Meson MkIV (oz1491)
About this Plan
Meson MkIV. Free flight gas model. Twin tailled low-wing, for 1.5cc motors.
Quote: "A successful low-wing free-flight monoplane of rugged construction.
The Meson Mk.IV is the latest of a series of low wing monoplanes, most of which were fitted with radio control. In its original form the Mk. IV was powered by the Allbon Javelin 1.49 cc but it has also been flown with equal success when powered by other similar capacity engines, including the new ball bearing Elfin 1.49cc.
Contruction is quite straightforward and combines simplicity with strength.
Fuselage. Cut the 3/16 in sheet side formers to shape and build the fuselage side from 3/16 sq balsa directly over the plan. The second side should then be built up superimposed on the first. Now mark the positions or formers E, F and G on the inner surfaces of the side-formers, and then cement the formers at right angles to one side, using a set square or postcard..."

I discovered a nice video of the Meson MkIV flying at 10:45 here: www.youtube.com Anyone sceptical about the stability of low wing free flight models should take a look at how well this one flies !!!ChrisPinn - 22/02/2016
Hi, in the picture you have of a young lad with his red & white Meson is my son Andy, he’d have been aged about 13 then. He still has the Meson.
I stumbled upon this by chance, I’ve sent him a screenshot and he looks forward to his royalties!
Regards,
Charlie

Some tips born of experience! 1. Strengthen the front end with 1/16" ply 2. Sheet in the first fuselage panels behind the wing; you will poke your thumb through 3. Try to keep the tail flat. Those diagonals do nothing 4. Reinforce the wing TE in the centre section - the bands cut in. It is severely underelevated, needing 5/16" packing. 5. Key the tailplane well.

Hi I am building this one using a Webra 1.5cc. I wil use radio assist for rudder en elevator. There is no CG on the drawing so I suppose 30% of the wing may be a good start but being freeflight it might be better to move it quit a bit to trailing edge like 60-70%.
Any one any experience?

Hi Mary/Steve, Please see attached some pictures of a friends (Allan) Meson, an excellent flying model [main pic, 006-009]. This model is powered by a 1.3cc Mills diesel. If anyone wants to see a video of it flying there is one on my YouTube Channel, here is a link: https://www.youtube.com/watch?v=SwJARE5ORN4
Best wishes,

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.
