Traxxas Summit Brushless Rockcrawling MMM

[RcZandMore]

Hi great video what do u have to do to drop it to low gear is it new spur gear or wht? please reply thanks

[MrFlippychris]

was gonna get a summit and mamba it but just a question how is the car for crawling and mostly use with it and what system should i use for it thinking of useing a tekin rx8

[wilsontyler6565]

have you upgraded to the hobbywing sensored motor yet? if so how do you have it set up with all the settings? or how would you to get the best of both worlds of speed and long engine life?

[Ltally8228]

I looked through the comments and I didn't find this question so if I repeat it I apologize. Now do you have the mamba brushless speed control on it as well or can you use a different speed controller? And also on changing out from the titian 775 motor, because the mamba is bigger did you have to make any other adjustments on installing it or was it relatively easy? Would be much help thank you! Very cool video!!!

[RCJunky100]

@Ltally8228 The Castle 2200 motor is actually physically smaller than the Titan 775. The motor mount on the Summit will accept either motor however.

To mount the Mamba Monster speed control unit you'll probably want to get the Traxxas pt#5626 ESC mounting plate from a Brushless E-Revo. It will bolt the unit directly to your chassis. Hope that helps.

[wilsontyler6565]

hey man. im a newB to electric. i am going to be buying the summit and i looked over a lot of summits and yours is my fav so im going to ask what you recomend to me. motor? gears spur and pinion? batteries? and the sensor thing you were talking about?

thank you very much man

[RCJunky100]

@wilsontyler6565 If money's no object, get a 1:8 hybrid (sensored/sensorless) system for the best of both worlds (Tekin is good). Pinion/spur size will depend on what your motor's KV rating is however.

I still get plenty of enjoyment from my MMM/2200 setup, so you may not need to go broke with it. I cannot say if Castle ever fixed the throttle control bug with their later firmwares though (been out of the loop for awhile). V1.20 works so I've just continued to stick with it. :-)

[wilsontyler6565]

@RCJunky100 ok money is and an object lol so what exactly all do you have then i think ima just buy everything the same not to be a copy cat but i want a badass summit and yours is it!

[wilsontyler6565]

@RCJunky100 hey also what are good parts to upgrade that brake with the power and everything? axels? good improvements? thanks for your time

[CnRDirt]

3 rc cars I want really bad, traxxas summit, traxxas slash 4x4, and axial scx10 honcho

[MrMeowBox]

That rattle noise doesn't sound so good lol, any gears stripped?

[RCJunky100]

@MrMeowBox No, just the motor that makes the noise. Completely harmless.

[LiveWire50183]

what gearing are you using in the speed runs at the beginning?

[RCJunky100]

@LiveWire50183 18T pinion / 68T spur (entire video)

[Autophysn]

This thing is RIDONKULOUS!!! I am so saving up for one. My slash 4x4 is great, but.......

[SummitTraxxas]

@Autophysn you totally should!!

I have one and I love it!!!

I totally decked it out by putting machine guns and a grenade launcher on mine!!

Fake of course!!

But I use it in my Films and use movie Magic to add in muzzle flares and explosions!!!!

[SSSNJBJ]

[Bakkefication]

What does sensorless/sensor mean?

[RCJunky100]

@Bakkefication Means the ESC uses a separate sensor on the motor to detect it's rotor position.

Benefit is it's smoother/quieter at a standstill or if the motor is turning very slow.

Drawbacks are added cost and complexity (and less available top-end power on non-hybrid setups).

[DentonRCdriver]

Good job on the video and driving.

[RCJunky100]

@DentonRCdriver Thanks! :)

[niceNcrispy83]

Of course now you can use sensored brushless motors and be able to crawl without the cogging which you hear in this video, plus still go stuper fast :) I'm going to upgrade my summit with the new hobbywing 150a sensored brushless 1/8th motor soon.

[TheCANhunter]

lock your diffs when crawling!

[chrisvass98]

great vid!

[animatorSimen]

Cool video:)

@FreDCoDTrX is because with a brushed you'll get current to the axle? As the opposite motor is a b-less, which make the motors spin by the electromagnets?

[RCJunky100]

@animatorSimen I think FreDCoDTrX's info may be from old times.

Brushless systems have come a long way since their early days. A modern sensored system can work every bit as well as any brushed motor (and then some), and without the clatter noise such as what's audible here. Brushless motors typically have more torque than brushed due to lower resistance in the motor's stationary stator winding, and stronger neodymium rotor magnets.

[FreDCoDTrX]

@animatorSimen Brushless is the running, currently 2pole. Brushed is 5 pole

[MrRaymond947]

Ha thats cool

[kyrkbymannen]

Did you change pinion between speed run and crawling?

[RCJunky100]

@kyrkbymannen No, same pinion & spur for both (18T/68T)

[zfreeman55]

great vid. i was wondering if a brushless could also crawl in the summit. also nice crawling spot.

[pierredamata1]

2200kv?

[ysr50fan]

@pierredamata1 yes sir

[Tbomb187]

Wicked fast Truck, very nice man

[FreDCoDTrX]

Brushed=More torque to crawl and climb



[elitecamaroz28]

@FreDCoDTrX Brushless has more torque than brushed.

[MultiTIM1998]

at 0:6 theres a sqirrel

[NoLabelApparel]

I'm unclear and it doesn't seem to be fully/clearly addressed yet in this post- is the clicking we consistently hear from slipper clutch of some kind, or is that from something else? Very nice video, nice job, and thanks!

