Talking GWS F4U Corsair maidened

Hi guys,

This RC thing has really caught me BUT it sure is fun! Yesterday I bought a Corsair, which is one of my favourite ww2 planes.

The building phase took me 12 hours. I finished the paint job this morning and maidened it in the evening eventhough it was raining a bit. A quick 2 minute flight and tried few basic manouveres, rolls and loops. The elevator was too sensitive for my taste, so I reduced the EPA and increased EXP. Also the plane wanted to go up all the time so I trimmed it down, but I have to change the motors angle of attack later tomorrow.

About the performance. I have a 3s 1800 mah lipo and turnigy 28-30-azj brushless with an APC 9x4,5 prop and I got unlimited vertical power with 3/4 throttle. The beaver, which I had eariler, could barely hover with full power

Few cons,though, The battery compartment is very small I had to carve it also the battery cover magnets are weak, won't hold in stress.

Nice job on the Corsair I had one of those too, it needs about 3 to 5 degrees of down thrust, that will fix the wanting to go up under power, just add some washers to the top of the motor mount, to shim it down, you may have noticed that the landing gear wires are very weak and want to bend and wobble on take off, I used some CF tube, slit it leangth wise, sliped it over the wire, and CA it on, that helped a lot, now I was able to take off take care and have fun, Chellie.

Yep, noticed the landing gear. I took mine of since I'm a belly lander

I used one of these for a motor mount http://www.rinotop.fi/raudoitus/x2108.jpg . They are a perfect fit for the motor. Just drill holes for 4 screws and add washers.

Those are the plastic platforms used by steel fixers to get the steel bars on right elevation. Reference picture in thumbnails. I took a handfull of those from my construction yard.

They really are a gentle flyer - pretty good for a first warbird. They are not very powerfull with the GWS motors, but put in a park 450 and things get pretty interesting!

Here is mine:
