About this Plan

Oddie 94. A 39-1/2inch wingspan model for free flight or radio control using .75cc diesel or 1.5-2cc glow.

Quote: "As a non-prolific producer and flyer of my own designs since 1938 and, some would say, all avowed follower of the Vintage Movement, mainly R/C, I needed a small vintage type to fly at those few meetings where R/C is not appropriate. I have found great pleasure in endeavouring to reproduce British models from the '30s, they take me 3 or 4 years each so, it was time for an 'OD' to satisfy a particular flight envelope: Must ROG and preferably land right way up! Must climb fairly rapidly to plus but IRA thereafter (circuits at a head height can be dangerous!). About 50/50 motor run to glide ratio with slow power on performance with some realism and hopefully an aversion to thermals.

'Oddie' is not for high winds but copes well in a moderate breeze and turbulence on its original Mills 75. Stability is very good, she will turn in either direction and the heavily reflexed tips and rudder mainly out of the prop wash, give a straight take-off and climb out followed by a stall free entry into the turn helped by the lifting tailplane. It's also rather nice when people say it looks good in the air and: where did you find that one; how old is that?"

The R/C version has a long history with a different wing but flies
much better with this one. It is just as docile as the FF version, copes well with quite windy conditions and makes a very good ab initio trainer with low initial and running costs since standard size RC gear and a big battery fit with room to spare. It's tough too and easy to repair. It will loop, roll, and spin in a quite gentle way.

Building is straightforwatf but it's not exactly a first model. So, I'd advise reading all the instructions first whichever or both version you've decided on then, cover the plan with clear polythene or, candle wax all the joint areas and offwe go.

F/F Fuselage, Tailplane and Fin: This is built with the tail integral with the fuselage to ensure strength and rigidity where the trim won't change from one outing to the next. The more predictable a model's flight pattern can be made, the safer it will be. Still, cheek-for warps though..."

Note: This is an incomplete plan (see comments). My mistake. Will hopefully add the missing parts as and when we get them. Steve.

Update 18/03/2019: Added article, thanks to RFJ.

Doh, it does seem like the wing is missing from this one. Thanks Brian for pointing this out. Anyone have a second sheet for this one, showing the wing?

The wing plan details appear to be missing. There is no reference to a second sheet on the fuselage plan.

There are two other sheets for this plan Steve, one for the wings and another for an alternative fuse for RC.

Ok, this was my mistake, sorry about that. We are missing pages 2 and 3 of this plan. Will leave this (page 1) up here here for now, and see if anyone can send in the missing parts over time. Thanks guys.

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.
