Default us aircore

i don't hear to much about these aircraft here on the spad forum, maybe its because they are commercial kits or something, but i have owned both the trainer and the colt 40. these aircraft are awesome in terms of the quality, in my opinion. the drawback is that you have to build them, but everything is cut already and someone should really take a look at how the engine and radio stuff is mounted! another interesting thing about these aircraft is that the whole thing is 2 mill coro even the fuse, the tail feather are 4 mill and several doublers but thats it. probably the most useful design feature is the wing, when folded correctly these babies have washout at the tip, and man does that help with slow speed characteristics, basically i just wanted to know if anybody is incorporating aircores techniques

When my buddy splatted his Aircore trainer (after about 40 crashes )we disected it and reverse engineered it. I use that wing almost exclusively. We are now working on a workable fuse using 4 mil and less doublers to cut the weight.

I have cloned the US Aircore F-16 and the Colt a few times. The Colt's 2mm wing has been the style of wing I use for most of the SPADs I have built. The 2mm wing with about 2 1/2 inches of dihedral flies very nicely on my Deb. The US Aircore Colt, and the F-16 kits that I own are still in their boxes. I paid about $65 for each kit. For about $2 worth of coro, and maybe $12 in hardware from the hobby shop I can put together the same airplane.

i had a colt 40 wich is in the pic on the left and it would hover at a little over 3/4 throttle, and still take a full power dive, it just would not come apart! no problem with flutter either.

engine was gms47 i dont recall the weight exactly but it was somewhere around 5.5 maybe

The Aircore trainer we had was pretty stout but flew as well as a Deb. It would slow way down for landing and was very docile for a beginner pilot (me). I have wanted to clone the F-16 but have not had access to one to clone. I had some drawings of one but no dimensions.

I was given an Aircore 40 trainer kit with out instructions.
I built it with no dihedral as a tail dragger, and using Spad techniques it came in at 4.5 pounds
( You should see the pile of unused coro parts left in the box, gotta be 2 pounds of them)
With a ringed OS45f 2 stroke, it flies great, floats for ever and can even do a fair flatspin.[8D]
Jeff
ps.
I added 1/2 inch of cord to all the control surfaces.

I have an aircore 40 trainer...and I like it better than my Nexstar RTF. I can throw it in the back of the truck and it will not get punctured like a balsa plane. I also have crashed it a few times, landed in a tree once, and broke the nose wheel several times.

I build spad planes frequently, but it is hard to make one fly as well as the aircore...the spad planes tend to want to stall in a sharp slow turn.

I am almost ready to get a colt....my aircore trainer is starting to loose all the color....probably since I never clean the fuel off........I figure it will just get dirty again.


The plane does weigh in at just about 1 pound heavier than a equal-sized balsa plane...so it will be a little different in flight...stick with a good .46 or .50 engine. I tried a thunder tiget .42 and it flew ok, but took a lot of runway. I dropped in a SK.50 and it is like a whole new plane.....my nexstar has been on the shelf for 6 months without a flight now.

Since you can't get them any more, if you have pictures or especially plans of the F-16, I would be interested in seeing them.

I'm going to build a Colt this winter. Two things I might try with it...
1. Make it a tail-dragger
2. Attach wings with nylon bolts

Have you ever tried either of these things with your Colts?

tesla, i made my colt with taildragger landing gear as it is lighter and to me seems like less maintenance. the airplane handled well but you must be carefull when engineering your tailwheel as mine needed to be beefed up pretty well,

my main gear was just in front of my wing and attached to the fuselage.

Cleatis,

On the Power Cart., do you still install the front wooden block for strength/support, or exclude it completely?

My landing gear mod. for the Trainer 40 will work well to install the main gear to the fuse as you described (I'll probably use 2 3/4 inch wheels up front), but what should I look out for on the tailwheel? Do I still use a 1" wheel, 1/16 wire, and the supplied plywood brace? Yes, it looks like the brace could use a perpendicular wedge above it.

When you order the plane at Tower, they suggest getting a "flexible" pushrod. My only guess is that it's for the throttle servo, so you can install it upside down like the other two (contrary to what the manual shows). If there's enough room on top to use a solid one, why not do it the regular way?

Since it's only my second plane, I was thinking of keeping the wing the normal longer way (the gentler/easier flight the better).

It's strange they never updated the manual with real photos (like they eventually did for the Trainer 40).

I hope you don't mind all the questions. I have yet the find links to a detailed build online.

I'll get some drawings of the F-16 that I have put on here.
I also have Dimensions for a Colt fuse that can be folded from a piece of 4mm coro. Then build the Spadet wing (RNAF style would work, I usually build the whole wing with 2mm, and 4mm ailerons)

I'll see about getting pics and drawings put on here tonight.

F-16 pics. The drawings that I have are in a zip file, found here : http://home.comcast.net/~vance.nelson/f16plans.zip

If you can't download from the link, email me and I'll send you the file.

fantzypantzv@hotmail.com

By the way, for those of you looking for a way to utilize the 'ribbed' style gutter pipe, that is what I am using for the air duct...








P.S. (It isn't 4:50 am here...it's 10:50 pm)

Thanks for all of that. I've never built a AirCore or SPAD from scratch, but these F-16 plans are probably the motivation I've needed.

I have the printed manual. Last night I was working on getting it scanned in to turn it into a PDF. I may have some more time this evening to complete that. I really want to go flying this weekend, so I've been tweaking a couple of planes to get them ready.

Does anyone know why Aircore stopped production on the F-16? I think that will be my next project..... Does anyone have a better copy of the plans? It is a little hard to read some of the measurements. Also, has anyone ever flown one? How is it? I look forward to seeing the manual.

thanks,
Byrdman

Keep tweaking away. Appreciate your sharing. Could you share the wing (span & chord & heights for these plans as well?
