About this Plan

C-130E Hercules. Radio control scale model for electric power using 4 x 280 can motors.

Quote: "Build it! C-130E Hercules. A multi-motor 280 powered model of a true military workhorse. By Keith Sparks.

This project really started when I built a Multiplex Twin Star to learn about multi-motor electric flight. The Twin Star is a high wing, twin engine, foam airplane with plenty of power and very forgiving handling characteristics. Importantly, it provided me with lots of fun and many lessons-learned.

I used those lessons to design and build my C-130E. It has a good power to weight ratio, flying well even at 1/2 power. It is as forgiving as the Twin Star. But this electric Hercules is not as aerobatic because of its wing span. However, it will loop, and slow fly-bys and touch-and-goes are very impressive too.

Construction: The construction method I describe might seem unusual, but it produces a semi-scale, lightweight, low-cost aircraft.

Fuselage: I began by transferring the pattern of the fuselage from the plans and the inner cavity to a 2-inch sheet of white expanded foam board. I used a scroll saw with a fine tooth blade to cut the left and right halves of the fuselage.

To remove the foam from the center section of the fuselage halves, I used a 1-inch diameter, 100-grit, drum sander in a drill press. By adjusting the height of the drill press table, I was able to set the amount of material the sander removed. Two passes were required to achieve a fuselage wall thickness of 3/4-inch. Take care around the areas where the lite ply wing-attach-plates go. A mismatch here causes problems with the bond later.

I temporarily taped the fuselage halves together to sand-out any irregularities: 120-grit sandpaper worked well. Next, I marked the locations for the landing gear plates. I used a Dremel and router bit to cut the groove.

Bond the fuselage halves together with 30-minute epoxy. Tape them together with 1-inch-wide masking tape until the epoxy cures. Avoid getting the epoxy too close to the outer edges of the fuselage - it will make sanding easier later.

Make the radio hatch from a piece of foam scrap. A tight fit is required to prevent the hatch from blowing off during flight. Use 120-grit sandpaper on a sanding bar to 'true up' the top and bottom of the fuselage. I sanded the taper into the nose and tail as per the plans, viewed from the top. Sand-off the upper corners of the fuselage next. Do not skimp here or your 'Herc' will look boxy. I used photos and drawings to determine the Herc's nose shape: 180-grit sandpaper, worked slowly, got the shape right.

Before adding the wheel well fairings to the fuselage, cut them out with a hot wire and shape them. Make the contour by wrapping 180-grit sandpaper around the fuselage and using it like a sanding block to shape the inner surface.

Bond the fairings to the fuselage and then use a Dremel tool to clear the holes for the landing gear. Several test fits of the landing gear and their wheels were done before I epoxied them in place. Note: Flip the fuselage over before the epoxy cures and lay a straight edge on the wing saddle to make sure it is level. Adjust as needed.

I used 280-grit to 'smooth up' the fuselage. I epoxied a piece of sheet plastic disguised as a VHF antenna into a slot cut in the top of the radio hatch. It acts as a handle, too. Then I installed the wing attachment plates..."

    ScaleType: This (oz12727) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Lockheed_C-130_Hercules
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
