they are gen 1. they are alot weaker. why dont you get the carbon fiber holddowns?

Actually - the ones shown on the photo are G2 straps. From reading your comments (Nick) I think you might not have the straps installed correct. The large washer that comes with the straps is an important part of the strap connection. The bonded neoprene is designed to squeeze the strap down to the plate. If your strap is tearing at the holes then you probably don't have the washer tight enough. The velcro connection is the same on all the straps G1 G2 and G3 - its velcro.

Any chance you can send me a photo of your truck showing how your straps are installed?

Only pictures so far and as you can see, I havn't been using the washers supplied as the screws supplied arn't tall enough to attach the metal support bar to the frame and give enough space for the washer. :(

This wouldn't be a reason to why the velcro gets loose though? Or batteries fall out - obviously they will if the straps ripped but they have only ripped once when the batteries have fallen out several times.

Also, are what Gorilla straps are mine? G1/G2/G3? Those metal ones look alot more rigid/stronger.

You straps are g3. Some of the earlier ones actually had more strength to resist ripping, but the velcro adhesion was not very strong. The g3 straps have prettys strong velcro. Here is a suggestion to try. You mentioned that you run 6 cells flat with an additional battery on top, right? Try tucking the velcro into the slit in the lower chassis plate opposite the humped battery before you cinch it down(run velcro down through a battery cut out and up through the slit in the chassis). This should give you some extra pressure on the batteries. I would double up if it were me
(I already mentioned this).

This doubling of straps, Mike, do you mean two parallel? Or one over the other?

One over the other is the way I do it. I hold my $$ LiPo down with this method and haven't had any trouble.

How many cells are you running? The problem is that the velcro is higher than where it supposed to be. Because of the cnc'ed lower part of the frame. Depending on how many cells you are running, you could consider mounting the velcro on the bottom of the frame, leading it thru the frame, so it pulls down harder. just use a small piece of lexan or what so ever, to keep the velcro intact where it goes thru the frame.

That is your problem imo.

Nick - The Straps are designed to fit the stock chassis and the current G2 chassis - This is why the screws are not long enough for your application (because of the side rails). You definately need to use the bonded washers at the mounting locations. These will give you a much stronger hold point. Mike is correct, you should lace the straps through the slot on the lower chassis - this will keep the batteries from sliding foward. If your velcro is not sticking, then you might have a problem with the velcro material. Check that the hook side is not flat or damaged and then check the loop side is not worn. If you think the material is defective let me know (email me at mail@gorillamaxx.com) and I'll get you replacements.

I run 7cells, 6 cells flat and 1 cell hump at one end on top - although soon I will be running with all 7 flat.

I will try lacing the straps and maybe some longer screws.

Just to make sure, to lace, after the last cell I put the strap through the hole the cell sits on then back up through the thin slit at the end, then fastend by the screw?

Thanks alot for the information so far, this is brilliant support.

ha....thats nothing. I run 7 cells on one side and 11 cells on the other - in a stock chassis. The side with 7 cells has one slot cut out, so from the top it looks like a flat pack of 6. The side with 11 cells has all five slots cut out, so that also looks like a flat 6 from ontop.

I use gorrilamaxx straps and both packs (including the 11 cell pack) are helf very securely. Plus the CoG is much much lower.

Got a picture of that? Sounds intresting. 18cells on a stock chassis, couldn't belive it until I see it. :D

I'll try attaching these 2 images. The reason there is a big hole in a centre of the chassis is because I used to run an 820 dewalt/tekin 420-g2 set-up, but that didnt work. Now I'm going for a 2000XL/warrior 7018 combo, should give nice speeds and runtimes.....

Thats very unique, good job. :)

cheers :D
