Now people, I've got a lovely little T-rex 450 SE v2 but a really long aerial, what to do, what to do.

The receiver is a Hitec Electron 6 and it comes with a bobbin but need a better solution. Not sure where to run the aerial and the supplied tube only takes about a third of the aerial.

Post some pics of what you have done please so i can look see.

Thanks Guys
Cheers,
Jeff

That's the great thing with the DX7 and it's receivers (2). No antenna issues at all.

deans base loaded antenna or Quick UK is the best option i have found. however you can just coil that long arse antenna around the antenna tube and it works pretty well, just don't double back on yourself with the antenna. the rx is best to be at the opposite end of the helicopter, to the end of the antenna. another suggestion is don't coil the first 4 inches of antenna and also don't let any of it touch carbon fiber, if you need too you can put fuel tubing over the antenna in the places it requires protection from the carbon fiber. i'll post a picture as soon as i get home.

i'm on 36mhz it's even worse :P

Thanks Daz,

Where in Australia can you buy the Deans mini antenna, looks like a sweet option. But also thanks for the advice of the antenna route.

Cheers,
Jeff

OICU812,

I like what you did with the Ar6100 concerning the antenna wires. Is that epoxy where the wires come out from? Think I'm going to try that.

OICU812, you have doubled back your antenna you have effectively canceled out 4 inches of antenna, it may work but it's not ideal.

with 36mhz, i require 30cm between the rx and the base loaded antenna, so i put the rx at the front, with fuel tubing around the wire until it gets past the carbon fiber, then a have drilled a hole for the base loaded antenna right near autorotation tail gear. near the spacers, and i have the antenna pointing up at about a 30 degree angle so my antenna isn't running parallel with the boom or anything else metallic.

Daz, well I do not run that system anymore, I am on Spektrum. However before you critique know that there was a full 4 inches of antenna wire from rx, then soldered to the Revolution Whip wire therefore it was fully correct in length and range or glitches never were an issue ever with that routing method.

hi OICU812, as i said it will probably work without fault and as you said you didn't have any trouble. however as you have created like a "U" shape with your antenna you have cancelled out about 4 inches of antenna theirfore you basically could of soldered the deans antenna directly to the rx, it probably wouldn't of been any different. just an observation. with these small helis it is extremely hard to route antennas and i know everyones frustration all too well. 2.4ghz is gunna change this but

Cheers

Put the antenna through a small antenna tube, and then wrap the excess in a tight coil on the outside of the tube. Slide a piece of heat shrink over it and shrink it down. Home brew base loaded antenna of sorts.

Worked fine for me until i switched to the DX7.

Where did you get the wire covering, and what is it called?
It's clean and looking sharp.

Thanks. However, the gyro in that picture is no longer with us. Some people learn the hard way.
