A small, but enthusiastic group enjoyed the season opener at the gym this week. New planes included Earl's Sopwith (or without?) Camel and my Lil Fokker - both of these from Twisted Hobbys and well suited for the small space.

A small group again this week, but a good time was had by all, with a wide variety of flying machines buzzing the airspace non-stop for three hours.

A slightly larger group this week, lots of flying, and an "extended" debriefing session at Timmy's afterwards.

October 26th

 
For those that still had airworthy models after the mid-day madness, and didn't have other comitments, the flying continued non-stop from 5:00pm - 8:00 in the gym at Grandview. Whew... What a day!

Several regulars took a "snow day" due to the weather. There was a small but enthusiastic crowd tonight - Earl, Vanessa and George. Did lots of flying though!

The highlight this week was the first flight of a vintage RTP (round-the-pole) model designed and built by Andrew Reynaert in the late 1950s - some 60 years ago!
 
Thanks to his good friend Dr. Nino "Doc" Campana, the model has been safely stashed away all these years. and after some minor repairs and a new rubber motor, it flew again this week - and what a performer! Click on the photo (right) to see the video >>>
 
The late Andrew Reynaert (his Walloon mother with whom he lived called him André) was deeply interested in aviation, so in 1939 he rushed to enlist in the RCAF to become a pilot. He qualified ground crew/maintenance. Doc mentions him in his article History of Aeromodelling in Sault Ste. Marie.
 
A meticulous craftsman, he set up a woodworking shop where he restored wooden station wagons, built boats, repaired and refinished fine furniture. He turned gumwood into propellers, sold at a quarter apiece - finely balanced and French polished (see photo above).
 
He restored cars from the tires up, dismantling engines entirely and rebuilding them to factory specs. He went to work for the Muncaster’s Canadian Tire store, the second in Canada. He became manager and when they went corporate, Andy opened Reyco Auto Supplies. He resumed modeling again in his later years. His models were impeccable.
 
He flew this model in the old YMCA on March Street, on a small basketball floor. It would not fly in a straight line due to the high torque, so he converted to RTP. Apparently, it is capable of flying quite fast, and now... having demonstrated its superb flying ability, it's time to crank up the power (increase motor size) and find out!  Stay tuned...
 
Many thanks Doc, for this info about the plane and it's designer/builder, and for enabling us to put this vintage model back into the air again after all these years!

November 23rd

 
Another busy week at the gym! The " Raynaert Speedster" was back, this time with 50% more rubber (12 starnds x 3/16" - corded) but the flights were rather eratic. The nose block (which contains the prop bearing) has seen better days, and the elevator and rudder trim is difficult to adjust. For future trials, we will address these shortcomings and reduce the motor torque.
 
Earl's micro RC Eindecker requires lots of noseweight for balance, and previous attempts to get it into the air proved unsuccessful. So we attached the starboard wing to the RTP tether and hit full throttle to see if it would fly - using some left rudder trim and elevator-only control. It flew - well sort of - but clearly demonstrated the difference between "parasitic" and "induced" drag. In a nutshell, "parasitic drag"  is caused by the friction of an object moving through a fluid (air) and is a function of the shape, surface roughness, etc. It excludes the drag created by generating lift (induced drag).
 
So... with the tail up, wheels on the ground, and the wings generating zero lift - the model scoots around the circle quite briskly. Adding some some up elevator, the model rotates, the wings develop lift, and the model easily lifts into the air. However, there is insufficient thrust to overcome the additional induced drag (caused by generating lift) - and the model slows down befow flying speed and is back on it's wheels after a lap or so. The process can be repeated over and over - by letting it speed up again, then fly for a few moments, then settle back on the ground. A fascinating demonstration of some basic aerodynamic principles! 
 
And the Eindecker? We think it would make a fine non-flying display model!
 
'till next time,
