RC Driving Style
I'm an RC newbie with no experience out side of the walmart-tyco special. ;) This weekend I took my new Maximum ST out to do a little break in. The events of the day I'm sure will leave you seasoned RC addicts rolling on the floor laughing.

To start the comedy of errors, I realized Saturday morning that I should have plugged my glow igniter in the night before. I read the box and sure enough 12-14 hours needed the first charge. I plugged it in anyway and let it charge for 6 hours.

Not knowing if the thing would start in 32 degree weather with a glow igniter that had only charged for 6 hours, I figured I put only a little bit of gas in the tank and try to start it out on my porch. I followed the book and gave it hell. Nothing. Glow igniter needs juice I thought. I removed the glow plug and hooked it up to the igniter. It was plenty hot. I replaced the glow plug and tried again, manually giving it some gas. It fired right up. I filled the tank the rest of the way and packed it out to the street.
Problem #1 solved – engine started. Problem #2: when I would let go of the throttle it would die. During break in, I had to use the trim on my throttle to make it idle. To make matters worse, if I had to use the breaks, it would die instantly. I knew it had to be the carb. I checked the books again. The high-speed needle wasn't the problem so I tinkered with the low speed needle. Didn't help. So I put it back. I read the book again. The third adjustment didn't get much justice. The "throttle stop screw" (or idle stop) just didn't make any sense. The Duratrax instructions tell next to nothing about it. I later developed the theory that this is a physical stop on the throttle mechanism. When you let loose of the throttle, the throttle stop screw decides where throttle rests. I gave it a turn or two and TADA! That was it.
Problem #2 solved—truck didn't die any more. Problem #3: the whole time I was running the truck around, the controller was inverted. I had to turn the wheel left to go right and I had to push the trigger to give it gas instead of pull it, etc. It was annoying. After the first tank of gas into the break in, I figured I'd call it a day and see what I did wrong when I hooked the servo's up. I know I oriented them right. I figured it must electrical (seems so stupid now). Later that night, I took the receiver off and flipped it over. You can't plug the servos in wrong; all of the wire plugs are notched. That wasn’t the problem. I then looked at the controller....... Hummm... what’s this? .... a door?!?! …. with switches inside ?!?!? Will you look at that "servo reverse". I guess the choice to not read the futaba book had come back to bite me.

All in all, it was good. I learned a lot and didn't damage anything with my stupid mistakes. I can't wait to finish breaking it in (with the controls not in reverse) :D

Sounds like a good day all around.
You learned many things. I think you'll do well in the days to follow.

Don't try adjusting your engine any more until you run a tank or two of fuel through it. Then, only turn the High speed needle clockwise 1/16th of a turn per tank until you start to get some power. Don't try running it hard or going past 1/2 throttle until after the 3-4 tank. Brake in will make or brake an engine.

Do a search on this forum to find many answers to your questions.

Glad to have you here.
 
Dude that is Awsome you had a good first day in my opion. Hell you got it started and got it to idle a bit. The idle screw is for setting the idle you turn it clockwise to open it and it will let in more air which will cause the truck to idle higher. turn it counter clockwise and it closes it which makes less air which means lower idle..

Man again good job. You figured out some very key things on your own. I have a felling this hobby will come pretty naturally to you. In a month you will be reading some of the stuff that other newbies do and you will think your first day was a walk in the park.

Also did you get any blisters from pulling on the starter? That means you poped your R/C cherry...X
 
That was a great day indeed. My first shot was pretty painful. A blister on both fingers for my pull start, and even a wierd experience with glow plugs. I melted two in a row! heheh

But that day is alot better than the day my friend had with his Tmaxx. Couldnt start it, flooded it about 40 times, ran the EZ start battery dead twice. When he FINALLY got it started, he fouled a glow plug 1/4 through the first tank. HE was so pissed. When the time came for the body, he overheated 4 times. Come along the mixture adjustment time, he had no more problems with plugs or overheating. But that was 4 plugs and 6 charges for the EZ start later. :P

Good luck with it, I'm still a "newbyish" myself. But I'm already on my second engine, it's coming to be VERY eventful.
 
My first day out was kinda crappy i got my xxxnt started fine and was just putzin around when my friends rusty came flying twards me and hit the losi dead on, broke front arm and shock tower...... so much for breaking in the engine that night
 
Dang. My first day was easy. LOL

Thanks for the welcome guys. :) There isn’t anyone around here I can learn this stuff from. You guys will just have to put up with my questions. :P

Ahhh. Makes since -- I had to turn it clockwise to raise the idle and make it work. Must have just come set too low from the factory or it's an altitude thing (5,000 ft or so here).

LOL Nope. As soon as I gave it some throttle, it fired up every time. I only had to yank the cord 20-30 times before I tried giving it some gas. Not enough for blisters. :D

The ground is dry and the weather is looking a bit sunny. I think may run another tank of gas through after work. I think I'm getting the R/C bug. :ahh:

I just got my truck about three weeks ago and I'm hooked I'm already wanting another car, springs coming the bug is going to get all of us
 
I got that bug in dead winter. I plow the roads for a living, and I made SURE that my road was WIDE. Accidently tore up about 2 feet of my yard. :D lol Those windrows (Snow piles on side of road) make some sweet jumps. :)
 
Yeah the snow sucks. We got almost 20 inches the other week. It was snowing for my first run. LOL didn't hurt anything but it was covered in snow. I just got lucky I think.
 
Same here, that lil RC10 didn't like that powerdery stuff at all, but with the top hard, it ran good, unless it buried itself. :D One server and a reciever down the tuber, thank god for RPM's reciever box. :D
 
LOL. I was thinking about that snow proofing thing, but I think I'll just stay on the road and out of the snow until the weather lets up.
 
I ran my xxxnt in the snow and fried my on off switch so i had to eliminate it now i just plug in my batt. when i want to run it. That also eliminates the accidental turn off by a marshall
 
Maybe I should snow proof my truck. You guys have already had problems LOL. It sounds like all you have to do is open your servo and reciever and get some silicone in there where the pieces come together. Then you have to put the batteries in a baloon or something. At least this is march and the seaon is about over.
 
Welcome to our world. Sounds like you had a blast. Good on you for getting out in the cold and making things work.

Just make sure that you are not allowing the engine to cool down out in the snow (bad things happen to the internals of the engine when they cool from 200+ to below freezing in a rapid fashion).
 
I'll keep that in mind. I haven't let it sit out in the cold yet after a run. After I'm done I drag it back in the house.

Wonder if my sig works.... :)
 
yeah your sig works. I've found one thing that works is when your donr driving it when its cold you can put it on the floor of your car and the heater will let it cool gradually
 
I'll remember that one. Today I'm not going to leave my street. Just going to run it slow and break it in. Can't wait to open it up :D
 
I'm a newbie as well, all I can say is stay tooned to this Board, you find a lot of your answers before you learn the hard way.

Last night I ran another two tanks through only a couple more tanks left for break in. I can't wait to get out there tonight. I wish I didn't have to work until 5. I'm so hooked. :D

When you're breaking an engine in, you're supposed to gradually lean the engine to normal carb settings as you get close to tanks 4 and 5, right?

Yeah that is correct around 5 or 6 you should be getting to the optimal settings. Them normally around 10 tanks you can start leaning it out for a little more power. X
