Things that put me off the quad... they are slow. the front suspension hardly works and constantly changes camber. the rear suspension is way to hard, the COG is way to high, gearing is useless and there motors are nothing to rave about. my 26cc losi has the same power as a 49cc quad... go figger?

Of course, if you just stick a couple of servos straight on to it, it won't be much fun.

As mentioned above the suspension won't work as it's rated to carry a person.
You'll be best off stripping all the componenets off it and building a new frame, sitting the motor lower and changing the suspension.

Yes, it can be done.
http://www.rcuniverse.com/forum/m_9445744/tm.htm
Yes, it's been done before so you can do it. see above
As for advice, if you want to have fun with it, just save up and buy one, but if you want to build one, then have a go at it.

I can understand that completley. but using a $300-$400 extremly dodgy chinese quad as a platform is not a smart way of doing it. & its a expensive way if u plan to use only the motor....

U dont under stand that the quads chain drive reall limits the way the rear suspension can actuate. Ever had a close look how they work?
Well I have... they only go up and down, and if one wheel goes up so does the other...

I wanted to build one with the one u use to have, it was the only reson I bought it. but after looking at it & the cost involved in the 1/4 servos & all the custom work just to get the steering working, dident seem worth it... there is a few on youtube but they are so slow.....

Status: offline 		you guys have brought several issues about using quads. seems like the biggest problem seems to be with the supension and the center of gravity. I will have to rethink this project and come up with something better.

I do understand how the suspension works.
I understand how chain drive works.

I also understand that a home made RC car should never be compared to a factory produced, engineered large scale RC vehicle.
(Unless it's built by Vassilis of course )


It doesn't have to cost a lot.
Hell, have you seen what some people spend on their Bajas?
10's of thousands of dollars putting factory made parts on to a factory made car to make it "different".

The purpose of building your own, or indeed converting something non-RC to make it RC isn't to make it faster or better or even equal to something available to buy from the shops.
It's about having fun.
If your first thoughts are about money and handling then clearly, building your own RC car isn't for you.

I've built a couple of home made RC cars from scratch using weedwacker motors, scrap aluminium and whatever I could find to do the job.
They are absolute rubbish compared to a "real" rc car, and a waste of time according to a lot of all-knowing people on the internet.
Slow, heavy, no suspension, but I had fun building them and the feeling I got when I put it on the ground for the first time and it moves, can't be described.

Status: offline 		Not sure if you're looking for speed or a wow factor but I built a brushless power wheel for my nephews and its a head turner when we're at the park. Besides that, I don't know of many large scales that can tow around a 50lb kid. If that's your goal, I'd go for it. I if you're looking to bash, then don't.

Status: offline 		Those chinese quads are only good for donating parts like front hubs and brakes. Eveything else is useless. If you happen to buy a used one that has broke down for less than 50 bucks then go for it. Otherwize leave those machines alone. Your better off building things yourself.

Sorry bud we are going to have to agree to disagree. Why build

absolute rubbish
???? why not put the time & thought into making something great? seriously if u really like building why not build static models?? or put the time into making something good.
I had a 49cc quad. even covered in in Traxxas stickers for a laugh. Check the rustler thread, I even posted all about how i planed to convert it to a r/c car....
wanna know why i diden, not because of cost, not because i couldent. it just was not worth it. I have a very high expectation of my self and the things i make. and i dident see it fiting into my expectations. Simple. each to there own.

Last thing u would predict that the cost of converting a quad to R/C would be around $600.... for $700 u could get a HPI Baja clone..

IMO the OP would be better off building his own tube chassis and custom suspension. and put a reliable motor in it. use the drive train from existing r/c cars unless he has a machine shop.. hey if I had lots of cash i would build a 110cc 1/4 SCT with a 4 speed gear box... now a 110cc chinese quad would be worth converting... u guys seen them with the power wheels bodies???
