Topic: Dual Sport RC? Is there such a thing?

[Shamb]

So now that i'm selling my REAL rig, even though it isn't sold yet i'm getting the itch for SOMETHING wheeling related so I may buy an RC crawler..

What I would really like is something dual sport in the sense that it will do 50+mph on the street or offroad but ALSO be able to crawl. Do they make RC's capable of this?  I was reading a few of DTB's post's and found it interesting that RC's will actually hook up to your laptop to adjust throttle curve ect? 

I used to be big into RC's and had a fully built 4 wheel drive rally car with a .21 gas engine in it.. but it's been so many years i'm sure alot has changed since.

So clue me in!

Is there such a thing?  what's a safe price range to stay within?

Thanks,
Shamb

Nada?

I shall start the research!

If I find anything of interest I will post up.

I have wondering the same thing my self.

[jedrattle]

  Nothing like that exists. The problem (imo) is the type of suspension, lockers, and gearing needed to make it work. It would need a selectable locker up front or it won't turn well at high speeds. That are no selectable lockers for an R/C. The suspension stuff would be crazy to try and make work well in all situations.  I am going to build a trail rig that would be a little bit of everything but just not that fast. RC4WD makes 2 and 3 speed trannys. That might be a way to get some top end but how much is the question. The problem with that is, just like in real life the more you add to make it work, the heavier it gets. And that's not good either.

[Shamb [OP]]

what about a one piece solid axle?  is that feaseable?

then you woudn't have to worry about lockers. Both tires turn all the time together.

I see your point with suspension though........ hhhmmm...

[jimbo74]

i think you can do it with a electric... liek the emaxx... they can be setup pretty sick.... and they have multi speed transmissions too....


i had a tmaxx, and i had a spool in the rear, that think still hualed but.... just didnt like me powersliding it, and would roll over @ speed sometimes... but i had an original that is narrower than the new er versions

[jedrattle]

  I have an Emax with a brushless setup.....it hauls ass!! But it is very heavy and without lockers it goes nowhere. What is fun about it, is that it's a wheelie machine!

I have thought about this as well Shamb....have you been looking on Rccrawler.com?

I think a brushless with the mamba max would be a slick set up...I just have a 65 turn lathe motor so my speed is really limited (also by the throttle curve, which IS easily adjustable) The only real problem I can see is the gearing would be too low to go real fast...you might have to get a larger pinion

[DTB]

Oh and there are also RC rock races now with scorpions....

Are you looking at Axials?

as far as price...look to spend about 5-700 bucks on parts to build a nice scorpion crawler

[Shamb [OP]]

Is this what your talking about DTB?

Also you bring up a good point. I suppose you could make a dual sport rig if you didn't mind swapping a few easly swapable parts like shocks and a smaller or larger gear off the main shaft for speed variance.

[Shamb [OP]]

in the RC world what's considered the "best"  rc crawler out right now?


Some of my fav's thus far. I still dont know much about what specifically to look for.. still in research mode.

As far as this site is concerned I have found this tid bit of info

quoted from yotee on the Axial AX10 thread

"the goat system w/brushless is Fin sick. enough wheel speed to roll it in the dirt burnin brodies! and crawls like it should"

The goat system isnt adjustable like the mamba max.....I would go for the mamba max and a brushless motor.....

but yes those are the ones shamb....I have a scorpion and I love it. The scorpion is probably the most popular "out-of-the-box" crawler and has tons of aftermarket support/parts....

If you want even better low speed control than a GOAT system and insane RPM, Brushed is the way to go actually... With a Cobalt Puller Motor. http://s273.photobucket.com/albums/jj217/mrjoker619/?action=view&current=crawling005.flv

thats what my axiel does with the goat set up and has really good throttle control so you copuld crawl as well....its a freak wheelie machine

acts jut like the brushless system i have with the same wheel speed, cept i have the crawler pinion gear in and the puller brushed motor has the larger go fast pinion gear. i'd get even more wheel speed with that pinion gear. the problem with the puller motors that i don't like is you normally have to cut/weaken the side of your chassis to fit the motor. it is really just down to what you like, some hate brushless motors, and some don't like brushed motors. kinda like the toyota jeep thing. when i had the brushed motors they were kinda "lumpy?" at LOW rpm's where the goat is smooth at any rpm and crawls with all of it's torgue at all rpms. i do not notice where my son's brushed motor will crawl any slower than my brushles. mind you my brushless doesn't have the torque to destroy every part of the crawler like the 7 turn cobalt can (just most of it). i think i will have to buy my son the puller motor and get back to you guys with an actual side by side comparo.

