RE: 2 for 1
i've been through tons of hot's in my time, all one piece with clipped wings and piped YS .45s.
first one had a single standard servo, no lack of torque but serious flutter problems. all my hots after that got a pair of standards or airtronics 401 minis and both worked fine.
also be sure to seal your hinge gaps. i cover the wings and ailerons after hinging
