Default BLT Park Flyer plans

Hi All, does anyone know of some plans for the BLT Park Flyer (or anything similar)?

The plans on Aerofred seem to be incomplete.

Thanks!

P.

Looks to me to be nothing more than a modified (nicer concept) than a GWS Slow Stick....!

Take a look at these links for ideas and options...:

The Slow Stick has been around for ages......you'll find hundreds of variations by just Googling Slow Stick.

Hi Pizzano, yes it pretty much is a Stick.

Thanks for the links.

I guess I was mainly in search of plans for the balsa wing more than anything the rest can be ad-lib.

Wing looks pretty simple. No ailerons, constant chord, center sheeting, flat bottom airfoil.
If you know the span and chord, and what size spars you want to use, I could draw you up some rib patterns and a build plan in CAD, and send them to you as a PDF file.

What goes up, must come down. The trick is to keep it in one piece.

That would be cool , well I guess the idea is to stay as true to the original as possible. Im not sure on the chord, it mentions it is a modified Clark-Y. A DXF might be handy. then I can 3D print a template for the ribs.

The listing on GP's site has the following info.

SPECIFICATIONS
Stock Number: GPMA0001
Wingspan: 42 in (1067 mm)
Wing Area: 294 inē (19 dmē)
Length: 28.5 in (724 mm)
Airframe Weight: 2.4 oz (68 g)
Ready-To-Fly Weight: 9-13 oz (255-368.5 g)
Wing Loading: 4.41-6.37 oz/ftē (13.5-19.4 g/dmē)

There is also a drawing in the manual on the Hobbico website if that gives any clues.

With the span and wing area, it works out to a 7" chord. Simple rib - use 1/4" square stock for the main spars (I would add some shear webbing, just to be safe) and leading edge. Trailing edge is 1/8" X 3/4" balsa. Main ribs on the outside, sheeted ribs for the inners, where the wing attaches to the fuse, and sheet with 1/16" balsa.
If you need a wing build plan, tell me the number of ribs you want to use, and the thickness of the balsa used for the ribs, and I can do one up for you.

I can't attach a DXF file to a post, so PM me with your email and I'll attach them that way.

Thanks a bunch! good point on the sheer webbing. Looks like the instructions call for 1/16th (1.6mm) balsa for the ribs. There are 7 inner ribs and 1 outer at each end of the wing half. A wing plan would be super.

Any idea on the distance between the center wing rib W1A and the one next to it? Those would be the sheeted ribs I drew up. Once I know that, I can make up a PDF wing plan you can have printed using 1/16" balsa ribs at equal spacings.

My best guess would be approx 76.2mm as that is the prescribed width of the sheeting over WA1 and the first rib.

I think they meant to use 3" wide balsa for sheeting. This should work for you. PDF, full size. You can print as tiled or go to somewhere that can print large prints (UPS Store, Staples, etc) for a couple of bucks.

You're welcome. Always willing to help out a builder if I can.

Converted the DXF files to STL and printed those out. Balsa stock inbound.

Wow, that is great work! I would love to have my own laser cutter, but I just can't justify the cost.

Yeah a laser cutter would be neat! Decent 3D Printers are quiet affordable now though.

Here is a peak of another little experiment I have planned. I might do a quick build log on it when its underway. Will be using 3mm Depron sheet for the wing running a 3mm carbon tube down the middle.
