Thread: How To: Spektrum DX7 LCD Back Light Mod.

changing regulator can only be a safer option than cheap spektrum part in there now.
BMFA and the like should be promoting an upgrade like this not hiding behind paper work.

This is why I used a switch. It can be turned off and not used when flying.

The only change to the Tx from std., is a much more energy efficent voltage Regulator, so your not wasting power as heat on the linear volt reg.

I would love to know how a Mr Curtis Youngblood can fly in comps with a heavily modded Tx (cuddle box)?

I'm not saying I agree with it Rob, it's just one of those things we have to be aware of in this country.

I've got limited knowledge about building setup of heli but how many kits/engines and electrics have a CE mark? We play around and make changes all the time with them.
And people setting said helis are certirfed with paper work and i don't mean A,B and other BMFA ?

As far as I know nobody cares about that bit but to fly at a competition they check two things ...... BMFA B cert and whether your tx is CE certified, if it's modded then it isn't. I'm no expert on this but I believe CE certified equipment is a condition of the insurance, which is why it's checked.

Please don't shoot the messenger.

DX7 Backlight Modification

Brilliant guide, many thanks Rob. If only I had one of those DX7's...I dream on..hopefully one day...=)

CE certification is an electrical test, so you are fine to open the tx, change stick tensions, bearings or whatever. The moment you introduce new wiring of any sort the tx is no longer the same electrically and the CE cert is invalidated. That is my back of a fag packet understanding of it.

Thanks for putting this 'How to' on your site. I hope it is of use to some people.

Quite the opposite Rob, we should be thanking you

was going to mention the CE thing as well (but see it has been covered).

Excellent job Rob.

Right, Shoot me your address then you can do mine now for some beer tokens..

I soldered my power points to the fuse board instead, right by the fuse but other than that did exactly what Rob did.

Well done Carl,

Now just step back and think what you have done,

The world will get hotter

The sea level will rise

More polor bears will be homeless

The moon will go out of orbit

I hope you can sleep at night knowing what you have done now
