I've finished working on the CAD files from 3-views for the Edge540. I'm going to be using one of my 2 MDS68's, probably with a 14x4 prop, but I'm having a hard time deciding which of these scales will be best suited for this engine:

18% --Span: roughly 52.75 inches
19% --Span: roughly 55.5 inches
20% --Span: roughly 58.5 inches

What weight should I be trying to keep a 60 sized ship under for good 3D/funfly performance (I'm guessing 7 pounds). I've been spending the last few weeks all over the web looking at "60 sized" ships, but I see most stuff a .91 or 1.20 in them and most of these birds are in the 60 to 70 inch span range. I want to see a 60 sized bird with a 60 to 70 motor in it! Can anybody give me some input if you have a 60 sized bird with a 60 to 70 motor in it and the span and weight of it? I'm thinking of dual elevator servos, so I'll have 6 servos in this thing.

A soon as I get this figured out I'm ready to start cutting.

i would think the middle one 19% one you would have the light wing loading and still be big enough to see well the hangar 9 cap has a 60 inch wing and it has a mds 58 not unlimited weight about 6 and 3/4 pounds probly a little more happy building

I built the GP Cap w/MDS 48 at 4.95 lbs. The question is how disiplined are you about saving weight?

The MDS 68 is very powerful if you use the stock muffler.

If you use nothing but 6-8lb contest balsa, use your scale, the lightest balsa square and tri stock, (w/uni carbon on spars), 4 Hitec 225's, a HS 81 for throttle, foam wheels, 1/8" lite ply for firewall and landing gear plate only, (with lightening holes) only use epoxy for ply pieces, lithium batteries, and a simple covering scheme.

You should be able to build a 67" at around 6.5 to 7lbs and be completely unlimited.

Now that would be fun!!!!!!!!!!!!!!!!!!

I would buy one!!!!!!!
