LOSA8117 wing set help ( front on a xxxcr)

[stulec52]

Picked up this wing set, but I just can't see how it fits, or where to cut it.
The rear is fine, but I wanted to try a front.
any pics or help would be great !

thanks

If you don't have a XXX-CR you need the Losi High Downforce Wing Kit (LOSA8110) which has the mounting kit in it.

I have a used cr which I don't think has the kit, although I really wanted to put it on my original xxx.
SO, 'need' the mount kit, or could it be made with something I have already?

Thanks
