    So I maidened the Sbach this morning and it flew great, I had to trim just a tad and was on a roll till I hit my switch that deactivated my throttle which was telling me to go to work.


    Later at lunch time I took it behind my building and managed to have an aerial landing in a tree which I spent the rest of the day getting it out.

    Definitely worth the build.

    It looked like you had a good feel for it already. ..nice fly.

    We can always put a little tape over that switch for you.

    You're a very smooth flyer, flyinghigh! And its great you have a place to fly during lunch. Too bad about the tree. That's a great paint scheme, hope it didn't get ruined!

    Some what maidend mine today,it was calm at the house but by the time i got to the only space i could fly the breeze picked up but got it up any way,"Giggidy". But i was to nervous flying over pavement in the wind so brought it back down only loosing a prop and side genurater which was a clean break.Im going to have to waite untill the corn comes down to fly any thing.:(

    Sounds like you made a good effort though. Most any profile in a gusty wind can be a real handful to keep on track.

    Fortunately damage is light and you're good yet to fly another day.

    It was going pretty good, i was happy even though it was a short flight.I had an 800 Mah 2 cell in it witch gave her plenty of energy,but these planes really don't like pavement and it seems to act like a magnet.

    Too bad the wind kicked up! You're right, these types of planes are really useless when the wind kicks up. Gidget is a reference most guys on this forum won't know unless they look it up!

    Here is my tree landing. I realize I was higher than I thought and was paying more attention to what I was doing than the tree I was near.

    I was able to repair it but it put another ounce on it. I will definitely build another as it was so much fun.

    Reminder to self, stay close and low.

    Haha, like the ending. Of the video, I mean. Not the tree part, but the Wheel of fortune part. Looked good until then!

    couple more pics of mine nearing completion..only had a short time to work on it each day...

    the combo of EPP and depron is an interesting one...really may not be the best!

    here is a pic of the wings glued to the horizontal fuselage piece..

    IMG_20150918_102917784_HDR.jpg

    i added a piece of ply to brace the connection point...it flexed too much...

    IMG_20150918_104025175_HDR.jpg

    you wanna see me FLEX?????? LOL

    IMG_20150918_104612728_HDR.jpg

    Once i put the vertical fuselage piece on it didn't flex vertically....but....the tail would rotate in a big arc just by moving it around....so i had to brace it....some very lightweight balsa stringers were glued in..and then used square cut hobby sticks (Popsicle sticks) to tie in the elevator.....it works for now...

    IMG_20150921_101619882_HDR.jpg

    here it is nearing the main build completion...

    IMG_20150921_170848937.jpg

    and my stopping point yesterday....all electronics are in....will have to swap out the ESC...one i have in there is acting like it is on a heli program..soft startup and then a ramp up of power...

    IMG_20150922_161610806_HDR.jpg

    but..as i feared combining EPP and Depron..this is heavy...i haven't weighed it..but without a battery it is over a pound for sure....this will not be a super slow speed floater like others i've seen on here....i'm worried about the tail flex as well...we'll see i guess....may try for a quick maiden later this week just to see if it even flies!

    Let's see how it goes, Dan, it floats like a butterfly at 12 oz, so maybe it'll be ok. I've got 9mm high density epp left from the alpha jet so maybe I'll try this too. If yours flies, that is

    It's good to have you back in the hunt Dan.

    I'm taking notes btw...to carry over into the 80% epp indoor sbach.

    I need to figure out a super lightweight solution to EPP bracing...it is good stuff...just gets heavy when you try to eliminate the flex...
