    good luck

    Looks like a good plan, I'd be up for a couple of sets

      Here are a few things I've done with these cheap main gear retracts on the Corsair where you can get more use out of them before having to replace them. (1). Apply a THIN coat of JB Weld over the plastic case where it normally cracks on both sides. Don't cover up the screw holes or the seam! I even do this with a brand new retract right out of the package. They won't crack anymore! (2). The cam that travels on the worm screw gets "nicked" or "beveled" on the edge causing it to slip out of the trunnion from a hard (or not so hard) landing. That's why the gear just flops. It's made of cheap soft Chinese pot metal. Remove the 7 screws and slowly separate the two haves of the case. Take the cam off the worm screw and flip it around to the other side that is not nicked and screw it back on the worm screw.. (3). The worm screw gets bent from a hard landing. Take it out and try to bend it back as straight as you can. It won't be perfectly straight and it will cause the gear to studder (jerk) as it goes up and down, but it works and nobody is going to see it after takeoff or when landing anyway.😂

      If anyone can find better replacement retracts or even better CNC machined parts (worm screw & cam), count me in!!!

        DW, great tips and very doable for most. Bravo Zulu, Sir. Best, LB

          I just sent them an email asking what it would take to manufacture an upgraded retract, or at least the internal parts. I will post once I receive their response.

            I was going to order some spare landing gear parts "just in case". Do you recommend ordering the whole gear set (retract units + struts & wheels) at around $80 or just the retract units at around $40 ?

              Just get the retracts, however as of yesterday, they were not in stock.. If you have some broken retracts, try what I suggested in Post #4762

                Thanks. RC Castle have them both. I'm in NZ so I have been ordering from them rather than motionrc. Their prices are good and shipping OK.

                  I got 4 good flights in today. First one bounced a couple times but the next three were dead on. Really starting to enjoy this plane

                    I just joined the Corsair Family. Bought the Birdcage. Where do you all place your RX? I think I heard not to place RXs close to carbon fiber. Is it ok to place it next to the blue box? Also, do you all use the blue box?

                              Maiden flight and crash yesterday :( Tough posting videos of pilot error, but if it saves anyone else... I am not a very good pilot, but have improved a ton with my E-Flite P-51 and A-10 and micro A10. I have intercut hat cam and on board cam. I think I didnt carry enough speed and she stalls right near the end (you can see the nose drop) and bounces like a basketball. I believe I was used to my smaller P-51 and her landing speed. I had mid flaps down. Full flaps I may have been ok. I wish I did some more practice runs and practice stalls to learn the plane's characteristics before bringing her down the first time. Damage was relatively minor... landing gear and prop. Parts arrive Wednesday and I will try again. Video is from Brunswick, MD. Flying over railroad tracks, C&O Canal and looking at Virginia across the Potomac River. I live near Harper's Ferry, WV.

                              Any suggestions, tips or corrections on landing would be great. It happened pretty quick.

                                I'd say fly it down keep the throttle up just enough for it to keep a slow sink, use the throttle to adjust the sink rate use the elevator to keep the plane flat, as you are about to touch down (like 1-2 feet off the deck) chop power and flare lightly to keep the sink rate stable. On touch down keep adding elevator slowly as to not induce a bounce. That's the best way I can explain how I land my warbirds.

                                  To be honest, i think most of that was good.. but at the last minute u tried too get or slam it down... im not a great pilot,, but around 200 on this corsair.. have learned alot, mostly from the fine people on this thread.. so what i say is when u r that close to the ground dont force it,, it was still flying nicely and if let go
                                  (no down elev) at that last bit,, it would have been a way better outcome,, but a little further down the runway... short Answer is let it settle on its own last 50 feet or so.. i have not broken gear with this method. Happy flying

                                    f4u ausie.. I think you helped point out the problem... I don't think I ever touched the elevator, she fell :( I bet full down flaps and it would have been ok or more speed and using more runway.

                                    Thanks rifleman, I am going to fire up the simulator and work on your method!

                                      Another possible landing technique with the Corsair (and in fact I use it on the 1600mm Spitfire and 1700mm Mustang), is to land with full flaps and reduce power once lined up with the runway to 38% throttle and fly it down to the runway leveling off about 1-2 feet off the deck, then reduce throttle to 25% and keep it level till the mains touch. My main wheels are on the deck with the throttle still at 25%. After touch down, then slowly reduce throttle to 0. For me, this ends up with a very smooth and scale landing and since doing it this way, I've yet to damaged the retracts in any way after over 100 flights. First 15 flights I went through at least 6 retracts trying to flop it in, chop power or even do a three point landing. These retracts just don't hold up to that. The Spitfire and Mustang I use slightly less throttle, 28%, then 18%. Just another way to "skin the cat".

                                        Awesome, thanks my guy! Appreciate all the help fellas! My replacement retracts arrive tomorrow and I am excited to try again. Will continue to work with RF 9.5. There is a 1600mm Corsair available for it... it includes fragile landing gear as well :)

                                          Hey All, I have made some progress. Assembly of the fwd turtle-deck is completed and the canopy bow and canopy are now one piece which lets me start on the fwd cockpit IP and shroud again. I am inspired to see parts become assemblies finally. Tamms asked me this morning, "when are you going to finish your plane?" I damn near spit coffee! Well, at least she's interested... Best, LB
