IMO go flat not ribbed, yea it will look cool for the first 5 mins but after its bashed a little all thats gonna happen is it will look a real mess when its been stoned chipped and chunked out. Plus where its countersunked holes will look messy and catch on stuff. Smoother the better I reackon for a chassis.
Make the chassis the same length as the magnum and use its top plate, buy the magnum (plastic) brake seat so you have the mounts for the top plate, with this you can add the lay down steering servo mounts to it. IMO the aluminium brake seat is overkill with a top plate (and freakin expensive!) So those with a ali brake seat either sell it on the Bay or make a 10 min bracket with a piece of bent ali and drill and tap a couple of mounting holes to join it to the seat.
I may have said this before but making a really good top plate can not be done with a flat piece of ali as it provides difficulties in mounting the throttle servo, and IMO mounting a servo up through the top plate is not the desirable option.
Why make something thats already done?
In saying that why make a new chassis at all when you can go out and buy the Magnum ONE piece chassis, CEN have addressed the issues of chassis flex (by the looks of it all, I dont have one) with the Magnum so its just a case of getting those parts for your MT2.
Dont make things harder than they have to be...
Hey guys JMO ok.
