RE: Old Spad Builders

sttb is pretty much the timeline.
I guess it depends on how you define original group, there used to be one of sorts, but i've not seen it in years. Its a long drawn out story, spread over 4...

RE: Old Spad Builders

they don't build or fly much anymore. I still keep in touch with them on a fairly regular basis. Tattoo's retired, and playing in a band.
Incidentally, they aren't old spadders, they're the...

RE: Definition of a SPAD

basicly, one thing that spads have in common is a coroplast wing and tail feathers. The rest is pretty much open in my opinion. Thats the one thing that all spads- the ones on STTB at least (save...

RE: qhor vibration airation in tank

i think i searched for dubro products, then looked in the fuel accessories category for it. They do a nice job of hiding it.

RE: qhor vibration airation in tank

if you haven't already, try balancing the prop. Sometimes that will cure it. If not, you can get a sintered bronze clunk to replace the clunk in the fuel tank that will break up the bubbles before...

RE: 2008 SPADFEST Website

I don't want anyone to think i'm picking on Joe (Emailbanter). I am certainly not. Him and i have had our differences, and thats fine. But, let me remind you guys of a few things.

Somehow, i don't see asking for clarification of the rules for the event as either cutting throats, or hitting below the belt, or smashing heads. 2 club member had given 2 very different idea of...

So, what i want to know is who's right - i see 2 differing opinions, and both are purportedly both club members. Who is the CD at this event? If there are rules specific to this flying site, they...

RE: SPAD Swept Wing Canard

you need more fuse area for better knife edge- or a bigger engine to go faster, or more rudder. Keeping the area of the rudder and the fuse the same above and below the vertical cg of the plane...

RE: Wild Thang?

use a mac calculator - like this one - http://www.palosrc.com/instructors/mac.htm

enter all your dimensions. For the far forward of your cg, use 11% mac, and for the rearward most, use 18%...

RE: Wing question

To make a nice airfoil, the flutes need to run chordwise. And, you simply can't get coro wider than 48". Thats why they're all in 2 pieces.

RE: Fastest .40 sized spad

the 1056 is the exact same formula as you use, its just simplified - all your doing is converting from inches per minute, to miles per hour. To start, to get the inches per minute, you multiply...

RE: Fastest .40 sized spad

130 mph sounds really high for a 48" wing plane. my 40" dino 2's running similar prop and engine with a screen door spar weren't running much over 100 mph. I suspect that the real issue is your...

RE: Fastest .40 sized spad

who knows, you might've gotten more with a 10x7 or 10x8 apc. Mine really unloaded in the air, i was spinning well over 23 grand with a 21 buggy engine, and a 7x6. That was on the smaller size,...

RE: Building a SPAD Trainer

first.... If your going to enlarge the wing, you need to enlarge the tail, and fuse length proportionally. Second, on the fuse - pick one. You don't need both the angle and the corofuse, its...

RE: Another shot at improving spars

arrow shafts are ok - but, really, they're overkill. I use c/f tubes - normally 5/32" od. Most kite shops have them. Here's where i get mine - http://www.cstsales.com/Hollow_Carbon_Rods.html

RE: Another shot at improving spars

they're not cheap, and really, on a 40 size plane, the yardstick is tough to beat - light, and cheap. However, if your building a 3" thick wing, foam and c/f makes a much lighter spar than you...

RE: Another shot at improving spars

it'll be really strong when you glue it to the coro - that'll mean it'll be mostly loaded in tension and compression - which c/f tube is extremely strong in.
I've done something very similar -...
