I found a place here in California that has the same battery configuration with the same chemistry as the one Skyforce used. It's about $3.25 plus Shipping. You have to request they weld on solderable tabs but that only costs and $0.25. I've been soldering for about 50 years but every once in a while I do lift a trace. I hate those 50W wire wound resisters soldered into a .020" trace. Easy to put in and hard to get out. http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=1617 - Bill peter.rees01@tiscali.co.uk wrote: > > Hi Bill > > I did ours a few years ago (if the 3C you have is the one in an > avionics tray, not the slim one). didn' t have any instreuctions just > took the lid off and I think the top PCB (there are about 4 boards in > there) - unsoldered the old battery and fitted the new one - only took > about an hour.
