Hello, I just wanted to add I have 2 boys (almost 3 and 1 year old boys), And I maintain my wife and I fleet of nitro trucks 3 I maintain on a weekly basis, 1 is a Project truck, you just have to find the time, Sometimes I do teardowns with my boys awake or asleep, sometimes the wife helps (Sometimes!!) LOL but I found it easy to do them at night while everyone is preoccupied. Then I can do what I need. And I have a cen GST 7.7 On the way. but that just goes to you need to know your limit in numbers, I mean as far as how many are you willing to work on at any givin time,There are times I have both savages, Revo and my .30 size heli out and I do maint. on all of them at once. I had 4 electrics that I hated working on, so I solved that problem and sold them, cause I never worked on them our nitro trucks and heli's took all my time. Maybe you need to lighten your load a bit it helped me, but as I lightened the load it just made room for more nitros, LOL our collection grows all the time, its just a matter of what and how many Im willing to work on.
Good luck to you and I hope you find something that works for you! Peace!
