Psycho; not sure yet...

I think why they put 4WD on a F1 cas is to make it easier to drive...

haha, i will take off the shaft too and make it 2WD...less weight too..

if it was engineered for 4WD it might not work as good if you convert to 2WD......I would love to ask the Tamiya designers WHYYYYY!

I was really excited about the new f car..... now... I am fully let down, sure it has some new features, but it is just another touring car. F1 is great casue it is simple, and fast. making a 4wd F1.. just does not seem right, and no scale... Ohh well.

I was talking to a couple guys about this last night. We were thinking that we should be able to make our own chassis that will accept a Cross frontend and the Tamiya rearend. I guess we just have to wait and see what the new car really looks like. I'm with spooky, though... what a let down. The only thing I can think of is that a) they are bowing to the pressure of the touring car market b) they want to build it cheap and use TB01 parts. Oh well, I'll still buy one.

The Cross accepts the tamiya rear end....in fact they sell a complete conversion to a t-bar rear for that car....so your work is done :-)

Hi guys, I see many ppl using small esc for their F1 chassis...
I got a Quantum Sport ESC, the lowest spec one. Right now
I'm running it in my HPI micro. Works great.
I was just wondering if i use this ESC on my F1, Would i fry this ESC, this esc spec is like;
Rate Current - 80Amp...[how much amp draws for a 540 sport tune motor?] is this enough?
Max. Current(30sec.) - 40A What is this?
Cont. Current(5min.) - 30A And this?
and those B.E.C stuff
Output Voltage - 5.0V
Current(30sec.) - 2.0V
Current(5min.) - 1.2V [what are this?]
Can you guess explain this to me, I want to learn all this stuff and get better understanding of the ESC.
So should i use this ESC on 1/10 F1 or just invest a GM V12WE??

I use the same ESC in F1 and sedan. I've run stock and as low as 19 turn modified with it and have seen no ill effects. I think it's rated to handle as low as a 14 turn motor, if I remember correctly. It should say in the instruction. All the current ratings and times you are referring to are the amount of current that is being drawn through the esc and the duration that it can handle this amount of current. To use the analogy of drinking a soda with a straw, the sucking force that pulls the soda into your mouth is like the force the motor has pulling the electrons through the esc, wire, etc. This force is rated in amps. You would have to throw your motor on a dyno to get this type of data for it. Don't try measuring it with ordinary electronic test equipment! You'll fry it and risk electricution. It only takes 500ma (1/2 of an amp) to kill a human and you lose muscle control at 250ma (1/4 of an amp.)

If you sold your F1 car, get a Cross Fireforce. They are about the same price as an F103RS and a lot cooler (imo.) I love the tuning features of the car.

Isn't the graphite axle better than fiberglass?
I had the Ti axle.... don't get it... it only lasted 1 race. Bends easy.

I use the graphite axles and they work great. They are getting increasingly scarce, though. It's good to know that we have another option.

I finally got to put some laps into that decked out F103RS I bought used last year. It was a blast! I had more fun driving that car, than I have had driving TC's in a long while.

Had a serious push going through the corners. I didn't have to worry about spinning out at all though. Got any tips to get a little more steering?

I have the:

ball link rear suspension
Link type front suspension(also have the solid front)
Tamiya type B tires

Any advice?
