Erik Shauver’s Blitz Tech and Teardown Thread

We were testing a few parts out at hot rod last night and I got a few setup sheet post requests. My truck was great in practice and during the first qualifier heat. However, the rear grip went away when it starting getting colder.

So here's my Hot Rod setup:

I'd likely change the oil to 550F/ 500R next time. Other than that, the truck jumped great, had plenty of steering, and loads of forward bite. I'm not sure if the cold messed up the truck or if it was my hands!! :mrgreen: Now if we could just run more motor than the 10.5 rule

Stay tuned to a cool upcoming article in Xtreme. We just tested a lot of differential settings at OC/RC!

Also, for those of you nearby or with access to internet coverage, you'll want to check out the upcoming Nürnberg toy fair!

Also, try to keep this thread tech related and on topic, this isn't the place for chit chat or basic R/C questions.

7-8mm is max for the front unless you take out the internal spacer. Then you could get 9-10mm.



Sounds like you prefer a "dead" shock or a shock without as much rebound. This is great to know when you go to rebuild them again as you can start with them like that.




The Short turnbuckles are 60mm and the Long are 69mm.

400cst is the standard oil "weight." (HPI 40 weight). clic me!



The stock pistons are A front and B rear. There are additional A,B, and C pistons included so you can adjust to your driving style and local tracks.






The hub carriers are 0*, so swapping them will only affect fore to aft position of the steering block pivot axis.



Like everyone else, I was doing the Christmas and New Years family stuff! Hopefully everyone had a great Xmas with a Blitz under their tree :mrgreen: and great New Years!

I did get to make it down to San Diego/ Pauma last weekend for some great "backyard racing!!" That was AWESOME!!!! Nice track Recce01!!! I don't think it was possible for that dirt to offer anymore grip!! That was even better than clay! And nice to meet you Cheatin!!

A Hudy 1/8th setup board with some mods (note three holes)


I drilled out three holes and added expanding brass inserts


The top side gets cone point set screws


Add in a bubble level and now you have a portable flat surface that can be leveled.


add four identical gram scales and now you can check your corner weights and weight balance



I did a quick check to see what the weights were with the battery forward and also with the battery all the way to the back. The truck was fully ready to drive.

(grams)
Pack forward: RF=433, LF=441, RR=704, LR=711
Pack back: RF=420, LF=429, RR=715, LR=722

So about 38% front weight compared to 37% with a 290g pack. It's surprising what 1% will do to your steering feeling :-o You can achieve even more with chassis rake.

similar drilling of chassis as in this
tech post

-I'm shooting for more centralized weight... I would go further, but convenience aimed towards maintenance can become an issue without hand fabricating a battery strap/ component shelf. The Tekin fits in the rear "compartment" nicely.

While I'm at it, I also shortened the wires a bit and am keeping them more centralized.



note: this is still a preproduction ESE, so a few of the bits are missing...

une partie interessente qui n'est pas référencé

One step even further with the steering rack would be to flip it over. Hole 2 is standard. Hole 1 picks up more steering, entry to mid corner. I'm going to try hole "3" as soon as I can get out to race. It should take things another step further.


Note you'll need to dremel or otherwise cut at roughly the dotted line.




This is to provide clearance here.

Note: I haven't tried this yet, so it may be "out of range" so to speak, but since most of you seem to be handy with a dremel :thumb:

Reset your EPA once modified.

7. rough setting for max steering while retaining some protection... too tight like gluing and locking down the saver (YES we tried it) will make the front end unpredictable on 1 wheel landings.

Salut, je ne comprends pas cette modif', quelqu'un pour m'aider !?

Ce n'est pas une modif ; c'est le réglage du sauve servo.

Pour un bon réglage, il te conseil de mettre la partie supérieur de l'écrou à 1,51mm du haut du filetage.

Salut,
je déterre car j'ai tenté ce réglage il y a quelques jours...catastrophe !

L'écrou n'a pas voulu bouger, en revanche, c'est toute la pièce métallique qui à commencé à tourner dans le plastique. Du coup j'ai tourné dans l'autre sens pour la remettre en place, mais j'ai une légère déformation du plastique quand je regarde par dessous.
L'écrou doit être bloqué au frein filé.

A quoi sert exactement ce réglage ? à assouplir la direction ?
J'espère ne pas avoir créé une faiblesse ou un jeu.
