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.

Note the plan shows two separate fuselages, for free flight and RC version.

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 6 feet plus but not 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 straightforward 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 off we 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, check-for warps though.

This fuselage is built from the bottom up. Lay out the bottom longerons on the plan view, pins either side of each. Glue in the 1/8 ply engine plate and the formers F1a to F6 inc, ensuring they are upright and square, then the bottom cross-pieces and tail block. Make up the top longerons from the side view - the scarf joint needs to be accurate and yes, it is essential to keep the wing seating flat and preserve the straight line to the tail. Glue the top longerons into the top corners of the formers and secure the tail end of them with the 3/16 gussets. Leave for several hours.

PVA is recommended for most of the building; a variety with 'fast grab' and sandability is best. Where 'epoxy' is mentioned a tough slow drying one such as Araldite Heavy Duty is required. All joints should be clamped, where practical or, weighted down.

Once the basic frame is handleable you will, I hope, see how true it is. Add the rest of the cross-pieces; glue and clamp Fl to the face of Fla, glue in the gussets, line the cockpit well and, turning it over, add F6 and construct the keel together with the skid. Make up the fin and rudder over the Plan and leave aside under weights to ensure it dries flat. Note that the central dorsal upright will go down the face of F6 when assembling later.

Tailplane: Cut out the centre 1/16 sheet panel and pin it to the plan. Build the bottom parts of the outline around it from 1/8 x 3/8 spruce, the tips from 1/8 x 3/8 balsa. Gently sand this structure to ensure, so far, that all joints are smooth then glue on the 'false' 1/8 x 1/4 in LE and tip laminates and the 1/16 x 1/4 in TE lamination. Add the three bottom outer 'ribs' only at this stage but put the spar in too.

Lift the whole assembly off the plan when dry and glue it well to the rear fuselage ensuring it is central and at right angles to the fuselage (always mark C/L on tails, wings, and fuselages!). Now, out with the cyano to fit the remaining 'ribs'. Top 'ribs' are best cyanoed to the LE as shown, first then bent down to the TE over the 1/8 x 3/8 spar and glued there. Cut the 1/8 support blocks to match the profile formed by the natural curve of the wood, and fit them. Then cyano to the spruce spar, the underside of the 'rib' and the mainspar rib joint. Now sand the LEs down to match the curve of the ribs, trim the ends of the spar to blend in with the tips and round them off. Round off the TE... "

Note: This is an incomplete plan, see comments [edit: fixed now]. My mistake. Will hopefully add the missing parts as and when we get them. Steve.

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

Update 06/09/2019: Added the 2 missing sheets now, thanks to KraftyOne.

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

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.
GeoffO - 02/10/2017
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.

I am looking to build the Oddie 94 (one of many). Having downloaded the plan it would seem that it does not show any of the main wing construction - unless it's me! Could you advise? Have tried looking through all the updates etc. Keep up the good work, this is a wonderful site.

Like I said in the previous comment, we are missing 2 pages of this plan. Not sure what other advice I can offer.

Hi Steve, As Prof H.J. Farnsworth would say, "Good News Everybody", (and it nearly didn't happen). I have to clear out years of hoarding and came across an old style model plan with no identification at all on it. I tossed it in the discard bin and carried on. Much later I found the ODDIE 94 plan, turned it over to look at the wing plan, and found "Boddos" Tinkerbell plan on the other side. What!! Oh well, that's another one for the bin, but fortunately I checked your database for ODDIE 94 and the penny dropped...
Sheets 2 & 3 have been rescued from the bin, I'll get them scanned and over to you ASAP.
Cheers, Eric.

* 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.
