Upcoming Events at KRCM and elsewhere / Re: Warbirds Gathering - Mass take-off info
« Last post by Rene on July 28, 2017, 06:36:09 AM »
This event is for .46 size warbirds, examples of these are the hangar-9 P-51, P-40, VQ Mustang, Hurricane and Yak, etc

The aim of this event is to do a mass flyby, no aerobatics, just circuit flying while attempting formation

The Event Coordinator will do a briefing around 1245 Hrs with the intent of Taking off shortly after


Take off procedures: It will be in succession, this means one plane after another with a couple of seconds in between. 

Circuit will be done following and identified “Lead” and will be done one behind the other, maximum of 2 in line abreast at all time.

Landing procedures: landing will be done individually, pilots are required to land long and exit the runway on their own power passed the flight line. No recovery of airplane on the field will be done until the end of the event.

Risks:

The risk for accident is relatively higher than normal flight, therefore:

If you don’t feel up to it, stay on the ground, nobody will judge you

Any low pass over the field must be no closer to the pilot stations than the centerline of the runway

Calls Definitions:

Inside mean close to the flight line,
Outside mean close to the wood line
On final mean you are committed to landing
Backtracking mean you are taxing back in front of the pilot stations

Each pilot has the option of having a spotter. The aim of the spotter is to track his pilot airplane and to ensure safety calls are made.

It is the responsibility of the follower not to collide with the lead.  Any avoidance maneuvers must be done “away” from the Flight line.

Upcoming Events at KRCM and elsewhere / Re: Warbirds Gathering - Safety points
« Last post by Rene on July 28, 2017, 06:27:19 AM »
Safety points for this event are as follows:

In order to make things simple, There will be a white board describing circuit orientation, field constraints and restraints.   

The Staff for the event will wear bright yellow T-shirts.  They have the last word…

Starting of engine will be in the pit area only, All airplane must be started under some form of physical and safe restraints.  All electrical airplane must have a working safe arming and failsafe system.

Each pilot has the option of having a spotter. The aim of the spotter is to track his pilot airplane and to ensure safety calls are made.
We will use only the 5 flying positions on the inside stations.  Outside stations will not used (they will be closed).  Therefore, the limit of number of Flying Aircraft will be Only 5 Aircraft in the air.

Do not stand and fly in between flying stations.

There will be no use of North/South runway.
            
Need a mandatory spotter only if you are doing dogfight.

No 3D stuff or Helicopter or drone hovering over the Runway.

Mandatory Standard calls apply at all times (“taking off”, “landing”, “deadstick”,” On the field”,”backtracking”).

Full scale airplane have priority, anyone spotting a real airplane must advise the flight line loudly of the position of the real airplane in order to take necessary safety measures

I hope this will answer the "General's" concerns

BLUF, There is a good communication plan for this activity

We currently advertised at Leading Edge hobbies and posters are also placed at the club house in order to raise awareness of the event.  There will also be a mass e-mail sent out a month or so prior the activity that will be sent by the club executive.

The underlying organizational theme for this event is simplicity as well as fun for the club membership, basically, we go there to fly  :D

As for news coverage, I would offer that it would be better to get them during the giant scale weekend, way better venue and attractions.   :o

Cool, thanks for posting.  8) ;D

This is the concept which attracted my attention:

https://youtu.be/9xjHCHR5_50

I have now flown my store-bought X-VERT a number of times, with vertical take-offs, transitions, full horizontal stabilized and unstabilized flights and vertical landings.

Now, back to my own Tailsitter!

I have decided to take a different approach to the VTOL modes. We are returning to vectoring the motors and eliminating the vectorons. This time, the motors will be vectorable to almost 90 degrees "up" and about 10 degrees down.
Takeoffs will be with the fuselage lying horizontally, motors vectored vertically to pull the nose up and lift the body, with transition then occurring rapidly by holding the motor thrust vector close to vertical while the fuselage rotates to inline with the motors and begins flying. This plane has the necessary much greater than 1:1 thrust to weight ratio. Landings would be the reverse of this procedure. Again, there will be no flight controller involved. I still have to resolve the issue of assymetric thrust, possibly due to motors not synching at intermediate portions of their range, resulting in hairy/scary launches.

Hopefully, testing will resume next week, along with video - disastrous or not!

Plans, Projects and Building Tips / Re: Hinging of Foamboard

Gary:
I don't know. looks tricky to me and you know I don't have much patience. There must be a better way. I like pin hinges, but they will pull out in time. I'm going to try different things till I get it right. Being a crasher, I need something strong. The fibreglass hinges tend to pull away.

The most durable has been the hot glue hinge, but also tricky to get right.

As for the foam seminar, that would be fun if you can find more than 3 interested parties. Count me in.

Well, thar be you, me and the Master - quorum! We sort of do this anyway, it's just another excuse to lend an air of legitimacy to it all.

As for that hinge technique, I really like it. I did a couple of them on scraps to develop the technique, perhaps not exactly as he did it, using a covering iron. I will try on my next Unidentified Foamy Object.

Now that my (store-bought) X-VERT is a complete success, I will get back to some work on my own design, perhaps even starting all over!

Plans, Projects and Building Tips / Hinging of Foamboard

If you don't check in to the Flitetest site from time to time, you are missing some neat stuff. Somewhere in there, I saw the following idea and tried it out on some scrap. It is simple and easy and really works well! I doubt that one would ever break such a hinge, as it has the 2 paper layers sandwiching the minute foam layer at the joint line, yet it is as flexible as a taped or glue film hinge, in my opinion. (Perhaps we should add this into the Flypaper College Of Aero-Nut-ical Knowledge textbook?) Remember, there is more than one way to skin a cat - not that I am into that kind of thing.

I wonder - should we be having the occasional seminar out at the Toyground, during our winter playdays, on some of this Foamology? Of course, it would be  FCAK certified!

Thanks, Dwayne, for your video work and your support. I am putting this project aside for a few days, thinking of the next steps and planning to try out my store-bought X-VERT tailsitter VTOL. Flypaper already has his under control ... sort of.

I have serious doubts about the vertical landing of my Tailsitter, as my brief try to hover at altitude was not very successful. Perhaps I will revert to the vectored motors approach of my Mk.1 plane. And, I have only used 9 of the 10 available mixes in the DX9, so who knows what is yet to be done!

Meanwhile, I found another homebrew design that makes more sense than mine, so I may shamelessly steal some of that fellow's ideas.

Hey that turned out really well,  ;D  Looking forward to see if you get it to land vertically, good job so far.  ;D ;D
