22inch Wing Span WOT Next finally flies

I posted a week or two ago that I was building a 20" WS WOT NEXT. I had to rebuild it before I even had a chance to test fly it. I had to lower the servo shelf in the fuz to get the RX to fit. I think the re gluing etc added weight, The final AUW was 8.2 OZ. I took it out to the tall weedy area for the maiden flight. I was way under powered with the small 10Gram HK motor. I kept launching the plane and it kept falling out of the sky. I should have given up and finally did when the prop saver flew off never to be seen again. Back to the house to install a dif motor. I chose an Emax 2805 . Back to the weedy test flight site. This time I had enough power, in fact too much as it tended to barrel roll when I opened the throttle. I continued launching and the plane continued falling out of the sky until a wing broke.
Back to the house for repair. I examined the thrust angle and I see instead of having it down and to the right I had it down and to the left WAY left infact: that explained the plane wanting to barrel roll. I corrected that and made a new 22 " wing w/o ailerons . I unplugged the aileron servo and back out to the weedy site I went. ( Getting my exercise) I hand launch again and again and I was not able to control anything. several more launches and several more falling from the sky until I figured out the problem. I was trying to control it with the aileron stick that I had unplugged Moved the rudder to channel 1 or the airleron channel and hand launched and again it fell from the sky. Now what the heck?
I Launched it again the plane goes up and is flying I turn to the left and the plane goes to the right Yep it fell out of the sky Being the "genius" I am, I decided that perhaps the Rudder servo was reversed so checked and sure enough it was, so I reversed the rudder servo and hand launched and FINALLY it flew...........Way to windy to be test flying, as I could just barely go into the wind. I flew it a few times and came back to the house with that long awaited grin on my face. I am quite confident that on a nice still day it will fly quite nicely.
My problems in no way reflect on the fine design of this airplane, They only reflect on me not taking my time before and while building and also being too anxious to test fly. I failed to check servo direction motor thrust etc, definite NO NO's. Oh well now it flies. I am not sure if I will add ailerons or not as it seems to turn fine w/o them

How can a perosn have so many senior moments in such a short time frame?
Persistence pays off again



  WISHING EVERY ONE A HAPPY NEW YEAR

Nice job on the plane, Voyager. Congrats on the eventual success and kudos for hanging in there, too. Of course, no one else has ever made those mistakes. No sir.

Rather than "senior moments" we could call them learner moments - don't need an AARP card to make them. We tend to learn better habits by screwing up and figuring out what went wrong, as you did. Thanks for sharing the experience.

we've all been there. I once inadvertently reversed the throttle channel on my electric Ugly Stick. It wasn't restrained so it just shot across the patch, leaped into the air, executed a big loop and lawn darted into the grass. All this before I had chance to grab the TX.
Prior to my move to 2.4, I once launched a model on the wrong frequency It was something like a 65 crystal in the TX and a 66 in the model. This was just enough to have some control but not enough to have full control if you know what I mean. Took me a minute to realize that it wasn't just interference. Got that drunken model down without damage but the flight wasn't pretty.
It's good the learn from these mistakes on a scratch build. Just think, it could have been a $200 AFTF that you stuffed into the hard unforgiving earth.

"WOT" are great model to build David.
It took me four days to build from start to finish and I have not built a model aircraft for many years. The finished project is very encouraging to me.
It has not been test flown yet and I am waiting for the right wind conditions, to begin the fun. Bring it on!!

Here are a few pics of the build and finished aircraft

I thought I saw or read you put the firewall at zero, so how do you adjust thrust angle on motor?

Just insert a washer or more between the motor mount and firewall. If you need down thrust add the washer/s behind the top mount/s. I find some of the smaller prop inserts useful when I need lots of thrust adjustment

I have finished building my EPP WOT. I have yet to maiden it but the COG seems to be in the right spot, if not just a little forward (which I am perfectly OK with). Waiting on a clear day to get it up in the air. Once I see how it fly's I will put some paint to it.

KFM4 wing, EPP 9mm, CF spar in main wing/horizontal stab/elevator, crappy photo's via iphone .

Headlessagain is indeed correct.. just build it with the firewall square and level and use washers if you feel the need for side or down thrust
both my wot-nexts are quite happy with the motor at zero zero.
