Re: New event at USIC

The Wally Miller plans state "All Stab Wood" must be .062 sq. Does that include the rudder as a "vertical stab"? Is the horizontal stab allowed to have an airfoil, or does it have to be flat?

Thanks!

It pays to pick good wood and/or be able to find it amongst the stock you have. The other wood sizes that are not given should be up to the builder. The length is provided though.

I wonder if there should be dimensions given for the motor stick (only the length is given). Also, although the stab wood size is specified at 0.062: sqaure, no similar wood size is specified for the rudder. Finally, the prop spar is also undimenisioned in the plans as is the wing post size. Given the degree of specifications for the other parts, should not all the wood dimensions be given, if only to prevent any arguments later on?

Not much advantage to be had there with a 1.97 g minimum weight. BTW, Wally Miller's recounted history (INAV 125) proves that the spirit of EZB was very early on "how low ya wanna go?" considering that the second EZB (Wally's first) shaved 1 full gram off his son's 1.97 g prototype. Therefore, EZB is not a corrupted-by-the-experts event, and seems neither is microfilm (historically) outside of the spirit of EZB.
