Indora (oz2890)
About this Plan
Indora. Indoor chuck glider.
Quote: "Indora, by John H Dixon. Ever tried an indoor chuck glider? If you use a clubroom with a fairly high ceiling you don't know what you are missing, and we suggest you reach for a sheet of 1/32 and 1/16 light grade balsa plus a length of x 1/8 x 3/8-in hard and get sanding on this 15-inch flyweight.
John Dixon designed it for 40-50 ft ceilings, and its best time at the Manchester indoor meeting was 41 secs, it actually won the contest with a best official timing of 30 secs.
To get that airfoil camber, taper the sheet at leading and trailing edges on the top surface, and rub the wing (in one piece) chord-wise over the edge of a table. This gives the required undercarnber and when the wing is cut and fixed with polyhedral, the joints, aided by a 1/16th rib at each root, keep the section.
The rest is plain sailing - don't dope it, simply sand as smooth as possible, add the weights for balance and trim, then throw with a right bank to get a roll-out at the top of the climb."

The length of the fuselage is not mentioned in the text and the two sections of the fuselage drawn do not join up. The only way is to try and extend the tapers until they match, which is not very accurate. I think that there is a something like 70mm missing.Chris Pinn - 19/11/2020
Hi Steve and Mary, The fuselage length works out as 18 inches [main pic, 003,004]. I reinforced the bottom of the fuselage with 3x1mm carbon and the leading edge of the wing with 0.06mm Spiderwire. To get the curved aerofoil, I soaked the wing in water and taped it on an old Ace mini foam wing core leaving it on a radiator overnight. The best glue I found to build the wing was good old fashioned balsa glue (e.g. Uhu Hart). First test glides show a beautiful floaty glide.

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.