[RCJunky100]

@NoLabelApparel The clicking noise comes from the motor itself, as explained about 12 posts earlier

Thank you. :-)

[PaganWitchDoctor]

Is the rattling caused by the dif slipping?

[XXXTITEXXX]

hey man nice video. can you please tell me which springs do u use or how much preloaded they are.Also is there any any weight added to the front so that it doenst flip around? I have preloaded mine a little bit because at some spots the chassis was hitting the ground but now it flips easily

[RCJunky100]

@XXXTITEXXX I have Traxxas "Purple" springs all 4 corners. Preload is set for about 1½" of sag. No weight added to it, but lowering the exocage body closer to the chassis helps some (requires trimming the front body posts for rocker arm clearance). I also put Revo bumper mounts on to match them with the lowered body.

[XXXTITEXXX]

@RCJunky100 ok man, thanks for the reply

[Blakester569]

what batteries are you running?

[RCJunky100]

@Blakester569 2× 3-cell 5000mAh 40C Lithium Polymer packs in series (6s) for speed running, or parallel (3s) for crawling/hiking around in the hills with it.

[Blakester569]

@RCJunky100 how to you run the in series

[RCJunky100]

@Blakester569 Google "RC car battery series adapter". It's a Y-harness that connects one 11.1V battery into the other to make 22.2 volts.

[Blakester569]

@RCJunky100 so you double the volts i understand

[hobby0rc]

Nice video! is it a 2 pole motor?

[RCJunky100]

@hobby0rc Its a Neu-Castle 2200KV motor. Pretty sure it's 4-pole but I'd have to look that one up to be 100% sure.

[MrRctechno]

2 questions first do I still have the 2 gears and do they work just as good. And if you start slow and graduly pick up speed then at like 3/4 throtle you pin it will it flip?

[RCJunky100]

@MrRctechno Oh yeah, It'll rear up if you pin it from anything less than full throttle (and that's if you can get all the way up to full before the car is long out of sight! lol).

Yes, the two speeds work the same as before.

[170turbo]

Whats that horrible grinding noise? Like the gears stripping...

[RCJunky100]

@170turbo It's the motor chattering (cogging). Just the nature of a sensorless system if there isn't any movement in either direction (the motor has to spin before the ESC can determine it's rotor position). Advance the throttle a bit so the car starts moving and the chatter immediately stops.

[roadrunnersrock57]

how fast is that going, please let me know Thanks

[RCJunky100]

@roadrunnersrock57 I did not have a speed gun or GPS with me that day... I would guess around 45-50MPH based on past experience.

[Daniel160497]

the wheelie bar you have used in this video is from which car?

[RCJunky100]

@Daniel160497 It's a Traxxas wheelie bar pt# 5472 (Revo / E-Revo / Summit).

[Daniel160497]

he remains waterproof with mamba monster?

[RCJunky100]

@Daniel160497 I've been told the Mamba is water resistant or "splash proof" (it does have a conformal silicone coating sealing the circuit boards), however I haven't actually tried testing it beyond a little snow running (no desire to deal with disassembling the transmission and diffs to get water out of them if it's submerged)

[fillopygeesi]

DID YOU WEIGHT THE FRONT END

[RCJunky100]

@fillopygeesi No. I did lower the body down though (also swapped to Revo bumper mounts to match), which lowers the CoG so it doesn't roll over quite as easy.

[jawbonedoc]

Hey how do I revert back to version 1.2? Just got my Summit and Mamba Monster. Your truck is sick. The initial speed runs are what convinced me to put one on my Summit lol

[RCJunky100]

@jawbonedoc Hook the Castle Link USB interface between your ESC's servo cable and your PC, then select v1.20 on the firmware tab in the Castle Link software and upload it to your ESC (it will also tell you what firmware version is currently on your ESC beforehand).

Hope that helps, and thanks :-)

[todbuh]

best part at begining when squirrel runs for tree! great video.

[zaviac778]

I'm surprised it goes so smoothly.

[Bigbbiker]

do you have a wheelie bar on it?

[RCJunky100]

@Bigbbiker Yes, I have the Traxxas wheelie bar that comes with it's own quick-release mount

[dylan001367]

wow that thing has power

[MCGYVERTECH]

That is one wicked crawl machine, does Castle Creations make a gearbox for my Jeep? LOL. I suppose the ratcheting noise we here is the torque transfer mechanism, so to speak, shifting power to the tire with the most resistance, correct?

[discusdog]

@MCGYVERTECH That sounds like cogging to me but doesn't seem too bad though

[RCJunky100]

@discusdog Yes the noise is the motor. The extra traction comes from the diff lockers that work like little ARB lockers, just servo-actuated via the radio instead of by air lol.

[discusdog]

@RCJunky100 I have a summit as well.I love this truck

[Dubz0408]

@discusdog i suggest a sensored setup to get rid of the cogging and reduce the vibration that the cogging or the motor causes.

[philin2222]

awsome dude did you tape te tires

[RCJunky100]

@philin2222

I cut rubber strips from a bicycle inner tube and bonded them inside the tires to give the tread area better support without affecting the tire's flexibility for crawling. It reduces tire expansion at speed to some degree though it doesn't completely eliminate it like taping would. Thanks for asking.

[philin2222]

@RCJunky100 cool good idea that is one awsome summit you got there nice job thanks for replying :)
