Gorilla Straps

[gorillamaxx]

Nick - Since the G1 chassis only had 7 cell slot, if you run all 7 flat you wont need to lace the strap.

If you run the 6+1 hump back try the following - Attach the small buckle strap at the rear (using the bonded washer). Attach the long strap at the front (using the bonded washer) - set the hump pack towards the back of the chassis plate with the hump cell also at the back - this will leave the first cell slot open at the front. Now take the long strap and drop the end into the narrow slot next to the mount - then bring it up through the first battery slot (the open one) and then lace it into the buckle. This will lower the tension point and create a stronger hold.

Try it.

Right - I tried it, and the battery fell out again! Although I think I have located the problem.

No matter how tight the straps are and in your soloutions the battery slides horizontally out from the strap towards the motors (to the center) and then the strap isn't covering it, allowing the battery just to come out.

I guess if I make some sort of bar on the other side it will stop them sliding out that way, even a little bubble type rib with duck tape should stop it.

A suggestion in my own experience is make the next straps wider.

Please suggest any more soloutions.

I have "e-maxx" packs, 7 cells w/ da' hump.

I could have modified the "7th" cell and layed it flat, but I'm going LiPo pretty soon and I'd like something that'll ensure my expensive batteries will stay in the truck.

So I was on the hunt for something fairly easy to modify that would hold my sub-c cells in the truck, didn't want something difficult to work w/...and definately not something heavy.

Found that a single gang pvc electrical box is perfect. It's lightweight, just the correct width, one box makes a complete cup, and it cost $0.89 + some heavy duty double sided tape I picked up.

I basically cut the bottom and top off (bottom and top make the cup), left the cup tall enough to allow the g-maxx strap to hold the battery in the cup, which means the battery hump was exposed and the regular portion of the battery was slightly exposed. I ground down some of the various unnecessary "humps."
Don't really care for the double sided tape but it didn't have too much trouble providing horizontal support, though after a couple runs on the track there was enough dirt and movment requiring me to put on new tape. It would be easy enough to modify the plastic cups to allow the g-maxx strap to run through them or "join" the cups w/ epoxy, aluminum, anything else light and slim.

I didn't endo my truck nearly as much as I used to, getting proficient w/ the throttle on jumps and corners helps....so I didn't get to test very often, but of the few times that I had an 'incident' the batteries didn't move.

LiPo's are a little wider than sub-c. Approximately 7mm wider, I believe these cups make w/ work them also.

LOL maybe its just me but I ripped 1 blue strap a few weeks ago clean of just turning. Alittle dispointed but what can you do things break. Gorilla maxx is awesome! The strap came in handy for another use. Check it out lol

DId some revo trimming lol

Well I am trying to make my own DIY gadget to hold them in.

Real disappointed at the Gorilla straps, they need to be another 1cm wider and it would do all the difference.

Thanks for the help so far anyway guys. :)

I was skeptical of the straps providing enough lateral support when I first installed my chassis (I love the chassis, btw).

The gmaxx straps are fine if you have something else that will provide the lateral support necessary to keep your batteries in place. Granted you would think the straps should be enough, but I had the same experience as yourself. Used zip ties, extra velcro, etc. Nothing worked solidly enough until I decided to make the cups.

If you read my post above you'll see that a very inexpensive and easy to craft solution is available. You're looking at about $5 and an hour of your time. Oh, you may wanna sand the cups and paint 'em...so another $3.

Maybe you'll come up w/ a good enough design and can market the N-maxx cups for the g-maxx chassis, sell 'em for $10. :D

I'm thinking of making my own straps, based of the Gorilla ones, but wider and a "belt" type buckle instead of velcro. ;)

You could always make something like those tie downs used to hold things in pickup trucks where you crank it down to tighten it...

Nick,

I'm still not clear on your last comment about the pack sliding out to the center. I didn't get a picture from you - so I mocked up what I think you have using a few old parts. The washers should be tight - to work properly you need friction to hold the strap down at the mount, otherwise, the only thing holding the strap is a small little hole in the velcro.

Just so we're all up to speed - This is a photo of the old G1 chassis with a current G3 strap.

The new chassis (not shown here) uses a foam pad with the strap to hold the packs firmly in place (yes- the foam is important because it creates a non-skid surface)

[gorillamaxx]

I just cant image the pack sliding out from the center - it would have to get past the brace - Is that what you mean?

[Nick]

That is exactly how mine is set up now.

But, if I have a bad roll, the velcro comes slightly lose and allows the battery to come on its side where the arrows are, then come out over the Gorilla straps.

I hope you understand?

[gorillamaxx]

It would really need to come apart for that to happen. Sounds like the velcro on your straps is not holding. Velco usually needs to be pealed apart. It could be a bad piece of material, or perhaps the material has been soaked in something making the hook and loop not connect. Email me your address an I'll get you a replacement set - mail@gorillamaxx.com

Must be, if I remember when I first used them it was in Snow.

E-Mail sent, thanks alot. :)

I broke my gmaxx straps also but i have a very simple fix. I took a neddle and some thread a sewed them back together. I'ts been 3 months or longer since the repair they are still working great.

Nice! Good to know!
