Motor upgrade advice X Maxx 8s TP Power

[VIX]

I opened the rear body little to reduce air drag under body, don’t know if if makes any difference... just fun to try everything in coming days...






All is just temporarily done to try...

I follow your build and a few others with the Xmaxx hoping to one day add to the collection. I have one of the Hitec tx's and would like some advice if your willing at a later date when I get around to actually setting this up.

Not my day again! planned to test the car in the evening, noticed the car not breaking normal and in reverse the car getting enormous torque did backwards wheelie and broke a tooth on the pinion.. at least it didn’t came off probably something in settings... I have another 30T pinion to replace it with and try again.. mod 1 seems weak, will replace them with mod 1.5 gears.

Installed new 30T pinion and was told this motor has to much torque to hold any pinion in place for this truck, shaft and pinion screw are not hard enough. Mesh probably caused the teeth issues... I try again and see, not sure it’s right but otherwise I use mod 1.5 and weld it together

will try a steel bar not to flip over, not ready yet.. I cut off the castle cover, like to see the motor ) and can add fans if needed. will try all soon again

I purchased and use pinions from https://www.sagacustomrc.com/store/p...ons_gears.html

The pinions use 2x grub screws.

Running 31/54 gearing, leopard 5892 1340kv, hw max5

[VIX]

The wheelie bar is finished, easy to remove after speed runs... had issues with speed control, no breaking and difficult to reverse, probably the reason I broke many gears. Now it’s re-programmed and ready ) test coming

I am wondering if the issue with stripped mod1 gears is related to chassis flex causing a divination in gear mesh.

I still vote on improper mesh. If I recall, he doesn’t really run his truck too hard. I think since we haven’t heard from him in a while the problem has been resolved.

True, i don't run it hard.. yet ) It might been the mesh. Now the mesh is done by a pro and red loctite. The torque is same, 25P50S to 30P45S, now 30P44S No difference, still wheelies at any speed! Speed run will show if the loctite can hold the pinion or not... if not, motor is to powerful ) only need good place to try... its not easy with this car, maybe the new wheelie bar helps )

Good luck. I’m interested

This has been a fantastic thread to read. I hope Brian at fastlanercs finds this thread! I have worked with him for nearly a year now and he is great! I wish my xmaxx was this clean looking! I have tried a 12s setup with an alienpower esc. I had the same problem with pinions. I ended up getting my drill and put a small dent in the motor shaft and then used red loctite. I haven't had any issues since. I can't wait to read or see how your xmaxx performs!

Any updates VIX?
I just purchased an xmaxx with the max 5 and a leopard motor, however I have a tp5670 in the garage also. I'm hoping to learn from your experiences.

[604Slash4x4]

Go with proline trencher tires and my recommendation is to put a max6 and increase the punch

Thank you! Yes he is great guy but very busy... Sorry for the long delay to present result, when I'm back home, will do it! )

Congrats! im not right person to give you good advice.. I think TP5670 is awesome, All day rc on youtube build his xmaxx with it and max5 ESC with upgraded fan etc, very powerful! think he uses 25P/50S, I recommend you to watch his video and advices. I have issues with pinion gear backing off, will test all and make a video and present the result. I see guys testing top speed on parking places... I can't reach top speed on football field, need long straight road to do this, thats the problem. Ps I'm not so good driver and can do it on a road with cars parked ))

Why downgrade to a Max6. And those bodies are off limits for conversation here, not to mention hideous. Better option is the new Proline Brute body.

Sounds good I'll look him up on YouTube. Good luck with the work on your RC.

[targeting]

I don't know what experience on Rc's you have...but you need to understand this...

With such a beast of motor and ESC...you need a front wing or some oldschool "heavy weight" on the nose of the x-maxx.

Problem solved of wheeling...it will no wheelie! Period!

See this 2 video that explains the need for a front wing...

I know it's not a Traxxas RC but i am helping this brother to keep is X-Maxx undercontrol.
I have several overpowered Rc's and i am on the RC speed game for about 10years. No rookie but still learing everyday...

