My hinged suffaces were good. I just never know how hard to pull on them to give them the "test"...... I made my pull-pull tail wheel set up and it works great... had to cut out a hole where the tail wheel is mounted and run plastic tubes for the cable to run through to the rudder servo, then balsa it back and cover it, but it was worth the hassle..

What engine are you going to use??

Thanks,
