    Mk2 escort

    I've seen a video on youtube where RC Kicks fitted the Tamiya Ford Escort Bodyshell to a Tamiya M-08 chassis. I wondered if anyone else is trying this set up and if so, does the M-08 chassis allow for different ride height settings on the suspension?

    MF-01X Servo Suitability?

    in Build Tips and Techniques

    Posted

    Hello,

    I have the new Tamiya Ford Escort MK II which of course comes with the MF-01X chassis. As part of the purchase bundle, I have an inexpensive Tamiya-Carsen Low Profile Steering Servo CS3 with metal gears.

    However, I have also got hold of the Yeah Racing Suspension upgrade suspension kit for this chassis, and it's recommended to use a higher torque steering servo.

    So my questions are:

    1. Is the Carsen-Tamiya CS3 up to the job?

    2. If not, then which  steering servo should I use that will fit into the limited space for the MX-01X?

    3. Does anyone have any experience of steering servo torque issues on the Tamiya MF-01X, particularly with an ugraded suspension?

    Many thanks and kind regards. kitefighter

    How does electronic braking work?

    Hello everyone.

    As I was having fun running my Tamiya M-07 in the large open plan office after working hours (as you do), I tried practicing driving faster and faster and then triggering the brakes. It was great fun on the carpet and even more on the shiny floor with the car skidding to a halt.

    The only thing is, I haven't really much idea of what electronic braking is and how it works. Anyone care to explain?

    Is this how it works?

    Thanks.

    Is the problem just affecting the ESC, or is the steering servo twitching as well?

    If you swap the ESC and servo leads at the receiver, does the ESC continue to misbehave or does the ESC settle down and the servo start twitching?

    When you say you cleaned the car - did you use water, and could any have got into the receiver?  Did you unplug the servo leads when you cleaned it and if so have they gone back in the right sockets and the right way around?

    Is the receiver antenna cut, split or touching anything metal, or close to the battery or motor leads?  Are any other leads cut, kinked or snagged?

    Is the transmitter battery fully charged?

    You could try re-binding the transmitter to the receiver, and going through the ESC calibration steps again.

    Thanks for your help here. I didn't notice the steering servo twitching.

    Haven't tried swapping the ESC and servo leads but will try and see what happens.

    I used a dry cloth to clean carpet dust on the body. Didn't touch the electrics. I did un plug the battery leads to re-route but will check I didn't reconnect back to front. (I'm sure I didn't because I checked beforehand).

    *Antenna lead! I have attached the battery leads to the same post as the antenna so maybe this is the problem! I will change back and see what happens.*

    Transmitter has recently new batteries but will change.

    If all else fails, will rebind.

    I think it has to be the antenna lead and battery lead being in close proximity because that's the one thing I changed yesterday. Thanks again for your help good sir. (or madam).

    What ESC is it? I have had to recalibrate an ESC before, just started doing random things by itself. This was in offroad cars and I put it down to knocks from the jumps.

    Otherwise no idea

    Hello,

    The ESC is a Hobbywing Quicrun 1060 Brushed Waterproof.

    Did you calibrate the ESC and the radio gear? I've never had a problem with a TBLE-02S doing that but every other ESC I've used needed calibrating.

    I didn't need to calibrate as I installed it last year without any problems. Everything has been fine, including from the weekend test run on a carpet. All I did today was to clean up the model ready for it's next trial, and it was whilst testing the model on the table that something has gone wrong. It must be the controller because if I turn the model on and not the controller, everything is normal. But when I now turn it on, it's as if the Speed Controller is getting a signal to perform some rapid test. The car will crash if I don't fix this.

    Hello

    I am using Absima CR3P controller and receiver. All of a sudden, the controller is sending a signal to the receiver to go forward, then max speed, then backwards. I'm not touching the trigger and its not a trim problem. 

    Any ideas how to fix? Never had this problem before and the system is still under warranty.

    Tamiya M-07 Chassis: Hard or Soft Anti-Roll Bars?

    in General discussions

    Posted

    Hello,

    Thanks for the reply and explanation. I also looked up some further interesting advice (please see below). I'm familiar with the understeer characteristics of a real front wheel drive car, particularly when lifting off power during cornering. Not something to worry about unless driving hard or cornering at speed in a real car. However, the Tamiya M-07 is clearly a designed as racing car and mine will be driven at speed on a carpet.

    As as trial, I have fitted the soft anti-roll bar to the front and the hard to the back. Although I question in reality how similar in full size front wheel drive car (or any other drive) is compared to a 1/10 scale model of the same configuration. The physics of a RC car in miniature on a carpet at unscale speeds must have many differences from the dynamics of a different construction real car on road.

    I must also add that the M-07 chassis is a great pleasure to work on as with all Tamiya models I've encountered, everything just seems to fit together like a well made watch whose movement you never see when the case (or in this case body) is fastened back on. (Please see picture at the bottom).

    So, What Have You Done Today?

    Went to Japanese Performance Show last weekend at Stoneleigh, which offered visitors the opportunity to run their RC cars on the specially prepared short circuit. So I took a Tamiya M-07 with a Datsun 510 body I recently built but haven't driven properly for a test run. It looked a bit odd mixing with experienced drift cars and my 9 year old son who was driving was told to slow down. Does anyone know of an indoor circuit with a long straight in the East of England?

    I'm afraid such wonderful hobby as RC racing is wasted on me. I simply haven't the skills or courage to drive an RC car as aggressively as a proper racer or tuner. The fun was in building the model and looking at the result. Hats off to those who build their RC cars to drive them as they were designed. Here is someone who knows how. (with credit to the originator of the clip).

    Thanks. Unfortunately, the body is too fragile for serious use and I've found the model too fast for my skill levels. I recently went to a local RC club where they raced Tamiya Mini RC chassis cars and the speed and ferocity of the collisions made me wimp out. So I think this is a great model, but I'm not a racer and this model will end up being a "Shelf Queen".
