Well I've been pretty quiet. Some of you may know me from my yellow L-13 at mike Sizemore's flyin a couple years ago. I'm Clu Colvin A couple of years ago I bought this airplane on amphib floats. It had a V-6 ford on it. It began life as a sportsman 2+2 that was reengineered 7" wider 9" taller and 12" longer. With heavier struts and tubing throughout the structure along with doubles on the spars. It was originally built in 1992. It is 45" wide and has a full length double floor baggage compartment to accommodate 2 sleeping bags and a pop out back seat.
I was never much of a ford man especially on the front of an airplane. It ran fine and performed ok. Just not for me. I took the engine and prop off and started building new firewall forward. It now has basically a IO-520D on it with my own twists. Higher compression pistons ground the cam for more overlap. Ported and polished balanced everything. And a Rotec throttle body injection that runs off of gravity feed or pump. 88" McCauley constant speed prop. I'm still in the lightning it and still néed to paint the cowl. But I have about 5 hours on it and its used less than a half quart of oil not bad for break in if I do say so myself.
With 10" gar aero and 8.50x10 tires on it and of course on its Gear it weighs in at 1447lbs and empty CG is at 7.4 but as soon as I set in it it's in CG. Preliminary numbers so far:
cruise at 2300 and 18" is 135 mph
takeoff with me and I ain't small and weighted for 200 extra pounds and full of fuel just 36 gallons is about 200 feet max without using the flaps.
Rate of climb pegs the vsi on 2000'fpm at 125 mph.
Just put on VG's and gap seals and haven't tested yet
yet the video was taken with a phone I'm not tech savvy so it may not play. My mother taking it was standing about 250' down the runway. Some of you will think its a waste and heavy. But it's just my version of a 180. I will be putting it back on the floats after I get some more time on it. The name Super Chub 520 is to bug Brandon Jewett that my chub will always be bigger than his!