One basic rule for not wheeling is either front wing or some heavy "iron" on the nose!

https://youtu.be/DWu47GSbz6M?list=PL...KI4-n30p39gYTW
-No front wing!

https://youtu.be/dgV36_QYwHA?list=PL...KI4-n30p39gYTW
-With front wing!

Big diference?

As for bashing with front wing...well "make" your own conclusions...

A good way to put a front wing is to screw a piece of plastic or metal on the front bulkhead and stick it out to the front and screw a wing into it.... easy stuff!

[VIX]

Installed green Traxxas steering rods and Atomikrc parts for the shocks, not happy with the color, light green and doesn’t match Traxxas parts. Well, shipping cost was more then the parts, guess I keep them or replace all shocks later. Integy suspension conversion kit and Integy alloy brake set on the way i hesitated between green and silver, decided silver is better in the long run, scratches don’t looks so bad etc and if I change body to PL brute force later... will test the car direct after all installed, hopefully more stable in high speed

Few pics in the evening:

Thanks for putting the atomic stuff on your ride. I was tempted but was afraid it wouldn’t match. You’ve confirmed my fear. Traxxas makes green, and black aluminum shock caps as well that would look better. I’ll be getting the PL body shortly and will beat on it hard to see if it’s worth the price. Let me know how the steering rods hold up in a crash. Wonder if the HR would be better. Glad to see you can’t leave your ride alone.

[LibertyMKiii]

What do you think about the quality of those shock travel limiter straps? I'm thinking of getting some...

-Liberty

[Gripdog7205]

So I got disgusted with how clean your truck is and tore mine down and detailed it for a couple hours. Time well spent.

[VIX]

[QUOTE=LibertyMKiii;6469967]What do you think about the quality of those shock travel limiter straps? I'm thinking of getting some...

well, first the screws in the set are to short and need to be replaced. I would say kind of useless, probably only to be used for speed runs not to flip using oversized motor )

Your welcome ) I agree Traxxas shock caps would been right choice. The rods feel much better then stock, also will get Integy rods later. I look forward to hear your opinion on PL body later, it looks very nice and well made.

[VIX]

Few better pics Incase anyone consider buying Atomik parts in green.. even if they don’t match, looks better in alu the plastic, I probably replace them with Traxxas.




Body is under construction... will cover holes with carbon plates to let air out

More mods coming )

Body ordered. I’ll be very particular about decals, since you can’t paint it

+1, also ordered PL body.. + took your advice, ordered Traxxas shock caps etc in green, will replace Atomic.

Did little makeup with Liquid chrome pencil, over shock caps ) only painted once, twice is better and washing has not been a problem so far.., need 1mm pencil to finish edges (ordered) and the Max5 fan, love these pencils

not ready yet and dark pics:




Hopefully all Integy parts coming this week and can test it

[VIX]

All parts didn’t arrive yet, changed the shock caps to Traxxas... will decide if I use the Integy steering arms or keep the green when the suspension set etc comes, it’s stuck in custom...

Installed Integy parts, Silver looks amazing! Very high quality! Only issue was the brake disc, tried to modify them to fit, nope! I will need longer stub axles, missing few millimeters!

Few more, Integy arms has two settings, feels little higher

Fixing all bearings and grease before I will test the car... not sure what grease to use here, marine grease or anyone have better option?

Ordered these to try and new cover, can’t find green cover that match Traxxas alu.




New cover:

Car is done and ready to roll out ) received Proline brute armor body today, very cool! Will modify it little for more air cooling) Only all stickers must be cut out! All diffs greased and bearings, around the the housing cover to prevent water... I hope ) The axel boots, only used zip tie and super glue under the ends, perfect! Only clean them with alcohol first. Im totally sold on Kraken Vekta.5 LSE brushless, my next car with mgm and Lehner 3080! I regret i didn't use Lehner 3060 in Xmaxx with air cooling instead of TP5860. I saw resellers stop selling them, shaft issues and only warranty in China, not cool! Maybe the steel not hard enough to keep the pinion from backing off... I will test again ) before installing belt drive )
