About this Plan

DeeCee. Radio control sport model. Sport flier for .61 power.

Quote: "In designing this sport model several goals were established. They were: keep the weight as low as possible, keep the construction as simple as possible, give it acrobatic capabilities, and, most importantly, make its appearance pleasing. The model's name is taken from the initials of the club I belong to - the DCRO (District of Columbia Radio Control).

First of all let me make a brief comment on the airfoil and then get into the construction details. As you can see from the plans the airfoil is very thick. The airfoil used is the Eppler 473, a symmetrical section whose thickness has been increased from 16.19% to 18%. Over the years I've been favoring thick sections as they have suited my desires for planes that do not fly too fast and have docile handling traits. In this model these conditions have been realized. That being said it's time to start building.

In order to keep the weight on the low side be very careful in your selection of balsa wood by using light to medium weight stock.

Fuselage. The firdt step is to make all of the necessary parts. This includes sides, doublers, formers and landing gear blocks. Start by preparing the 1/8 balsa sides. As the fuselage is long it will necessitate splicing sheets together. I made the splice at the rear end where the size of the cut will be minimal and will be reinforced by a balsa doubler. The plan shows the splice based on the use of 48 in long balsa sheets. 4 inch wide balsa was used which will require the addition of some balsa at the front end to build up the width to the necessary profile.

After the sides are out to shape, 1/2 in wide triangular stock is added along the edges except for the area where the landing gear plate is located. This allows the corners to be rounded to give a much more pleasing look than if they were left square. To facilitate bending the triangular stock, kerfs are cut every 1/2 in along the curved pieces on the front end of the fuselage.

The next step is to add the 1/16 ply doublers to the front of the fuselage. Note that the doubler is short of the fuselage side along the wing saddle area. This is to make it easy to sand the fuselage side when fitting the wing to the fuselage. Make sure that you cut out the hatch opening from the left side of the ply doubler before it is cemented in place..."

Hi Steve, I was quite surprised to find one of the RCM 'missing' plans in one of the few mags I have left. Hopefully the "technicians" will be able to create a clean plan, but I was only able to upload a 1MB image, RCG would not allow any larger. Cheers,

Notes

* 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.

Scaling

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.
