Yeah, here's a quick Paint drawing:

I've been over it a few times, and was only wondering how well it would scale up (this idea is for a smaller model). I thought that using thin brass sheeting to line the groove might be good (i.e. a triangle shaped piece, top and bottom). Also, you can have more than one.

Mike;

I think Big Ben is talking about the method used for full span ailerons where you have a vertical component with an aileron connector at the end and the bent part runs parallel to the aileron hinge line. Like most trainers use.

Attached are a few pictures of my ship not glued together yet but getting close. It is BIG!!

Hi Guys,

Great thread. Check this web site out. This will hid all the linkage. www.irfmachineworks.com/rds/ I'm working on a Palmer 1/12 scale B-24 right now (tons of mistakes in the plans).

Your Herc looks GREAT!!!!


Bomberguy,
That's exactly the type of solution I am looking for. Thanks for the link.

Hello all. I am curious of this kit and am looking for some answers. How is the kit in the sense that "it is truly a follow the instructions and you will be fine". Are there any problems with the kit besides the lack of some balsa pieces? I am a crew chief on the C-130 and notice oltimers wing is tapered from root to tip on top. The full scale plane has a flat top wing from tip to tip and it tapers towards the tips on the bottom starting outboard sides of no. 1 and 4 engines. Is that the way the kit is built?
The planes look very good and I hope they are succesful in flying.

octanehuffer,
Don't think by any means this is an easy kit. I don't want to scare you off, but you must be ready for some building challenges. The directions are not very clear and require much interpretation. With that said, it can be built!! Oltimer is much further ahead in his build than the reast of us. I am slowly progressing as my wing panels come together.

The wing is straight throughout the center section, which comprises the fuselage to the inboard engines. The wing then tapers out to the wing tips. The bottom of the wing is not flat. My ribs are rounded to a more symetrical shape. The flaps can be made very scale using the technique Oltimer and myself are using. It will add a very nice scale fowler effect.

If you still want to proceed, be sure you are ready for a build that will require alot of thinking. The plans are nice as a guide, but when paired with the kit from Precision Cut, it can go from simple to impossible quick. My advice, if you are up for the challenge, alwyas plan 3 steps ahead. Always look at how the current build area will impact the next. Many prolems are not recognized until you move into the next build section. Take many measurements between each plan sheet. This may head-off any problems. Also, read this entire thread. Granted no one has completed the plane yet, but it's one good guide to limit building issues.

I wish you luck when you start this build. I am always available to answer any questions.
Mike

PS- The sick part about this build, I want to build another: MC-130.

Adam;

Your perspective must be wrong on my wing. It is flat as a board on top and tapers just like the full size!

Thank you guys for the replies. Before I get ahead of myself and start a scale prject as this one I wanted to make sure that the kits was truly scale. I meant no harm oltimer just needed to know. Your model looks very very good. I am good at playing chess and can think steps ahead but when it comes to building-we will see. I have build alot of kits but never to this stature. I commend you guys! I am looking for a scale plane that will be "the one" for me. I keep eyeing this bird, looking at others, but find myself coming back to the C-130. I was talking to a scale flier last night and I told him I was kind of intimidated by 4 engines. His reply was "4 are better than 2. If I had an engine out with my P-38 the only way to save the plane would be if was already on the ground." Reassuring.

hey guys i building the c130 from just a set of plans from 1954. scaled up to what i wanted.. will have pics soon ..using built up carbon fiber for spars and 1/4 luan for ribs and lots of blue foam..

Octanehuffer;

This aircraft can be VERY DEMANDING to build and in my opinion a very worth while project. Like anything else in this world it has its share of problems. Many parts do not fit as advertised and others are just missing in the kit. Mike is quite right when he says it a challenge. If you have a lot of time and don't hurry the construction you can have a beautiful model of a great aircraft. If you are a good chess player then your skills will be put to the test on this project. This thread is full of information from contributors to guide a builder through the "rough" spots. Much can be gained from the experiences of the group who follow and contribute to its succes. Best of luck on your project!!

