Controline Endurance Record Trials

Rice Mill Flying Site on Sunday April 26th, at 11:00 a.m. 

Yesterday, at Rice Mill Road flying site, Henry made an attempt at the current MAAC control line endurance record. The current record is held by the late, John Bortnak of Alberta at approx. 1 hr.45 min.

To help understand the complexity and convolutions of such an attempt, I have including the rules as provided by The Balsa Beavers of Toronto -http://www.balsabeavers.com

The plane is a 182 Cessna Skylane which is in part modeled after Henry's brother's 1962 Cessna Skylane and therefore included his Canadian registration C-Ghey on the side and wing.
The engine is a CS-15. with a 24 oz. R/C Clunk tank we ran on suction only due to problems with the muffler attachment. 

Henry made a "test" flight on Saturday. Here is his report.

" I am pleased to report that the test flight scheduled today at Rice Mill Flying Site - was successful. We managed 10 laps on the secondary fuel tank and the plane behaved very much like a Cessna 182 should. 
Without aileron assist and the engine running steady on the test propellor 8" x 4" P. Rpm 11,300 the plane was in the air within a 1/3 of a lap. Some adjustments will be made for the official flight including the addition of the muffler /pressure with fuel capacity at 24 oz. Estimated Flight time is a potential 3 hrs. plus"

Unfortunately things did not go as well as hoped. With plenty of assistance on site - for pit crew, record keeping, and banter - from both PAC and VGMC (Vancouver Gas Model Club) Henry's first attempt lasted 6 min. 40 sec. and the second attempt was an improved 11 min. 38 sec. The engine turned rich on both attempts. On the second flight it, combined with an increasing breeze, caused the plane to come in on the lines. To save the plane Henry had to step outside the 5 foot radius (9.9 below) therefore ending the attempt even though he flew for an additional time.

In future, Henry will install Paul Bedford's recommended R/C Perry Pump fuel system which will produce an even run throughout.   Henry will reassess, make other alterations and adjustments and return for another attempt this autumn.

I have 1 photo - of the airplane - with hopes of more from Dennis & Paul.  Here is a short video from the early part of the flight by Joe Yau
