Just wonder how you get the lap times that's all!

I love it when you guys are doubting me, that's why this hobby never gets boring.:lol:

I have a lap system on my JR xs3 pro radio, I ain't going to spend $200 on a radio and not have a lap system.

Shall we have a 20 page thread how inaccurate my lap counter is on my JR radio?:lol:

My average time is in the low 20's, I only managed to pull off one lap of 18.2

No, we only need 1 to tell you that your thumb is fast. The only way to get an accurate time is with the timing system or when someone else is holding a stopwatch. It's very difficult to use the lap feature on the radio WHILE you're driving and get an accurate time. When I tried it, I was 1-2 seconds off what I usually run. Thats a big big difference. Now I know what you're gonna say, that you are pressing the button on time and blah blah blah, but it doesn't matter cause NO ONE here is gonna make you understand that. You tend to be pretty stubborn when someone has something to say. When fast guys are giving you advice, don't question it. Take it. I notice that you seem to want to argue and debate the advice! Thats probably one of the reasons why certain people at the track like to keep their distance.

No offense what so ever nor have any doubt on your radio! I just can not believe if your car is not handling right and you werent shifting right, with not proper gearing, with not proper tire size, probably not the best set up! with all these variables, it is next to impossible to do 18's laps over at crystal park!

I might be dumb or not good at this hobby, but it took me a long while to break 18's lap and now I am in low to mid 16's

One more thing, if you had to ask someone for advise that means you dont know the answer to your question! So Please take it not arguring on the advise. If you keep on doing that no one will ever give you and advise or help!

Just my $0.02

I have noticed there are certain people that ask a question, and if they don't like the answer they want to then argue about it.

my radio has a lap counter on it too but never used it. i found it hard to concentrate on my driving while try to keep the lap time at the same time. maybe you can do better than most of us, young kid's reflexes is hard to beat.

wish they put a mp3 player on it instead.

LoL, may be young kids can handle a VCR or DVD on their radio too! better yet, they might be able to handle driving the car on the radio with camera on the car itself?

you are right, every time I have to press the lap button I have to let go off the trigger a little bit. I usually press the lap button at the same place on the track. Never early, usually late.

Actually the first day i brought the radio I started out with 25 second laps and the time kept going down. It just keeps getting better with practice.:D

I'll try to make it next weekend, I've been really busy.

not necessarily. It may appear on paper that you loose 3mph at top end with lower gearing but you also have to factor in another factor which cant be figured. When you drop the gearing it also allows the engine to rev harder which adds more mph than gearing up.

This is the reason many people dont get the best out of their engines. They dont make the end of the straight with a certain gearing so they believe they have to gear up. The simple fact is the engine is not capable of pulling the original gearing and needs to drop a tooth to pull the car.

So if you didnt try to time your laps using your lap counter on your radio, you probably would've clocked a 17.2 instead of the 18.2. Not bad, Not bad at all. Consistent 17's would make you a B-Main winner at CPR.:D

compaq888 09-06-2004 09:07 PM

I got a long way before I can even think about racing. I drive differently when there is other cars on the track, I tend to crash more because I have to get off the "line" so they can either pass or I start driving fast.

Right now my main concern is to get everything out of the motor, the car, and myself.

This is natural and nothing to worry about. We all have went through this. The only way to get through this stage is to keep practising with other cars on the track and try your best to ignore the fact they are there.

A little secret to help you on your way. The hardest thing to master is sticking to your line when faster guys are lapping you. Hook up with some of the faster guys and ask them to help work on this. Get them to talk to you when they are coming up behind. A good racer will always say in a friendly manner he is lapping you.

Sticking to your line is always better on straights cause when you start darting all over the track and jumping on the breaks you end up collecting the faster guy and breaking more parts.

If he is that much faster he will be fast enough to get past you safely without you slowing down or driving off your line.

In corners before easing off the throttle to let him past say which way you are going to go so he can pass safely. No need to drive off the track to let him past. Just run a couple of car widths off the racing line.

Hope this helps

x12 non turbo rody version vs v12 non turbo rody version
 
Someone told me that the v12 non turbo rody version is exactly the same engine as the x12 non turbo rody version. Is it true?

compaq888 09-08-2004 01:21 PM

what I have been told was that the RB v12 non turbo makes the same power as the X12 turbo.

Solara 09-08-2004 02:16 PM

For $170 V12..............I don't see why V12 is NOT one of the best bargain and fast engine to have....too bad nitro season is almost the end...otherwise, that will be in my R40 for sure.

410 is non turbo but with a slightly modified crank. 430 is turbo but a stock crank. non turbo runs cooler.

:confused: :confused: :confused: How is that possible?

Scott Fisher 09-09-2004 12:01 PM

The crankshaft and the case is different on the x12 versus the v12. The V12 uses larger bearings to support the larger crank. Because the bearings are larger they had to make the holes in the case larger. Not only that, but the V12 case is supposed to have some fins on it to make it stiffer. I have both engines, but haven't actually put them side by side.

We are talking about V12 engines 410 and 430, because there was a 410 and 430 on the old X12 series.
So in the new V12 series the difference is that 410 is Std head (for normal plugs) and a crank without turbo scoop. The 430 has a turbo head (for turbo plugs) and a crank with turbo scoop. Other than that, the rest is exactly the same...crank timing, sleeve porting and timing, etc. etc.
The difference between old X12 series and new V12 series is that the old series had the 11mm crank and no milling of the base of boost port on the crankcase. The new series has 11.5mm crank and milling on the base of boost port of crankcase, and new series gets different crank bearings, front is smaller in external dia. and rear is bigger in internal dia. so crankcase is different size too.

How hot were you running and what kind of plug and what gearing?? and tire side? (front to back) are you running overdrive and such?

I was trying to run only on the 1st gear as he does, but failed. All the cars passed me. I was just wondering why my engine is not that powerful as his. :(

come to think of it, 5 supposed to be faster than 3 on the straight, but it isn't!:cry:

Depends on too many factors. Head clearance, nitro %, pipe and pipe length, timing, length of the straight etc.

With the correct set up a 3-port will match any 5-port for power. Technically, any engine only has 3 main ports and an exhaust port. What the manufacturers refer to as a 5/7/8 port etc engine is just taking the 3 main ports and splitting them up to direct the flow of the mixture as they want it to maximise the efficiency of the engine. This does increase the performance of the engine but only if the straight is substantially long.

Those are the old series X12 RB engines, that's why you won't find info on their web site. They've been replaced by the new V12 series. They were equivalent to the old RS12 series of Novarossi engines. What I can't remember specifically is what the 340 engine was. I had a 310 RB and it was a 5 port turbo engine, and I think the 340 was a Rody tuned engine, but i don't know if it was 3 or 5 port turbo or non turbo.
If somebody is offering you one, ask him if it is 3 or 5 port and if it has a black crankcase, if does than it is a Rody tuned version, great engine.........very fast.
