Hey guys.

just got my first set of 3S Lipo's for the maxx, and another set of Zippy 2S Lipo's

the 3S are Dynamite RC 5300 Mah 25C Lipos.

and got the Big Bore aluminum shock kit as well. but strangely the "Big Bores" are actually smaller than the stock Ultra Shocks.

Same reason I didn't buy the 'Big Bore' shocks for my slash 4x4 :D

Just had a bit of free time so upgraded the Maxx with all the parts which i recently acquired.

and the stock battery hold downs were too small for Lipo's, so made my own battery straps.

List of upgrades:

Proline Baja Bug Body
RPM Upper and Lower A-Arms.
RPM Shock Towers with body posts.
GH Racing Aluminum Bulks.
Traxxas Big Bore Shocks.
Hitec 7945TH steering servo.

and the Diffs were fully serviced and filled with LRP Diff oil.

a few pics :)

Looking good... There is a good chance you won't have to buy E- Maxx arms from now on.... ;) ;D

hey,

i have been constantly popping off shock cups a lot. but luckily havent lost any of them till now. they keep getting wedged in or careful retracing has resulted in finding them somewhere in the area.

i remembered that Rajat had a mod done for his XXT which tied the cups down with a piece of wire.

but mine have no holes to do that.

so i improvised a bit and used a little bit of heat shrink tubing on the cup and the last coil of the spring. pics below. hopefully this will keep them safe.

Nice and simple mod. I'll do this on my slash just incase....

Nice idea. But what size of heat shrink is this? I dont see anything that can cover a 8 scale shock cap.

ajo sir - the heatshrink when flat before heating is 2.5 cms wide.

i took one of the shock and spring to the shop to get a proper size one.

will post a pic of it once i get home. and if u cant find one there. let me know. i can buy here and courier it to you.

another small mod for the maxx.

the stock steering bellcrank system has two posts out of which the slave post has bushings on it. according to traxxas forums this is what causes the steering to have a lot of slop in it.

checked mine and yes it had a bit. not a lot. but a bit. and there are two ways to fix this.

either remove the slave post and out another servo saver post there - which is supposed to be the best way because that has bigger bearings.

or find bearings small enough to replace the bushings.

so after searching all the bearing shops i have been able to find suitable bearings and yes it does make a difference. very negligible slop now.

pics below and a few pics from today's run.

Servo is doing well. no probs till now.

As some of you know my Emaxx took a dip in the ocean. i was going through the photos from that day and i actually captured one pic showing the maxx about to be pulled down.

and u can see the GoPro actually on the maxx in the pic. so i have on car footage of being drowned :P

and also uploading a small teaser video of whats to come in the next vid. GoPro footage also included.

thx.

it actually records in full 1080P HD. but i had to size it down a lot. otherwise it would take too long to upload.

and the best part of the GoPro is that it comes in a waterproof, dustproof and shockproof case. its a hard case which can take a lot of bashing.

and comes with a variety of mounts which can be used for mounting on almost everything.

btw i tried the cell phone taping thing. did not work. one blip of the throttle made it wheelie and flung the phone off.

ok. update after a long time. one of my lipos caught fire. pics below.

finally decided to retire the stock shell which came with the E-Maxx, it took a lot of abuse. was reinforced with a lot of duct tape. but finally gave up.

and a new vid as well. any comments and suggestions are always welcome.



older vid removed and reuploaded as there was some problem with the sound

lipo puffed up enough to break the casing tabs, actually both of them. dunno if the truck drew too much. had timing on low and gearing is stock. so no idea.
