General Discussion / Warning - electrical issue!
« on: December 16, 2018, 08:17:17 AM »
Recently, I "repackaged" my Optera (reminder to self, when you take your eyes off a white wing at high altitude, even for a couple of seconds, you may not be able to re-acquire said flying object!).

When I was removing the hardware, guess what I noticed at the spinning end! (Photo attached)

This particular situation could exist on any installation but may be difficult to detect. In the case of my Optera, which was 2 or 3 years old and well used, the leads from the motor must have been jammed into place at the time of assembly. One of the three was rubbing against the rotor, resulting in the wearing away of the blue anodizing and, more importantly, the insulation and underlying wire, being worn down.

Now, this poor installation could just as well have worn down more than one of the three wires. Had that been the case, something bad would have happened. In the worst case, fire! In the not so bad case, the ESC and structure itself would have been demolished. LiPo fire, anyone?

Although this was a factory installation, buried well within the aircraft's structure and impossible to see without major disassembly, it could happen with other setups.

One lesson that I have learned is to carefully inspect any initial installation prior to first flight - if at all possible. You are usually dealing with a very high energy density system.

General Discussion / Apace - the final frontier
« on: December 13, 2018, 12:08:12 PM »
It's getting closer, at least for those who have some serious coin. Here is the latest development, where SpaceShip 1 officially reached space (non- orbital ,of course, but pretty good anyway!). The accompanying video is excellent, you get to see inside the hangar, in flight, etc. Enjoy!

Wouldn't it be a nice group project to build a model of the mother ship and the space plane? We could pretend that "outer space" starts just a half dozen trees high, right? Awhile back, Andy Kunz of Spektrum fame, built an r/c replica of one of the NASA lifting bodies. Although not all that great in flight, it was a really cool project.

General Discussion / Flying the big jets - from a test pilot's viewpoint
« on: December 07, 2018, 09:13:15 AM »
For anyone who is interested in big aviation, test and certification flying as seen through the eyes of the best, here is something to enjoy. The podcasts are long but certainly not boring! I download them onto a thumb drive, phone, tablet, etc., to enjoy while waiting for an appointment or while puttering in the shop.

“The test pilots’ test pilot”, former CAA Chief Test Pilot D. P. Davies talks about his early career first training and then serving in the wartime Fleet Air Arm, including reminiscences of the naval test pilots course, the Empire Central Flying School at Hullavington and the Handling Squadron. He recounts flying the Fairey Swordfish, Fairey Barracuda, Blackburn Firebrand, Grumman Avenger, Hawker Sea Fury and Supermarine Seafire. During the post-war era, he was "the man" whose word was the ultimate in accepting new aircraft into British service.

I bought his book
Handling the Big Jets:
An Explanation of the Significant Difference in Flying Qualities Between Jet Transport Aeroplanes and Piston Engined Transports

way back in 1973, as a byproduct of interviewing for a job at the NRC's National Aeronautical Establishment.

Although directed toward air transport pilots, it is quite readable for others and remains an extremely popular book amongst the originally intended audience. It is still available through Amazon. I could never have imagined that, 6 years later I would have a future air transport pilot and production Dantest pilot in my family. He found this book to be very useful in his flying career. The down side is that some of his cohorts have also found MY copy to be useful and I am having a difficult time reeling it back into my collection!

Good points!

Suggestion:
So, you can keep it secret up to the completion of the maiden flight, which must be witnessed by someone, but then you have to poney up with the appropriate proofs. Comments?




21
Proof required!

 Must post, RIGHT IN HERE, at least 1picture prior to the maiden flight and another after that flight.
Extra brownie points for a video of all or part of a flight.
Even more kudos for a write-up and/or pictures of its construction.


Remember:

OK, Reg, the contest is sort of under way. DuWayne thinks it is a great idea - so, let's see if he puts his (money? glue gun?) where his mouth is.  :P  :P

I will soon post a really nice picture of my initial entry. It is/was a beautiful design! I used the traditional TLAR approach, trying to end up with a TFAR machine. We fell a bit short of the objective. I had one flight, it was pretty hairy at first, I got it tamed down somewhat but decided " enough is enough".
So, I carved it up into little pieces in order to recycle the hardware into my next entry - the X-41. Stay tuned.

