Wayne (and company  ;D ),

No, some kind of contamination. I kept getting fish eye, then when I overcame that, got puckering. Really weird. But, as I am the inventive sort and never afraid of a challenge. I just stripped the whole area, put down new fillet material, sanded, cleaned the crap out of it and shot paint on it yesterday. Whatever monsterous demon was there is now exorcised and the whole plane is white and ready for trim.

What an enormous pain. But as Mark Scarborough says, the best finishers are the ones that can overcome issues.  This base is far from perfect and if I had the patience, I would sand the whole thing down with 600 wet, reshoot and make it perfect. But as it turns out, I don't have the patience and I don't want it to weigh 80oz when done. Shouldn't look too bad and has the chance of being done for VSC. Maybe.

 Good luck from here on out, and get those VSC reservations made!

 And yeah that reminds me, I haven't "seen" Mark around here for awhile.

Mark's hanging out in Libby, Montana. Poor him.

Meanwhile, I plan to send in my reservation for the banquet and contest next month. My housing for the week is taken care of.

And since I finally go base color done (though it will now need some touch up due to tape pulling up paint bits - sigh), I got most of the paint on the fuse. Still some black and some stuff on the bottom to put on, but here it is so far.

Hey Wayne,

Sorry, I was off on vacation for the last 12 days. Just got back. I will continue on this weekend. Getting close. Trying to decide how much in the way of inklines I want to invest. Worth didn't use many.

Yes, it's done and on it's way to VSC with the wonderful Pete Peterson. I will follow next Sunday. Yippee. And here are the final pics. I haven't flown it yet (another year with an untested plane) but I suspect it will be a model toad.

I hope it flies as well or better than it looks.  That is gorgeous.   Maybe Pete will test fly it and trim it out for you. LL~ LL~  Wish I could be there. :(

Howard,

Well, unfortunately, like most of my trips to VSC. The plan is already gone with Pete to Tucson. I didn't get it done till about a minute before Pete left. I would love to come out to Stonehenge to fly after VSC. I look forward to it.

Brief update. The plane has flown and I hooked up the lines correctly and everything. 2, 2 minute flights to insure that nothing awful happened and one full pattern. It issues but strangely, not the ones I thought it would have. I think it will ultimately all be correctable. For VSC, it should be relatively OK.  Fully correctable when I can get it home. Cool plane, overall. Looks wicked in the air.

I would say he did good with a 24th out of 36 entries.  Especially since the plane had first flights at VSC.  Now Randy when you give up on it the old DOC is here to take it off your hands. LL~ LL~

Just a note. I have some serious issues to deal with with the plane, but correctable. That's something. It did win the I-Beam award, so that's something.

You deserved it Randy. Your plane is incredible. Chris and I studied it for a while. I think I picked up some neat things you did around the cowl and cockpit area I'll try to incorporate in my stuka build.

 Sounds good Randy, hopefully you can work out whatever little bugs you feel it has and then fly the heck out of this one. Congrats on the Beamer award too, I'm sure it was well deserved.

 I'm already wondering what's next on the build list...  :)

Wayne,

It will be fine in the end. Does need some fixes, etc. And the new plan is a deep, dark secret. It's sorta based on a kit. Kinda. Pics will follow in the building thread at some point. The new one will not be real pretty but should fly well.

So, follow up. The original drive train in the plane (E-Flite 32, 75amp ESC and 2800mAh, 5S 30c battery) weighed 23oz. Yea, that's heavy. Had to add 5+oz to the tail and it was still nose heavy. Yikes. Sucker weighed 65oz with battery. Not good. But on the plus side, I had most of 35% of the battery left after a flight.

So, ordered new drive train (Cobra 2826/12 motor, 50amp ESC and 2800mAh, 30c, 4s battery).  New drive train weight: 15.9oz Yea, that's 7.1oz PLUS I lose the 5 and change ounces off the tail.  End up being 12.3oz lighter bringing the overall weight down to about 53oz. That I can live with. Hope the set up has enough juice to drive the plane. Should.

And I found the hangup in the control system. Pretty stupid, too. Figures.

I know that you aren't asking, but is that the correct motor for 4 cells - Kv that you want.  You may be pushed to fit a prop to the kv.  I think that the motor is usually used with 5 cells.

In addition, the 28 series runs hot when in a built up fuse.  See the threads below

https://stunthanger.com/smf/gettin-all-amp'ed-up!/plane-for-cobra-282610-and-12/msg421221/#msg421221

https://stunthanger.com/smf/gettin-all-amp'ed-up!/help-with-motor-overheating!/msg408846/#msg408846

You might find a more favorable kv in the 2826 series, or in the 3515 series with only 7 grams more weight.

Randy, like Fred says, I Think you need a higher Kv rating.  An Eflight power 25 Kv 870 or a Cobra  2826/10 930 Kv will let you get the RPM's you will looking for.

The new (since Dec 2017) Brodak 2826 has a kv=950 (sweet spot for 4S) and is a 3-bearing motor with a doubled bearing at the top of the "tower".   I expect it and the larger 3520 (also 950 kv) will be popular choices in this size range.

So, the 2826/10, 930kv is a better choice it seems. Have a couple of those in the drawer. And the weight is comparable to the 2826/12.

And it's together and test run at least. Plane is now about a pound lighter. Still not a lightweight, but much lighter. Guess we'll see how it goes the weekend.

I managed to get an ugly cold (benefits of working with kids) and didn't go to contest. I did manage to get out to a school yesterday and flew it twice. It's better.
