"Things I Want To See Frank Make" ! ! !

[Ez2cDave]

Hi, Frank !

I took your suggestion and started a new thread.

So, to get things started . . . How about a "Starship Of David", from the Mel Brooks movie "The End Of The World - Part 1" ?

If you accept my "challenge", I will send your the data you would need to design this model ( sufficient to make accurate "patterns" ) . . . Send me an email !

Here is my email address : [email protected]

That would be perfect for a saucer, maybe with a clear center or with two outboard angled motors to make it spin......Who is the saucer master here?

 

[Crawf56]

Klingon "Bird of Prey". Wings not angled down.

Bachem Ba 349 "Natter": https://en.wikipedia.org/wiki/Bachem_Ba_349

This was a WW2 German rocket powered aircraft. Launched vertical, designed to fire rockets at bombers.

Not used in combat, but 20+ successful test flights.

Yokosuka MXY-7 "Ohka" : https://en.wikipedia.org/wiki/Yokosuka_MXY-7_Ohka

Japanese WW2 suicide rocket aircraft. Used in combat, semi successful.

I actually have plans for a version of this aircraft from the Powered Slope Soaring Association in the UK. About a 40" wingspan, powered by four D engines.

Yokosuka MXY-7 "Ohka" : https://en.wikipedia.org/wiki/Yokos

John boren build a big RC Betty bomber with an okha he could drop but I don't know if he ever finished it, the wing is really far forward and very small...

OK . . . How about a Romulan "Bird of Prey", even just as a "gliding portion" ?

North American X-10

Northrop X-4

Yokosuka MXY-7 "Ohka"

That is one ugly Bird. Beauty is in the eye of the beholder.

 

[burkefj]

This is fun, keep going I did just finish this though....

 

[burkefj]

I have done a Komet before a few times, CG is hard because the nose moment

I would love to see that fly......maybe once.

Hi, Chuck !

I am envisioning a jettison-able, forward tube assembly ( for Boost Stability ), which would leave the "Bird Of Prey" to be piloted to the ground, via RC !

The up part of the flight will be fun.

Chuck,

Actually, the Simplest method might be to boost it as a "Parasite Glider" . . .

[John Kemker]

I vote for the Heinkel P.1079 "Zerstorer"


and the North American X-10

Can you make this?
Pterodactyl - the original bird of prey.

 

[Ez2cDave]

Hmm . . . SUKHOI-27 ! ! !

[burkefj]

the bird of prey is going to be tough for any disc shaped or semi oval shaped the CG is going to be at about the 25% point of the cord which is pretty far forward, so any rear-mounted engine is going to make it extremely tail heavy, even if just as a glider you're going to have problems with yaw stability, you got those forward swept fairly large warp engines almost ahead of the leading edge at the front, and the spine fin is pretty small..

 

[neil_w]

Hypersonic plane concepts are extra-cool, but rarely feature anything resembling a cylindrical airframe. Nonetheless... maybe?

I've loved this one since I first saw it:


Someone needs to build this one as a rocket:


Aw heck any of these.

 

[burkefj]

Keep em coming, don't feel bad if I don't decide to build yours or any of them for that matter, I need to be really grabbed by a design, plus I don't feel like doing built up fuselages, so swoopy fronts, I can't do justice to, like I did my Mig 25 it looks good but an SU-27 would look stupid because the swoopy nose is so fundamental to the design. For the low boom SST, I just HATE that shape, too many damn pointing things jutting off of it, plus I seem to be stuck in the 60's.....A boeing 2707 I might get behind, with fixed wing sweep, I always like that, but this is a fun thread....

Dave F. I did do one back in the day as a mid-rear mounted pusher electric, it had some odd tendencies, needed up trim or washout to be stable, and the elevons angled back aren't very pitch effective, especially when nose heavy as in a rocket glider after burnout, which is why most models of it, like the plans you show and the upcoming Northcoast kit don't go with a scale wing sweep, here is the bottom of my plane done in a special retirement scheme for the air force as you show in flight.... It also has a pretty high front/lateral area which requires larger vertical stabs sometimes relative to cg...[/QUOTE]

Frank,

How about an internal, sliding Ballast Weight, deployed at Apogee, to alter the Boost CG to the Glide CG ?

There is also the F117N / F117X SEAHAWK version . . .

Ooooh! That looks great. And the benefit of doing a modern Boeing project is that it doesn’t have to work, you just need to spend lots of money.

From what I have read, the real F117 wasn’t the easiest bird to fly either!
