Hey everyone, it's been many years since I was into Rc, my dad past away and I've found a tamiya hotshot 2.... I use to play with as I youngster, in the loft, cleaned it all up, bought a nicad 7.2 1300mah new battery of the bay cheapo and all is working which has made me smile... although the run time is very low. .. so quick question to anyone in the know, can I put Nihm battery with a higher capacity in? 4200mah or higher cheers in advance, think I might be getting the bug back, just need to refresh my memory how it works....
