Guillows Spitfire park flyer FINISHED!!!!!!!!!!!!

Some more calculations.....

Using the calculator from this site:

http://adamone.rchomepage.com/design.htm#calculate

I came up with a wing loading of 10.71 oz/sq.ft and a stall speed of 16.2 mph.

I used a lift coefficient of 1 so I am not sure that was correct as I could not decipher the engineering jargon enough to figure that out. 1 was pre-filled into the calculator so I went with that.

I calculated the wing area to be 53.78 sq.in by taking the span x root chord. And used a finished model weight of 4oz.

What does all this mean? I haven't a clue....... Probably too in depth for what I am doing but, I wanted to get a better understanding. Any ideas? I will probably end up tossing the thing in the air and hope for the best

In Germanic tradtion, "Valkyrie" is a fitting name. "Valkarkyries" where the maidens the delivered fallen Nordic warriors to Valhalla (heaen). Wagner's "Ride of the Valkyries" was written and performed to celebrate the deeds of the Valkyries.

Give this a listened and tell me it doesn't remind you of Nazi Germany!

Very Well Then, Sir !!!

I shall take up your gauntlet...and by vow that, by this evening's sunset... the Ambroid shall flow like an orange river !!!!

Let it be known far and wide that I have entered the Frey of heavily loaded, Guillows Scale fighters, and shall Christen my 190 as "Baby Wolf"...germanbeez, please provide a translated and cool title in your native tongue !!

Ok,

So build it quick so I don't have to be the guinea pig!

Seriously though I measured the root chord and came up with 4.15" or 105mm which I understand a little better because I grew up in Canada. Divided that number by three and came up with 1.38" or 35mm. Is this correct? I took the root chord to mean center wing leading edge to trailing edge.

Well, I was gonna reference the Redneck "TLAR" (That Looks About Right) method of CG assignment to put it at about a third of the way back from the leading edge.

Figure I'll jump in the ole Guinea Pig Wheel and run too. I'll get myself straight home today, and shove the gun, engine, airplane, and video camera accessories over to one side and start busting parts from those slabs of petrified Guillows balsa !

Report tonight !

Kim,

I had mine framed out in 2 days, I figured a seasoned builder such as yourself should have a completed RTF wulf by midnight tonight

Funny...makes ME think of low-flying Hueys and Loaches, coming ashore at breakneck speed and laying waste to an enemy camp!

"Kim,

HA !!!! OBVIOUSLY, you have not toured my warehouse of still-born projects. "Seasoning", if it truly exists, can be as big an obstacle to building as having a box of parts and no plans...Just TOO many options !!!!!

However, I figure that the lazer-like attention of my fellow sufferers here will propel me and my Wulf right through to the "Chuck and Hope" phase !!!!!!!!!!!!!!!!!

Why not just use a throttled engine and ROG?

'Cause no throttle device, throttle servo, or landing gear is ALWAYS lighter than a throttle device, throttle servo, and landing gear !!!!!

'Besides, the landing gear would slow me down when I go after them Spits' and Stangs' !!!!

So true but that is where the retracts come in
ONly kidding of course.
I would never attempt retracts on anything smaller than .049 or .020 but that is pushing it.

Well, Wagner was Hitler's favourite composer! Me, I always associate The Ride of the Valkyries with "I love the smell of Napalm in the morning!" ("Apocalypse Now" for anyone who doesn't know the quote)

Wilf

Well i like the smell of nitro in the morning.

Indra:

Then you would have enjoyed being in Vietnam were the smell of napalm and "crispy critters" (toasted VietCong) was in the air quite often.

In truth I prefer the smell of coffee in the morning though both may be addictive.

SuperDave wrote:In truth I prefer the smell of coffee in the morning though both may be addictive.

Coffee is good in the morning but being around my engines and nitro makes me happy so the smell of that makes me happy too.

Here is a pic of the almost completed mini Spit, I still have to "flash coat" it with dull luster coat to seal the paint and decals, I also have to do the cockpit rear windows and the plastic manifolds radiator scoop etc. I's a slow process but I am almost done. I will post a pic of the electronics setup here soon.

Current weight 3.60 oz

Sorry PC issues.........

hey guys! im back! did yah miss me?

Wow man, that looks beautiful! i am really impressed! i just started back up on building last night, you have been busy. now, you gonna post a video of it?

Yeah I will attempt to post a video of the impending crash.

Very nice job there, Cribbs, I hope it flies as well as it looks.

Wilf

AUWWWK !!!!!!!!! The enemy is spooling up! OK...back to "The Butcher Bird" tonight!

Great Spit !!!!!!!!!!!!!!!!!!!!

Kim:

My Spit' to be will be "Restless Warrior" (from "The Lion King")

Ron:

From what I can see in the picture you've done an excellent job. Would like to know the way that you achieved the camo pattern.

On your first flight consider yourself like Wibur Wright in 1903 flying off into the great unknown. If Wilbur did it you can too.

BTW, I'm going to build a dolly to hold my Spit' up off the work surface for adjustments.

Ron I love it!
We need a flight report.

This is the pic I wanted to show. The other one won't let you open it all the way up to see the whole plane

Thanks for all the comments guys!

SuperDave, I handpainted the camo, I figured it was supposed to be abstract, I did use the plans as a rough guide though.

Kim, still have a bit to do so you have time........
