Scored A New Sig Magnum Still In The Wrapper

[Dick Pacini]

By chance I saw it in the classified ads here on the forum.  I have always been curious about this airplane, so when one cropped up, I was all over it.

Impressive kit.  Foam wing and tail feathers,  nice building manual and decent hardware.  The packing in the box was a 1993 newspaper wadded up, so this puppy is old enough to vote.

So, It took its place in the rack.  Anybody have good stories to tell about it?  Strange that Sig dropped it.

A number were made and flown here in NorCal, including one by myself. Only tip I might throw in is: the wing is hollow, a little too hollow. One large hollowed cut out. If you use the kit wing cut a foam "spar" and insert it into this hollow to keep the airfoil from flattening out later on down the road.  For rough field use I'd go with CF fuselage mounted landing gear. Engine wise, I'd use good ST G-51 but there are many that would work well.

Don't put the landing gear in the wing.

[Glenn (Gravitywell) Reach]

As per proparc....DO NOT PUT THE LANDING GEAR IN THE WING.....and do put in the spar as well.  I both ripped out the landing gear and wrinkled the skin on the wing cause of flexing.  Loved the plane though!

I flew a nice Magnum with a Double Star 54. The model was quiet a bit nose heavy so you may want to look at way to mitigate the issue. See if the wing can be moved forward 1/2(more if you are planning to use a heavy motor like ST51).

By the way. Double Star 54 has got to be THE MOST underrated motor. It weights less than 9oz(with TWO ball bearings!) and makes the power of a ST60.

An easy way to cure nose heavy and to help the plane fly better.  Add three inches to fuse length and move stab/elevator accordingly.

Hi Dick!, Go to builtrightflyright web site and after entering pick "helpful hints" at the bottom. You will find a list and at the bottom is a big build article by Walter himself about the Magnum. EXCELLENT!---LOUIE

I had two Magnums with ST-51, great combo. 
Others had always told me the stock kits build on the heavy side. 
Mine came out 62 and 64oz. 
That's not even close to heavy for 700 squares.
I also got one still in the shrink wrap about 4 months ago right here in the classified.

Too bad Tom doesnt have a rear exh version.

Instead of using dope or (far worse) monokote to cover the built up flaps, try planking them with 1/32" balsa or 1/64" plywood. You'll be much happier with the result.

Power with an ST .60 if you can find a good one.

Not a good candidate for electric power, I'm thinking. But I've been wrong about such things before.

The Magnum is just a big old sweet flying pussycat of a plane, which goes right where it is pointed. With a larger motor, it will pull your arm out of the socket.

Mike Pratt's excellent design.

Mikey's MAGNUM Force (top), and Profile FORCE (w/Chip wing) bottom. Magnum was powered by a Piped P.A. .61. The little guy by an OS .32 on a pipe.

Hi Ward,

How well does the Delta FORCE turn?

[Ward Van Duzer]

Sorry, can't answer that. That's Mikey's ship. He knew I was a Force Fan and sent that on to tease me!

I remember when he had the Delta Force at a VSC a few years ago.  Have been waiting for plans or details ever since.
