have flown out of that and landed instead of watching it drift into the ground.

Hear here! I won't even start my gasser for an idle run without setting the throttle channel fail safe. I set it for cut, then start and set the idle speed, then re-set the fail safe for this idle. Only then will I consider the heli is ready for a test flight.

It breaks my heart - really

And set it for low throttle ...

Raja pounded it into my head and it finally stuck.

I was having nightmares trying to get the lockouts to end on my 2nd Futura se Gasser. I tried everything I could think of sheilding the ht wires, putting ferrite rings on all the leads, re-routing the aerial wire etc etc. Every time I advanced the throttle the cyclic servos would all start to glitch and at a certain rev the throttle would cut and the receiver would keep going to failsafe. It took me about 2 hours to find the cause of this, in my garage.

Now I have 2 Robbe Futura se's and the other one has been/is perfect can be looped rolled and flown into the distance with no glitching or lockouts so far. The installations are identical on both machines except that no 2 has carbon frames. They use the same receivers servos gyros etc.

This is what I thought the problem was carbon frames, but NO! there was one other difference between the 2! the one that is fine has the receiver wrapped in lots of soft foam, and the other one with problems I simply had about a quarter inch of one sided sticky foam stuck to the bottom of the receiver and stuck onto the mounting plate like that! now when I released the receiver from the frame there was no more glitching or lockouts! i.e with the rx just left hanging down it was fine! put it back on the mount and it locks out again! soo all I did was wrap the receiver in plenty of soft foam and have it mounted loose but securley to the front tray and NO MORE LOCKOUTS! I am amazed at the difference this made the Futura is now just as good for range as NO 1!

So to sum up all that was causing my lockouts was VIBRATION THROUGH THE FRAME!

I always have got away with using the foam that I had on this receiver with other helis, i.e raptors hawks etc, but not with a gasser!

Hope this helps!

Dave

Dave,

An interesting test, and I think a more meaningful test, would be to mount the receiver in #1 like you had in #2 and see if it locked out. I suspect there is something wrong with the receiver in #2 that made it lock out with vibration and if so, it may reappear in the future with even less vibration.

I tried that, or similar allready as I did attempt to get rid of the glitches by swapping receivers altogether, the ones I use are Multiplex IPD Synth Dual Conversion 9ch, but I also tried it with a JR 700 and also with a 900 jr with the same results. in fact I had the JR Rx in first and thought the IPD Receiver would be better which it was but still gave the lockouts.

Volt Magic will detect glitches

I think if you get a volt magic it will detect glitches for you.when you finish flying if the glitch light is blinking green you have a glitch.If I'm not mistaken a good way to find out
