Erik Shauver’s Blitz Tech and Teardown Thread

Erik Shauver · 11-10-2009, 11:19 AM

This thread is meant to be a quick reference for the Blitz. It will cover teardown, tuning, and tech info. I will also try to give you some ideas about what to bring to the track and give you some “old school” insight into some maintenance techniques that I have learned over the years. This first post will offer links to the relevant posts.

I will try add new topics to help with tuning, maintenance, and highlighting features.

I wanted the gearbox to be as easy to access as possible. I’m not necessarily worried about screw count as I am with how easy it is to actually get to it and put it back in. A lot of the rear brace and rear bulkhead design was done with this in mind. Also, I took advantage of the pivoting of the bumpers to integrate maintenance with styling and chassis protection.

Let’s dive in!

First take out these 8 screws.

Now these two screws. You’ll likely need an x-acto knife or a dental pick to get the dirt out of the screw sockets.

Rotate the bumper and brace assembly back.

That’s it! You’ve got your gearbox out and ready for maintenance.

Rear Suspension Mount Swaps

To change the rear toe is very similar to the gearbox access. However, you take out less screws and use the flexibility of the bumpers to your advantage.

Remove these screws.

Flip the chassis over and remove these screws as well.

Bend the Rear Skid Plate up. Push the arm brace (susp mount) off the gearbox locating pegs. Then pull it back away from the truck. That’s it!

To reinstall, put the mount on both pin, then push the mount onto the grearbox pegs. Then put your 2 lower screws back in to hold thing in place while you put the rest back in.

Tech tips from the designer...Awesome

I wonder if he has ever considered being a hand model?

He's an engineer for sure, look how clean his fingernails are.

Erik you da man! How often do the designer get involved with the community on the breakdown and maintenance... just sweet! Thanks and will always check back for updates.

pastimesteve · 11-10-2009, 12:30 PM

Erik - I think you just helped sell another Blitz. I'm so impressed with your efforts here, that I'm going to have to buy a Blitz! Extremely well done and a smart move by HPI.

Thanks,
Steve

Looking forward to the tuning tips and hopefully shed some light on the leaking diff issues and possible solutions.

HPI has done an impeccable job with the Blitz, from thoughtful design to selection of materials. It's such a wonderful kit to work on.

Also, to have HPI folks on the forum first hand speaks volumes about the quality of personnel and support.

At the three tracks I race my Blitz's at, there are racers buying HPI products that would not have considered it before.

Erik and silver04RS...what your doing is being noticed.

+1 for sure

@idbdoug: Your finds with issues are not going unnoticed. If I had my finger on the exact cause of the leak, it wouldn't be there

. That said, Matt's O-ring substitution in his thread seems to be viable. It's the inconsistency of leaks that has me chasing down more information.

Erik,

I am new to Off Road and Short Course Racing and I love it! Going to save up to get one more Blitz for MOD @ Trackside!

Arigato · 11-10-2009, 03:43 PM

Erik,

I must admit that I was skeptical of the Blitz at first; I already have an SC10. However, I bought one on a whim a few weeks ago and since then my SC10 has sat on a shelf..I have my own track and have spun hundreds of laps with all my rc's and the Blitz is the easiest to live with on a daily basis. The aforementioned tips make it all the better. Thank you. I'm eagerly awaiting your tuning tips on getting this baby to turn better.

I got to run a couple of these that that Maxxis Team had out at SEMA last week. I am impressed. Looks like my Slash will be a permanant basher pretty soon
