guys,

what do you use as far as extensions or whatever to get from your receivers to your elevator servos on a 40%?? just heavy duty extensions?? or some kind of amplifier?? what brands??

thanks
tony

My 38% Extra has plain old flat 22 gauge wires running to the elevators in the rear. Total run including everything is about 44 inches. They run inside the same paper tube and within about an inch of the antenna as well. No problems in several hundred flights. Each one is 36 inches long with a plug at each end.

I have also run as long as 48 inch extensions in large gliders without a single problem.

Hi Tony,
Off the shelf high quality 22 gauge extensions are just fine. I've been using stock JR extensions with no issues. If you want to make your own so the length is just right, Custom Electronics, Hitec, Cermark, and probably others I'm not remembering, offer good quality twisted servo wire. If you want to get a little fancier, Simon Van Luewen will custom make a complete set of high end harnesses for your setup.

Like Ty said, make sure they are of good quality. Stay away from connectors that don't use gold plated ends. Also, make sure you use some way to keep them together under vibration. I use 3/8" shink tube for those connections that I don't need to take apart for tranportation and J-tec keepers for those that do. I've used Cermark, JR and custom harnesses from RadicalRC, none have given me an ounce of trouble.

i'll echo the off the shelf route...everyone i know who labored to make their own connectors swore they will never do it again - including me. simple is good. on any connector, give the individual wires a slight tug to make sure they are properly seated in the connector.

ground breaking is a not a term to be used lightly in rc

thanks guys.
thats what i was hoping.

is anyone using some kind of buffers or amplifiers??

thanks
tony

No

I'll second his "No"

I'm using a Glitch Buster in order to have an 8 volt bus that the extensions plug into. At the end of each elevator extension I place a 6 volt regulator rated at 1.5 amps. On the ailerons and rudder I make a y harness with a regulator at the end of each end of the Y. Each servo plugs directly into a regulator output. The end result is each servo behaves as if it is the only servo plugged into the receiver and you don't have to worry about voltage drop in the long extensions. If a servo stalls or shorts out everything else keeps working and that regulator shuts the high stall current down. The GB also buffers and amplifies the signal pulses.

OhD - where do you buy the Glitch Buster and the regulators. Also,
what do the regulators weigh??

The Glitch Buster comes from EMS-Jomar and the regulators are custom Jaccio that you can get from me if you want to try this system. It is far cheaper than these power distribution boxes coming from Germany and you still have to worry about voltage drop in the long extensions with those devices. You also need to plug in multiple aileron extensions with those because you wouldn't want to us a Y harness in the wings like I do. The regulators weigh less than a half ounce and cost about $10 each. I have 8 of these plus a standard 5 amp regulator to power the receiver, throttle servo and engine kill switch. I make a simple mod to the GB so the pulse amplifiers run off the regulated 5.7 volts instead of the raw Li-Ion 8 volts.
