hi guys, i just pm'd mike to order a lehner 1950/8 and a bk 12020. in a week or 2 i will order the g2r roller. what are the necessities for this truck to become really tough and precise on the track? would i be better off buying the gmaxx tranny? i'm using a spektrum dx3 radio, so what servo is recommended? what tires and wheels? what body will fit the g2r? what pinion? as you can see i need lots of help and i can't wait to get started on this project. i know everyone will give me great advice, i just have to be patient. thanks, carl.:004:

well lets see here.

as for necessities, p2 rockers are a must, small things like the aluminum hollow balls, aluminum rocker post (or titanium), titanium turnbuckles, and the traxxas aluminum pushrods are all good additions as well. oh, a wing is a MUST in my opinion. your truck will handle and jump much better. its not hard to make one work. a few washers, some long screws and a mbx 5 wing.

i would cetainly go for the gmaxx tranny and i would also spring for the flm half case, strobe slipper and a steel idler is a must. i would also go for a rc-monster heatsink/clamp. you wont be able to use the clamp part but it will certainly keep that expensive motor cool.

i would recommend a bluebird 660 if you want to save a bit of money. they are good servos, especially for the price. the hitec 645s are also good.

as for wheels and tires, i would go for the wabash rims and crimefighter tires. i have the wabash/crimes and the velocity/crimes and the velocities make it as wide as it is long. its a tad to wide for me.

as far as bodies, i like the crowd pleaser 2.0. its made for a revo although the g2r is a tad longer than a stocker, you should be fine.

im not to sure on the kv of the 1950/8 so i cant really recommend a pinion but that would also depend on the number of cells and if you run a strobe slipper.

i'm going to run lipo, everyones telling me 6 cells. i just don't fully understand series and parallel yet. i will be running a strobe slipper, when i find one. can someone help me out a little with choosing series or parallel? thanks for info squee, this truck is finally starting to coming together.

You'll be running 6 cells in series with that motor,2 3s packs in series.You could run 2 3s1p packs in series(22.2 volts),good high capacity packs with a high C rating,or you could run 2 3s2p packs in series(also 22.2 volts) ,twice the capacity and amp handling (but twice the size and weight too)
2 6s1p in parralel would be the same as 2 3s2p in series.confused? Check out Batfish's stickyhttp://www.rc-monster.com/forum/showthread.php?t=2250

Edit:aluminium diff cups would be a good idea.

do i need a 4mm or 5mm mod1 pinion for a 1950?

Gustav · 03.28.2006, 12:17 AM

5mm on the 1950.

tallyram · 03.28.2006, 12:29 AM

thank you! i know i should start gearing at 15/51, what other pinions should i get?

Gustav · 03.28.2006, 12:44 AM

It would take a 18/51 i would think,it's a fair amount of power there,just keep an eye on the temps,get yourself an I.R temp thingy if you haven't got one.For the track i'd try the 15 tooth.

tallyram · 03.28.2006, 12:57 AM

what servo would you recommend?

coolhandcountry · 03.28.2006, 07:53 AM

What tires you run and diffs? I run different gears depending on tires. For a set of like bowties or crimes the 18 works well. You could run a 20 on them as well. I run a 16 51 on the big joes. I have buggy diffs though.

Gustav · 03.28.2006, 02:07 PM

It's a g2r,i forgot about that,18/51 on 3.3:1 diffs is between 15/51 and 16/51 on your revo diffs,so i'd get a 15 and also maybe a slightly smaller pinion for the track,depending on what tyres you run.You could still maybe run 18/51 for some speed runs but this is higher than i was thinking before,i was thinking 3.3:1 but your diffs are higher ratio,2.85:1.

coolhandcountry · 03.28.2006, 03:22 PM

The best servo I have ran is the hitec 5955 tg. It is awesome servo.

tallyram · 03.28.2006, 03:39 PM

thanks coolhand, i'm getting one. btw, what kind of screws do i need for mounting the 1950 to the heavy duty traxxas motor mount, and where do i get them?

coolhandcountry · 03.28.2006, 04:04 PM

i use a 3 mm cap head screw. I am not sure on the length right off. I like a small washer on it to.
