Scale?

mccarthy1028 · Post by **mccarthy1028** » Tue Mar 27, 2007 3:30 pm

I wanted to know what the Scale would be for
B-29 Wingspan and Length in 1:18 Scale
B-17 Wingspan and Length in 1:18 Scale
B-24 Wingspan and Length in 1:18 Scale
B-25 Wingspan and Length in 1:18 Scale
And Possibly a Lancaster Wingspan and Length
Also how do you figure out the scale, divide the 1:1 numbers by 18?
This would be very helpful...Thanks

Just divide the real numbers by 18.

Thats what I figured, i was just making sure...I keep seeing all these plans for RC planes, and they have large wingspans but I wanted to see how similar close they are to 1:18 scale...Not sure if anyone has attempted to build one from scratch...

The RC stuff tend to have larger wings in perportion to the fusaluge, because of the limits of engine power generally available. It's good to check and see if it's close enough.

Good point. If you want an accurate set of plans, make sure the plans are "true" scale. I thought I had come across a good set of dc3 plans (included rib formers, fuselage cross sections) but found that the tail fin was over sized and the engines where set further out and set at a pronounced angle when compared to smaller "true" scale drawings. They basically changed the blueprints to allow for more easier RC flight characteristics.

Dang, a 1/18 B-17 would have a wingspan over 5 feet long, and a length of over 4 feet!!!, but imagine this, the C-5 galaxy would have a wingspan of over 12 feet long!!!!, and a length of over 13 feet !!!!!! dang, but another more amazing thing would be the Spruce Goose, wing span in 1/18, get ready......Over 17 FEET LONG!!!!!!!!!!, and a length of over 12 feet, but a height of over 4 feet tall!!! DANG THAT would be huge

while r/c planes are not ideal and do often have wingspans a little out of proportion with their length, they also represent the best chance of getting large airplanes, like four engine bombers, in close to 1/18 scale and they are also good for more obscure aircraft, such as the beaufighter, which is unlikely ever to see mass production.

The EAM B-17 is perfectly proportioned and scales out to 1/17.9 in both length and wingspan. Half the work is even done for you as the fuselage and engine cowls are pre molded.

Thats sort of the project that im thinking of attempting, the EAM B-17...But I built a 1:48 B-29 as a kid and thought it would be awsome to have a 1:18 B-29...That Spruce Goose is HUGE...Thanks for the help guys...

it would be awesome to have a 1/18 B-29, you're right. But at 66 inches by 8 feet it would be quite a beast. If you're not too fussy on scale EAM also has a B-29, but it's 1/15 scale. Almost a 10 foot wingspan.

Oh the thought of haveing a 1:18 B-29 is realy cool.....only if........

Ok I am awake now

MIGMADMAVIS · Post by **MIGMADMAVIS** » Tue Mar 27, 2007 7:52 pm

Yes, with a 7 1/2 foot , something like that wingspan, I would have nowhere to hang that, or how the heck would the roof support that beast!!!!!,

that's another advantage of r/c aircraft. For their size they are very light...

Did someone say 1:18 B-17!

THE HOLY GRAIL of 1:18 aircraft.

Post by **aferguson** » Wed Mar 28, 2007 9:24 am

the B-52 is the holy grail of 1/18 aircraft..

Nice!!

Although I think its a bit small for 1/18.
Is it r/c?

Post by **aferguson** » Wed Mar 28, 2007 10:11 am

that's the built up EAM r/c B-17. It's 1/17.9 scale.

pickelhaube · Post by **pickelhaube** » Thu Mar 29, 2007 4:11 am

The holy grail of 1/18 would be either the B-17 , B-24 or B-29. The B-52 is big and all but it does not have any pazzaz.

Define 'pizzaz'...

I define pizzaz as: spectacular size, revolutionary design, rich combat history, 50 year+ service record...

Is that plane a scratch custom built, R/C, or a model? How much does it go for if it was of the latter? It is very nicely done.

Moth · Post by **Moth** » Thu Mar 29, 2007 8:01 am

I dont know about Pizzaz, but the B-52 is very ugly in my eyes, it is a just a stick with wings.
The Tu-95, now that's a beauty!

Post by **aferguson** » Thu Mar 29, 2007 9:21 am

a tube with wings..

The B-17 is the EAM r/c kit in built up form.

Enough fighting gentlemen, they are all great planes...But only if they make them in 1:18...Last I heard the EAM B-17 Kit was going for about $350 bucks...and the B-29 is no longer available on their site...I saw some B-52 plans on EBay for about $15.00 bucks...Has anyone seen that 8 jet engine RC B-52. I think the darn thing was worth about $100,000. I saw it on You-Tube, it was a sad site seeing that monster crash and burn...I just hope they come out with some of these larger size bombers afters the B-25, I wouldn't mind dishing out a couple Benjamin's for one...

You can get all the necessary EAM parts for the Fortress for around $275 i think. The B-29 was way over scale anyway.

The B-52 that crashed is being re-built and will supposedly be even better the next time around.

There is an approx. 1/27 scale r/c B-52 ARF coming out soon for under $800. It is about 6 feet by 7 feet.

I think 21c is going to find they have engineering problems with the B-25. Wing sag, u/c sag and gross weight being chief among them. Without using a metal wing spar i can't see how they'll make it so the wings wont sag over time. Same goes for the u/c.

A 4 engine bomber, that's not built light, like an r/c, will be very, very heavy and perhaps too heavy to be feasible, unfortunately.

I need to catch up.

Pazazz.

The 52 just droped alot of bombs on Veitnam and some on those big sand pits in the middle east. The WW2 bomber are vintage heart warming ( ? ) planes. They represent bygone days that are almost just a memory. I guess I had to much corn for dinner.
