So where's the link to that? I keep hearing about this conversion but can't seem to find it on the web. I'm just curious to see how they did it and how it works with AWD cars.

Thanks in advance!

Can't see the diference in converting a regular ASF board from 02 to AWD and 03 to AWD.
Just use the stock AWD servo motor ;)

I just try convert to MR02, seem really good, you need switch the servo motor wire Black/Red, and also servo wire Green/Orange.

Since servo assy as a whole in AWD is already a step above that of 02 as is one in 03, is there a point?

The reason I'd like an MR03 PCB installed on my AWD's is for the elimination of the reverse delay.:D Even though I can get into reverse 8 or 9 times out of 10 on my RA-18 2.4ghz-ASF PCB AWD's and MR02's, that 1 or 2 times that I "miss" getting into reverse can really cost me.:(

OK, so you need to use the original AWD servo motor, not the core-less 03 servo motor; What about the servo gear ratio changes that the 03 has compared to the MR02? Does this come into play at all, or is does this not affect the AWD's servo performance (negatively or positively)?

@PNRacing - Thanks for the info Philip:D

@TJ - Do you think you'll post a tutorial maybe on converting the MA010 and/or MR02 chassis over to the 03's RA-22 PCB unit? This sounds like something right up your alley buddy:D:D

I had a wedding... I think that's a pretty good excuse. ;) I heard Atomic will have theirs in Thailand and from what I was told, those guys in the other side of the globe are FAST!!! I want to experience racing with them so I need to see where PN will have theirs next year, so that I can pick wisely. :) :D

Cool Matt! I'm barely gathering the ground straps I need to attach to myself before touching this board. LOL I'm also trying to piece together another awd for this project. I don't want to touch my reflex'd out awd. ;)

Keep us posted.

hey guys you cannot use the 03 board on the 02 or AWD because of the servo, the 03 uses a digital servo and when you swap boards the steering is choppy and pretty much undriveable. Robert at atomic mods tried to swap an 02 board into my 03, i can only assume that you will have the some problem, but maybe not.

I don't know if this is the case. It might just be a setting on the board or on the transmitter. What dictates what is digital is the board, not the motor. You can run any type-brushed motor on any board because it is driving only the motor with a + and - wire. It should be no different with the new cars. The MR02 ASF has digital steering as well, the only difference is that the 03 has a coreless servo motor and the 02 has a traditional one.

With that said, I am sure that there is something you guys might be over-looking. Also, the experiment is going in reverse from what the other people are doing.

Serves you right for getting the work done at AM... ;)

How did you wire your servo to the board? The positive off the servo needs to go to the negative on the board.

I had positive to positive and when i turned it on, it jammed to one side. Sounds like thats what going on with your car.

i did swap the VR wire green to orange, my steering works fine but at "0 steering trim" my steering actually turns to left sight so in order to make it straight i need to trim a lot to the right.

If you also swapped the servo sense potentiometer wires, to fix the reverse steering, you may have the wires in the wrong order on the board or at the servo.

It's probably just the Yellow "Safety" switch on the motor (If it's a Kyosho stock or Xspeed). You need to remove the switch (The flat Yellow-Orange capacitor looking thing from the motor's power wire(s). It is supposed to prevent overheating/board/motor damage but it isn't necessary, everyone takes it off that I know.

I had to swap Green and Orange Pot wires. Wirings may look like a mess given the way I mounted the board. Board looks like it's missing something but it's not.:) Here is the90mm fun class AWD:

Just curious...

What kind of front tire do you have? Only grooved or something more special done to them?

Also, what body do you run at 90mm? The nose says 935 but if I remember correctly this Porsche is 86mm right?

Nice job anyway.

By look, I would say its two half tires on each wheel... Porsche 935 is 86mm, but easily run at 90 or 94mm.

I see few of you guys are already running the 03 board on an AWD chassis even with the 02 servo motor... So, I have couple questions for you guys:

1. is the steering crisp/precise just like the MR03? Or same as 02?
2. does is make the steering too sensitive that makes the car even harder to track straight? Or is the change for the better?

Thanks!

TJ - It's better alright kid? Just do it already...lol ;)
Answers:
1.) Steering is as good as your gonna get for the AWD;
2.) Steering is as good as your gonna get (Steering IS good).

