well just so happens that teh track only has one tight spot the rest of corners wer wide and long straits.

That is funny - I wish I lived close to some of the people who think electric can't keep up with nitro. I would love the chance to show people otherwise.

Most nitro's can't keep up with my electrics - All my car details are on my site: http://studysession.com The car pictured on the front of the site is one that I may be entering in the RC Car Action speed challenge with. I am testing with a few different cars.

On my site there is a video of Nitro TC3's that can't keep up with electric Micro RS4's. And another with 2 different people at a different place where a Nitro TC3 can not keep up with e XRAY M18. Both of those 1/18 scale pictured are electric. The MRS4 hasa a 540 conversion and the M18 is running the Mamba brushless. http://studysession.com/vids.html

The videos are not of my cars. I wish they were but they are from other people. I am hoping to have some video of my Micro RS4 against some nitros soon. But I do not right now.

Fire Rider - How did you measure your speed. I have done a lot of testing and the speed of your car? I am not trying to bust on you. Just I have a lot of experience at this. Unless you changed your internal ratio of the XXXS. Then i do not believe your speed claim at all. -- You could be right, but I still won't believe it until you either change to a motor with MUCH higher RPM's and More cells or change that gear ratio.

The internal ratio fo the XXXS is 1.83:1 so with pinion and spur you mentioned and peronal experience with the Novak. You need to check again.

For those who are reading and don't know. Gear ratios are determined by - Spur gear divided size by pinion size multiplied by tranny/internal ratio.

128 / 33 * 1.83 = 7.0981:1 gear ratio -

Sorry, but I have the Novak and with only 6 cells at that gear ration. It will not hit that speed.

I am sponsored by a few brushless motor and ESC manufactures and test the brushless products regularly. And I know with that being your gear ratio and using that motor. You need more cells to bring it above the 40 mark. With my RC's I do speed runs regularly with my cars. I just don't believe you are hitting any of those high speeds claimed.

For those interested - here are internal ratio's of most cars:
Associated TC3 2.5
Barracuda R2/R3 2.4375
Ho Bao Hyper 10 elec 2.13
HPI Pro3 2.25
HPI Pro 4 2.4375
Losi XXXS 1.83

Hey guys, my tc3 hits 60 mph off a 6 cell "Special" battery pack. Obviously it'll hit 180 mph if I put in 18 cells.

Just thought I'd start something up......

Dude, if you have problems with understanding motor springs then I really wonder how much help you can offer with anything at all.

I've helped him with more on his micro on other forums than you have since you've been on this forum.

Come on now - lets try to keep this one on subject.

I asked FIRE RIDER to tell us how he came up with those speeds. I personally tried that gear ratio with 6 cells on a touring car and it was high 30's but never hit 40. My car hit 38 - 39 each time. But never got passed the 39 until I went up to a taller gear ratio.

And with the Novak, I did not want to ruin it so I was not going to go past the 6 cells. Anyone that I know who went 7 cells with the Novaks had problems and sent it off for warranty repairs after. I figure I have other brushless systems to use, so I did not want to risk the Novak getting essed up.

Yes - on another forum AJG has helped me with a setup on my Micro RS4 = He has a 540 converted micro. I recently got one myself. Him and a few others been answering my questions on hop-ups and option for the 540 conversions. Want to see a cool video? On my website shows a 540 converted Micro RS4 racaing against a Nitro TC3. The NTC3 can not keep up:
http://studysession.com/vids.html

But this thread is about a TC3 and how fast it goes. And using the Venom Speed Meter to measure speed - I used an MTroniks Brushless ESC and a Lehner Brushless motor and was really conervative on the gearing. Went 56MPh using 12 cells. I can easily go up in gearing a go faster.

I am having the car redone to help with balance. 12 cells done up on a stock chassis of a TC3 does drive well going straight, but in turns it tends to lean to much. Once we are done with a new setup, I will be using same motor and the new MTroniks ESC I have now and will be using 12 cells and give it a go with taller gearing.

Once that is done, I will be using same setup using different brushless motors to compare how they perform.

Mine took ages to sell, nobody wanted to buy it, I can't say I blame them too much I lowered the price twice before it sold.

You might want to consider going to a stiffer suspension setup to help keep the car planted. What are you running for your shocks? I hope you're not hoping to make this car handle like it's on rails, since the handling will be compromised with 12 sub-c's on board. Are you running any sort of capped tire?

For now I am running some tires I get for free. Just some cheap rubber tires.

As it gets into the higher speeds, the tires balloon up to much. So I am going to need to change what I am using. Figure can do that later.

I am going to be meeting with a machine shop in Scarborough. They are going to help me with a new design for the car I have. Everything will be completely balanced when we are done and will be able to fit 24 cells with no problems after that. Right now, 12 is all that I can run with until them. Making more fit without modifying the car is to hard and keeping it balanced. So need to make a custom chassis and support bracket to allow everything to fit correctly. We are also doing this to give the car a lower center of gravity. It will be a few weeks before this process is finished. So until then I am just seeing what speeds I can reach with 12 cells.

On my Colt10 with 12 cells using the AXI motor and Schulze ESC I reached 93MPh. That is about the fastest I think I can go with only 12 cells. It will take a lot more power to push it much faster. This car I recently finished a custom chassis for testing. If it works, I will get the machine shop help me do a better one. Right now my work on the mill looks more like a hack job. I am enrolled in some machining classes for the winter semester at Harrogate College. This will help out a lot. But until then, I will get help from the machine shop in Scarborough.

Thx
