Does anyone know what size the tq70 front and tq20 rears are?

like 2.2 x 1.5? 2.1 x 1? any ideas? im not great with tire sizing


Also does anyone have a list of what size turnbuckles a black pan/long arm rc10 takes off the top of their heads? for 3 suspensions mounts, servo/servo saver?


Also did they ever make a 5-40 nut size aluminum/other wheel axle for the front for a rc10? i found some alloy knockoffs in 5-40 and 8/32 supposedly for the rc10, i always though it was 4-40 there.

ok someone just told me 4-40 and 5-40 are nearly identical and will fit each other. is that true?

Not true.

The front axles were 4-40 and not 5-40. The diff nut on the 6-gear was 5-40. They are similar thread sizes, but not the same.

The numbers on screw sizes are simple to remember.

The first number is the general shaft/shank size of the screw without threads, relating to the diameter. A 2-56 is a #2 size screw that will use a #2 washer. A 10-32 is a #10 sized screw and uses a #10 washer.

The second number is the number of threads per inch. A 4-40 has 40 threads per inch, as does a 5-40. A 2-56 has 56 TPI. The difference is, the shank size is different from the 4-40 to the 5-40. While a 5-40 nut will spin down on a 4-40 threaded screw, the I.D. of the 5-40 is larger, and will probably strip pretty easily if torqued even a hair too much. They will also loosen up almost instantly if you use the car, because they are not mated sizes or surfaces. You'll never get them tightened properly at all. If you want to see a textbook example of that, check out this video. It's funny, but not funny, and it's what happens when you have similar threads per inch and not the correct stud size.

For a shelf queen, no biggie. But if you want to use anything in battle, DON'T mix and match thread sizes like that.

they will, but your front end will be wider. also, you need to make sure you have the correct steering knuckles for them, too.

tq20's are 2.1, and the tq70's are 2.0.

tie rods:

steering - 2.06
front camber - 1.65
rear camber - 1.25
centerlink - 1.00

awesome, what the the width btw, i know i could probably take a ruler out and measure but i wanna be sure, im a little dense like i said when it came to rims/tires etc

[scr8p]

i'm not sure about that. the fronts are probably 3/4", and the rears could be 1 1/4", maybe 1 1/2".
