  I was going to guess that the model sorta resembles an F-5 Freedom Fighter, and I think he did a design called the Freedom, did he not? have to look that one up when I get home.
    Hope Jack is doing well,

Got it fixed. Seems so simple now. The line between hinge pivot and horn pivot had to be 90 degrees to the pushrod to get equal travel in both directions. At the angle the pushrod approached the tail, the horn pivot had to be 1/8 ahead of the elevator hinge to achieve the 90.  I've got 22 degrees on all flippers up and down. Seems like allot of flap, maybe I'll make the elevator horn shorter as I sometimes need to do emergency pull outs. I was going for 1:1 but plans show 1/16th shorter.

Awesome response, Tim - thanks!!  I enjoy folks who can answer a question rather than starting off on tangents about other vaguely related topics.  Nicely done sir !
I have a DigiKey account, so I think I'll go shopping.
Thanks!

ps - attached a zoom of the burnt unit.  Can you make out any recognizable numbers?  Best I can do with a smart-phone camera...

I want to believe that I'm looking at a N-channel MOSFET, but that's not where I would have expected to see the final transistor in the circuit.  If those two leaded components in the foreground are resistors that go to ground over on the right, then it almost certainly is an N-channel, and you can find just about any N-channel MOSFET in a SO-8 package that'll work.

Of course, there's two different widths of SO-8 packages (the thingie marked "2901" in the center of the photo is the bigger size), and I could be wrong about the polarity of the FET.

If you're going to throw it away anyway, and if no one else comes forward with a better idea, then amaze yourself by the selection of 40V N-channel, SO-8 FETs on Digikey (there's probably over 10000 different part numbers to choose from).  Pick one at random, solder it on, and see if the whole thing bursts into flame.

Arrgh!!! I saw that shape at the tailwheel but said nah, he wouldn't plug the access with maple, too heavy he's trying to build light. Never thought it would be a mold. Get back to the build log.

To clear things up Jack uses Shirley's old email address: sasheeks@sbcglobal.net and Shirley uses jssheeks@gmail.com
for her email address.

I will ask Jack Tuesday night to identify the Blue model.
About two weeks ago Jack had 2 more Stents inserted bringing his total to 9.

Tim - Too smoked to read.
I can read the adjacent transistor.  Just hoping someone still has one of these working and can read the numbers on the one that I show as fried.

I have no way of knowing what smoked the transistor.  We use this charger primarily for 3-4 cell packs.  It started giving a "BREAK DOWN" fault which, per the manual, is useless => "There happens the malfunction at the charger circuit by any reason."
We moved it from our deep-cycle battery which was at 12.0V, and put it on our solar-system which was at 12.6 v.  It worked there for a while at 3A, then failed with "BREAK DOWN".
It will occasionally charge up to about 0.3A then bombs out with the same code.  All other functions, menus, etc work fine.

I'm willing to give it one shot - replace the transistor once; if it works - great.  If there's some other failure that causes it to pop again, it goes in the trash.

Thanks Mike. Oh Yes! I remember the shoe polish fuel smell. I think it was in all fuels back then. I ran mostly OK Cub engines with OK fuel in 50 to 52. Couldn't afford the "big engines" I did not know when Duke started manufacturing the 29's, but it must have been shortly after the 35 then since your last one was a 4 bolt head sand cast job.

Excellent summation, Rusty.

Fact: Once the government gets involved, it gets more and more involved (and controlling) until it can choke the life out of the endeavor (and/or subjects) being regulated.

How many more basic freedoms do we want infringed upon?  Haven't we lost enough already?
