About them not getting hot, I don't understand. Ineed more info. Are they charging good?


About the creek jump, we have rain scheduled for a few more days. :( As long as it stops before Sunday, that's my weekly gold day. ;)

Well you can have some of our sunshine! It's friggin' 93 degrees here today. As far as additional information, the charger I'm using is the SuperBrain 959. It has a plug-n-play mode, where you just hookup the battery, and hit start. It goes through a deep charge at 3.0 amps at 30mv peak threashold. Then it goes into a .1 amp trickle charge for 50 minutes.

I'm only getting 3-6 minutes of run time on the batteries before they die. I should be getting 15 minutes or so run time I would assume from a 1800, 6 cell flat battery on a 19 turn motor.

I remember back in the day that my batteries would get hot when they were charging, well, this is not the case. They stay nice and cool through the whole charging process. I'm trying a little different approach with the charger now, so I'll see if that works. I'm charging it at 1.0 amps, and at 05mv threshold to see if that makes a difference.

If not, I'm afraid that my charger might just be a lemon.
 
15 min?? Maybe with 3300's but you could at least expect twice what you are getting. I use the old black MRC (819?)charger, and my batteried get maybe 5* hotter than when they started. In other words, they stay cool. 50 min to charge?!?!?!?! It takes me 12-18 min with my 1700's. If you don't figure it out, I'll go look through my RC stuff and see if I can.

Well, as it is, the deep charge takes anywhere from 4-15 minutes (which seems real spiratic and inconsistant), it beeps, and according to the hobbie shop guy, that would be enough. If I leave the battery on the charger after the beep, then it goes into a trickle charge for another 50 min. At the end of the 50 minutes it goes into a sleep mode.

Like I said, I'm trying a new setting charging it at 1.0 amps, and 05mv, but I read somewhere to try 50mv to get peak charges. I just don't think I'm getting peak charges.....
 
Well, mine is alot simpler. After I plug mine up, 15 or so min later, the light flashes and it is done. I unplug it then I plug it back up to get a full peak. I leaned this trick while I was racing. Sorry that I can't help you right now, but Nate has a 959 and I'll go look at his tomorrow.



BTW, how do you like you truck? Did you look at the Stampede yet?

Oh man, Love the truck! IT'S AWESOME!!! I just wish I could have a little more play time inbetween battery packs. It seems to be a pretty well balanced truck for jumps, it flys nice an level. I might add it appears to be rather durable also, which is good for my learning curve. :) I'm really quite impressed at all the places this little 2WD car can go. I'm driving up 4-6" 90* curbs without a problem. Grass, gravel, lavarock, asphalt, dirt....I love it. Yesterday I was out racing cars driving down the street. They had some pretty wierd looks when this little RC car would drive past them (being ever so careful as to not drive under a tire or something ;)) Already, I'm seeing where a nitro car would certainly fill my palette. It's all grins, well built stadium truck!

I haven't touched the Stampede yet. My son's B-Day isn't until the 26th of this month, so I have about a week before we can drive together. This also sucks, because I have to hide my XXX-T from him until he gets his as well. So I guess, we both have something to look forward to. :)

You say you charge it, then plug in the battery a second time to get a peak charge? How many times do you plug it back into the charger?
 
Just once. After it goes 15 min or so, I plug it back up. Then when the light flashes(3-5min later)I run it, unless it is hot,then I let it cool.

Right on, I'll give that shot. I was alway afraid of damaging the batteries by putting them on the charger a second time before discharging them.

I'll let you know...

:-)
 
little tip about jumping.. you can adjust the pitch of the truck with throttle control while in the air. letting off the gas/hitting the brakes will pitch it forwards, more throttle will tend to cause it to jump more nose-up. usually the best landing is flat and level, to absorb the jar with all four shocks/tires etc., but of course it depends on the track condition you are landing on etc..
 
Ummm.......Yeah, that's pretty much common sense. Thanks anyway though. Creek pics will be next week for sure. I'm booked this weekend, parties n' stuff. :D

What will the difference in heavier/lighter weight oil in the shocks do for you? Also, different tension springs for the shocks?

Looking forward to those pics! :D

Even if you land in the water, post the shots... ;)
 
It wouldn't be the first time I've landed there. Rebuiling a siezed nitro engine sucks soooooo bad. I'm also gonna film it for my movie Dumba**. It's kinda like Jackass, but not as dangerous. It's mostly RC stuff, but other wierd stuff ,too. I need ideas BTW, we are running out. RC or not, all is welcome.

I have a T3 and I jump jump it all the time its only broke once and that was because it was ran over by a car,not jumping .I'll try to get pictures of my T3 and post them soon.
 
my first Nitro/real RC car.. Traxxas Nitro Hawk. Lost radio control to it and it jumped into a little stream, where it set for a good while because I couldn't get down to it to get it. When I finally got some help, and pulled her out, I didn't know what else to do than rip on the pullstart and cross my fingers! Lil bugger started up real rough, put off alotta smoke/steam and after a few minutes, ran like new. :D Those Image engines may not have been the most powerful, but you could put em through hell, tear em apart and put em back together 89 times, wrong, whatever, and they'd just start right back up. That's more than I can say for other brands, O.S. included. On the shocks questions, your best bet would be to get yourself a subscription to Car Action, if you don't already got one. They do tips for that type thing all the time, and you can learn quite alot from reading the rest of em etc. Basically, you don't want the tension of the springs too stiff, so it's not too bouncy, and you want the weight of the oil just right, so you don't bottom out too fast etc. A good rule of thumb is if you can drop your offroader from a good few feet or more and not bottom out the bottom of the vehical, you're in a good range. That's about all you really need to know until you get into racing and such. Oh, and again, get ya a sub to caraction, and read as much of em as you can. REALLY good learning source, and fun to read. :)
 
I would not suggest that you start racing just yet. I would wait until I truly know my car. Give yourself 3 or 4 months, then you should be ready.



Creek shots should be up by Wednesday, got to get some batteries for my car. Can't have it fly up the driveway at my mom's car again. ;)

Greets everyone,

I've been doing some research on getting into R/C cars or trucks. I mean, I aim to get my son one for his Birthday. I've only owned one R/C Truck that I built, and that was a looooong time ago. I no nothing on current specs or buying opinions of models... I have been reading some extordinary testimonials on HPI products, namely the Savage. A nitro-Monster Truck!

Any suggestions? Car or Truck, Gas or Electric?

:cheers:

I have a HPI Super Nitro Rally. Hpi is a prety good company. Nitro is very dirty. You'll have to clean it every time you run it to keep looking nice. I would get a T-Maxx over the savage though, 2 speed, forward and reverse. But its your choice. The savage is a decent car...Good luck!
 
He's already got one, but thanks anyway.



I almost bought a super nitro rally for my 3rd car, but decided not to. One of my 5 cars(RS4 Sport 2) was a good car, but that's another story.
