Beechcraft D-18 AKA C-45 Navigator
« on: May 23, 2011, 04:12:01 PM »
Guys:

I have decided to do a Beech D-18 as my next scale subject. That is the tail dragger, twin engined plane that Beech developed in the 1940's. I found a subject at Pensacola NAS on the internet. I even took a trip down there to take my detail photos. Much to my dismay, the Navy had hung the subject about 20' in the air inside of a hangar. I took as many detail shots as I could from the bottom, but I could not access the top of the airplane for photos. I have tried other sources, such as Airborne Media (nice product, but no D-18) and Bob Banka (have to buy his 800 subject catalog first, so I don't know if he includes the D-18). I have good three views by Paul Matt, but I am just having a devil of a time finding enough photos of a single airplane. There are plenty of single pictures on the internet, but I have yet to find any walk-around packages yet. Do any of you have any ideas for sources? Thanks a bunch for your help.

If I remember correctly there was a Navy C-45 walk around available on the RCScaleBuilder site some time back.  I think you have to buy their membership for $20 to access those pictures.  Also, if I remember correctly, the plane that was photographed was at the Pima Air Museum in Tucson.  If you know someone in Tucson, perhaps they could shoot some pics for you.

There is also a beautiful yellow and white D-18 in the Nat'l Air and Space museum.

Good luck with the hunt.

Bob's catalog is downloadable in PDF format.  Looking at it he has 23 or so different C-45 and 20 or so D-18.  If you have the tail number of the one you photographed, he may have the walk around pack for it.   Airelines.net is a good place to start: http://www.airliners.net  If you see one you like and can identify the tail number Bob may have the photo pack.   H^^

Bobs web is http://www.bobsairdoc.com/   The catalog button is on the left side.  If you call him he likes to talk and talk and talk.  So be sure and call on a unlimited long distance line.   LL~

Thanks guys, you have been a great help. The C45J in Pima is on loan from Pensacola NAS, so I was aware of its existence. Its tail number is 213. The tail number of its sister ship in Pensacola that I was able to shoot is 771.

I had been put off a little bit by Bob's $5 fee for the catalog with a $20 minimum order, but I guess I will just bite the bullet. What the H-, I just spent a couple of grand to take a trip just to take pictures of a single airplane (a few casinos on the way helped that cost also). Need to get my priorities straight. Thank you again for your help.

Bob Banka has good stuff and it's worth the money. When building a scale airplane remember that 1/2 of your score is static and poor documentation will always suffer with a low score (not a good idea to confuse the judges). A good set of pictures of an Twin Beech will go a long ways to making a great project. Considering the cost of putting the airplane together with the motor, balsa and other stuff the $20 is a small price to pay to get the right information.

You only really need about 8 to 12 pictures for a sport scale, so look for a photo pack that has about 12-18 pictures.

Good luck,

Good luck!  What size are you planning and what type of twin power.  Electric sure is a easy way to go on a twin.  Guaranteed good run on both sides!  :!  With Clancy's multichannel you could run the engines separately and one of you maneuvers could be one engine out - 3 laps - restart dead engine.  Also with multichannel you could have retracts.

Thanks guys for all of the help. It is great to find people so willing to help. I have already ordered a photo pack from Bob Banka, per your comments.

Fred: you are absolutely correct. The static documentation is so important and yet it is the least costly item in the project. Silly for me to react to such a little cost.

John: I have decided to do this one in a rather small scale (1"=1'). That will still yield a 48" wingspan. I have been building bigger, heavier scale planes for too long. It is time to do something lighter. Coincidentally, I am going to do it with brushless Maxx Products electric motors. The plane will be all electric (motors, retracts, flaps). And, are you clairvoyant? I am using one of Clancy's multi-channel units. I have his systems in my Luscombe Phantom and my Laird Super Solution (both 60"). Wow, that is a wild (and viable) option you have thought of (engine out). However, with multi, retracts, flaps and touch and go, I might have the options covered.I have pretty much decided to go all electric since losing my flying buddy. At least I can fly by myself.

Here is my recommendation on how to run an Electric powered twin.

This drawing shows it being used with one of my Multi channel control systems but will also work with a Universal U/Tronics Control handle.

60"  ain't big - The Eindecker pictured in my thumbnail was an 80" span - till I stuffed it.  However I still have all the pieces.  I plan to resurrect it as an electric fun scale. They have some really big electric motors now.  That will be this winters project for next summers Nats.     LL~

This looks like a setup for running both motors off of one channel with one flight battery.  If you use two flight batteries the black lead of esc #2 will need to tied to the black lead of ESC #1. In fact I have used a standard servo Y harness to connect two ESCs to the controll handle but I did cut one of the read leads.  It goes without saying that if you do use one battery pack the motor supply leads will have to be extended and need to be BIG wire.  At least the same size as the output leads of the battery. Here bigger really is better  LL~

John:

I have that same plane (the 80" Eindecker) about 75% done as an R/C ship. I was going to power it with an OS .90 four cycle. I have modified the body to look like the E-4 (three machine guns).

It is possible to convert that Eindecker to electric I suppose, but it is in the larger outrunner motors (.90 match in this case) and the matching larger voltage lythium polymer batteries where your wallet really begins to empty. This is why I decided to do my D-18 in a smaller, lighter scale. I had been pursuing my Super Solution as a gas powered model for the last ten years. I was also going power it with an OS .90. After last year's NATS, I decided to complete it by converting it to electric. It has finished at just over 12 pounds. I could have done it a lot lighter if I had known that I was going to go to electric. My Luscombe Phantom of the same wingspan is only 5 pounds because I designed it from the start for electric. For that size of an airplane, be prepared to slap some cash on the table.

Jim,
For what it's worth mine is not a kit.  The wing is a recycled Senior Telemaster. The fuse is my own concoction.  It started life as a Big Bird RC fly-in ship.  It was powered with an RCV 120 4C.  As it turns out the RCV is expensive and does not generate great power.  I feel that for scale you don't need top of the line electric.  Hobby King has 160 size motor for $56.
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=14408

4 each 5S 30C 3000 packs =$144  Fly two at a time for 10S  Should have two chargers
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=17829

120 amp 12 cell speed controller $114
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8921

for a total of $314

I paid $380 for the RCV 120 and still had to buy a fuel tank and fuel.  And trust me that sucker could eat some fuel at $12 a gallon (club fuel). PS dumped the RCV on eBay. LL~

John:

Wow! I need to find some better sources. My standard is Maxx Products. Their 120 sized motor with an appropriate controller is $360 !! Worse yet, Tower Hobbies 5S 3000 lipo's are about $130 EACH !! (working strictly from memory here). You bought yours for $36 each?

I need to get better at this. I have about $600 for the same items in my Super Solution, and it is only a .60 size.

Apologies for referring to your Eindecker as a kit. I should have known better. We scale guys have more of a tendency to wing it (pun intended).
