I started building Bruce Tharp's Super Flying King twin-engined version. The kit quality is unbelievable. The ribs fit the spars perfectly without any adjustment to the notches. The parts stay where you place them. I have finished basic wing framing and am working on sheeting.
I am leaning toward using two G-38s for power. I usually cover with Monokote, but am considering Stits or Solartex. I am going to use Robart's Fowler hinges on the flaps. I have shot about 170 construction pics up to this point and 20 pages of construction notes. I am going to put it all on a CD when I have finished.

I am just about to begin building my super king. I sure would like a copy of the cd you are making of the construction. Will it be available? Thanks..

My intention was to give the CD to Bruce Tharp as thanks for creating a twin-engined version of the Super Flying King. I will make it available to anyone interested. Of course the question is when. I am the world's slowest builder and it will come after the SFK is complete. It takes time to organize lots of pictures and combine them with text. I have made arrangements with our club's webmaster to use space on our site to publish pictures of the project as I build. Our club website is www.baxterfield.com, but as yet have not had the time to provide any pictures of this project. I will post a thread here when they are available. Thanks for your interest.

I have contacted Bruce Tharp about maybe turning this twin-engined Super Flying King into a tri-motor. He didn't try to talk me out of it. My plan is to use three G26s instead of two G38s. This will transfer some of the vibration from the wing to the nose of the fuselage. I will have a total of about 7.2 hp to haul a 35 to 45 pound airplane. The addition of the Robart fowler flap hinges is going to require some ingenuity to modify the current flap and wing TE, but should be worth it to make the plane a little more unique. I think some Tiano resin molded dummy radial in front to the engine with some custom 1930s style ring cowls would look interesting. Not quite a Ford Tri-motor, but similar. I will post some pictures of the flap setup and engine mods when they occur. Buy a Bruce Tharp kit. You will never be sorry you did!

I just ordered mine today! Talked with Bruce on the phone, (really nice guy) he answered my questions honestly and to the point.
I too would be interested in your tips. complete or incomplete. I'm adding a few additional bits (British for parts not included in original design) to mine and am looking forward to getting started. I'll be sure to share my experiences with anyone here.

I got an email from Bruce last night. He gave me your email address. I will be contacting you later about exchanging information. So far I have shot 130 photos of just the wing alone. I am on page 30 of my notes. My engineering background forces me to over document everything. Mitoor in Yuba City was interested in my installation of the wing joiners, but I had to beg off as it would have been necessary to stop building and type up 11 pages of notes with diagrams.
I had never heard the term "additional bits". Monty Python taught me the term "naughty bits", but that is "something completely different". Are you British? My favorite Brit is R.J. Mitchell, of Spitfire design fame, and not because the "R" stands for Reginald.
I hope R/Cers give Bruce Tharp a try. He is the nicest person of I have ever talked to or corresponded with in this hobby. His SFK kit is of unbelievable quality in parts and fit. He is taking the time to supply me with a wing kit for the 215cc radial test plane that I want to build. In addition to the parts, he is giving me valuable design tips. He used to work for Sig and designed the Four Star 120 and others.
I have backed off the tri-motor idea. I want to put a video camera in the nose. It is the one I bought from Super Circuits 4 years ago. I was waiting for the right platform to use and I think the SFK may be it. I am committed to installing fowler flaps since I now own $200 worth of Robart Fowler hinges (8 at $25 each!).
I just finished the tail feathers. I decided to entirely sheet the tail. I added lightening holes to the elevators and saved an ounce. Bruce says it won't matter much as the Twin will be tail heavy anyway. A pair of G38s are on order. For a change of pace I am going to finish the fuselage before working on finishing the center wing section. Included a pic of stab just to show everyone that I am working on it.

The prototype plane on Bruce Tharp's website, www.btemodels.com, uses a 3W75i. I would think a 4.2 would work just fine. I know you won't be disappointed in the kit. Finished the tail feathers this evening. I am getting 35 degrees of deflection on the rudder. I wonder if it would be a good idea to double bevel to get as much deflection as possible, in case of a single engine failure, to counteract the yaw. If you want to read an interesting article on twins, go to "www.rcwarbirds.com" and click on Twinman (Mr. Lumpkin). Couple of more pics. By the way, lightening holes in the rudder may have been a waste of time. I saved 1/10 th of an ounce.

Status: offline 		The rudder line kind of reminds me of the "Maule" airplanes. I just e-mailed bruce and asked him about engines/exhaust systems. What kind of servos are you gonna use, and are you going with a gyro in case of engine failure? I think I like this plane so much because no one around here has one.

Status: offline 		Reg,
Yes I can understand the documentation process. I have quite a few years of building under my belt so I don't anticipate any problems. "Additional bits" : Anything not normally found in your everyday RC Aircraft. On-board starting, Nav, Strobe and landing lights, 2 onboard cameras(one full Camcorder & OSD video downlink), 2 RS-232 DataRadios, GPS, 2axis gyro, temp and rpm sensors. Did I forget anything? OOh and by the way, I'm not British, I have met a few Brit girls, nudge nudge , know what I mean? know what I mean? My favorite American is Chuck Yeager he's got some bragging rights very few could top. My favorite brit is "AngryKid" visit http://www.angrykid.com
Why all the bits? I once was told if you love something, set it free. If it loves you back, it will return. I want to test that theory.
Reg, I'm worried about you.... 215cc ? ? ? My god man, your not thinking of getting in it are you?
I opted for the Twin add-on to his kit also, but plan on using the engine pods as electronics bay's
Power? Fuji Bt-86, WITH, ( gotta love this part) Onboard starter. I refuse to put my hands anywhere near that prop. They are expensive. Thinking of going with 2 g-38's also but worried about vibration in the cameras. I'm very interested in a link or kick in the right direction for the "Robart Fowler hinges" you are using. They will make a great addition to the kit. In both appearance and functionality. I considered the stall tips, and haven't completely ruled them out.
My construction details will be posted on a website, I'll drop in the url when it's up and running.


Michael

At the moment I have my nose pressed against the window looking for the UPS man.
He drives a Big Brown Truck. . . . Have you seen him?

Status: offline 		Don't worry Mike. The 215cc radial I bought is intended for my Hostetler 40% Gee Bee Model Z. The wing kit Bruce is going to provide to me is for another 215cc engined airplane (see threads on "please help me find this plane" for pics). After perusing your list, your twin is going to blow mine away in number of "additional bits". By the way, Bruce mentioned you were going to add a picopilot (whazat?). He also said you were going to use the plane to scout tile here in the Midwest. Again I am at a loss. Please let me know what that is. I may want to "scout tile here in the Southwest". As for the other goodies, I am a retired electrical engineer, who used to design hardware and write software for embedded microprocessor based systems. I would love to collaborate on all the telemetry bits.

Reg Mason

PS: I bought the STOL tips. The Germans make some nice on-board starters for Fuji engines, but seem to be rather heavy. But a plane that is going to weigh 35 - 45 pounds, who's counting.

Twinman's article on twin-engined planes on the RC Warbirds website makes a good case for using gyros to save your plane in case an engine fails. Michael listed a 2-axis gyro in his list of "additional bits". Maybe we should caucus about this.
