I had a Phantom more years ago than I want to admit to and when I saw the other thread about this sweet little aeroplane I couldn't help myself from doing one. A while back one of our brethren kindly sent me a plan of a Phantom Mite... and another sent me a copy of the original Phantom with templates. Well I have mixed the two, and added a few of my ideas so as it's not made out of so many "Planks" ... A hybrid if you will.
This one's fuselage is mostly made from 3/32 balsa and some ply for the U/C sandwich. In fact I am able to get every thing needed from one sheet of 4" x 36" and have plenty to spare.
The wing is 1/4 sheet with a piece of spruce as a 'spar' between the front 1 1/2' and the back 3" giving a cord of 4 & 9/16. The span is 500mm, hence the name Phantom 500
This one , the proto-type, I am building for a Sure Start but I'm designing for the possibility of using many different power plants ranging from the basic Cox (Sure Start, Killer Bee or the Cox 049 Reedie that you can put together out of parts in the forgotten draw) or the TD 049 and 09 along with a "Mighty " Merlin or what ever you have laying around in this general category.
As I go along I am going to have questions as this is the first C/L model I've built for quite a while. 15 years or so.

The first one is about bellcrank size. I have a Perfect #222. Is it too big at 2"? I like this one as it has a bushing but should I use a smaller unit?
#2... Lead out guide material and position?
#3...How much tip wieght?
#4....U/C wire size... .074 or .093. recomendation on which wheels to use.
#5....Tank size. I have old Perfect #20's, 3/4 oz wedge tanks and a new Brodak #520, which I am leaning towards. Comments, Please.
