Hi Ivan,

Very interesting and simple chassis. A bit of a drawback that ASC's can't be used out of the box, but I understand your design priorities in not supporting them. It will definitely hurt your sales if you're planning on releasing the chassis commercially though.

I'm very interested in the steering linkage and tie rods used. Can you provide some further info (part #'s?) and perhaps some more closeups of your solution?

Thanks and great looking car!

Ivan, adding a top spring should remove the on-power oversteer, it'll load the rear tires a bit more the moment you pull the trigger. Overall car looks good, I'm curious about that tierod you have.

Thanks Brian, I will try with a top damper but before i've to design one because the space is very small for a standard one.

I'll put some pictures of the steering system during this week, is much more easier to show it than to explain it.

Regards.

As promised, here there are some new photos.

I put a rear damper made out in a very simple way using some parts from a stock kyosho damper and DPS Atomic springs and it works great! Thanks Brian for the idea.

About the steering link as i tell before is a very simple thing: I've used again two ball connectors from kyosho stock dampers, M2 threaded bar and heat shrink to cover everything. I made a 1mm hole in one of the ball conectors and using a Z shaped 1mm piano wire i connect it to the servo. That's it!
Of course, now is time to improve this system and i will put a longer L shaped piano wire in order to link the farest ball conector to the servo arm with a micro linkage stopper.

Note: the ball connectors that i use are some Atomic 4.1mm spare balls and ball connectors that were made for XRay M18 car but is easier to get the ball ends of kyosho stock damper right now and it works well.





Ciao

Cody, he has made a mount that accepts the Kyosho MR02/015 t-plates... it screws through an extra piece on the chassis... which is screwed in to the main chassis with the 2 screws that are in front of the t-plate and 2 screws that are between each pair of batteries. You can see this in the picture of the bottom... It looks like a nice design.

I believe that the damper post is also attached to this t-plate mount...

Thanks EMU for your explanation, it's exactly like you said. I'm not very good explaning myself in my mother tongue so imagine what happens when i try in english :-)

Whatever, here there are a couple of images in wich you can see better how is it.

Behind the t-plate there is a normal 02 triangle mount that is used to separate the t-plate form all the other surfaces and to leave it free for movement (like a MR-02 or 03).
Behind the triangle mount there is a "big" carbon fiber T that is secured with four screws to the main chassis and that is what i've called the t-plate. This t-plate mount is full of holes as you can see in order to use all the MM wheelbases just moving the screws, there is no need anymore to change motor-mount or DPS.

The last thing that i added to the proto is a last "layer" made out of 2.5mm alluminium that makes easyer to replace the t-plates in an easy way and helps to hold the DPS post. Before the screws that hold the t-plate were tighten with normal nuts but it was quite complex to change it so i decide to go in this way... This alluminium piece is hold with two screws to the t-plate mount when the t-plate is not installed and with 4 screws when the t-plate is on it. I think is a very tought system.




Thanks for seeing!

Best regards

I'm glad to write that one of my MP-V4 has arrived to the US to participate in the Tekin National Race.

I hope Z_408 will inform us about any updates or news about it :-)

Ivan I have been following your work. Love everything you get into. I was just wondering if maybe you could start a thread on your lexan wars chassis.

Or ifyou could just post a couple more pics and specs of the car. I have wanted to do something like that for a while.

Cody

I heard the same thing from Binh yesterday as I dropped off my MRCG1.1 to be raced. Looking forward to pitting our cars against each other!

Hey Ivan I got to see your chassis at Z_408's shop.. it is extremely nice.. the one thing that swtuck out to me was that the balls and pivoting joints (servo saver + shock) were binding a lot.. that can easily be fixed but I would look into making a production run of them. It is very simple and can use t-plates and motor mounts.. that is awesome.
