Graupner MC18 2.4Ghz conversion

Alright, finally joining a few people in the 21st century !

I finally moved my good old MC18 from 41Mhz to 2.4ghz using a Corona DIY module...
Install took 10 minutes, and so far, working great, but real test will be at the slope ! Weird not to have this huge antenna in front of me ! Very Happy

Never had any issues in 41 or 35mhz, ever, but now, I fear other people on the slope, as it seems that there is a general assumption that everybody is in 2.4, and will turn on 35mhz gears without checking with the other guys at the slope, and true or not, flying machines that can kill people very easily, I have to try this new stuff now that early problems seems to be ironed.

Anyway, let's try that thing with crunchies and do all possible tests before putting that in bigger stuff !
Only 3 receivers for now, we'll see, as I might move to Jeti if I go for the big jump ! Very Happy

"Get the Flash Player" "to see this gallery."

Ok, so, what's the story in the end ?

It works ! Very Happy

Ok, went to the big L. The Easyglider fully charged with the Corona receiver inside. Note that, to push the test to the max, I did not bother putting the aerials at 90 degrees and all that! I just put the receiver as it is, slided under the wings in the canopy, so basically, the aerials where more or less twisted togeter, and bent over the receiver ! Like a pig, in purpose !

And did not bother with a range check, just launched the glider as it came... And flew as far as I could see the thing, in all positions possible, and no glitches or loss of signal !
Not bad for a 20 quid module/receiver !
So, flew most of the day with the EG, and no problems at all !

But, with Keith (aka that auld guy), we pushed a bit further the test... During a bit of rain, I standed behind Keith, the TX aerial glued to his back (jacket all wet by the rain), and the EG, in the cloud !
Had a few glitches (the movements of the controls were a bit like that was step by step) but I never loss the signal at any moment ! And all went back to normal when I moved from behind Keith... A bit extreme situation, but all went great !

Conclusion : It works ! Not bad at all even, but I want to push that thing further. Next, receiver in the Alpina... But before I'll do a proper range check and stick to the plan to leave the TX at 9 stones, and drive down to the West slope.. If I still have signal there, well, all good ! (that's at least a mile away...)
