Associated B74.2D build has begun! My first 1/10 4wd buggy.

I'm already eyeballing the sc6.4

You & me both...

Well, here it is! Ready to go run at the track hopefully next weekend!

Sweet ride!

Are the edges of the carbon fiber parts sealed? The shock towers would be my biggest concern.

What do you seal them with?

I think @RustyUs is meaning this. Snap shot from a Xray manual as I don't believe associated mentions it in their manuals. At least with my .1 they didn't, which is odd.

You can glue the towers to seal the layers together so they don't come apart.

Wish AE put this in their manuals so I knew about it earlier. If I had knew I wouldn't be running an aluminum front shock tower on mine probably. Lol.

 

[ferrebee88]

Well, I guess I will add that to the final checklist. Thank you.

Sorry, I don't get on the forum as frequently as I used to. Nowadays, I'm out playing with my toys while the weather is great. I thought most manuals used to mention the use of CA glue to prevent delamination like that Xray manual that David posted. Maybe I'm making that up. I don't know where I picked it up from about sealing the edges. I just do it every time I see the stuff. Maybe I'm just paranoid.

Yea I just checked my .1 manual and they didn't mention anything about gluing carbon parts at all. I guess it's just a older Xray tradition (bc my snapshot is from my uncles wheeler from 2017 soooo... lol)

Wish I known it before. Still running the stock rear CF tower on mine and in the top corner the layers started to separate. I guess it happened when I crashed/landed wrong but it is what it is. Used some glue and its holding up just fine.

I sand and glue my CF edges too.
I think I got the idea from FRP parts from Kyosho decades ago.
I will ask fiberlyte since I have an order in with them anyways.
I am very curious to know if gluing is recommended by them or no.

Stephen Walton
Hansell Composites Ltd (fibre-lyte) says...

'...other people have been doing the same as you for decades as well.

the reason why people started doing it was indeed to stop the edges of the parts delaminating during an impact. It really only applies to prepreg (mass produced) parts as the amount of resin in those parts is minimised and the only thing keeping the layers of carbon together is the resin. Our parts use a different process, have more resin and therefore are less susceptible to delamination.

does it work - may be. Is it necessary with our parts - no. Would I recommend it - it certainly doesn't harm the parts and when done well, it smooths off the edges and can make the parts slightly more appealing. If you can be bothered with the messing around and prefer to do it then why not. It's certainly not necessary though...'

That makes sense to me. I know a guy who got into manufacturing carbon fiber handlebars for road bikes. I've learned through watching him that it's a far wider and more technical world than I ever imagined.

I also know he's looking for new projects. The market for high end bike parts is a bit weak. If anyone out there wants a guy that can build custom carbon fiber parts, just let me know and I'll pass you along. He recently picked up a contract to build fairings for an ultralight aircraft kit.

I finally made it to the track this morning. This buggy is awesome. My driving skills are lacking, but it handled very well. Very well planted and easy to control.

 

[ferrebee88]

Just got around to the second track day. I am so impressed with how this buggy handles in my inexperienced hands! The track was really damp and slick, but man I had a blast.
