Manx Monarch - BritPlan Build Off 2013

With snow falling and temperatures around zero now seems as good a time as any to retire to a warm workshop and begin my entry for the 2013 BritPlan buildoff.

Before I forget - many thanks to everyone who voted for my Veron Phoenix entry in the 2012 buildoff. To come second is indeed an honor considering all the other excellent models entered and congratulations to the well deserved (joint) winners and of course thanks again to George for coordinating everything.

Anyway, I have chosen the Manx Monarch this time or at least a scaled down version of it. The model was published in the August 1950 Aeromodeller as shown below. It was enormous - 9' 6" span - way too big for me so I chose a size that makes most economical use of 36" balsa wing sheeting. This produced a span of 64".

It weighed 7 lbs giving a wing loading of 11 ozs/square foot so my version will need to be around 2.5 lbs to match this.

First job is to draw an outline plan using the scale ruler shown. I tend to make up the structure as I go along but first thoughts would suggest a cap stripped foam core as the easiest option. We shall see.

The original had single channel rudder only R/C so I think I will do the same and just use the extended wing tips as elevators rather than elevons.

Going to be an interesting one Ray, and one of several tailless designs declared for the build off.

So that's what a Tadpole grows into!

Strange how the nose disappears, going to make for an interesting challenge to get the CG in the right place perhaps.

Like the cover illustration though with the Tx on the ground!

Cheers

That was probably just for the aerial, look at the length of that thing!

That guy would probably feel totally inadequate with today's 2.4 gear.....

Makes you appreciate how easy we have things today. By the time I could afford radio at least the transistor had arrived, so my McGregor Minimac was light and reliable.

This was the latest "miniature" version of the radio used in the original Manx Monarch and advertised in the same 1950 edition of Aeromodeller as the construction article.

Ray,
Very intersting project! Good luck with this one. I have a 46" version of this 90% finished which is where it has stayed for the past 5 years or so!!
I'll be watching with great interest as always!

Mark,

Yes, I remember that one, - a very nice build with a more "scale" structure than I intend to use. Was there a reason why you never got round to finishing and flying it. Seems a shame having got that far

Progress so far with mine is to cut out all the bits and make a start on the fuselage. I have also cut a set of foam cores for the wings.

Ray,
Im really looking forward to this one
Mine only got shelved because I ended up with so many unfinished projects all over the place.. but I will finish it off hopefully this year some time. It will be great to see your version. Its not a model I have seen built anywhere before. Have you thought about colour schemes yet?

I didn't realise it was so big! NOW, I'm interested.
Too bad it's not OT eligible in the USA. I wonder how high it would get with a McCoy and 25secs in Nostalgia?

Eut, will this thing fly?

Tom, I would have built one a long time ago had it been SAM legal.
