Hi Topend,
Thanks for the reply, can't wait to hear back when/if you manage to chat to the chaps. The price isn't so much as issue as the cost of a Beta + the upgrade will give you (Theoretically) a Beta II for a good few bob less than straight out buying a Beta II from what I've found. Likely with better hours too!
Which is why I'm so skeptical, seems like it should be something every Beta should be equipped with and yet they don't seem to be nearly so prolific. I've flown one, which was also the only one I've ever seen/heard of, fitted with the exhaust but that was just after completing my PPL. I was one up and I also didn't have the experience yet to notice any difference in power.
Haha, that does indeed sound like a sight worth seeing and I wonder how long the other 47 lasted doing tourist work. One wonders why they didn't bother putting an exhaust on
Regards
Devon
