I will try the grease and see what happens.
Have you done anything with the arms ?

You seem to have this system working really well, I have not had any success with the Down And Locked wing conversion. I have sent the units back 4 times and still no joy. Both wings stall on the the way up. I have checked for binding and it seems free. My wings only have Hi tec servos no lights ect so are standard weight.
I will try the grease and see what happens.

So, first check the travel with no jack screw or wing panel. If you feel any sticking or hanging up, dress the contact areas. After you feel no resistance on the full travel, reassemble using a good grease, including the front hinges. Next is the system. Batteries and control box in the wing with short connections. Use 7.4V batteries.
Down & Locked has addressed the tranny issues. Those problems are behind us now, thanks to American know how. The Chinese were either unwilling or not capable of solving those problems.
Please let us know how things work out.

Gear and wing parts just back from Down and Locked for electric conversion. These are parts for Dennis.
tail gear main gear wing arms stop Mitch welds on
The wing arms now come with the 10-32 jack screws, an upgrade from the original 8-32 screws that would flex and bend if jolted.

Hi Gary, Just posting back. Thanks for getting back so quickly. Incidentally I live in Australia and it's a little like living on Mars. Even though Mitch and Ron have been great to deal with, a friend suggested that I look at your web page. I will do as you suggested and see how it goes.Thanks very much, say Hi to Mitch and Ron for when you are speaking to them next.
Regards

I have sent many of my Corsair parts and accessories to Australia. You must have several of these CARF Corsair in country.
Hope you enjoy the thread and that it makes your experience with this airplane even more fun.

Just looked. i have parts going to the US, France, Germany, UK, and Norway. These Corsair get around. Brings us together. Cool.
Sad thing is, all these folks do very well with English and I wouldn't have a clue how to communicate to them in, say, German. I have so much admiration for people who are multi lingual.
Maybe that is why I like pictures so much.

Gary, I think there is something in the American DNA that keeps us from learning other languages.........
Your planes are just fantastic......... Keep the pictures coming........

I am asked every so often about Solo Props and the availability. I decided to look up the new owner and see how things are going. Here is a link to the new Solo Prop. New owner is Patrick Wallace. I have been in communication with him and was impressed with how fast he got back to me and the level of his commitment to fill our needs. very promising. I think we are back in business with our Corsair props.

Guys,
is it possible to remove the tailwheel assembly in its entirety once installed? I'm thinking about going the down and locked route but I can't get the entire tail assembly out, I took out the main bracket, but the air cylinder remains in the fuse, I don't see any way to get it out aside from cutting open the fuse form its sides.
I didn't built my plane so I'm not sure what my options are. How can you get the air cylinder assembly out of the tail?

Here is a picture of the converted gear.

Hrmph...
I wasn't able to reach it out, I think I"m going to go with a hodge podge system, the main will be electric and the gear doors and tail will be air driven. It will be interesting!

A solution to this that would allow you to leave the air cylinder in the plane, and still use the conversion is this. Grind 1/8" off the jack screw (you have this to spare), as you can see in the picture, and install 1/8" washers between the gear and the bulkhead. This will give the jack screw just enough room to retract the gear. I would also get some glue on the cylinder and glue it to the ply support it falls against as it hangs down after being freed from the gear.
A second solution is to simply break out the cylinder and add reinforcement to the structure if needed. I think this can be done through the gear bay.

If you do this, and use my spring loaded gear door system on the tail, which has proved to be very reliable in action, you will need no air in the fuselage. Only air in the wing for the main gear doors, which will then be a closed system with no disconnects.
It may require a slight adjustment in the opening of the gear doors for the tail wheel. Should be minor if at all.
I took the time to look into this because I know there are many Corsairs out there with original gear that would be candidates for the conversion. Hope it helps.

nooo.... I'm not doing that, to a pro builder this is probably cake, to a novice this is a nightmare. I won't be able to match the paint, even thought I have an airbrush and everything. So for me, electric mains and air tail. My main concerns are the mains not locking so this should solve that problem for landings and take offs, the tail doesn't have the same weight and from what I have read people are not having issues with the tail gear failing.
