Well i have come over to the dark side, this is my first attempt at a moa. Here is what i have so far.

Mann hard 2nd and 3rd gears
Br00d 40t R/T motors
FXR
CC BEC 7.2v
Punk Dig
Hitec 7950th (ignore the jr8711)

Lunsford ti uppers
Rear lockouts (JeepinDoug)
Vp Dh procomps fronts w/ 2 bullets
Vp SLW V4 rear

Any advice or comments are more than welcome. Like i said this is my first moa, and i know very little about them. Thanks, Bill

Looks nice. Why didn't you use the shock mounts on the chassis?

The front mounts are Jeepindoug 6mm standoffs(just the ball part,not the spacer) ,the rear are the stock Losi standoffs . I have to get some more jeepindoug's for the rear."thumbsup"I ordered some 5mm's for the traxxas big bores then i can install them. I couldnt use the stock shock mounts they were too far inboard. The shock would hit the transmission cases.

Got some more done today, think she is ready for some real rocks. Made some practice panels, put Sedonas all the way around. She weighs in at 6.08lbs RTR. Guess i have to put her on a diet"thumbsup"

Awesome Build. I think I like that chassis better than most of the other bodyless I have seen. What brand are the bent rod ends on the upper chassis end of the links?

Thanks i really dig the Fastback chassis too, too bad it is no more:cry: I believe the rod ends are Axial 3mm. I just had a bunch of stuff i pieced the upper links together with.

Oh shit!!! Looks good Bill next Sunday should be nice lolol.

Damn work computer!! I can't see the pics, but it sounds solid. It is going to haul ass. 35turn with 14/13:shock::ror:.

Yea, its pretty fast, i was just telling tyler i might have to change the pinions. Or learn how to stay off the gas:twisted: Maybe ill try adjusting the DX3R throttle curve a little.

lookin good! i love that lathe, im going to have to do that eventualy:D

So I guess x-mas came early for you bill 300's, 35T motors, and some other goodies nice work. Good thing you didn't go wit the 55T motors, and your gonna love those 300's.

The truck looks really good, i like the panels. Nice to see another UGC MOA chassis come to life.

Very cool Bill "thumbsup" Glad to see you were able to get the shocks working...they are inboard quite a bit, but the XR-10 is built that way.

Hope Tyler is feeling better as the days go by "thumbsup"

ive built some zero bind shock blocks for this setup....we gotta stick together with these chassis.....ill pm you with pics and info so you can make some yourself...super easy......or ill make you some "thumbsup"

The shocks are a challenge with these axles, Ill work it out."thumbsup" Tyler is great, thanks for asking. You would never know 3 weeks ago he had neurosurgery. Modern medicine is amazing"thumbsup"

Pics and info would be great, thanks"thumbsup"

Thanks CO, i haven't had a chance to get my caps from Richard yet. But i plan on trying them this week"thumbsup"

I almost hate to look at this thing since I know I will never have one.:x Did you end up robbing you Fastback, or is it still in tact?

Looks awesome Bill! "thumbsup"

My ax10 fastback is a little wounded, took motor,steering servo ,rx , fxr, shocks, wheels/tires. Im probably gonna sell the axles and tranny, to help fund the Berg"thumbsup"

Rig looks great Bill"thumbsup"

We need to figure out a way to get the shocks inboard.

Thanks Richard, maybe get in some tuning this week at miramar?

Maybe, my rig in in pieces :lmao: Later in the week should be no issue. Weds or Thurs.

Pieces? What did you break now?:lmao:

VP tranny cases coming today, playing around with shocks, and I am having front motor issues as of Saturday, I need to tear it down.

Cool, let me know when you want to go? Ill probably get out tue for some rock time. Im really curious to see what its capable of to start with."thumbsup"

If I can get it together tonight and my front motor is not toast I am game to crawl tomorrow.

I crawled npb Friday and Saturday and with out John's compressor there I am willing to be my motor is full of sand. Everything else is...

I meant to check it out yesterday, but my back pain meds had me asleep ALL day.

i may buy those from ya "thumbsup" going the other way....rebuilding my fb sporty rig for those fun fill in nights

Wait in line sir. I may need his 300's (I sold mine to his son) for a FB sporty build :flipoff:

I was wondering when you were going to post this up. Now its time to prove yourself.

Im just hoping to bring it home Sunday, in one piece:lmao:

:flipoff:why play that card:lmao: i would not be worried about breaking that rig..just do your thing!!

Do I need to get hardened pins for the mann gears?
What pinions/motors are other people running? What track width (tire outside to outside) front and rear? Thanks for the help

45t 14/12.i think them pins are fine.350 up front 225 on the rear..

I am still running stock(drilled) gears and stock pins. Almost a year now with no problems. (knock, knock, knock)

But i have seen you and Richardgarrett56 both drive, you guys are smooth. I still have the "gas it, it will come out of there" attitude. But im trying to change my style"thumbsup"

Well finally got it out on some rocks for a shakedown run, got a few scratches on the axles"thumbsup"

Then a solder failure at the FXR and i puffed a battery
http://i946.photobucket.com/albums/a...RGBUILD081.jpg

Didnt get much time so hard to tell how the rig was doing. Got home and fixed the wire, and inverted the rear shocks(did the front yesterday)

http://i946.photobucket.com/albums/a...RGBUILD084.jpg

Looks good. Well? Do you like it?

Hell yes, i like it. Only got about 10 mins on the rocks today. I still need to learn the front AND rear digs"thumbsup" Im digging it:)

Boy are you lucky with that solder failure, 10 minutes on the rocks with a brand new rig, it coulda been on fire! How were the rock at Markam?

After a closer look at your pics, use a piece of 1/4" delrin rod to tie the shocks together, at least the fronts. I worry about breaking the front off the chassis with out it as the chassis was designed with a cross member in that spot.

Since we can't get new ones of we break them now, error on the side of caution. I have a bunch of 1/4" delrin rod if you are out to save you an order. Let me know and I will cut some for you tonight and bring it tomorrow along with your v2 CO caps for big bores.
