I just close my eyes and pray
The LHS must love you.

Re landings tho, I'm still figuring the things out really... I was taught to idle the throttle as I turn onto final and use the elevator to bleed off speed which seemed to work fine on trainers but was less successful on sports planes. I read up a lot on landings and put in a bunch of simulator time teaching myself to use elevator to control attitude and throttle for descent rate which seems to work a lot better on my Super Skybolt and Dual Ace. Ailerons are only to keep the plane level and rudder's for heading.

I recently dug my old Harmon Rocket 3 out of retirement, repaired the muffler and got it airborne again which upset my nice tidy landings as the thing just doesn't want to slow down but floats 3' in the air most of the way down the runway before burying itself in the longer grass as the end of the runway (thankfully it's soft grass ). Slowing down earlier to get the approach speed lower isn't really an option as the short stubby wings give it a fairly high stall speed, and using the elevator to bleed off speed when it's being "floaty" will make it balloon and stall. After looking at the similarly sized Great Planes RV4 kit (from which the real Rocket 3 derives) I finished kit-bashing some flaps into it yesterday to help slow it down, and am just waiting for the rain to clear so I can test fly it - hopefully tomorrow. I'd tried flaperons and all they did was make it floatier and reduce the aileron efficiency due to the shallow flap angles I had to program in to keep some aileron control. Hopefully flaps at 15 degrees will lower my stall speed, and at 40 degrees will drag the plane to a stand still so I can get it on the ground. Either that or I'll plow it into the threshold nose first and that'll resolve my problem permanently.
