Hawk,
Firstly, a good turenbuckle wrench is hard to beat and there's no substitute. Once rounded, it's over and I've made the mistake of using a Exhaust hook to turn the ons with holes in them, and broke TWO of them. a Cut down 1mm allen key for ones with holes in them, or a EDS / Hudy / TM mutli are great.

It's the hidden truth to RC that the tools, lubricants and accessories are where the real $$ are spent.

For me, after several years, if it's got HUDY on it, there a good chance you've spent wisely.

Having said that, our small Tamiya cross socket that came with our very first model (Gravel hound) and the beloved Glow plug/wheel nut cross socket that came with our Kyosho inferno were the BEST multipurpose tools in our kit, they bought us the time to get on with building the whole kit and caboodle.

So in conclusion, if you havent got deep pockets, dont go for the cheap imitations, try to get a simple multipurpose tool to get you through the kit development and stay in the hobby. After a while you find that there's too many tools and you start buying smaller lighter tools to help you travel with and keep a compact modular kit.

We have a F10 Team magic bag, we just bought a FRESH new F8 version (after 4 years of F10 and good service ) we also use a Capricorrn large bag for Truers, Starters and various other items. We have a separate HARD kit just for engine maintenance, a Hudy tool bag for all the HEX and Nut drivers and the rest in the F10 now.

I'm always aware of being fearful of being a gear junky but for the most part everything we own we use and it removes the "borrowing" at races and people losing tools.

Hope you love your tools as much as we do and use them well.
