Hi All,
My first post in this forum!

I would like to know if the M8 can do all the things as stated on the UTQ3.
Particularly on the ch3 manual steering part, not full left or right.

I would like to take my time to read the manuals, but Airtronics charges for the M8 manual.

So if anyone here owns both TXs, pls give me some comment cuz a frd is gonna sell me his used m8 cheap.

I am gonna use the TX for my TXT crawler.

AND THANKS!!! :-P

A M8 is not a very good crawler radio. I use one right now but i just have my 4wheel steering hooked up with a y harness and then have a winch on the front hooked up to the third channel.

the third channel on the M8 is hard to reach easily while you are driving. You basicly have to take your right hand off the steering wheel to turn the knob. and then it is still hard to recenter the rear wheels with that knob if you use the third channel for rear steering.

i would probably use the traxxas radio if you had to buy one.

The M-8 can steer the rear tires on the aux channel knob. Centering is sometimes difficult but it is easy once you get the hang of it. There really is no comparison between a cheap modified TQ3 and a high end M-8. I like the M-8 because I have 4+ vehicles using DSM/Spektrum receivers and it works well for all. I do not own the UTQ3 and I am sure it is a great crawling radio, but it is just not comparable to the M-8 in any way.

Thanks for the input.
Think i'll get a tq3 or utq3 soon.

As far as quality, FM and a 10 model memory, NO there is no comparision. I have the new Spektrum system also but i race RC's also. Most people aren't going to spend $150 plus dollars on a radio and then another $150 on the spectrum system.

But to go buy a radio just for crawling and you are standing 3 feet from the vehicle i feel you don't need such a high end radio for that. Your not going to have to worry about glitches probably.

There is not a better radio on the market than the M8, but it is still not the BEST radio for crawling. Will it work? YES.

Agreed.

The UTQ3 is not a cheap modmodified TQ3. It has been modified for proportional rear steering and mixing.

Your post should read.

They have modified a cheap TQ3 to have proportional rear steering and mixing.

A few crawlers on this site that I have talked to find very little need for the extra bells and whistles of the UTQ3. There is no argument that a TQ3 is a throw away radio. I have 4 just lying around that came with Traxxas kits. I have nothing against what the UTQ3 is. It is just that for $60.00 more you could have a top of the line digitally proportioned multi vehicle memory transmitter. R/C is a diversified hobby and what good is a UTQ3 if you switch interests from crawling to touring car racing? If you are going to spend good money on a transmitter get the best most diversified easy to use best fitting one you can. This is just my humble opinion.

Hmm... now m8 seems appealing to me.

Does it have ch3 mixing? It doesnt state in the website. Just says servo reverse.
Dunno for all or independant channel.. ??
I mean for 4ws normal to crab-walk on demand. Can it do that?

Thanks for help.

The M-8 does not have a switch. In order to crab walk you must turn the rear wheels in the direction you want to go then turn the front wheels in the same direction. Basically mixing is being able to accomplish many tasks at once, which the the M-8 does do. The easiiest radio to accomplish this task may be the UTQ3, but my ppoint was to consider the future.

I was thinking aboutmodifing aTQ3 with switch just in case I am on unstable ground I do not have to worry about breaking my expensive radio. You can buy a TQ3 on e-bay for less than $25.00 and a switch for $5.00 and within a half hour you would have an expendable crawler radio.

Actualy that's not 100% acurate,

It's modified so that you have a selection between manual (the togel switch set-up everyone is using now) and a "mixxing" mode that is just like running a y-harness but gives you the ability to adjust the trim settings and servo reversing seperately according to the site.

It would be nice to have independent, proportional rear wheel stearing though

Oro? Being more specific...
On a M8, if y front servo goes to ch1, rear servo goes to ch3, will I be able to do 4ws?
To me, mixing meaning I can programme ch3 to do things when I control ch1 with the normal steering wheel.

I've studied the TQ3 and drawn up a schematic of how it works.

I think with a very simple circuit board mod you could have fully proportional rear steer using another pot.

Its been done. He called it the TQ6 or something...

I see no reason to run anything other than the TQ3 with a switch on it. Simple, cheap and effective

MANTIS · 03-21-2005, 02:23 PM

Maybe I ought to post to clarify things
I am the one who designed the UTQ3.
I got the idea for this radio when my partner in clodmodracing, blade, was letting me run his crawler. He had wired a pot to run the back wheels. It took alot of time and much needed brainpower to run. So I came up with the UTQ3 after several prototypes.
About the circuitry:
I guess first of all, the nature of this mod is not adding a switch or pot to the existing wiring. There are about ten to twelve new components that do the job, including some integrated circuitry. It would be a challenge to remove what is done to these radios. If it were simple, I would sell kits as well.
About operation:
I crawl and I desinged this to work for crawlers. My favorite way to run the radio is to have the channels mixing (mimicing may be a better word). This way it drived like a 4WS truck. Then when I'm crawling with my front wheels pointing left and need to reorient the back wheels, I will flip the thimb switch and the back wheels will also steer left. I will also flip the switch back and forth, in order to wiggle the back wheels to find something to grab. The switching between normal and crabwalk steering quickly is the best. Think about that next time you crawl.
Now in manual mode:
THe operation is just like the cheap hack with the toggle switch. I included it because alot of guys like that option. The switch that is used though is a center return type, so it is also really quick. It is also easy to run the throttle, steer and rear steer at the same time with a little practice.
I have a couple on ebay right now if you a curious. I plan on starting another auction in a couple weeks if you miss that one.
Please post any question you may have and I will do my best to answer.
