Another Gmaxx is born
After the sale of my beloved TXT-1, I used the money to fund the start of a Gmaxx project. My original inspiration was Juju's truck. Lie- I wanted a truck just like his so I practically cloned it, using some 'borrowed' images as a guide. Here is the result so far:-
http://i115.photobucket.com/albums/n...eil/gmaxx2.jpg Towerhobbies delivery of parts http://i115.photobucket.com/albums/n...eil/gmaxx3.jpg G2 chassis and extension from Rc- monster; had to pay £20 for import duties... http://i115.photobucket.com/albums/n...eil/gmaxx4.jpg Figured out why the HVmaxx wouldnt work after I pulled it from the TXT-1. http://i115.photobucket.com/albums/n...eil/gmaxx5.jpg Replaced wires with slightly thicker ones. http://i115.photobucket.com/albums/n...eil/gmaxx6.jpg Chassis was easy to build. http://i115.photobucket.com/albums/n...eil/gmaxx7.jpg Extension looks really nice. http://i115.photobucket.com/albums/n...eil/gmaxx8.jpg Different view, you can really see the curl of the lower plate edges. http://i115.photobucket.com/albums/n...eil/gmaxx9.jpg Yet to sort out the wiring properly. http://i115.photobucket.com/albums/n...il/gmaxx10.jpg I could have just bought some cheapo stock parts to make it runner at this stage. http://i115.photobucket.com/albums/n...il/gmaxx11.jpg But thats just not my style, not that I have any that is.... |

Bought some 3.3 diffs, 3.3 slider shafts, 3.3 axle carriers, 2.5 tie-rods, some emaxx slider to mod up for us as center shafts, and a GPM bellcrank. http://i115.photobucket.com/albums/n...xx/gmaxx12.jpg Added some integy gearbox collars for bling, and realised the tie rods were too short... http://i115.photobucket.com/albums/n...xx/gmaxx14.jpg MSR4 piggyback shocks. http://i115.photobucket.com/albums/n...xx/gmaxx15.jpg G3 race skids arrived from Gorillamaxx. http://i115.photobucket.com/albums/n...xx/gmaxx16.jpg T-maxx shell turned into a Gmaxx shell.... http://i115.photobucket.com/albums/n...xx/gmaxx17.jpg It'll do for the time being. http://i115.photobucket.com/albums/n...xx/gmaxx18.jpg G3 front skid fitted, I have the rear skid & rear upper plate as spares. http://i115.photobucket.com/albums/n...xx/gmaxx19.jpg Tidied up the motor wires. http://i115.photobucket.com/albums/n...xx/gmaxx20.jpg And used an old shoe lace as trunking for the RX wiring.... http://i115.photobucket.com/albums/n...xx/gmaxx21.jpg Theres a clearer pic of the trunking- remarkably effective. |
Thats it so far. I have some new 3.3 tie rods though- alot thicker than the older ones, and they came with the tall hollow balls so the bump-steer issue is sorted 'off the bat' (strange expression but makes perfect sense). Just waiting for my 2coolrc order of FLM bulks and Alloy hex adaptors, then I can order the Gmaxx suspension & single speed gearbox cover when their site reopens (and anything I like the look of while Im at it.) Cheers.

Nice job!!!! I would use some sort of high performance battery connection though, such as Dean's Ultra plugs.

You might want to see what new products they come out with before you order anything else...
|
I don't want to rain on your parade, but those piggy back shocks aren't all that great.
They're more show then go unfortunately. |

1. They were on sale, $79.99 for all 8 = bargain. 2. I have talked to alot of people on other forums and they are okay for general use, and since I dont plan on launching my new toy off a cliff in a hurry, it should be fine for my needs. I can always stiffen them up and play with the oil/ spring settings so we'll see how it goes. Cheers. |
Nice man keep us up to date
|
Awesome conversion man!
Heading the right way for sure!! you could set for 4 shocks, saved some weight. With the right batteries, that hvmaxx is a rocket. (if you manage to keep the truck light) 4S lipo would make it fast. the power from a brushless setup comes from the batteries, so if you use poor batteries, the speed will be poor. and the batteries you are using are most likely budget batteries. their internal resistance is high, meaning their voltage drops under the slightest loads. What arms are you planning on using? aluminum or plastic? Nice shell, looks very racy.. |

Lookin good suicideneil!