As for the contest itself:
 
 Should we have a kick-off session at one of the local watering holes?
 Do we allow and "secret projects"? Or, do all entries have to be revealed prior to First Flight? (That could be interesting, just to see how delusional the designer/builder is.)
Where will the awards banquet be held?
Will there be cake? (We already know you like chocolate, Reg.)

VIDEOS and PICTURES from KRCM Events and Activities / Mutley
« on: November 24, 2018, 10:57:15 AM »
I have been an ardent fan of Dick Dastardly and his dawg, Mutley, for many decades (Growing old is manditory; growing up is optional. I rest my case.).

So, several years ago, I created this little monstrosity. It flew well, much better than it appears on this particular day in the howling wind. The cartoon world offers a lot of ideas to those of us who seek out new frontiers.

Ok, Reg, you asked for it!


IT IS ON!  :P  :P  :P

I have a couple of uncompleted Unidentifiable Flying Objects, very Flypaperish in nature. I am immediately resuming work on one of them. The glue gun is HOT.

As for "rules"  :o - we don't need no stinkin' rules.  None of Gordy's UFOs looked like they obeyed any rules, did they?

FPV at KRCM / Skipp(er)ing Around The Bay
« on: November 21, 2018, 06:48:42 PM »
Here is another little video that I cobbled together. It features that wonderful little all-terrain, all-season, all-weather flying machine from HK , the Skipper. Roger has the same model, which he purchased from Great Planes - they call it the Dragonfly. This flight took place back in "pre-windmill" times out here on the rock.

I have flown the Mobius on it but have not yet done full FPV. That may happen as soon as this weekend, as it is one of my "winter" planes. I only have to clip the Mobius into its 5.8 GHz transmitter case and pop it onto the plane. My reason for not trying full FPV already is that I have lacked confidence. Although Skipper has NO bad flight characteristics and can be slowed down very nicely, it may still be more of a challenge than the Fun Cub or Penguin for a low time FPV pilot like me. As well, the spotter may have difficulty in keeping track of it due to its smaller size, minimum profile and ability to cover a lot of territory rather quickly. We shall see ...

 Meanwhile, here is the video. The aerial portion seems rather jerky; perhaps, I had the stabilizer Gain a bit too high or perhaps I had the stabilizer turned Off, I cannot remember.

VIDEOS and PICTURES from KRCM Events and Activities / Muddy Red Baron
« on: November 18, 2018, 09:26:02 AM »
 I have been sorting out a ragtag collection of video clips and trying to make something out of them.

 Well, here is one that brings back some fond memories. It is hard to realize that Gordy has been gone a whole year now. His "Muddy Red Baron" speaks a lot about him. I reckon that assemblage of airborne material logged more air time than anything else at our field, over a period of several years and many reincarnations. Wings, struts, cowl, tailfeathers, fuselage - they all saw a lot of hot glue and/or were swapped out for "enhanced" versions. The guy got more fun out of flying than anyone I have ever known, and this particular craft was perhaps his most prized toy!

So, without further delay, here is The One And Only MUDDY RED BARON!

FPV at KRCM / Opterra FPV - March 2017
« on: November 16, 2018, 11:01:02 AM »
I discovered some mislaid video clips where I had popped the Mobius into its 5.8 GHz vtx and stuck it on the Opterra. Here is the cobbled together video that resulted. No music (too bad), no commentary by me (perhaps a good thing?).

General Discussion / Real Float Flying
« on: November 13, 2018, 07:01:05 PM »
 I made the following video for family viewing but some of you KRCM folks know the Pilot and First Officer. The actual takeoff occurs around the 3 minute mark and it is rather impressive to see from my vantage point. In case you wonder what the Pilot is doing wandering around on the floats: part of the pre-flight after extended water time is to check and, if necessary, pump out the float compartments - there is always some condensation and/or minor leakage and you don't need to be carrying an extra couple hundred pounds around. (That was my job when I flew with him; Miky was not yet trained up on that.)

https://youtu.be/Ncx-jUTGLb0


At the time this video was shot, Dan had a minority partnership in the airplane. His client, a financier for whom Dan flew the Gulfstream business jet, acquired the plane and Dan flew it for him. Most of the routine flying was between Billy Bishop Toronto City Airport ( YTZ ) and the client's summer "cottage" up in the Muskokas - a one hour flight vs. 5 or more by car.

