That's the way, get them started young. Excellent...
I'm glad to hear they held up. This is the sweet spot of Taigen. When my kids were young, I'd cringe with every jack rabbit start after spending what I consider a lot of money and time (back then at least) on a Tamiya, yet an OOB HL wouldn't make it through a complete battery under the same circumstance.
Taigen does, very cool.
