Okay…..bear with me…..this blog is supposed to about all things r/c. However, if I may indulge the reader, I had the opportunity lately to view three mighty famous WW2 bombers. I felt compelled to share my experience with the big birds!

First up was a much anticipated visit of a B17G “Sentimental Journey” The Flying Fortress, that was stopping off in Hamilton for five days. If memory serves me correctly, there were something like 8,600 of this model “G” built. There are about 12 currently flying and maybe 36 left in the world. So this 71 year old bomber is quite special to see in the flesh!

These airplanes were involved in daytime raids over Germany and as a consequence they suffered enormous casualties. They weren’t particularly fast, cruise was something like 130 knots and the landing speed was around 94 knots.

B-17G Flying Fortress:
Crew - 10
Wingspan - 103’
Power - 4 x 1,200 hp Wright R1820-97 Cyclone Engines
Ceiling - 36,400 ft.
Range - 3,750 miles
Fuel consumption - 2,780 gallon per hour
Bomb Load - 8,000 lbs.
Armament - 13 x .50 calibre machine Guns

I eagerly waited at the west end of the east/west runway at Hamilton Airport and 10 minutes late, the B17G lumbered in from the north west, made a right turn and was down before it even got near me! Drats!

Next I headed to the Canadian Warplane Museum and climbed up an embankment at the rear and was rewarded with a magnificent view of the plane without having to look through the...Continue Reading

The weather was damn near perfect for our 27th Annual Big Bird Bash held at our SOGGI flying field, located south of Hamilton, Ontario. I don’t think you could ask for better conditions if you tried!

I arrived at the field around 8:30 am and was surprised to find the Contest Director, Dick C and the President, Bob H. already hard a work setting up for the event! Now that’s dedication! The only requirement for the contest was that the plane must be at least 100” wing span.

The turnout (7) wasn’t quite as good as previous years where we have had as many as 24 contestants. Normally, its a “man on man” type of contest but today due to the lower number of participants, the powers to be decided to turn this into a fun fly with the trophy going to whoever logs the longest duration flight.

Even though I didn’t have anything big enough to fly, I brought my 7/8” rubber hi-start with me. First we laid out the President’s hi-start which has been shortened to meet the requirements of our new field. Then we anchored mine right beside it to come up with the matching length. I have 105’ of rubber and now about 300’ of line. We then “dialed in” about 300% stretch on the line and brought that to the flight line and temporarily staked it down ready to be used. That amount of stretch is really the max for the lines and produces about 4-5 x the weight of the planes in pulling effort. So for the larger, heavier 3.5 M planes I reckoned we had about 18-20 lbs of pull! Yikes!...Continue Reading

What a relief it is to have the blistering hot, humid days of August behind us! This morning a couple of members joined me & my 13 yr old grandson at our SOGGI flying field just south of the Hamilton Airport. At 9 am when we arrived, it was sunny, dry, no humidity, 17 C with a light 4-8 mph wind from the north, north east.

After setting up the shade tent and work table, I tried out my latest gadget…..an anemometer or wind speed indicator. This is a really sensitive instrument and will store over 100 records. It indicates, min/max & average wind speeds and will display the results in feet/meters/sec, kilometers/miles/hour and even register in beaufort numbers for mariners. It may be overkill, but I like to know what the wind speeds are especially when it starts to get up in the 10 - 15 mph range which I find is about the limit what I can handle. Now I can take the quess work out of it and will know when to not to fly.

Next I took my 1/4” red rubber tubing hi-start and laid it out end for end. From what I have been reading on RCGroups, a stretch of 300% will give about a 4-5x the weight of the plane. I measured off the extra 105’ distance to the relaxed length of the 36 ft. rubber and placed a marker. Now at least I have a guide as to how far to stretch and the hi-start.

I brought my repaired 55” WS, “Skeeter” out for a quick toss just to make sure all was well before getting ready to launch it on the hi-start. The plan was to start at...Continue Reading
