    It's a beautifully executed build of a clever and historic model. I was jealous of the fit and finish when I saw it.

    She is a beauty for sure! I keep both a 'Long List' and a 'Short List' of projects I want to work on, and completing this lady through a maiden flight is on the short list. Right after the half-built Balsa Cuda occupying my workbench, and repairs from FFE

    Aw shucks PsyBorg, the honor and privilege were all mine. I would do it all again in a heartbeat, next week if I could. Everything about Flite Fest was a huge enjoyment. And you sir are now not only a shipmate but a dear friend. Thanks for keeping me company on the ride and to you Rocky, and Litterbug for the company at camp. And thanks for pushing me into real heli flying. I hope I can manage it.

    Now to plan for next year...

    Psyborg's Caudron is back on the workbench!

    Finished painting, hinging and connecting the ailerons last night, hinged the top hatch, and installed the rudder pull-pull control horns.

    The to do list is pretty short on this baby now;

    - Finish hooking up the rudder control rods.
    - Hook up the elevator control horns and rods. This one will be a touch tricky as the two rods are hooked into different holes on the servo arm. This means that one of the rods actually travels a little bit more than the other. And that servo is installed really solidly - not pulling it back out now So plan A is to make the control horn for one of the elevator sides longer by the difference in the space between the rods at the servo end. It makes sense in my head anyway, I'll see if it works soon.
    - Install battery tray
    - Install prop & spinner (which I seem to have lost in the shop somewhere....)
    - Final balancing & binding

    Now that you had some time to poke and prod it whats the verdict? Ya think its good enough to fly or will it just be a pretty lawn dart? Oh yeah and I found the other props I meant to send with it but they were hiding on a shelf here and I did not grab them. I can send them out to you as well. Like I said in the FW thread.. gimme a good time to call or ring me up and we can work the details out.

    Oh and btw.. When I put the servos in I worked them back and forth and I believe there is already offset on the servo horns inside. Maybe put some marks on the wires and work the servos so you can measure travel. I did think about that when I put them in before covering them. Whether I did it correctly well... Also if it is too far off there is always the option to clip one of the rods and make it a single sided set up. That is why I did not close the bottom up yet and I sent the plate and the textured paint for the belly with you.

    And now I am nervous as all I can picture is it getting launched, the fuse filling with air pressure and the whole thing swelling up and exploding in mid air.

    Oh and one more thing I just remembered. I did the motor so it has adjustable thrust angle (which will probably be a huge pain to adjust now that its all together) but I did not however offset the mounting position to accommodate keeping the motor centered once the thrust angle has been set. It is however set higher then the original design as that was discussed during the flight testing to mount it higher. HOPEFULLY that does not throw the pull to far off center line and give it really bad tendencies. Sorry I was not aware that was a necessity at the point I was working it all out.

    I'm sure she will be able to fly. I am way less sure of my ability as a pilot to land her properly.

    No need to send me the props - I've got a whole mess of different sizes from various online sales. What size was on that motor originally?

    I'm pretty sure the elevator horns will work out - I made up the set last night and gave them a coat of paint. Plan to install them tonight. Finished up the rudder controls last night - works perfectly smooth and stable, no wiggly bits! And there is plenty of venting at the back - I'll make sure she doesn't act like a weather balloon.

    The higher motor thrust line looks great - just like my final big blue one. I did notice the thrust angle was a little strong for my taste, and I'm glad to hear it's an adjustable mount. I've got a small inspection mirror I can use to see how to adjust it - hopefully without tearing anything apart

    The motor mount is long bolts loctited into metal stand offs so they dont spin. (Still accessible I believe from the under carriage if the main wing is off) Then nylocks on either side of the motor mount. Small crows foot wrench would be perfect but I did it with a straight wrench. You may have to remove the motor to get to the back ones with the nose glued on OR you could eyeball the alignment and cut slots in the top to allow for wrench access without doing too much work. This is what I thought I might have to do after permanently attaching that top section anyways.

    Looks like I would need to cut her open to adjust the thrust angle... and it just might be an elective procedure, so I'm going to leave her with this angle for maiden.

    The one prop collet I have in the drawer that fits this motor shaft won't tighten up with the spinner installed. So she'll be a little exposed till I figure out what type of spinner/prop mount I need to get for her.

    So all that's left now is the battery tray and balancing

    Might even get her out to the field this weekend if it dries out down here....

    Wow did you clear coat that too? or just buff n wax it? It looks much shinier in your pictures. Once that has been tested and maidened a cockpit would complete it. I started to design it and I think I left you the pattern and the blueberry package lid to cut it from didn't I?
    No biggie without it as long as it flys for you I will be very happy and glad you took time to finish it up.

    Did you go with my idea to line the aileron cutouts in balsa or did you do something different?

    Oh yeah forgot to answer you about original prop for that motor when it was on the Pitts.. manual says 13x6 and I sent all the ones I had with you for that. The speed controller is a 50 amp in case you cant dig in and see in case you want to run numbers for different props. The motor is BM3720A-KV650 and I believe they are

    Good to see people are still playing with these race birds. My Folkerts is sitting forlornly in a corner hoping to fly again someday. I think my wife would be really happy if I never ever flew it again though!