Get'r Done woadie:D That AWD you got's just won't be pimpin w/o the RA22, I'm tellin' ya!:D lol Dude. Serious tho bro.

Yes you can:D. The thing is, you have to use the dremel very carefully and by study+piece by piece removal you could get the 03 servo in an AWD. Just time consuming. (Oh and I have not done this yet). But I've thought about it... I'm too lazy:o:eek::D

I think that people would not be able to tell the difference between a 2.4 MR-02 board and an MR-03 board if I installed it on an AWD and only let you drive forward. The difference in my opinion is in servo design not the board (except reverse delay).

Tjay
2010.12.26, 11:38 PM
The best way is to have 2 awd cars (02 board vs 03 board) bounded in one tx. Then move the steering slightly to see the difference. This is what I plan on doing when I get mine in. Ofcourse I'll have it on a video. ;) Unless someone here can do that for us already: :D

I would like to see such a test with the servo cover off, so you can see the gears as they move. Then you can really see if there is a difference. I doubt you would be able to catch that type of detail in a video, but its the best way to see if there is an increase in resolution from one to the other.

Felix2010
2010.12.27, 12:59 PM
The only thing is, EMU - TJ already made a video of the MR03 servo versus the MR02 RA-18 servo, and there is a stunning difference in "steps" of the servo action... I would think that the MA010 servo, being of the older-generation servo motor; Using the same gears (02 and MA010 servo gears are interchangeable) - That the MA010 steering cannot imitate the 03's servo+steering exactly. More likely the MA010 with RA-22 has steering similar to an MR02 with RA-22 installed: Definitely better,smoother action - But not quite the same as an MR03.

The 03 board's steering components (Fet's, etc) might be able to control the older-non-coreless servo motor better via better modulation , but the 03's servo gears, having better refinement of ratio/tie-rod movement, makes the 03 servo+steering assembly much smoother "step"-wise than the 02 and (most likely) the MA010 servo that has the RA-22 PCB installed.
Just a thought, I could be wrong about something;)

EMU
2010.12.27, 01:49 PM
I always thought that the MR02 and MR03 boards had the same steering ability, just that the motor and ICS setting was different.

What TJ wants to do is compare an RA-22 equipped MA010 to an RA18 equipped MA010. Not compare the MA010 to the MR03.

Remember, that there are quite a few adjustments that are possible with the ICS adapter, and the RA22 board ships with different settings installed than the RA18 ships with. So it could be the settings that the board ships with that make more of the sensitive steering feel that the RA22 board has in the MR02 as well. Im not ruling out that the RA22 could have more precise steering, I just dont see how it could be much different besides the settings installed from the factory.

The biggest difference of the board that I know of is the reverse delay. Which I actually like how the RA18 feels.

Tjay
2010.12.27, 07:54 PM
MR03 car has a very high steering resolution vs MR02 car. The MR02 has this 'step' while turning the wheel in small increments. Meanwhile, the MR03 is very smooth and linear with no 'steps'. This is what I want to see on an awd with two different boards (RA18/22). I just want to bench test these two awd's and see the difference in steering movement.

Its not being picky. ;) but I would like to make mistakes because of my drving rather than the car preventing me from performing my best at a race.

EMU
2010.12.27, 08:21 PM
I think what gives the higher resolution is the additional gear in the servo, not the board... I have installed an RA18 board in an MR03 chassis with some minor ICS adjustments, and the resolution looked just as smooth as the RA22 equipped MR03.

This is what I'm thinking as well, I just took the extra-long-way around of saying it...:o Although I still would not entirely rule-out that that the RA-22 unit can control 02/AWD servo's better than than the RA-18 unit, I am amazed at the difference in the 03 servo+RA-22 board.

pardon my ignorance...

so ra-18 is the 2.4ghz for the mr015/02
and the ra-22 is the 2.4ghz for the mr03?

and the only difference is that the ra22 has a different servo motor right?

RA-22 also has the extra port for the Gyro, as well as an extra ICS setting to adjust reverse time delay.

I want to use the gyro (for drifting, it's amazing...) but "ma015 rear main chassis parts" (with the upper cover) are not yet on sale.
