Question about a Carbon Fiber Motor Plate

[NB25]

I'm building out an old A stamp chasis with a six gear tranny and I am in need of a motor plate. I am looking at this one:

I am trying to figure out how it bolts on however. Does it just bolt to the transmission? The original aluminum ones have two bolts in the back that mount to the chasis as well. Are these just omitted from the CF ones?

for the flat plate, they only attach to the transmission. You could make a right angle bracket to connect the chassis to the plate however. m_vice has a nice car that he made a bunch of parts for, and made a small angle bracket to connect the 2.

If you plan to run it, also consider that the carbon plate will not provide a good heat dissipation/transfer and might as well cause interference with the eletronics. I would go for a good old stock one... juts my 2 eurocents

Also remember that CF doesn't thread well. You will very quickly strip those holes during routine maintenance.

If it is tapped then it should be good to go, I have run them for years without failure ( not TBG ) and I kinda doubt his are tapped.

thats worth like 4 cents here in the US! great advice though. plus the holes strip eventually

i have had lots of problems with interference i would do the alloy to!

Thanks for the input fellas! This is why I love this place!

This is not true. Carbon fiber can dissapate heat at almost twice the rate a piece of aluminum can. The satellites I help build use carbon fiber face sheets to dissapate the heat of the electronic payloads. A search on the interenet will yield a wealth of knowledge on the subject.

Praise the Lord! non regurgitated Carbon Fiber facts!

I won't disagree, but would your standard run of the mill carbon fiber sheet use standard epoxy fillers, which would have insulating properties, vs the carbon facing in the spacecraft use having a specialized thermally conductive filler?

[shodog]

I can't get into specifics of our processes but suffice to say that the carbon impregnated with standard epoxy. It's the carbon fibers which wick away the heat. We do use thermally conductive glue to mate parts to the carbon face sheet. So I guess you could glue the motor to the plate or use thermaly conductive grease if you were so inclined.

[jwscab]

fair enough, no need for specifics.....

I just wanted to point out that usually the fibers aren't on the surface, but buried in the substrate, unlike a metal plate; although the aluminum does have a microscopically thick layer of oxide(anodizing) on it as well.

so it's pretty much a moot point.....

This also depends on the variety of the carbon fiber, what everyone in the hobby views carbon fiber to be is a asthetic top fabric-

team blue groove seems to use a CSC material, his 2mm stuff, seems to have 7 layers total, 1 CF, 1 Fiberglass, 1 CF, 1 Fiberglass, 1 CF, 1 Fiberglass, 1 CF.
