I bought a new Solo off Craigslist from a "not very bright" young man, he used the wrong charger (not sure how he managed) to charge the controller and fried the charger circuit. I've flown the Solo several times and everything works great, I love it. I just cannot charge the controller battery in the controller, as a matter of fact if I try, the controller discharges the battery. I'm looking for an after market charger to charge the controller battery. Any ideas? Thanks
