The Sr-81 was a disaster......only because I'd neglected to do routine maintenance on my CNC machine....nothing fit....so,

Back to tried and true methods......I found a 2-off from the early 1970's......the Northrop YA-9, which lost the competition to the A-10.
First blush is a 48" span with twin 70's (y'all know how I like my twins).

Generating the parts, pieces, templates today..will cut it out this week

Less than an hour....(2)small piece of 1x6 common pine, and one of those lawnmower frame T-bolts with knob...Ideally, the little "keeper collars" should be brass to better accept solder..but you get the idea

I got tired of wasting aluminum and or music wire trying to bend landing gear with a vice/pliers/hammer....So I built a 2 ton hydraulic press brake out of materials readily available at HD/Lowe's, and that doesn't require any welding and or special tools....worked like a champ..so I decided to build a wire bending tool.....same deal, no special tools.....drawings are included.....The press brake cost me less and $50 and the wire bender less than $10.....

Y'all have fun

On the downwind leg, my instructor shut down the port engine, and wouldn't let me relight........like flying a drunken whale with a hard starboard list.......

A300 Airbus, 07L Hong Kong Port engine out (2 min 23 sec)

One last time......

I got to fly for close to 2 hours with my best friend, swapping off take-offs and landings out of JFK and Hong Kong.....Our instructor is a fabulous person, but he has a mischievous side....on the downwind leg of my approach to 07L at Hong Kong, he cut the port engine on me...a bit of right rudder and and a little left aileron fixed that, but she (an A300 Airbus) was wallowing around the sky like a drunken whale.....exciting wasn't the word for it....

But I still painted the landing.........while both my friend and instructor were laughing their butts off....As a note we never flew with autopilot or auto land......the realism is amazing...sadly our instructor is moving on to fly commercial.....best of luck to him
