I still use a GT3B for my basher cars.
I'm looking at it right now.
Upgraded to a Futaba 4PLS a while ago, for my 'top tier' cars, but the GT3B is still 100% reliable and sees regular use.
Whenever I buy a car and fix it up to flip to make a few bucks, I'll always add a GT3B to it, to make it RTR, 'cause I know that radio is going to be trouble free and have enough features for just about anyone.
This LIPO works well in it, too...
