Boomerang1...Thanks for the info. Here's my second flight report.
Flight Report
Weather conditions were good about 85F degrees, winds about 7 to 8 kind of cross the runway, but at an angle.
All repairs completed from maiden flight. Engine (OS 55 AX) was richened a few clicks, it was dying about 70 yards (210 feet) down the runway. After that lined up again for lift off. My Bobcat ran about about 85 yards (255 feet) before launching into the air, almost vertical as on my maiden. I don't like that. As I mentioned in my initial flight report, I believe my Bobcat is nose heavy making it difficult for the nose to lift without giving an extreme amount of up elevator to get it off the ground. I was ready for the leap so it wasn't as vertical as the initial flight.
After leaving the ground and levelling out, hit the switch and brought the retracts up. Boy does this thing look cool with the retracts up. Was cruising around just to continue to get the feel for this puppy. Did I mention this thing is fast. Well this thing is fast. I don't know why anyone would want to go faster with a Tower .75, well I kind of know why, but don't understand why.
I performed a few aerobatic manuevers. Roll rates are insane on high rates, so insane I'm not sure was I finish rolling whether or not I right side up or up side down. That's scary. Roll rates are extremely fast or low rates. Basically I come down the runway WOT and then snatch up elevator, half way up I would give right aileron and do somewhere between 10 to 15 rolls before hitting the top of the loop. Depending on right side up or down, I would spin once more on the down part of loop and level out.
Now for the imfamous landing. I believe someone has this as their signature, "Take offs are optional, but Landings are Manadatory." Since it was the second flight I didn't want to over do it. Flick the retract switch and did a low pass to verify that they did indeed come down. Began my approach/line up passes, and finally saw one I liked and began my landing. Our runways are about 10 yards (30 feet) wide, I was lined up about 10 to 12 feet from the closes side of the runway to me. As I got closer to runway, I would say about 4 feet off the deck a nasty cross wind came up, I was thinking not now, my AOA for landing was near perfect. This moved the the plane to about 4 feet from the high grass. The plane continued to weatervane into the wind just as the rear wheels touch the ground after about 2 feet the nose wheel touched down. At this point I was not even 1 foot from the high grass, the right main caught the high grass right in front of mee and then the nose wheel caught the high grass. Once that happened the Bobcat stop and flipped over, motor still running. I hit the kill switch to shut it off. Now for the damage:
Damage Report
1. The came apart toward the leading edge, I think this was due to the hot glue not really securing the front screw brackets, nothing epoxy can't fix.
2. Bent right main and nose wheel struts shaft, nothing a hammer can't straighten.
Flight lasted about 6 mins, I emptied the tank on the flight station. The amount I removed would have lasted about 1 more minute. All in all I consider both successful flights, with eventful landings. I will have the wing bracket epoxied back in and retract shaft straightened by this evening 8/15. I think I'm going to put 3/16" music wire in my retracts instead of the struts, since the wire may be a little more forgiving on the landings until I get a better feel.
Hope I didn't bore you. Just wanted to be thorough for any trying the Bobcat for the first time. I must say OPJOSE warned me that the Bobcat is quite different than any other plane in my fleet. Now I know exactly what he means.
