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.
Have you done anything with the arms ?

Grease it all if you are having problems including the front hinge. Keep the wires short. Use a 2cell LiPo. You can also disconnect the drive and check the arm for ANY resistance / friction, with the wing panel removed. It should drop freely with no friction. The system relies on resistance for the amp out. This is a very good and reliable way to cut them out, but it can be fooled by other resistance.

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.

These are the control boxes for the wings and gear and the programer.

Here is one of the drive units for our electric canopy. Mitch has changed the way it connects, so I will need to make a change to the sliding structure before I can ship these out to those who are waiting.

Mitch and Ron always send back all the air parts they remove.

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
John Corben

Thank you John. I hear Mars has some beautiful women. Just sayin, anyway, Yes, I will tell Mitch. Spoke to him earlier in the week and he has been trying to get ahaolg of me for the last two days. Phone tag. I'll be talking with him today and pass along your greetings.

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?

ram3500-RCU

My Feedback: (221)

Good question. The answer is yes. The down and Locked conversion comes with new side rails to support the motor. What you have removed is all that Mitch will need to do the conversion. as for what is left in the plane, it will need to be removed, but not saved. I have reached in through the wing saddle area and removed the bolt holding the front of the air cylinder. If you can not get it loose, then just cut it loose from the plywood. The structure it is in serves no purpose for the new gear, but it is necessary for support for the bulk head it is connected to, so if you cut it up, just reinforce what you cut up to get the air parts out.

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!

ram3500-RCU

My Feedback: (221)

I did some research on this with some parts I have on hand and here are the pictures.

This is the structure that holds the tail gear. The air cylinder is in place where it would be left after you remove what you can.

ram3500-RCU

Here is the converted gear retracted. You can see that it takes up less room than the air system. I thought that maybe you could leave the air cylinder in the plane.

ram3500-RCU

My Feedback: (221)

However, when you retract the system, the jack screw hits the cylinder before it is fully retracted, with the gear bolted tight against the bulkhead.

ram3500-RCU

My Feedback: (221)

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.

ram3500-RCU

My Feedback: (221)

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.

I was talking to Mitch yesterday and he mentioned another good idea for getting the air cylinder out. Simply drill a small hole on each side to get a nut driver in on the retaining bolt. Easily patched and very simple.

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.

DiscoWings

My Feedback: (76)

One a side note, this is a stupid way to setup the plane, not be able to get to the tail in case you need to service the retract.

ram3500-RCU

My Feedback: (221)

I understand your concerns. It will be fine. We have a Meister P-47 that we retro-converted to electric. On that airplane, it is almost impossible to get the tail gear out after it is built. We converted the mains and left the air on the tail. We had also connected the tail gear doors to the tail strut with linkage, so no air was needed on the doors. Still, the programing was a little tricky. As it turned out, the tail gear wound up on the same timing with the main gear doors in the sequencer. Not really a problem in the air.
