Ok so pretty much everything came in :yipi: more pics to come but here is a teaser

Question about gearing. The motor is a 7xl and have a mod 1 strobe setup. What pinion should i use? Thanks agian for all the help.

Nice. Not sure about the gearing but I'd change out those stick packs to at least some SXS or even better LiPo.

The plan is to get some lipo packs soon. I wanted to get a rough weight on the truck with the nimh cells in.

One other question is that the Feigao 7xl i have dosent have a flat spot on the motor shaft. I was wondering what the normal procedure is to make a spot or if there is something else i should do?

I used a dremel diamond cutting disk mounted on a drill, the flat spot is pretty uneven but it works for me.

Any suggestions on gearing?

With those nimh packs, I would say to use a 15t pinion, which will give you around 35mph. Much more and the batteries will not be able to keep up.

With good lipos, you could go up to a 17t, and do 40mph or so.

Lipos and BEC Came in today will get some pics up tonight.

What are using for the ESC mount hanging off the motor plate? Is that home-grown or something commercial?

Looks good ;)

Its homegrown:lol:, i leveled it out, but its mearly a peice of right angle aluminum and a small sheet attached to that. The only problem im facing is the gearcover. Im running a strobe slipper and the screws that are holding gear are rubbing on the stock cover. Im not worried so much about the gear but more of my wire getting tangled and cut. Any suggestions?

I run a strobe too. I cut the screws flush with the gear once mounted. No need for all that excess screw thread hanging off the end of the spur. Not to mention it saves you (albeit a small) amount of rotational mass.

I have the screws in the oppisite direction with the head showing on the side i can get to. I think what im going to do is use some standoffs that are metric thread in the trans mount.

Ok i fabbed something temp for the gear cover i couldnt wait to get this thing out! I wasnt expecting the amount of torque it has and the unreal top speed. When i first set it on the ground and took off it backfliped and ripped the revo wing i mounnted on the body right off! not a big deal but i wasnt expecting it at all!

Wiring is a bit of a mess, need to clean that up. I ended up ripping off the front bumper in the process of running also as i ran into the mailbox!:lol:

Reguardless this thing is AWSOME! and i want more now. Any suggestions on settings for the mamba to reduce the instant torque?

Increase punch control for sure, perhaps lower timing too if thats not already as low as it can go.

don't worry about the flat spot, I have never had a pinion slip off of the shaft due to the lack of a flat.

I think the timing was set to 10 when i looked at the mamba. Ill deffinatly turn the punch control on and see if that helps. It seemed to lurch and be jittery.
I see that now that i have had the pinion mounted and then taken it off.

One other major area of concern is getting the transmission to stay in gear. Unfourtenly i dont have the OEM linkage peice for the servo so i cant even stick it in there. I thought of getting the single speed but for bashing i dont see the need for the 74 dollars and that little weight. Any suggestions on this?

Thanks agian for all the help guys!

I just put a small cable tie or piece of wire (not electrical wire) through the little hole in the shifter shaft then wrap it around something near by, so the shaft stays pushed in (for second gear).

Ok so it broke, took it out this morning and didnt get but 30 secounds into it and i took a jump off the road bed and the steering linkage broke. Any good aftermarket ones?

Ok so i got a golden horizon steering kit and installed it this afternoon unfortunately no pics as the camera is dead. I took it out to a local warehouse facility and ran it in the dirt out back. I made rooster tails almost 6 feet long and 2 feet high. Ended the run with the pinion slipping off the shaft, any suggestions on this? I didnt think that lock tight was a good idea but let me know if this is usually the solution.

Im looking for a picture i thought i saved of some homemade wheelie bars. Anyone have anything that uses a shock setup or any suggestions on a premade one?

In answer to the singlespeed issue, you can just buy the coupler for $18 to lock it into 2nd gear, or you can bolt the dog-shifter to the 2nd gear.

I would suggest a flat spot on the motor shaft, and use a little blue threadloc to prevent it sliding off (just dab a little on the end of the shaft where the pinion and shaft meet).

As for a wheelie bar, you could use the rubbish traxxas version, or Swammie make one I think. NewEra also sell one or two I believe.

As far as the wheelie bar i will most likely fab something up as its needed.

Ive got to get some blue thread lock, necessary at this point as it seems im only able to get through a half a run and the pinion comes off.

Looking for a solution for the steering system. Im looking for the screws in the picture below.

Wondering if any of you know of a solution what is a hex head and possibly a stainless.

Anything?

I've never seen shoulder-type screws that small before, so you may be out of luck. My solution is/was to use an alloy version of the bellcranks that use different screws, and is altogether stronger & smoother. GPM, Integy, Powerline, Newera.. they all make good replacement bell cranks, complete with screws and bearings etc (drop in upgrade).

I got a Golden Horizon kit that is alloy but uses the stock screws, i was going to lock tight them but my concern is that the screws head will strip before the locktight comes out. Im going to go to a local hardware store and see what i can find. An idea i had was to use some small bushings.

Very very small bushings, but that would work I reckon.

I got a Golden Horizon kit that is alloy but uses the stock screws, i ended up using stock shocktower screws, slightly longer, and lock washer on the oppisite side, not completely tightened down.

For thoose of you who have the experience i was thinking of upgrading to a new maxx chassis and transmission, is this a good or bad idea?

It is much better than the old emaxx chassis, plus you can use the updated steering setup, which is also much better. Plus the chassis is longer, and that helps out stability. I have had great success with the stock traxxas wheelie bar. It does come undone at times, but I have not cracked one yet.

I just use a Collar to lock it in second. I have the shaft pulled out and the collar on the shaft to keep it from going back in.

If you have the shift fork pulled out that means it is in 1st. 2nd gear is closest to the motor plate side of the tranny.

Help.
 

I do believe that those stock shoulder screws for the steering linkage are the same screws used on the shock mounts. I just use titanium screws with aluminum tubing for collars. For the pinion gear blue loctite will help plus a flat spot on the shaft will lock it in better. I also place heatshrink over the pinion/set-screw to keep it from comming out all the way in the event that it does come lose. You are going through what most of us experience with an RTR out of the box vehicle. It will keep on breaking parts until you take teh plunge and bulletproof your truck using mostly metal hopup parts. One of the strongest and cheapest versions for making this transition is the FLM gear sold here on RC Monster.:yes:

I dont get why people just dont put the MM were the stock ESC goes? Down on the chassis.

I didnt but it there due to the wiring not fitting and i didnt want to add the length to the motor or the controller. I was easy enough as the 2 peice of aluminum are thing i had laying around.

Any suggestions on bulkheads? Is there an aluminum diff case that fits stock bulks but fits 1/8 hybrid setup?

^I’m a fan of hanging it off the dual motor mount, similar to the intention of the RCM ESC plate. Up off the chassis and bulks/towers, centralized and close to motor, and up high enough to get some decent air-flow from a vented body.

Ya the airflow is good but its more vunerable.

You have two options:

Muggy diff modifcation

UE Ultralites

Thanks for the help i think for now im going to hold off and see what the next few weeks brings as the local track is opening. Most of the guys seem to be running a stock 1/10 scale brushless class but a few of us have MT's and i know id like to run my maxx and possibly a revo if i can put one together.
