ASF AWD vs. MR03 board

Greetings...

I got an asf awd board (with out wires, switch, servo motor, and pot)... and was wondering if the awd board is exactly the same as the mr03 board? I remember seeing a small sticker with "Type C" on some boards... just can't remember if it was on a mr03 or awd board...

Another question I have is, are they wired the same - particularly the servo motor and potentiometer, or is the polarity switched?

Hope to swap out an AM mr015 and solder the switch, servo motor and pot onto the asf awd board with the proper wire orientation and would appreciate any tips and info on the awd and mr03 asf boards...

I remember arch documenting different boards complete with part numbers... however couldn't find the particular thread...

Thanks in advance for any reply...

I have the same situation. I have an ASF Awd board and want to see if it will work in an MR03. I already have the appropriate smaller MR03 servo motor, but need to know how to rewire the potentiometer. Also, I just want to verify an ASF Awd board will be able to properly operate the servo, since the gearing is different. Thank for any input and directions.

ASF AWD boards should be of the MR02 variant, not the MR03 if memory serves correct. There is only one port on the top side of the board, although I think the polarity of the servo is opposite for the AWD, but dont remember exactly.

I swapped in a VE board into my AWD recently, and think that I needed to reverse the servo motor.

Many thanks again for the input and sharing the info EMU... you're like a walking mini-z encyclopedia... Hopefully when I do get the time and do it, I will post my results here...

Hmm now that you mentioned it, the asf awd board uses the bigger servo motor right? Compared to the smaller mr03 servo motor... in that sense I guess it is like more of the mr02 asf variant...

I'm also a bit curious as to how would you rate the different boards that kyosho came out with...
I know that kyosho just recently came out with a board that has the option of using different radio systems via using plug in receiver...

But I'm more interested in boards just prior to this more particularly the mr03 line... minus the sport / sport2 series (lol)...

I think ratings would be based on the fets that they used or maybe other electrical components being used...

Would love to hear anybody's thoughts... and thanks again in advance...

In general, the AWD board is equal to the MR02 board. Same layout and electronic package, just has a different wiring for the servo.

I have had debates with a buddy of mine about the different electronic packages. He feels strongly that the AD board is better than the AD board for the MR02 despite not being ASF. He feels that they used higher quality electronics on the board despite having the same fets. I am no electronics engineer, so I really cannot comment on the other components. I do know that the AD board had suffered from static issues, but when it worked, it worked quite well and had a different feel than the ASF boards of its time, with slightly more resolution on the ESC and a stronger feel on the steering. I attribute this to the programming on the ICS more than the components used on the board, but he is convinced.

As for the electronics, I feel that all ASF boards prior to the MR03 (MR02/015/AWD/F1) were all the same, just with different servo arrangements. With the release of the MR03, the electronics package was improved, although retained the same ESC design. The steering was the most noticeable improvement, there seemed to be a higher resolution, and the reverse delay was greatly reduced. The biggest issue that I had with this electronics package was that virtual inertia was enabled by default.

The MR03 Tiki-tiki board was another refinement, and is arguably the best ASF board produced, even with the chase mode disabled. This seems to glitch less than the earlier MR03 ASF boards. The difference was very little in performance of the ESC package, but the Tiki-tiki board had a slightly more aggressive initial ICS programming from what I remember.

That is about all of the ASF boards for Mini-Z, if I would look for a board, I would look for the Tiki-tiki board first. The MR02 style boards, should all expect to need to have virtual inertia disabled, unless that is your thing. I never liked virtual inertia, and felt that it made the car inconsistent entering the corner depending on how you let off the throttle. If you came off completely, quickly, I felt the car would roll much more than I want. But, if you came off slowly just barely riding the throttle before releasing, the car would have much more drag brake. Disabling the "feature" was a necessity for me, it felt more like a handicap when enabled than an assist.

Many thanks for your in depth review... highly appreciated...

I do remember waaay back, during a visit to a HK track... that almost everybody was using the AD band board in their cars... I was thinking to myself, like what gives? So I guess it must've been a solid platform to serious racers...

Compared to AM, AD was so much better. Compared to MR02 ASF, I felt that it was more or less equal. Where my friend feels that it is better is the throttle feel and steering resolution. He feels that it was notably higher than the MR02 ASF, however, I didnt notice much difference in that regard. He now has my AD cars, and still uses them. I am slowly migrating my gear to brushless, it is just so much less maintenance and more consistent.

Based on some of my experiences, you can swap an MR03 board into an 02-AWD-F1 but swapping an 02-AWD-F1 board into an MR03 has always failed for me.

The servo motor is the biggest issue as every time I've swapped on a 03 servo motor onto an ASF 02-AWD-F1 board I get a really strange servo "bounce" effect in the steering....it reacts very strangely almost over jittery and doesn't so much center as it speed wobbles back and forth to center eventually.

I never examined if there was an ICS setting to adjust I just gave up on the swap.

Thanks for the info... maybe components to drive the 03 servo motors vs bigger 02 servo motors are different? Maybe somebody can chime in...

This could be related to ICS settings? Possibly punch needs to be lowered?
