This one is more for Chazz I expect...
I'm intrigued...a 40% glass filled moulding will be much stiffer, and also much more brittle, just as you've said. I'm a consultant design engineer by trade and have been designing plastic mouldings (amongst other things) for sometime, so understand the issues you have as well
.
I'm interested to hear that on the car you can feel the difference on a wing mounted on a glass filled part and a non filled part? I'd never have thought it would be a noticeable difference!!!
I say this not because i don't beleive you...but because I'm surprised, so I'm not questioning it. My driving is nowhere near yours or your testers standards I guess so maybe this doesn't surprise me totally...and here's my thought...
The mounts look really solid in shape, and I like them for all the reasons you mention, so I wouldn't be keen to use any others. Since those of us who won't notice the difference between a 40% and non filled part are probably those of use who are breaking them more often...could it be viable to run some from lesser filled or non filled material as another option? Like the AE filled/non filled option parts.
I understand the tool/parts will behave a little differently, but if people are really finding an issue maybe it could be an economical option if the current tooling will do it? Your mould tools will love you for longer if you ran less glass fill through them too
I know from my bit of rc experience (which unfortunately is far less than my plastics/design experience...but I am working on it), I broke many B4 wing mounts early on, and have not managed to break an x6 one yet, but I suspect it'll just be a matter of time...I've not had the X6 very long!
Absolutely love the car by the way, so keep up the good work...probably only posted this because too much of me wishes I was designing for X-factory
