Hey guys, I received my Futaba MC230CR speed control today and need some help setting it up. By biggest problem is with the reverse. I followed the manual and set everything up and noticed that after going forward and returning to neutral the car keeps going forward slowly. Reverse works...

I just bought a pair of these Half 8's for my 5yr old son...I upgraded one to the X-speed motor, the 8 cell pack, the regulator and the oil filled shocks. He's having a ball with it, but has already blown one of the stock servos. Right now I have him up and running witht he servo out of the old...

Where do i find another usb cord to hook to my computer . That goes to my mamba max. Thanks for the help. Have the software not the other. Thanks.

hi to all got a problem with my mini inferno ARR version esc...the esc cannot go into reverse! only can go foward only...what can i do? get it repair (don't know who or where to send for repair cos i live in Singapore and most RC shops will say its my fault and no warranty covered) or get a new...

Yea, I'm keeping the stock gear. Why? I'm not a racer, but use them to 'perform' with my RC tanks. But I've got a ~bit~ of a problem. I got all my LAV's used, and only one of the trio came with a screw to mount the servo arm! Yep, that tiny M1.8x4 TP screw. Its NOT part of the replacement...

Hey guys, I'm relatively new to everything, but have a few buddies that have been helping me out. I picked up an MI and have had the ESC go bad so I've jumped into hopping it up. After lurking around several forums, I know I read somewhere (I thought it was here) that someone was using a Hitec...

This one is simple enough. Probably easier then a FET stack on an xmod. Here's what you need, but of course....some clippers, solder, copper braid, etc., will be helpful. First rip your old FET's off like a wild animal, like you hate your old FET's for they are stinky and weak.

So I recently put a brushless system into my MIST (Wraith and Quark), and used a Nanodragon Tx and a 27mhz AM Rx from Toyeast. Everything works normally and fine until the car gets about 15-20ft away from the Tx. Then the radio loses control of the car, and the car will continue moving on its own...

http://www.teamnovak.com/products/brushless/micro_brushless_motor/index.html Novak will soon release a 1/18th Sensor-based brushless motor and ESC combo!

Helo, I am from Brasil and new in RC cars. I have bad english write, SORRY. I have a mini inferno ST RTR 1/16 by Kyosho. Please, help me. I would like change the motor, better than, x-speed, by kyosho. I read a lot this forum and I have a lot of doubts. The doubts are: which does...

Does anybody know of a brushless/brushed ESC which is small enough to the MI ?

Hope someone can give me some advice : I bought a graphite chassis and flipped the motor around. Now I want to install everything but when I want to mount the servo and use the brace H (for the Hitec 81mg) I noticed its to close to the motor (see pictures) I'm hoping for some tips (with pics...

Hi, I was fed up with my H8's stock servo problem so today I bought a Hitec receiver, TGR micro servo (I think I'm the first here to use a TGR servo :) ) and a Novak Spy Esc. I'm running X-Speed motor with 8-cells but the novak esc is limited with 4-7 cells. For the first run with 8-cells it was...

I went to an R/C expo last weekend and picked up a few mini infernos. White body with friction shocks. Half an hour out of the box, I realized just how crumby the stock electronics are. So what did I do? Hoped on eBay and bought Hitec HS-81MG servos and Mamba Brushless 6800Kv...

If you're interested in finding the stall torque of a motor, you need: 1) A very good power supply capable of sustaining a set voltage while stalling the motor(hard to do with cells). 2) A method of measuring force(digital scale) 3) A lever of a known length 4) A motor First a note...

My sons stock h8's servo does not work. He still has full range of forward and reverse. Also is running on 9.6v. I disconnected it and pluged in my old stock servo, which does work, and it diddnt work either. Must be a problem with the esc/reciever. What happend and if I install my...

Hi, This guy on eBay assures me I can use an 11v 2 cell LiPo battery in my stock Half8 and it won't fry my ESC. I've ready elsewhere and advice from my LHS is that anything over 7.2v will kill the ESC. ...

Hey there, I'm tryin to decide whether or not to get the quark 22a or the 33a pro Is there Enough features to a 33a pro than a normal 33a to go for that? I am only using a hacker 13l motor anyway Thanks Adrian

Hey everyone, I can't afford to change the servo around just yet to work with the new receiver I have a am 27mhz receiver i'm using for the new brushless system, but I was wondering how i'd go about actually getting the stock servo to work in a 3 wire setup? Thanks

Has any body attatched a fan to their Quark esc? How could I attatch one to the heatsink?
