Warning: Broken roller selector on DX8

Dumb Thumbs

I broke the roller selector and I was sick. I figured if I had to send it back to Horizon I'd be grounded for weeks Evil or Very Mad

Did a search on another forum and found a place here in the US that makes & sells metal replacement rollers and levers for radios.
Oh Happy Day!

So a word of warning, only push the roller on the TOP end of the roller as that's the end the switch is under and is made to pivot. The bottom end fits in a rotary switch and it doesn't take much to break that end.

I have read before about pushing the roller at the top but considering the roller is a major part of the tx you would think it would be made a bit harder wearing.

I had roller breakage on the DX6i, it was out of guarentee, this little bit does tend to break off.

I drilled the roller longways at 3mm, cut a B 400 feathering shaft to length (only bent on one side), filed a hex on one end to fit the rotary switch, dropped the roller back into place and have had no further problems.

Be advised - the plastic trim tabs also break. I found a site in the USA that sells aluminum replacements. I replaced mine before they broke.

Your right there Jack, I fixed mine with a piece of servo horn and hot melt glue before, thanks to you, installing the alloy trims. Cool

I do admire the make and mend here - seriously, it's the way to go (damn it, I'm a Yorkshireman!)

But I can't help thinking of Blue Peter and sticky-back plastic. Laughing

I looked at it and didn't want to risk loosing some fleeting fast good weather stick time if it broke again. Got the new aluminum roller today (only ordered it Tues night, lots faster then sending the Tx back to Horizon for repair) and had it fixed in no time. New rollor turns with less resistance then the stock one, so no more accidentally clicking when rolling, an added bonus!
