I'm after a carbon replacement undercarriage for my Monolog 70 and not sure where to start. I would try Carbon Copy, but I've bought from them before and it was a bit too chunky for my liking. I'm looking for a suitably skinny one to reduce drag. Anyone got any ideas?

I was looking for a carbon fibre undercarriage for my electrified Acro Wot to replace the alloy one.

The CF item actually weighed more than the original.

Whether the drag reduction of any flat or airfoil section over a round wire would be significant unless extremely thin would be difficult to measure................................and any advantage could be offset by the extra weight.frown

Sorry, i'd forgotten to say that the current wire one had been bent a few too many times on landings and the mounts had broken after i'd bent the u/c back one too many times. I've now replaced it with a wire one i'd forgotten I had like the ones in the top pic here. Cheers folks

I do know of a flyer here who replaced their UC on their biplane and quickly replaced it back to his wired version as the carbon UC was far too bouncy.

It may well be that it is your landings that need attention rather than the UC? wink

Chris was the heavy one a carbon copy offering?

Yeah, like I say, I went to CC before and it was a big chunky thing. I know other people make thinner ones, I just don't know where to look

Chris that explains it then. CC undercarts are best described as cabon veneered glass which explains why they're so heavy (ie they're mainly made of glasscloth with one layer of carbon cloth on either side for bling) . A proper carbon composite one would be considerably lighter.

Not that there's anything wrong with a glass undercart, if that's what you want. It also explains why CC's carbon finish and glass finish products are the same price and weight.

Weston used to make carbon U/C for their Hype product, not sure if it's still available.
