Hey Guys! I haven't been on for quite a while. Have a question for all you FlightLine F4U fans. Was checking out the gear on my bubbletop (which I haven't flown for a while) and it seems to be struggling and vibrating when I cycle them. They eventually open and close fine but they vibrate and shake which I haven't see before. It almost seems like they need lubrication or something. They just aren't opening as smooth as they used to. Could it be due to sitting for a while and not cycled? Appreciate any suggestions. Thanks! Grover54

You'll have to take them out and inspect them while cycling them via a servo tester and looking with a magnifying glass for the fracture to open up as they cycle. See where all the moving bits are and dab some light machine oil or silicone onto those areas, keeping away from the little circuit board. Last option: buy new retracts.

Death of a Corsair. Flight number 3 on my sons Corsair didn’t end so well. It took off, motor started making noises, a little smoke, and lost all power. It flopped in at the end of the runway and started to smoke. In a matter of a couple of seconds it was fully involved.
I've been involved in the hobby for over forty years. I’ve never had an airplane catch fire let alone burn completely down.

Seriously though, sorry to see that. The fire was most likely caused by a short or other breakdown in the ESC. I had a Castle ESC burst into flames in my 60" Beast Bi-Plane once, but it was cause by the idiot mechanic (wait a minute, that's me) that was prepping it for flight and plugged in the Sound card with the JST connector reversed so it was - to +. Got the fire put out quickly and only "fried' the ESC before the balsa or monocote caught fire. No other damage but it still smells a little "smoky" when I remove the battery hatch to put in a new battery. Kinda gives it the "smell" of realism.Hugh "Wildman" Wiedman

Back in May my Corsair burned up after I compromised the battery casing. I guess I was a little ham fisted strapping the battery in and the metal buckle on the strap was at the corner edge of the battery. Within seconds of strapping in the battery battery it lit off and by the time it took me to run to my truck and back to get my welding gloves to yank everything out this is the damage.
last year on of our Pattern flyers was beginning his routine when his plane started smoking. By the time he got down and stopped his nice Pattern plane was pretty much toast. He had used a new method of securing his LiPos which had compromised the outer casing on both batteries and let the magic out.

Yowza! Sorry to see that! Wow, a pretty spectacular way to go. I suppose it could happen to any one of our models at any given time. Again, sorry to see that happen.My YouTube RC videos:

grover54, when my fl spit reached 100 flights the retracts started jumping as they came up and down. did not take long before they were dead. assuming I had bent the screw I checked it and it was still straight, I found nothing mechanical. later when replacing another pair of large t-28 retracts I got the idea to check the brushes. turns out the brushes are pretty whimpy and as they wear the brush bends with landing force (i'm on grass) and they just stop working.
john, sorry for your loss!
when I was first starting to convert my alcohol to electric the first 60 size was a evergreen P-51B, I had converted from a D to a B and added flaps (it was made of wood). at a flyin a buddy and I were doing formation (more of an excuse to do worm burners). I was doing a full power split-s to a low pass and as I started the pull to level off to the runway I saw a faint white streak trailing my plane. by the time I was level with the runway there was no missing the smoke. by the time my bud reached in front of us I was banking out and prepping for a gear up landing. I got it turned around out away from everyone and just as it was about to hit I put the flaps down (a luxury only p-51's have) and there was a race to it. one guy with a extinguisher got there before me and put it out then a second just for good measure. and I carried it back and started the disassembly.
the cowl was fine, charred inside but usable. the motor looked good but wasn't. the esc was completely consumed with only the metal parts still intact. having been a alcohol plane there was a little hole in the middle of the firewall that all the wires went through and the part of the batteries that were behind that hole were destroyed, but not breached. it was pretty obvious the esc had been the cause. with a charred inside of the cowl and the firewall it was refitted and flown for 3 more years code named smokie. cause you just could not escape it's small.

Originally posted by xviper View PostYou need UP elevator for flap compensation? Usually, it's DOWN elevator since the plane balloons when flaps are deployed. It shouldn't be too hard to do a gear to ELE mix BUT, realize that the more you have to TX do, the more trial and error it will take to get things right. You'll spend just as much time bouncing around while trying to get the mix correct. You're better off to just practice your landings with different flap settings, different approach speeds and different throttle management when landing.
