After bashing for 20 years, I'm ok with "playing with toys" at this point. I either want my trucks on my rack ready to bash or out bashing. Time on the bench is wasted time to me these days. Just getting them built so they can take minimal maintenance to make it through a hard day is my goal with every truck now.Loving to drive them more than working on them just means you like to play with toys. If you love working on them more than driving them, then that means it's a hobby. For me, this definitely a hobby. This is why it's really hard for me to by and RTR or a used vehicle. Building it is most of the fun.
Milwaukee tools are my favorite power tools. Yes, I have all the big brands. The MIP hex drives are the best hex bits. I have had my fare share of grinding hex ends down. Especially while building Kyosho vehicles. Those plastics are really hard to tap with a tiny bolt. No issues with the MIP bits.
Have you tried using the M12 soldering iron? It works pretty good. It just takes a couple minutes to get hot enough. Once it's hot, it works pretty fast.
