I think it might be spad 4 or 5 before I can do that.  I am now looking in my box of junk for any servos. the standard ones might take a better beating. I will have to see what the weather brings as for Sunday. 

Do not worry - you will be hovering within minutes!

I offer a couple of suggestions:

Set your flaperons to give the wing some reflex - 10 degrees or so.  If you wish, Gord or Brian or  I could offer our assstance.

This is not a plane for fast flying, it is for close up, in your face, 3D work. If you have a 46 on it, get a 11x4 and a 12x4 prop. The 12x4 will probably be best. Set your engine to be a tad on the rich side, so that when you are hovering you will get a consistent fuel delivery. You will be working the throttle constantly, you want proper response and you will need to firewall it occasionally to haul ass vertically when you mess up a little. It's all good fun!

See you on Sunday, I hope.

Plans, Projects, Building and Flying Tips / SPADs over KRCM
« on: October 14, 2011, 12:47:14 PM »
I sense that there is growing enthusiasm in our Club regarding SPADs. It is heart-warming to see a classic SPA3D being launched, plus some other planes coming along.

Rather than continuing the now misleading Topic "Coro-Junkers", perhaps this is a better place to highlight what is under construction, or flying.

To whet your appetite for SPADding, here is a terrific YouTube from this year's SPADFEST:

Here is a fantastic YouTube
SPADFEST 2011 - Part 1


The Fokker D.VII in the video really caught my eye - that aircraft is a superb flyer at any size, well worth considering building. I had a .25-size Coroplast one, it was a wonderful flyer. It was one of the Combay designs popular in the SW Ontario area, particularly at the Cobble Hills Fighter Group.

Lookin' good - the work of a true SPADdite !

Do not worry about the servos - their weight is insignificant, so just use standard ones. Your typical SPAD is going to seem a bit heavy, especially compared to a electric, balsa-based plane, that is just the way it is. Besides, your little "airplane retriever" seems OK with the weight of the new beast.

You are in for a real blast when you launch this creation! Sunday, perhaps?

Here's a couple of videos that should turn your crank. ;D It is as much fun as it looks.

Almost makes me think about going electric :(

Must resist ....


Assimilate, assimilate .... anihilate ... dominate ...


OK, enough of that. Now, when are you guys going to get serious and stake out a time for Combat? Say, Sundays at "high noon"?   It's all very nice to talk about it, and post pretty pictures (not to mention the high tech engineering drawings that Mr. Flypaper offers), but the proof is in the fighting. This is just what we need to perk things up in the Club.

I'd be building a drainpipe or coro fuse for the Twist. If it don't work you havn't lost much.

  Gord.

Yes ... I bet you would!   Hmmmmm ... that is actually a pretty good idea, must ponder ... Thanks!

You mention that you are looking for servos?

Plain old standard servos will work for the SPA3D, and just about any other of the SPAD designs you are likely to find. I really splurged on some of mine, using Futaba 3004 (the ball bearing ones), which the Leading Edge has at low prices. The beauty of most SPADs is that there is enough "flexibility" in their overall make-up that one does not need precision in the servos; in fact, it is my belief that putting high quality, precise, servos into a SPAD would be counter productive, as all of the wiggle associated with the flexible construction probably is counteracted by any looseness in the control system itself.

I eagerly await seeing what you have come up with, and how much you will enjoy it. SPAD on, my man!

Plans, Projects, Building and Flying Tips / SPAD Wing Construction
« on: October 12, 2011, 07:37:56 AM »
In case this is of some help, here is a demo of typical SPAD wing construction. This is the exact design of what I used on Big Bird, my 72" drainpipe-fuselaged machine. I do not know how one could build anything simpler, or quicker, than this!


On this, I had used contact cement to glue the trailing edge and ailerons, but I later on learned about polyurethane glue and use it exclusively for SPAD work, and a lot of other building.

I came across this one the other day. When you dig down, you will find some non-SPAD planes and plans in here as well:

Great work, Mike! Your editting in the music really makes it a good video.

I sent the link to Dave Penchuk, the current head of our IMAA District and organizer of the Giant Scale event, as I am sure he will enjoy it and may post on the Canadian IMAA web site.

Please keep up your efforts. I know that there are other  video clips hanging around on some Members' computer - all that is needed is for someone with ambition to collect a few and do the editting work to perhaps create a nice summary of some of the year's flying at our field. Adding in some still pictures works, as well.

looks like the dura-bat is going to get a lighter wing.  Thanks for posing the pics I now understand some what of how to assemble a coro- wing. Now to figure out the right win profile.   

The wing profile is self-desgning - sort of like SkyNet in miniature!

When you bend the coro over the yardstick or whatever and stick it down at the trailing edge, voila! You have your airfoil. If you are seriously considering building a wing, let me know - I may still have my little sample section kicking around that I made up for Show and Tell at one of our meetings a few years ago.