Thank you very much Frank. I will give the project a green light and look forward to 5 year long up hill battle. Is there a better kit than the short versoin. I want it to be as complete as possible.
Adam

oltimer

Octanehuffer;

I would sincerely recommend the SHORT KIT. I had to replace almost all of the sheeting material I got when I bought the FULL KIT. The wood was heavy and stiff as a board. I am using 4-6 lb. wood for my planking to save weight. I believe Mike and others ordered the short kit which in retrospect is the better option.

Octane- JUST GO FOR IT!!! Take the challenge.


Tonight I finally got my wing panels to a new level. They now mate with the center section. I still need to put my right wing back into the wing-jig and set the washout and install the webshear. Here are a couple pictures showing how large with project is growing to be. I used my helper to show the overall size.

Looks good uker.
Short kit it is and then buy stock in a balsa company.

Frank,

I have gone have several pages looking for your outboard flap installation. Did you ever post pictures of this? I'm curious how you mounted the inboard carbon tube (for the outboard flap) where the outboard panel meets the center wing section. Also, where did you end up placing the O/B flap servo?

I finally got to a point where I can start moving ahead (more quickly). I got my wing panel framed with all the web sheer installed. I am very happy with the results. Its easy to see the washout I built in. I hope this "wing twist" doesn't impact the ailerons too much. I'm currently building my ailerons and my flap will follow shortly.

How did you opt to actuate your extending wing landing lights, a servo or air cylinder? Currently I'm leaning toward a servo for ease of maintaining my air system. I hate chasing leaks.

Mike

Mike;

The outboard flaps are a bit tricky because the wing chord varies and so the alignment doesn't seem to come out perfectly. Either its correct when the flaps are retracted or its the correct angle when extended. I chose the latter. The problem is that the outboard tube is at a much narrower chord and therefore one cannot easily achieve the same "tilt" angle for the tubes. This is what causes the issue. This is what I ended up with after about three tries. The flaps work good but must be "perfectly" parallel to one another or they will bind. I used the top of the wing tube as reference at the inboard end of the wing where it meets the center section hoping that the flaps would align. This accomplished I adusted the outboard tube to suit. Because the flap is so long compared to the inboard flaps it binds easily is alignment is not perfectly parallel. I chose the position for the servo as close to the center of the flap as I could but the outboard engine is in the way so I chose the bay inboard to put the mechanism. This creates an "off-balance" condition when actuating the flap but if the slides are "free" and parallel it works O.K. When checking the motion of the flap be sure to use the "push-point" of the servo to see if there is any binding motion. This is the biggest problem as the flap is so long. I only have a couple of pictures of the mechanism and they are attached.

Regarding the landing light I am using an air cylinder and have enclosed a couple of pictures. A servo could easily be used. I chose not to use the reflectors provided by Dan but rather bought a couple of flashlights and modified them so I could have a really good reflector.

Hope this helps, Frank

Frank,
Thanks for the info. I was hoping this portion of the wing build would be relatively easy. I guess not.

I have halves of my ailerons built. I'm waiting on the RDS hinging system to complete the install. I will begin building the flaps shortly.

Mike

Mike;

Be careful of potential flutter as this mechanism is a spring and unless the actuator wire is VERY stiff it will flex with excessive load like high speed and begin to flutter!! I thought about using this system too but I have too much invested to test a theory.

Frank

UkerDuker

My Feedback: (3)

Frank,
Are you serious when you mention "high speed"? I agree the connection will have to be stiff, but I doubt we will achieve speeds that will create flutter. I sure won't be flying my project like a 3D plane or a jet. I plan to fly this strictly scale. If I am doing a roll, I have lost control. The way the RDS system is setup, I think this will be a great solution to hiding the aileron linkage and delivering solid control. Once I receive my setup I will report my findings.

I have shifted my focus to my GP Patriot 40 kit until I get my parts in.

Any progress on your plane Mike or Frank? Haven't seen anything new so I just figured I would bump the thread back up at least.

UkerDuker

My Feedback: (3)

No real progress from my workshop. I have been working alot lately and have little time to work on my Herc. I was hoping to get my outboard flaps started. I guess I am just stocking up on parts for now, until my work schedule slows down.

Frank should be ready for flight as fast as he is building.

Mike

FYI, if you want something beefier for the RDS:

I'm gonna order a couple myself to try them out: the nylon gear set doesn't inspire enough confidence for me.

Thats a much better setup, in regards to strength. The only down side is there is no adapter for a JR servo. [:@]