Dan used to fly into our bay, where I had the temporary mooring, sometimes staying for a day or two, usually accompanied by his First Officer. Mikayla. This usually involved a 20 minute hop from Buttonville, where the plane was hangered, over to St. Catherines to pick up Miky and then about an hour and a quarter down to our place. She had her own Log Book and did some of the flying, including gentle turns and other fancy stuff!

 This is a Cessna 206, often referred to as an "all terrain" aircraft. These are widely used as a bush plane, skydiving jump plane, and personal transport plane. It seats six, has double doors for passenger or cargo handling and is very comfortable.

This plane has very modern instrumentation, including autopilot. Its 310+ horsepower engine and the Wipline amphibian floats equip it well for zipping in and out of confined areas. Dan installed the STOL kit, consisting of a large number of vortex generators on the wing upper surface and under surface of the horizontal stabilizer, which significantly lower the stall speed and thus enable better takeoff and load carrying capability.

FPV at KRCM / Fun Cubbery at Preston Cove - June 2015
« on: November 12, 2018, 09:53:17 AM »
 I got a Mobius camera, mounted it to the wing of my FC and put up some flights around Preston Cove.

https://youtu.be/9GCO8XZHJF0


 Takeoffs were to the East, Lemoine Point shoreline is about 5 miles away - plenty of runway!

 As we swoop down into the bay, you may notice the white floats - they mark the temporary mooring where Dan used to park the Cessna 206 floatplane when he would occasionally drop in. In the winter, if we get sufficient ice, there is a month or two of great flying of my models. So, this really is an aviation base!

 Visibility was unlimited that day; however, there is not a lot to see in the distance. The most noticeable item over on the mainland is the smoke from the Lafarge cement plant; today, it was fairly white, but a lot of the time it is very dense and dark. You may get a sense of what Amherst Island is (was, before the invasion of the windmills). The interior of the island is mostly open farmland, pastureland and a few buildings. Lots of room for those nasty deer to operate; they are as thick as flies over here!

 My nearest neighbour is the farm that you see just after takeoff. The only other nearby establishment is the house up on the hill (white roof, greenish siding) which is maintained but has not been lived in for several years.

 You may notice the large, now decommissioned,  quarry just down the road from me that used to supply all of the aggregate for road maintenance on the island.

 As we approach into the bay there is our 150 year old white brick schoolhouse, mostly hidden behind the trees. Then, there is our house, also white, with the deck where folks can watch the airshow (I have to pay them, not the other way around).

 Twenty some years ago, the Tall Ships event took place and we were amazed when they ALL showed up in our bay for an overnight stop. What a circus! Lots of power boats milling around and gawking, a news helicopter, we sat outside and watched it all. I wish I had today's camera technology on my well-used Seamaster back in those days.

 In the Good Old Days (think Prohibition as well as the 1812 war), this spot, along with some others on the island, was used by some rather interesting folks conducting their business. I still hope to find a well-aged case of hooch washing up on the shore someday ...

 One of these days, I will take my FPV Penguin up to one of my secret aerodromes and do a survey of part of the island, now that it is dotted with the 26 wind turbines. So, this video, plus one done via my Skipper all-terrain airplane, is the last look at our island in its former state.

General Discussion / Airships, Oxen and other interesting stuff!
« on: November 05, 2018, 09:31:28 AM »
This fellow, who calls himself the "engineeringguy", has some terrific videos out there. His website is    http://engineerguy.com/

This video, about the great British airships, answers a number of questions - at least for me. I remember my mother telling me about seeing the R101 when it visited Montreal.

The mere size and engineering challenges associated with these things is incomprehensible to folks these days. Many of us have seen one of the Goodyear blimps; these are mere toys by comparison to the British and German dirigibles.

One of the myths surrounding the demise of the Hindenburg was why the Germans used highly flammable hydrogen rather than inflammable helium. It was not that other countries would not supply helium to them, it was largely due to basic physics of lighter-than-air vehicles, as is explained in here.

Incidentally, there must have been a lot of oxen that rested easier when that whole industry collapsed!
