Agreed, Jim. But the charts show 9" 2 blade props doing OK, just not quite as good as the 10."

As to static thrust, I think it's most important for slow, draggy airplanes, like WW I types. THen that factor carries the most weight in a power decision. I'll be using a GWS 300 with 'D" gears for my Halberstadt build; swinging a 12" prop it efficiently makes quite large static thrust numbers.

With the Stuka, the 350 impressed me since I was looking for not only good static thrust, but also efficient use of power. The figures showing 11 oz. thrust also say it'll only draw 5.7A, well within the capabilities of the Pixie 7P ESC. Also, if a motor is capable of good static thrust, by 'upshifting' to higher pitch they've got the 'oomph' to keep up. I just had a good feeling with the 'D' gearing figures. We shall see.

Remember, the Stuka is by no means a speed demon. It was meant to be a stable bomb platform, and was pretty slow anyway, not a dogfighter.

If mine flys halfway decently I will be a very happy camper!

I have bought a comet Stuka on Ebay....to replace the dead one!

Hey, Paul-

Yours was one of several Stuka builds I looked at when deciding how to do mine. If you remember, Jimmyray also built a successful one that used only the scale ailerons. I was going to do something similar to yours, except with thin carbon rods actuating the auxiliary ailerons, but after reading the posts I dropped the idea. I'm using vertical stubs of toothpicks to mount my nonfunctioning flaps and vertical Robart 1/2A Hinge Points for the ailerons. So far so good.

That Comet Stuka is of course a 'D' model, so it's like doing a whole different plane! I have one myself, though after the Guillow's kit I'm about Stuka'd-out for a while! Some serious reengineering will be required to keep me happy, like the Guillow's wing, the ribs sit atop the TE, which can easily lead to covering sagging

Since I've already posted it before, it's nothing new here; here's my own aileron/flap installation (see pic)

Ran across these photos on the net. Apparently according to a book I have the Germans were planning an aircraft carrier. This was to be the naval version of the Stuka. Pretty cool.

Yep, Mike, that's the Ju-87C. My primary color reference book from the Histoire & Collections series has a write up on it.

Only 10 were built, intended to be used from the Graf Zeppelin aircraft carrier that was never completed. Besides the folding wings, it also had clipped wingtips, an arrestor hook, attach points to carry a torpedo, and even a reinforced landing gear that could be jettisoned via explosive bolts in case of ditching.

Could be a neat scale subject on its own...even though the carrier was never launched, the dive bomber squadron intended for it had a neat squadron logo with an anchor on it to indicate its nautical aspect.

Glenn,

Are you going to have room to fit your Li-Polys in that little area underneath the canopy?? I will be using Ni-Mihs but may have to use a stick configuration on the battery pack to make it fit. It's going to be tight either way.

Oh, sure, no problem...the 1200 mAh 2S pack is 2.5" X 1 3/8" X 1/2" and easily fits. I use Velcro strips so there are lots of options for getting it in (I'm installing the servos and such first and will work around that...I'm making this up as I go...lol) in general, then I can fine tune it be repositioning the pack.

Good guess, Paul, but nope. It's an ingenious screen name; had to think about it for weeks...LOL

Nah, it's what I do. I fly freight in MU-2s.

Oh, my, now that's funny!

I left this window open a few hours ago, just got around to responding without refreshing it

What are the odds of picking the same pic out of 154 on airliners.net???

See, great minds think alike...

the carrier was launched. the graf Zeppelin was partially destroyed by the germans at the end of the war. afterwords the russian used it al little while as transport ship. and used it as target for dive bombing units.
work commenced on laying down her sister ship and plans were ready to convert the ocean liners Europe, Gneisenau and Potsdam to auxiliary aircraft carriers. Graf zeppelin and her sister were to carry 30 Stukas and 12 naval 109's Europe 18 Stukas and Gneisenau and Potsdam each 8 Stukas. Later (in '39) Seydlitz would also be completed as a carrier carrieing 8 Stukas and 10 109's.
the C version of the stuka had rubber flotation bags in his fuse. these were disigned to keep a ditshed Stuka afloat for at least 3 days on a calm sea.when the ship was destroyed the some of the C's that were to operate from it were used in normal squadrons. they were used in the polish campaign and later.

Ya that is funny... It was the only respectable picture they had of an MU-2.

BTW: Does anyone out there know if there are any original WWII Ju-87 Stukas still flying today. I've never seen one even on TV so I would have to assume not. Too bad. I guess thinking about it, there aren't even but a few original German warbirds still flying these days at all.
