Hello there... I frequent the Extreme Speed forum and think it's high time to update the sub-heading for that forum. The Whiplash is no longer in production and no examples of this plane are being shown any more in dedicated threads.
The plane that should be inserted into the sub heading is the Screamin' Demon. It is the dominant purpose built speed plane being shown in that forum and dozens of these kit built planes are being flown now. If this forum is to grow, this is the plane that needs to get top billing.

Thanks for considering this request.
