You will need a good set of hex wrenches the L shaped Allen's that come with the kit are not nice on the hands. It will take 12+ hours on your 1st build so set aside plenty of time and be patient. The most reasonable set of tools is the dynamite brand. They are decent quality and they won't break the bank.
This was my 1st set and I still have them in my box. I use Judy tools but these are still around.

If you can spend a little more this set is worth is.

And you will need a 5.5mm wrench as well.

You will also need a pair of needle nose pliers and a glow plug wrench and 17mm wheel nut wrench would be nice but the kit might come with something. Hope that helps. BTW I'll have to check but I think I have a tool that came with the Losi cars that has a wheel wrench and plug wrench on one end. If you want it pm me and I'll ship it to you. Just pay the postage
I just looked and I have the wheel wrench and an old plug wrench that's yours if you want it
