A full scale SE5a at 1410 lbs dry and a wing area of 444 sq ft had a wing loading of about 51 oz/sq ft if my calculations are correct.

IMHO - Your 1/4 scale at 22 oz/sq ft flying a 50cc, G-38 or Saito 180 should be flyable with power to spare. At 1/2 throttle (once airborne) I'll bet you model will fly very scale like.


I'm curious to get your actual flight characteristics now.
