Giant Scale Spitfire (Thrust to Weight Ratio)
Hey guys!
Ive been building a giant scale spitfire with a wingspan of around 81 inches. It's estimated weight is around 15-16 pounds with about 15.5 pounds of thrust. The wing loading is going to be around 39 ounces a square foot. It has a cubic wing loading of 15.9
Is this a good thrust to weight ratio for a Warbird?
What is a good wing loading for a plane this size?
With these statistics will this plane stall easily on landing?
Thanks, any information would be great!

Spitfires are notorious for tip stalling UNLESS you box clever with a change in wing section from root to tip and build in some washout.
Keeping them light helps. 81 inches and 16 lbs well it is not light but not particularly heavy either.
Nice gentle climb out on the first flight and explore the stall characteristics 3 mistakes high. Watch out for the high g tip stall which will produce snap rolls.

The normal practice is to raise your ailerons say 3 deg, mixed to a switch. Each wing/aerofoil has it's particular quirks... ask in the scale/warbirds section for advice from those that fly/compete with Spitfires.