Very nice. Do you plan on bashing or racing?
|
Neither as-such. In my lovely little town there are very very few people with Rc vehicles of any kind, so there's no community like that. I just like to go down the local park and drive up and down, fast. With the Gmaxx though it does kinda lend itself to both bashing and racing, so theres no reason why I cant build a small-ish ramp and do stuff like jumps, powerslides and back-flips (practice will be required though). I have the RPM wear plates so they should protect the shiney underside fom the worst of my driving- will have to see if I can find a centre skid that fits the gmaxx chassis.
|
great g-max!!!!!!!!!!!!!!!!!!
some questions : -what gearing are you using? -where have you fond the fan for the hv-maxx? |
Most HV's come with the fan, otherwise, you can find them on tower quite easily...or, any 5v fan would work as long as the width and stuff is compatible. They are almost to the 40mm i think maybe a tad smaller.
|
Nice G-Maxx Project! Keep the pictures coming!
|
Thanks, & I will when I get more parts.
yep, the fan came with the Hvmaxx, but it can be found here: http://www2.towerhobbies.com/cgi-bin...?&I=LXJUR6&P=M Its a bit expensive at 21 bucks, but it does come with a mounting bracket and lead that plugs straight into the esc. It is also a tiny bit smaller than 40mm, which means a pc fan would need a custom mount made and a power supply- tap into the battery wires or something.... As for gearing- at the moment its still locked into first and running 13/66. This will very likely change pretty quickly once Im up and running, but i would be greatful of suggestions for gearing; say 11lb gmaxx running hvmaxx and 14.4v-? |
nice, keep it up!;)
|
cool but i told of the fan who's on the motor:018:

http://cgi.ebay.co.uk/Gunmetal-alloy...QQcmdZViewItem Mine doesnt really do much cooling, more-over it just looks cool. But I have plans..... |
Ha-ha, I just had some great news! No, my 2coolrc order hasnt turned up yet- I just sent them an email though....
Long long ago I ordered some punisher shafts from RC4WD, and about 5 seconds after using them for the first time they broke (uj exploded- well documented elsewhere). So I contacted them and they said they would send me out a newer version, free of charge. So I waited, and waited, and waited and nothing came so I kept contacting them and they kept saying 'couple weeks'. After months of waiting I was told they were on their way..... and still nothing. So I just contacted them again and clearly stated the whole problem/situaition & that I dont have a TXt-1 anymore, so could I have a refund as the shafts must have been lost in transit. To my suprise not 5 minutes later I got the full $79.98 refunded- result! So that will be going towards some FLM shock towers or something else nice and shiney me thinks.... |
that's the way to handle stuff!;)
|
Looking good so far everything is sweell other then the piggy backs

AS far as gearing with the HV, I was thinking that 72/13 would be good, but that depends on the HV you have, maybe BP can chime in on the gearing you should use. Also, I would get the single speed if you haven't already....

If it's the HV I think it is, they recommend gearing for 32 pitch at 70/12 and 72/11 I believe, somewhere around there. And yes, it's low, but it's due to the temps these run at.
|
Hmm, fair enough then. I'll start at 72/11 and take it from there. Thats the thing I love about the Emaxx tranny design- so easy to change gearing in the field without the need to dismantle half your truck, unlike when I had it in the TXT-1..... if anything came loose it was half an hour to fix it up & get running again. I love my Gmaxx....

Yep, you're quite right. I just got the box down from the loft and had a check- forgot what it says but I'll have another look and follow that as a guide. I forget that the emaxx drive line has a higher overall ratio than the TXT-1, hence why the 11/72 sounded a bit low to me, but then it has fewer reductions in the diff- its all groovy. Havent received a reply to my email that I sent 2coolrc so they will be getting another stern one, other wise they'll be in trouble...

I already do use a fan on the esc, but it doesnt really do an awful lot, so I may construct something myself abit better- that said the esc never used to get *that* hot in the TXT-1 setup, so hopefully it will be okay. I do like the HVmaxx system, it is nice and simple to just drop in on many trucks, though I wont be changing it for something better for a while- I've spent all my "disposable income" on the gmaxx, and there are more parts to order yet.

To me, this is poor. I would send another email tomorrow to verify that it shipped.
This is why Mike is a WIN WIN. Because he would at least tell you that it has not come in yet....after a month for sure. |
I dunno about another email, maybe a horse's head or small explosive device. Unfortunately these things happen fro time to time- normally I have no real problems with ordering stuff online (overseas or otherwise). My luck seems to have run out though.... hehehe. Nevermind.
