Band Boy (oz1732)
About this Plan
Band Boy - Single channel radio control model, for 1-1.5cc motors. Aeromodeller, January 1961.
Quote: "A 36 inch simpleton for Sunday session sport flying - with or without radio-control.
FOR THE CHAP looking for a small, handy sized, second radio model to take along as a 'spare', Bandboy fills the bill admirably. If you want a model to do upward inverted tail-first flick half-rolls there are other designs which might make a better showing, as the combination of dihedral, wing and tail sections, moments and areas used in Bandboy add up to an easily trimmed (but lively) sport flying model - in fact, it makes a rugged little sportster for free flight if you are no radio fancier.
Empty weight of the completed model is nearly 16 oz and it is suggested that radio weight, if carried, is limited to 8 oz, giving a wing loading of approximately 16 oz/ sq ft. Half a pound of radio covers the Reptone unit, and this is about as small a model as will comfortably carry this one-piece outfit. Alternative installations are shown on the plan, and those with a little experience will soon find that the trapezoid fuselage cross section will obligingly accommodate quite sizeable equipment, always remembering the advisability of keeping a weight limit, while still retaining apparently slim lines.
There is little unusual in construction. The fuselage sides are cut from 3/32 by 4 in medium hardish sheet - no need to use rock-hard material, as local reinforcement by doublers etc. can be used round areas of stress. Bind the undercarriage in place on F2 and F3 before assembling the fuselage; double cement all joints - it's silly to attempt to prevent the structure breaking only to have the joints give.
If you are fitting radio, plan out the installation and carry out as much work as possible inside before sheeting the bottom. If you wish to follow the Reptone style of installation, cement the 1/4i n square strips and inner skins in place, sand flush, and sheet the bottom with fairly hard 3/32 in grain across. A scrap of silk or nylon reinforcement cemented round the corner will prevent the bottom falling out in any but the heaviest landing. An alternative means of access is to make a tapered tray fitting up into the bottom of the fuselage, dowelling it in place. In this case reinforce the insides of the body with 1/32 in ply or celluloid so that the dowels will not tear out.
After sheeting in the bottom, make and fix the fin. Cement the spar and ribs to one sheet, add the tape, then position the other side and clamp with clothes pegs till dry..."

User commentsHello Steve and Mary! Here are some pics of the Band Boy by Vic Smeed that I built for the 2016 Complete a Project Build-off on RCGroups [more pics 003-006]. It just needs a bit of final adjustment. Flying is very relaxing, but it can also do simple aerobatics like loops, inverted flight etc. I modified the stabilizer to a simple plate profile and reduced the incidence of the wing to 2 degrees. Engine is an 1,5cc Enya with 60cc tank, which gives between 15 to 25 minutes of flying. Wing spars are 5x5 mm spruce with 5mm beech dihedral bridge between. Weight is 730g. Here is a link to a short clip of the second flight: www.youtube.com Thank you both for the time and effort you put into the Outerzone site. Special thanks to Mary for supporting Steve :D Best regards from Germany,

* 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.
