airplane system on a car.
 

Hello,

I want to add more channels to my crawler and ran into a budget problem.
a 4ch system is 300+ dollars.

I saw a plane 6 ch system that was about 50 dollars.

what problems will I run into when trying to fit this system to my crawler?
is there someway around those problems?

thanks,
Guy.

Make sure it's on 2.4GHz. The 72MHz band, by law, is for airplanes only.

If I'm not mistaken the throttle is typically different, no to little brakes-reverse with neutral all the way down instead of nearer center travel, holds position instead of springing to neutral. The different neutral can be an issue for calibrating to the ESC. Believe I've seen conversions discussed on some of the airplane sites.

The for your replys.

I'm sure it's 2.4.

The transmitter has 2 sticks. Each With a y and x axis. One springs back to the middle and One does not.

I planned to make the springy One for throttle/reverse and front steering. The non springy One is for rear steering and a winch. One of the two switches will be for lights and that leave me With one spare channel.

Do you guys see any problems that i shall encounter With this plan?

Im New to the rc hobby, So im Sorry if my question are a bit dumb.

Thx,
Guy.

stick radios have been used before for crawlers. i myself run my ax10 based crawler on a spektrum dx6i. right stick is throttle and front steering, left stick is rear steering, and i have 2 switches set up for the dig, one switch puts the back axle in neutral, the other locks the rear axle.

did you have to make any modifications in order for the system to work?
transmitter\reciever\esc\battery,anything?

or did it just plun-n-play?

thx,
Guy

its plug and play.

Aren't airplane escs designed with the idea that lots and lots of cooling airflow is always passing around the esc? You might want to hook up a fan. I suppose thay are also designed with the idea that they will be constantly at 1/2 throttle or above, so maybe a fan won't be necessary. Probably a good idea to check temps occassionally.

using an airplane esc for a surface vehicle is a whole different story (mainly with brakes), but I think the intentions here are to use an airplane radio with the rest of the normal crawler gear.

Yeah, I think you are right.

Just read the title hmm? :lol:

Eh, the thread title isn't all that clear. Although I agree the post is more so best I can tell.

Duh, I didn't think of using the channels differently.

I'm not a crawler guy but I could see the rear steer being held wherever perhaps being an advantage at least in some situations?

If your OK with opening up your transmitter (will probably void any warranty) You could see if you can attach a small spring to the opposite side of the throttle gimbal. That way it would return to center (both springs will have to be the same tenshion) when you release the gimbal.
