Those are great runs Al.
Shutdown and adequate power are big problems when you start to go faster.
I realized that quickly when I noticed speeds dropping off a lot when I put
only a single 10 amp supply to an individual lane. Speeds dropped off 10 mph over
the parallel 20 amp hookup.
On my track I think 60 mph will be the max I can handle with my stopping setup.
Even on my setup it was hard to watch a race. Running near a 1/4 second
and near 60 mph all you see is a blur.
I imagine at the higher speeds you cannot see anything. Slow motion cameras would be
the only way to watch a race.
It is even more amazing when you realize those cars would beat Top Fuel Dragsters
badly for the first 20' and most likely would be ahead at the 60' mark too.
T/F and F/C only manage something in the .8s in 60'.

I would like to see one of these cars run a dragster it would be so funny to see a half million dollar car get beat by a $100 slot car

We got a couple of the new afx cars. I'm real surprised with them rolling the axle with fingers is butter smooth. I figured they would be slow since there is absolutely no resistance at axle but they fly to be stock. Need better traction magnets though. Do they make any performance parts for these yet.

I have some of the new inline AFX G + cars. They run pretty good but can't come near the BSRT G3 cars.

That's what I have they move pretty good for a cheap car. I'm surprised cause you cant even tell your turning the motor when you roll tires. I have some tycos that's faster but for box stock there pretty fun and run real cool. We pulled a 50 lap race a few mins ago and the afx was cool to the touch and the Tyco well ot left a blister on my finger lol thinking about putting a Parma 1/32nd motor on one and see what it does.

I lied Dave its the mega f cars. I think. There the cars with the can motor and circuit board. They need stronger traction magnets though.

Tomy , Mega G.......... new chassis has circut board. Old was 1.5 & 1.7 , different chassis lengths. Pretty amazing how quiet & smooth. And what the tiny can mtr will do.
Be intresting to see a comparison between this and other stock chassis. Consider what things are....... one motor mag from G3 is close to size of whole can mtr in new Mega G.

Don't think performance parts are made for this chassis. As with AW's Super III , I think replacement parts are available for now for older Mega G's. Only have one of these new chassis........ adding shunt or jumper wires to bypass circut will turn that little can loose. Did so when getting chassis....... .. with shunts car became torque monster on take-off. Not sure about top end have not been able to check. Curious how consistent times might be with mechanical operation being so smooth. .......... Peter |

Peter I can tell you that after 50 laps on a 9ftx4ft track that little guy was still running about the same and motor was cool to the touch. There pretty fast on the top end I ran it with a stock Tyco 440 3.5 ohm the Tyco started to slow and got hot enough that it blistered my finger when I grabbed it out of the track. They need a little better traction mag and I need to figure out some kind of clip to hold the motor in better when it jumps track weather it hits anything or not the motor pops loose on the crown gear end. I think I'm going to use a small piece of wire and make a clip.

Dave i meant mega g I hit the wrong button. Lol big fingers little phone. I think its is just quietens the motor from noise I don't see any other purpose. I will send you a pic of the car I'm talking about when I get back to the house.

the circuit board supposedly eliminates emmisions which can play games with cell phones and such

The PCBS in the new car is for EMI suppression. This has been around for years over in Europe. The circuit on the board is a small filter network to help reduce electrical motor noise being generated at the brushes of aa DC motor. Get yourself an old AM radio and tune it off a station and you will hear the noise as you rev up the motor.
Seems our FCC has decided to look into it after all these years and would not be surprised to see it on more and more toys etc. To my understanding if it bothers you neighbors radio or TV you have to work it out .
Biggest thing for us is it drops about 1 to 2 volts to the motor meaning less RPM depending on the type curcuit used.
I have one of the can motors torn down and will take some readings on the arm when I get back home. I am in Atlanta GA At the moment and heading to New York then back to Dallas Tuesday
