Got to be honest i have never broken one, were are you breaking them ?

DaSloth 19-07-2010 08:18 PM

I've broken a few now, but mainly through bad driving. doesn't bother me too much as they dont cost much!

the way i see it is that if you strengthen that part, something else will break so may aswell the leave the weak link the chain as the cheap part!

One thing i have noticed though is it normally happens either off a bad jump or if something around the rear transmission case is loose

GRIFF55 19-07-2010 09:07 PM

In two years of running the car, i, yes me!!! have only ever broken one:woot:, and that finished the race. really awkward landing on the rear of the car at tally. Where are you breaking yours?

Rebelrc 20-07-2010 06:39 AM

Why would a cheese slice make it stronger?:confused::thumbsup:

flipside 20-07-2010 01:50 PM

Hehe you have to be creative if you want to continue racing :) So cheese it was! (EA3 is also cheese btw)

Mine also broke from landing upside down from a jump.

But, I didn't have the rear pivot brace installed behind the tower, which seems to help for strength also! Also mount a longer screw in the tower so it doesn't get ripped out during a crash.

Cooper 20-07-2010 02:10 PM

but you did the very first time it broke, you had to drop it because otherwise the cheese wouldn't fit.

first time was bad luck I guess, after that it was already broken so it was cheesy chees.

flipside 20-07-2010 03:12 PM

No I used a very thin brace bacause i was running the alu pivot block and the std brace doesn't fit. So that didn't help much for strength.

Plus I had been dremeling the hole where the very long horizintal screw goes through, which made the tower prone to some movement, so that made it even weaker (small rotation allowed around that long screw, so the bottom shocktower screw could rip out easier)

in Langenfeld with some bad driving, here some pics

Haha langenfeld and losi towers don't match, my problems were also on that track :thumbsup:

crashingbird 20-07-2010 06:08 PM

time for some upgrade carbon towers, don't you think ?

...or even better : a chassis with a slightly longer rear with vertical mounting positions for the shocktower, all problems solved then :rolleyes:

mace 20-07-2010 07:03 PM

something like the B44 front tower would be nice on the rear end and a stiffner for the rear end like the 1/8 ones

:thumbsup:I hope AC surprises me!:thumbsup:

flipside 20-07-2010 09:02 PM

Mwah no need for extra parts if two out of so many break a shocktower... I trashed dozens of front B4 wishbones and never heard anyone asking for reinforced ones :)

rcjunky 20-07-2010 11:26 PM

The AC CR2 needs something like this

http://i696.photobucket.com/albums/v...y1/LMXrear.jpg

too bad PSI Racing beat you to it with the LMX, its a very similar car to the CR2 with the extra gear that is adjustable for differant spur gear but it uses the prefered stick packs (at least here, no one uses saddles in anything but 4wd buggy) and costs far less, for a brand new CR2 kit, it will cost me about $350ca, the LMX costed me $130 but its G10 (fiberglass) instead of carbon fiber, but judging by the set ups I've seen posted I think it handles better, you need to be crazy to run the narrow rear pivot in the back of a LMX, you'll have way more steering then you can ever get rid of. Sorry for smaking the CR2, its just not viable for me, sounds like its a good car

The Hoff 21-07-2010 07:44 PM

Looks like the LMX is for bashers and the CR2 is for racers. Even X factory are going away from the stick pack across the chassis and now making a saddle pack chassis for the X6.

True the LMX is a good price, but i have not seen it win any big meetings unlike the CR2 :)

Lee Martin 22-07-2010 08:56 AM

surely if the towers breaking at the point shown in pictures its not the mounting position that is its flaw?

Nick 22-07-2010 09:54 AM

Problem is if you land on the back tower it pushes it forward pivoting on the gearbox screw causing the bottom half of the tower to flex as this is the weakest point! Which was never a problem on the original Cr due to the extra 2 mounting points? Best way I found to fix the problem is to brace the top of the tower to the gearbox stopping if flexing if you do bin it over a large jump!
