I will admit that i am an architect of my own downfall- although the shop i bought from gave some truly idiotic advice.
I wanted to go lipo and asked the uk based shop where I got my radio from if he sold such an item. He said 'no - ur better of going onto ebay'. So i did just that and looked for a tx lipo for my ko ex 10 helios.
I simply balanced charged the damn thing as i could any lipo. I then plugged it on - no whizz no pop - simply drove up 80 miles to silverstone having got up at 5.30 - hey presto - no radio
I writing this coz o don't want anyone else to have the same experience.
