What engine do you have.? I dont think that I would climb quite that steeply, say 50 mph with my Jabi. With our high thrust line the nose will tend to come up abit if you suddenly lose power making a potentialy chancy situation just a little worse.

With our high thrust line, if the engine barfs when you are in a 40 or 45 mph full throttle climb, it only takes a couple seconds for the airspeed to fall to zero, and the resulting stall is quite a dandy. > So I got serious a couple years back about occasionally practicing "engine barf recoveries" at altitude. My experience is that if you are in a steep full throttle climb and snatch the throttle back to idle, you need to immediately go to full nose down stick and even then the airspeed will go to about zero. > Meanwhile, the airplane feels like it is simultaneously decelerating and rotating around the main spar.

I will say (heresy coming!) that the ASI doesn't tell you much in the recovery so it's better to rely on AOA maintenance skills instead. I.e. I had seen the ASI read 40 even tho I was still basically in a stall. My FS II required a fair bit of forward stick for a few seconds to truly get flying again. Trying to restore level flight too early, particularly if you're practicing recovering without adding power, can get you into a secondary stall. But most high engine pusher light a/c I've flown, even my titan, are like this so it's just part of doing business in a stall.... It's actually amazing how much altitude you really need to recover tho. For that reason, I adopted a flatter climbout at higher airspeed in the FS II just in case. I do this even in the titan.

Steel lines to motorcycle braided flex. I didn't want to work harden the steel. DSCN1768.JPG the cart was about $35 at harbor freight. Saves my back pulling it into the winter harbor.

Can't tell from the photo but is the drain plug offset to the side of that brace? Just wondering what oil changes will be like with the tank up there?

I'll probably machine a 90deg extension that will fit in the bottom of the tank and install a Curtis drain valve in the other end. Then it will be a simple matter of hooking up a hose, then opening the drain valve. > > > Can't tell from the photo but is the drain plug offset to the side of that brace?
