Programming my dual 7XL's - RC-Monster Forums

JOHNNYMAXXIMA · **Programming my dual 7XL's -** 06.22.2006, 07:09 AM

Just got done programming my controllers for my dual 7XL setup. I programmed my first controller (the one that has the UBEC connected to it) with normal procedure of pulling the black and red jumpers then putting the red one back in when finished.
Now I did the same thing for the second controller and nothing happened. Then I remembered that the second one doesn't have the UBEC wired in to it so I Plugged the black jumper back in just to program it. Everything went fine so then I removed the black jumper and put the red one back in (not in the same spot as the black one of course).

Just want to make sure that that was the right procedure for the second controller. It seems to run just fine for the couple of minutes that I had it running in the garage but just want to make sure. I believe that is how I did it when I programmed my dual 9L's but can't remember for sure.
Thanks

Just got it running yesterday and have yet to drive it out in the street. The old dual 9L's ran 51mph so hoping to get a little bit more out of the 7XL's.
Here is an old pic of it http://www.rcpics.net/img/67700 it now has the 7XL's in place of those 9L's and two 5s LiPo's in place of the 28 NiMh's.
I need to quit spending money on this thing and spend some on some kind of movie program for my computer so I can down load the vids.

how come ONE brushless motor gets u upto like 45 mph and then adding another one only brings another 5-10 mph increase..!!!!!

You add 14 cells of more weight plus the weight of motor and extra esc. It takes power to push that weight.

dual motors will add torque more than top end the motors can still only spin up to the same RPM but you can add top end by gearing up

Exactly.

Jonny... any new pics of the dual setup. Just curious. I was thinking about trying it w/ 9Ls and 9920s. What controllers are you using. Any problems trying to get the 2 systems to perform equally? No fried motors or controllers or anything?

Nothing new jhautz. I've only run it once since I got it together and that was only for a few minutes until the front diff went south. My wife had a surgery and I've been taking care of her and my two little ones for the past couple of weeks (man do I have some serious respect for full time mom's) so I haven't got around to fixing it yet.

Never had any issues with the old dual 9L/9920 setup. Everything ran cool so I'm sure I could have played with the gearing a little bit more and got a few mph more out of it.
If you decide to run a dual setup, definitely try and run LiPo if you can because it will save you a couple of pounds (literally).
