[NSRCA-discussion] OS 140RX Need Help (Final update)

[Lisa n Larry]

“I'll see if it makes it through the first 1 1/2 snap...”

 

I sure hope it holds together, it will become very interesting fast


 

Yep, it folded right behind the wing. It is still together, but buckled in
on the side


 

I believe I can get it set in a jig then cut out any wrinkle that keeps it
from pulling straight and put a dummy plate on the outside. I need to get a
cross hair laser that Dean Funk had on his build thread. Then I can start
with thin coat of micro-balloons and epoxy mix to make the outside sandable.
After that, epoxy in CF cloth on the inside for strength and an attempt to
keep it light
Do this wherever it’s wrinkled and I think I can make it
flyable again
It will probably cost me a few ounces, but I might be able to
keep it under 11 pounds


 

Probably a good project for me to get my building skills up before putting
together a BMVF3
I’ll benefit from learning to paint as well
LOL

 

Thanks Ken, there is a bright side to every problem
My biggest challenge is
being a perfectionist. How do I keep everything within 1/32nd of an inch
now
? Vbg

Very sorry to hear about your bird...I too had an issue with my Genesis...my
motor fried at a very bad spot...couldn't quite make it back to the good
part of the runway, had to set it down in the tall weeds...folded gear plate
and just noticed a wrinkle in the right side of the fuse at the trailing
edge of the wing position...it's repaired somewhat, I'll see if it makes it
throught the first 1 1/2 snap...

Got to the flying field and charged everything up


 

Started the 140RX and tons of power running very smooth. Lisa took the
Temptation out to the runway, one more run up to clear the engine


 

Take off was beautiful, very smooth at ½ throttle and very nice climb out to
about 20’ and bank to the left for a easy 180 degree turn down wind


 

Leveled wings and was about 100’ and added power
No power, now a glider
.it
was a tight rope staying just above stall to land easy in the tall weeds


 

I observed the tip stall about 2 feet above earth, and yep it’s a composite
fuse
you know where it folded. That was the only damage
Repairable to some,
not sure I want the task


 

I have no idea why the engine quit and will probably never know at this
point


 

As for my weekend, this was the second plane in two days that were
sacrificed to the RC Plane Gods if you will
Lisa’s trainer met it’s demise
yesterday while my dad was on the buddy box. He got into trouble and I took
back control at about 50’ with no problem. Well until I pulled elevator to
gain altitude. I observed a narrow blue covering that I couldn’t place right
before she headed to earth at full throttle. My thumbs were in the low left
corner on the right stick and full up on the left stick. I held it in that
position to verify what happened


 

The blue line was the only blue on the plane
The leading edge of the wing.
Normally not a bad observation if the plane is coming toward you, however,
it was going away from me. The wing left the plane when I pulled
elevator
The wing first lifted on the left appearing to bank sharp to the
right
What I saw verified my final stick positions


 

I’ve only lost one other plane since 85’
I guess we all pay up sometime or
another


 

Not sure what I will do from here, but we will not be making Quincy, OH