here is a better vid of the cobalt puller in a rock racer, 2 speed trannie though

edit
shamb, are you sacramento area or san jose? i can't remember. if you are in sacramento you can come by and check out the axial's in pearson.


mike

edit again
as for dual sport, you may want to look into something like a built axial rock racer

 Sorry Shamb, I'm Gonna Hyjack Your Thread really Quick....

I Don't Fallow The RCCRAWLER Board Much, But I Have A Scorpion And Love It, I Bought The RTR Kit And Beleive It Or Not I CHOSE To Keep The Stock Motor Because I Prefer To Haul @$$ Up Everything LOL. And I Couldnt Help But Notice You Guys Talking About A Rock Racing Class For Scorpions....Any Info On This Would Be Great!!! Thanx!

i havn't seen any local to me but you are in socal and they have every thing there seriously check out the comp section at rccrawler.com or the regional west section.

a quick glance over there only gave me a rockcross event on floriduh i'm sure you could get a local thing together over there.

[RynothealbinO]

My thought on this concept of "dual sport" has been to build an E Maxx style crawler only out of a T Maxx.  Solid axles with a high travel heavy duty 4 or 3 link suspension.  Rear locked and front open or locked depending on what you want.  Keep the two speed and see if it is possible to gear the low lower.  This would let you still go 30 something or more, but also have a low gear that probably wouldn't truly crawl, but it would be low enough to let you claw and bash up whatever you wanted to.  Just a thought.

[yotee]

well i went and switched the motor pinion gear from a 14 tooth crawler gear to a 20 tooth go fast gear, and switched the radio/reciever to a spectrum dx3, among alot of other things on my crawler/rock racer. the end product is unbelievably cool. i went with a chrome edge chassies, goat system(still) removed all the green and polished the aluminum to match the chassis.

with the new radio/reciever it crawls slow and flawlesly, and launches off the ground with a blip of the throttle. i had glitching issues with the old radio/reciever because it was as cheap as it came(team associated rc 18 electronics).

i am starting a thread on rccrawler rite now asking for a comparo on the different moters asked about, and will be trying one of the puller motors on my son's crawlers.

[yotee]

the thread i started with the peeps who know what they are talking about.

i still plan on the puller for my son but unexpected money things came up this week that will push it back a few weeks.

[Shamb [OP]]

I'm near Sacramento,

I thought about a rock racer but do they have low crawl as well as fast?

or is it just fast all the time?

[yotee]

mine has what ever you want. it crawls flawlessly and will take off easily.

edit: i don't know how often you are in sac area but if you want to check out what i think is as close to dual sport as you can get then pm me here or pirate.

here is a link to another thread asking the good and bad of brushless and brushed

well the holms hobbies 7t cobalt motors are off of back order now, so i ordered one for myself today. i was talking to the guys at folsom lake today and they said that the cobalt puller should have a little more power than my goat brushless has so the goat is going in the boy's truck along with my 2 cell lipo. i'm gonna have to get a 3 cell lipo and a new speed controller for mine, not to mention a decent radio reciever for his because the novak would not work with the cheap radios for us. soon as i get them all up and running again i'll report back.


mike

[yotee]

well the results are in. identical trucks, batteries, pinion gears, spur gears, chassis blahh blahh. the only difference is speed controller, radio, and motor.
#1 has a goat system and brushless motor.
#2 has a fatuba controller, and a 7t holms hobbies cobalt puller motor.














































drag race-----------------------goat pulls out the win
batt life-------------------------goat pulls out the win
crawlability----------------------tie-no noticable differance at LOW low or high rpms


so there you have it. the goat brushless motor just seemed to win hands down, MUCH to the dissapointment of my son
