Waltron 4 conversion using DigiSpark 4ch+sc+V

Post by Phil_G »

I had a lucky break on Ebay last week and picked up this immaculate Waltron 4 for just a tenner Image
As its just a simple 4 channel set, I opted for the DigiSpark encoder with 4 channels, S/C mix, V-tail etc.
This time I used the 'bargain' £32 OrangeRx RF module (I dont so much mind HM Customs & Excise adding £4 VAT, but when the Post Office charges you £8 for the privilege of picking it up yourself.... Image )
Anywho, its come out reasonably well, though I used all the original pot wiring which is generally a bad idea, in hindsight I wish I'd wired it afresh like the Digi Ace.
The replacement encoder is the bit with the green LED in a transparent plastic bubble, with reversing, S/C emulation mix, V-tail mix, and an inactivity warning.
The PP3 is just for bench testing - I'll find a 2S lipo for it or use a LIDL battery.
A few pix: (Note my shed floor - anything you drop becomes invisible and is lost forever...)

Oh almost forgot to say - 50 years on it still worked perfectly on 27mhz... Image
Still to do - wire up the meter and use the DIN socket for balance-charging.

Looks great Phil, I must e-mail you sometime about a DigiSpark for mine, which cost more than ten pounds :cry:

I often use Poundland PP3s for bench testing Gary, it holds 8v but even short-circuit it will only give 100mA so is ideal for testing as it cant possibly damage anything thats shorted - whereas a lipo could give several amps.
A new proper Duracell would be fine for flying, but for PP3 format you cant beat those EBL 2S lithiums from ebay, the ones I used in the OS Pixie etc, they're great batteries :D

Back to the project, I've since updated the Waltron with the V2 software, the throttle-lock alarm is just a nicety but it matches the 7ch now which is nice.

Cheers
Phil
