EDS strip real easy...Tried Hudy and they were not that good either. Only wrench in my box is an MIP . Dont use ball ends or power wrenches when assembling...it will strip.

I worked in the hobby shop for 4 years at OCRC and West Coast and the only wrench I use to build kits is an MIP. Kyosho screws are much higher quality than most companies.

Second that MIP or have to break out the screw extractor bit. Kyosho is the only plastic which is perfect for power tools with clutches IMHO. Xray is so stiff it chews up and strips everything(predrill with a cap head m3 works best for me). Losi is so bad it just spins and melts.

Agreed. MIPs are fantastic.
(And especially about using ball drivers; only use them if you can't access the screw any other way)

what tools are you using?
Hudy but it is a bit old. My fault probably for not being careful enough. I do love MIP/Thorpe. Buying them now instead of Hudy.

I am sold on Kyosho! I will post pics of the car tomorrow
There were about 2-3 people yesterday at TRCR that tried there rb6 for the first time. They all were sold on it pretty quick.

That's great news.. and that is saying a lot considering TRCR is a die-hard AE track... owned by Team Driver Scott Brown, and with 3 or 4 national level AE team drivers that race there on a weekly basis...

K team driver Ryan Matesa is usually in attendance who can help get their cars dialed in. (and im no guru, but im always happy to help with setups as well).

I'm hoping to be picking up the rb6 myself pretty soon.
A lot of AE stuff and drivers at TRCR but everyone is extremely nice and helpful.

Funny story,
My buddy was taking off his shock at a race recentely and he was complaining that he stripped his screw (He was using a losi 2.0). Well I use a MIP 2.0, I've had for 18 years now and its been known to get screws out some other tools just can't. I went over to his car and unscrewed it no problem, screw wasn't even stripped, his 2.0 was just crap. His driver was stripped, in compassion I couldn't believe his was actually a 2.0. He had this losi tool for less then 2 years.

Seriously 18 years and I've built quite a few cars with it, it still works like new it's amazing!

MIP or nothing when it comes to tools
