About this Plan
Mojo. Free flight rubber sports model.
Quote: "AFTER BEING an Aeromodeller for over 25 years and progressing right up to R/C flying, I suddenly realised one day at the flying field that I was taking my hobby too seriously and that a lot of the genuine fun was lacking. It was while watching a small rubber powered model flitting round the evening sky that made me decide that I had to go back to some basic modelling and flying to bring back some fun and to give my son the opportunity to learn something about the hobby in which he was then only qualified as a fetchamite.
Out came some scrap paper and after many doodles I finally arrived at a design that had a very basic type of construction but looked more up to date than a lot of the established small rubber models. I dispensed with the undercarriage because of its extra weight, it looks ridiculous with a long spindly wire U/C and when it is hand launched it has a headstart of about six feet altitude anyway. Mojo incidently is a good luck charm.
Now lets get started on construction. The choice of balsa for the fuselage is, quite important in that the upper longerons have to be stiffer than the lower ones to keep the whole fuselage straight.
Fuselage is very straightforward using slab sided construction, building one side over the other, After the sides are complete and removed from plan, cement F2 & F3 to one side ensuring that these are square. When dry, cement the other fuselage side to F2 & F3 all the time making sure everything is square and that it 'looks right'.
When the cement is set, pull the tail end together and cement, holding it with a rubber band. F1 can also be cemented into position at the nose once again holding with a rubber band as pins can split the balsa at the ends if they are used. When these are dry all the cross bracing can be cemented into position and the sheeted areas positioned and cemented. Make sure that the two cross-braces running parallel to each other at the front of the windscreen are only cemented at their ends because the tab on the windscreen forward end is eventually cemented between these braces.
The nose block and prop assembly can now be made up and the right amount of downthrust is incorporated. The wings, tailplane and fin are quite straightforward, the only point to watch is that the two wing halves are square to each other when the rod end ribs are joined, ie they both have the same incidence..."

Corrections?
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

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.
