T2K/Webra

[Rodney Tanner]

David: The Webra is quite a bit lighter than the YS. so I would put in half inch hard wood stand-offs on the firewall. 
On my Viper, with a Webra 145, I have a Dave Brown vibramount "T" version for firewall, with an MK nose ring (OS 140 size). This the system Dennis Hunt uses on all his Vipers. Costs about $60 and works great. I intend to use this system on a balsa fuz Typhoon for an OS 140. The top half will be shaped balsa, to mount the nose ring and the bottom half of as a chin cowl, as per normal. Another option would be to forget the cowl and do the top, nose and sides in balsa and leave the bottom open, as per the Viper.

The thrust washer comes out about 1/2" shorter than the YS set-up shown on the plans. I'm building an all wood version from the plans. How should I handle this? Is it OK to shorten the cowl this much? Will it still fit on the finished fuse? Will changing the moment this much harm performance? Or should I build an engine box to compensate? Thanks for any help. Dave
