FPV at KRCM / Some FPV Ramblings
« Last post by Deerslayer on April 14, 2018, 11:36:18 AM »
Attached is a summary of some FPV-related stuff I have been doing. I hope it give someone some ideas, or can start a discussion.

It surprises me that Flypaper never showed up with one of these ... or did he?

KRCM Flight Training Course & Training Nights / Re: Wednesday night dinner

Hi folks,

The days are getting longer but the weather has yet to warm up. Ideally, I'd like to start training by the end of April but that of course depends on Mother Nature. I will keep you informed once we have a date.

That will be decided by Jay, but it probably won’t be until the evenings are longer and the weather stabilizes.

VIDEOS and PICTURES from KRCM Events and Activities / Levin's Hotts
« Last post by Deerslayer on April 12, 2018, 08:38:46 AM »
Harold and Levin have been at it again! They dug out what is claimed to be a Hotts sport airplane from way back in time, cleaned it up and fitted a new ASP .46 engine.

Back some 30 years ago, the Hotts was  at the top of the heap of fun flyers. Dan Santich designed the original one, followed by the Hotts II (two) and Midwest kitted it as one of their superb Success Series offerings. I had one of those and it was the most enjoyable kit I ever built, before or afterward. It was a terrific flyer and I would love to find on of those original kits to build again.

There were many variations of the Hotts that were created over the years, several of which even showed up in our Club. Giant scale, intermediate, biplane, SPAD, foamy, too many to recall.

This particular plane most be scratch built, as i has foam sheeted wings, no plywood sides or turtle deck and its fuselage shape differs from the angular slab facets of the original Hotts. The wing tips do not have the end plates which were very critical to taming the behaviour of the original Hotts II. But, who cares, let's call it a Hotts and see how it flies!

I was pleased to take it for the test flight. Wow! this thing really rocks and brings back some memories! After a quick try, I cranked in about 50% expo on the Ailerons and Elevator, eventually bumping it up to 60% on both after we did the second flight. We called it quits, as the wind was howling. I left Levin with a couple of suggestions, such as relocating the battery to move the C of G further back.

As this was the first flight for this plane and engine, in our hands, and it was a very windy and gusty day, I did the takeoff and the eventual landing. Levin took over in the air, once we got a bit familiar with it. He will have to be very careful, as it is a step change from the average airplane that scoots around these days but he is very capable of handing it.

Some of you may know Levin, a.k.a. Flight Kid.

Apart from hanging out with us and flying, he leads a very challenging academic life. Recently, he participated in the regional Science Fair at Duncan Macarthur Hall.

Harold and I were privileged to obtain a sit-down VIP visit with Levin at his display. We were unable to stump him with our questions; he really does know what he is talking about!

Levin's project was the laser CNC system which he designed, built, programmed and documented. His dad helped with the cutting of the wooden components and perhaps in the de-bugging associated electronics, but L learned/utilized the GRBL programming language and all of the other associated technological aspects. The device works, although he was not allowed to activate the laser at the Fair, due to safety requirements, quite understandable, even though he currently has only a 5mw or such laser from a CD drive. He plans to purchase a higher powered laser and be able to cut foam for ... guess what ... flying machines!

I suggested that he bring his travelling road show out the to field sometime this summer (perhaps at the FDFF) and display it.

Harold and I were really impressed with the tremendous efforts and variety of projects at the Science Fair. We walked away feeling really positive about those who will be the future Engineers and Scientists and leaders. Great work and Good Luck to all of them!

Perhaps our guy will choose to comment in here, with more explanation, if he ever gets some time!

Meanwhile, here are a few pictures taken at the event.

VIDEOS and PICTURES from KRCM Events and Activities / Marvin the Digger!

Well, guess what I found out at the Toyground! (Pictures attached.)

Grasscutter was rootin' around with a digger that he "borrowed" from ... don't ask! So, what is he up to? Well, he started out strip-mining an area just east of the building (there is only one building now). He seems to have hit bedrock before encountering any gold or human remains.

You never saw a guy so happy as this fellow playing around in the dirt. By the way, who would have guessed that there is actually some high quality soil between the grass roots and the rock around here? Look at the giant pile!

His next step was to call in a load of crushed stone and start filling the hole up again.

So, what is he really up to?

This is the first step of expanding the dining/observing area. A concrete pad will be poured and, if the money doesn't run out, the clubhouse overhang will be extended over it.

This will provide a very nice shelter for the Peanut Gallery, as well as a place to set up or work on planes, as well as to prepare food and eat it.

KRCM owes Marvin a hearty thanks for scrounging up the excavation equipment and knowing how to use it.

As I was leaving, Mike was on his way out with a surveyor's level so that Marvin could begin the levelling and tamping of the stone. (It looked to me that a couple more loads would be needed to establish the base for the 5 inches of concrete to cap it off, so he may be at this for awhile yet.)

Marvin - how about an update?
