Black Widow Speed & Racing
« on: May 21, 2007, 09:12:50 AM »
We added 1/2A Speed and Racing to our Rouge Park Contest this May.  This was the first pass at a new lounge act.   Simple rules:

Black Widow .049, 35-foot lines, any sport plane.

Speed is 12 laps, from a running start.  Unlimited attempts, time permitting.

Racing was dependant on getting at least three successful qualifiers, which didn't happen this time.  But we won't give up.  We lost a little time due to some drizzle on our two-day contest, 1/2 A (correctly) took the hit on this weather issue.

First Place - Paul Smith, Golden Hawk, 62.8 MPH.
Second Place - John Brzys, Streaker, 60.2 MPH.

Considering the aerodynamic differences between the two planes, what the heck had Paul Smith done to his engine???
Think S.M.A.L.L. y'all and, it's all good, CL, FF and RC!

It proves out my therory, it's all in the engine.  I selected my Black Widow from several I had.  John only had one.

At 62 MPH, the difference between 40 and 74 square inches of wing area is nil.

Furthermore, with too small of a wing, the AOA goes up and the speed is actually slower.

That's actually true, been proved many times...Our big ol' 36" span .40 Rat Racer, sitting on a rail,  consistently outran those little Texas 24" Quickie Rats flitting all over the circle like butterflies...

This is not the first speed event that the Golden Hawk has won, they seem to do quite well in them. As a matter of fact it holds several trophies for speed and stunt at the Musciano contest. I feel that there are other planes in this line that could give her a run for her money.

Another factor is that the smaller "hollow logs" like my Piper Cub Special are too short.  The short body means it takes a ton of tail weight to balance it.

The Golden Hawk has a longer fuselage and mine have always had natural fore-and-aft balance with no extra tail weight.