It would be great to see some more SPAD activity in our club. The local SPAD Pioneers, Gord and Dave Robertson, inspired me (they may wish to not be reminded of that, I suppose). Unfortunately, they got side-tracked by that whole electric fad - although Gord's UFO's (Unidentifiable Foamy Objects) are sort of in the same family, as technically they are made of plastic. Who knows, maybe we will get him back into the fold (little pun there?) one of these days?

Did you score any good political signs in the aftermath of the big election (see, there's another SPAD pun)?

General Discussion / Re: Fail Safe
« on: October 06, 2011, 06:56:47 PM »
To set it up properly you MUST put the IDLE TRIM to the BOTTOM then rebind it. Otherwise it will go to the idle trim position when you shut the trans off, This was the reason for the accidents you mentioned above. I found out this the hard way.


I understand what you are saying, and I agree.However, I should clarify, in my recent cases mentioned these are nitro powered, so there would be no danger of an engine start. However, the throttle was  well above max Idle trim, it was wide open. My first thought was that I had been stupid and bound it with the throttle wide open, but that was definately not the case. I am careful to make a final bind when setting up a new plane, and I check it carefully. Something had changed since that time, about 3 months ago.

General Discussion / Fail Safe
« on: October 06, 2011, 10:52:52 AM »
Once again, I have found that what I thought was OK, was not!

The other day, I noticed that when I happened to turn off my Tx before the Rx on one of my planes that the throttle sat OPEN. This has happened more than once, on different models.

The first couple of times, I assumed that it was my fault for not having properly set it when I initially set up the planes.

The time before this last incident, when I was thoroughly inspecting one of my aircraft just, I discovered that my fail safe was incorrect on  the plane I had been flying all year and which I planned to fly that weekend at the IMAA Meet! Although I know that I had set it up right, once again I had self-doubts.

Now, this last time, I absolutely know that it had been set up properly when I put this newer plane into service this summer. Yet, it was no longer OK. What has happened?

I happened to notice something regarding this in the IMAA Canada forum and I have read of other instances of similar nature in other forums.

It really seems that there is some reason to suspect that the fail safe has a problem, i.e., perhaps some subsequent change you make to the setup such as modifying sub-trims, servo travels and other parameters can mess up the fail safe. I have done all of the above on this model, at the field as I was fine tuning.

Has anyone ever obtained a definitive answer from the manufacturer - in this case I have a Spektrum DX7 and an AR700 Rx in the plane - that would state exactly what the situation is regarding permanency of the fail safe setting?

As I had mentioned to Dave Penchuk at our IMAA Meet, I believe that verifying fail safe settings should be part of the self-policed check list that IMAA requires of the pilots. I think it should be the case for any Fun Fly's, as that is where there is usually a higher risk of airplane to people contact. At least, it would be demonstrating Due Diligence, an important concept should a real problem ever occur.

With the increasing number of Electric aircraft, this seems to me to be moe of a concern. I have had many people tell me that the motor cannot start, or will shut down, if loss of Tx signal occurs. Yet, I have once witnessed a motor start in the clubhouse. I also know a person who got some pretty nasty wounds when his heli started on the bench at home - he says a faulty speed controller was the cause. So, the argument that either the Rx/Rx technology, or that of all speed controllers, insures that this cannot happen does not meet the standard.

As one of those who has lots of ideas, yet often is from the "do as I say, not as I do" camp, I really need to train myself, and encourage others, to pay attention to this potential hazard. "Thou shalt verify fail safe prior to assembling, or staging, thine airplane!". And on a related issue, let's see now, when did I last do a proper range check on my planes ... ?

This ZIP has another haphazard collection of pictures, including construction photos and several Rhinebeck photos that show what inspired me to build such aircraft. There is also an old drawing that a fellow made a couple of decades ago of a Junkers that was used as a base for my development of a model.

This, second, version of my design has not flown - it has sat around for a couple of years as a spare, in case the original wore out. It has been my plan to slap a .45 2-stroke into it, tart it up a bit in some camo colours and let 'er rip. Meanwhile, the original one just keeps on truckin' and is an absolute joy to fly (and a wonder to behold!).

The big advance from the first model is the use of poly glue. No CA or other glues were used. The ability of poly to foam overcomes the issue of making coro-to-coro joints, particularly for bulkheads.

Plans, Projects, Building and Flying Tips / Coro-Junkers ZIPs - RED Original
« on: September 30, 2011, 07:12:20 AM »
Here is the collection of pics, haphazardly organized, of my original red Junkers. One could use these to build their own machine, perhaps learning something about working with coroplast along the way. The next version used a significantly easier gluing technique throughout - no CA, just polyurethane glue accelerated/foamed with window cleaner.

The basic approach can be used in building any coro aircraft. The E1 Eindecker immediately comes to mind. Peter Wagner has a (ugly!) excellent example - it flies well.
