Indoor Updates: September thru December 2018

September 28th - Northern Community Centre

 
WOW look at all that flying space !!!
 
The first 55+ indoor flying session was incredible! Can you believe it? We had half of the indoor soccer facility to fly in. Stan, Steve Daly, Earl, Clarence, Peter Smith and myself flew for two hours in "pure ecstasy"!

Compared to a hardwood floor, the artificial turf requires larger wheels - such as those on Earl's Sopwith and Pietenpol, to facilitate smoother take-offs and landings without nosing over.

With the advent of a larger surface area and higher ceiling height, we will be allowed to fly larger electrics with a maximum wing-span of 1 metre (40 inches). I can hardly wait to see what the next session has in store!

'Till then, "the flying fool"...

October 5th - Grandview Public School

 
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.

October 12 - Grandview Public School

 
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 26 - Northern Community Centre

 
Our second session at the "indoor turf facility", and what a time we had!
 
Participants included Cec, Clarence, Peter, George, Vanessa, Earl, Greg F., Norm & Chris.
 
Earl almost scored a goal with his Sopwith (or without) Camel, and Cec learned that an "outdoor" plane is a handful when flown indoors - even in this large venue!

October 26 - Grandview Public School

 
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!

November 9th - Grandview Public School

 
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!

November 16th - Grandview Public School

 
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 - Grandview Public School

 
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,

November 30 - Northern Community Centre

 
Our third session at the "indoor turf facility" and lots of R/C flying of course! Always keen to try something different, Chris and Earl brought a pair of control line models, and both flew successfully on 36ft lines. Pilots holding the handle at the centre of the circle this week included Chris, Greg, George, Vanessa, and Earl. We haven't flown control-line indoors since 2012!   <<<video here >>>
 
When Chris emailed me on Monday with the idea of "slapping together" an indoor control-liner for Friday, I initially thought of bringing my FT foamboard Pietenpol out of retirement, but realized all my models were high-wing with a fair amount of dihedral. What I needed was a straight – midwing design.
 
I happened to have a copy of Sport Aviation on the coffee table with a picture of an aircraft called a “Midwing Special” on the cover. This was a Piper PA18 Super Cub, with the top cut down, the wing clipped, and mounted at shoulder-level - single-seat, open cockpit, and ideal for performing at airshows. The light bulb in my head went on! I had previously built a FT foamboard Super Cub & decided to borrow the power-pod (FT “C” pod, consisting of an Emaxx GT2215/09 outrunner motor, BL Heli 30 amp ESC, and 10”x4.5” propeller with a 3 cell 1350mAh battery) and landing gear (since the super cub was currently on floats) and just build a new airframe from a couple of sheets of Elmer’s foamboard.
 
midwing
The wing ended up with a 30” wingspan (the length of a sheet of foamboard) and ½ inch trimmed from the chord. Starting with the Simple-Cub plans, I shortened the tail by 1 inch and moved the wing down to just above the power pod & forward ½ inch. I also moved the landing gear ahead ½ inch & re-drew the fin & rudder to match the picture in the magazine. A bellcrank attached to the elevator horn, a windshield, and turtle-deck  - and that was it – a couple of evenings of relaxed model building. I was really happy about the way it flew, although I need to study up on phugoid dynamics as it doesn’t really want to fly straight & level, especially when the power is more than about 2/3 throttle.
