lightening emaxxs

[RC-Monster Mike]

A digital scale(I weighed most recently on HotnColds digital scale).

It really isn't overly difficult to get near 8 pounds with a brushless truck. If you fiigure the stock truck weighs 11 pounds, RTR it is fairly easy to get the weight down. you can save a pound in tires/wheels pretty easily, and another pound by using Lipo batteries and converting to the single speed conversion(and losing the extra servo). Already, the weight is under 9 pounds! Then, figure a Lehner basic xl weighs about as much as 1 titan, and the 9920 controller weighs less than the EVX, so you save another .5 pound, bringing the truck to less than 8.5 pounds. Then, drop another few ounces by removing the bumpers and switching to g-maxx skids. Voila!! An 8 pound e-maxx! The g-maxx chassis and extension adds an ounce or so back in, as do the cvds, but the g3 suspension(without the levers and using 4 shocks) brings this back into balance. Then, the UE VBS replaces the stock bulks/diffs with little change in weight, but a giant upgrade in durability. Not so hard to do, you see?

It is 2oz lighter than stock. I believe most of the ue stuff is heavier than stock, but a lot stroner. The titanium cvds/hinge pins/turnbucles are lighter - but not by much.

UE's weight to strength ratio his huge. You are right the cvds pins and buckles are lighter. If you don't have money for a gmaxx single speed conversion atleast take the first gear out and lock it into second. Are UE diffs lighter? They are defintily stronger. Replacing steel screws with aluminum screws will also lighten her up. But you run the risk of breaking screws.

i dont know how to get my truck lighter. i have tried so hard and its still over 10 pounds with only 12 cells . G-maxx CF chassis, 6 spider UE diffs, racer x, ga bulks, 40 series bowties and velo rims, all first gears removed, 8L on 12 cells and i will be at around 10 1/2 lbs. im thinking those new crime fighter tires will be really light. im almost to the point where i buy a revo and go brushless. any ideas on droping weight? mike, are you running those cut bowties on stock wheels? how do you get it that light? thanks guys

Two words: VBS and LiPos

Didn't you already post your maxx up for sale? Can't really back out now..

[RC-Monster Mike]

The GA bulks are very heavy. The VBS is very similar in weight to the stock diffs/bulks. Also, your truck is wearing bumpers and a wing, which is close to 1/2 pound. The 40 series tires may be a bit heavier than a modified bowtie or trinity Bokar(on better wheels), and the new crimefighters will be nice and light as well. The single speed tranny saves another couple ounces(especially including the servo). The Racer x suspension is only an ounce or so heavier than the stock suspension, so this is a worthwhile upgrade for sure. I also run the Lehner basic xl motor, which is around 4 or more ounces lighter than the Feidao "L". It all adds up, little by little. My truck is a little over 8 pounds, but it is closer to 8 pounds than 9 pounds. Also, even with 12 cells, I have 3/4 of a pound less weight in batteries alone. If you went to a lighter bulkhead(or VBS), lighter wheels and tires, Lipo batteries and removed the bumpers and wing, your truck would be way over a pound lighter and get longer runtimes with less stress on the parts. 10.5 pounds on a full aluminum race truck with all the trimmings isn't all that bad in the first place. You also have a receiver pack, which is almost a 1/4 pound of extra weight.

thanks mike,

im really short on cash, but i have some coming (a friend owes me) that will go into my truck. im gonna need a strobe, UBEC, im not gonna buy lipo...too much money for me. ill buy a bunch of 3300 6 cell packs. i may look into a Lehner motor too, but probley stay with the 8L. i will get some crime fighers and mount them to stock wheels to cut more weight. as long as i get below 10lbs ill be happy. thanks for your help guys

What wheels do you reccomend?

[squeeforever]

my truck is only 8 1/2 lbs. rtr with 12 cells. thats with heavy road rage tires and rpm claws rims. 40 series would make it lighter.

[RC-Monster Mike]

I just weigh two emaxxes on my postal scale-here is the results:

#1 - extended g-maxx w/raer x suspension and shocks, towerless vbs, bowtie tires on stock wheels, 18120 controller, basic xl motor - 8.75 pounds RTR with 14.8 Lipo 9 pounds RTR with 18.5v lipo.

#2 - G1 gmaxx with custom lower plate, g3 suspension, racer x shocks, basic xl motor, komodo tires on rpm titam wheels with 14.8v lipo - 7.75 pounds RTR!

[squeeforever]

i think with lipo and rims and tires i could have a 7 1/2 lbs. truck.

[RC-Monster Mike]

Without question a 7.5 pound truck could be done. Both my trucks are all aluminum with upgraded diffs and cvds. Stock diffs and driveshafts alone would reduce the weight quite a bit..

I wanted to buy that VBS system too, those things where out of stock, so i had to go for the FLM's.. I don't know what the weightdifference is between those and the VBS system. Got an idea Mike?

On that 7.75 lbs truck, you use 6/8 spider diffs as well?

[RC-Monster Mike]

The UE vbs is notieably lighter than the FLM combo bulk system. I don't know specifically, but the difference is a few ounces at least. The sub 8 pound truck uses maximizer diffs (or FLM-I don't remember which are in it) and proline(mip) cvds.

Where can I get the 40 Series or RPM rims from? Which are the light ones?
