Title: Well, there goes the SV-11.....
Post by: JohnPrator on April 16, 2011, 05:00:55 PM
Ok I cannot believe this one. My new SV-11 lasted exactly 4.5 flights.  :'( On the 5th flight I was just lazily poking around and being extra safe as I was still a little "gun shy" over the Vector incident when the crimp on my Bob Morris handle(that I bought preassembled!) let go on the up line! This is VERY frustrating, even though it was an ARF it still took me quite some time to get this one put together the way I wanted it; excellent motor install, arming switch, beautiful wiring job and I installed the ESC in the wing saddle with some great cooling duct work too! I'm trying really hard here but it sure seems that if it weren't for bad luck I'd have no luck at all. There goes another $200.... ''

My wife caught it on video(of course) if you'd like to see it happen;

Looks like it was flying pretty good too!! It does look fixable. Did you damage the motor or battery? I always run my own cables though my handles because that's exactly what I don't want to happen to me. I also change them often too. If you do fix it go over it carefully to make sure there is no hidden damage.

Wow!!!!!! I sure hope you get an apology and a full refund for that handle.

Really sorry to see that... you've been trying so hard and doing so well too!  Keep it up mate, don't give up! 

Get into the habit of doing pull tests!

dammit-dammit-DAMMIT!  The bird was really flying well.  What a frustrating way for it to end. 

It looks like the wing and stab could be salvageable.  I hope you can rebuild - or at least build a new fuse for the wing & tail.  Or call up Brodak and see if they can sell you a new fuse.

that SUCKS!!!!!


keep at it tho - dont let it beat ya!.

As Warren said - get into the habit of doing a pull test before you fly - it is something that we dont do often enough on "practise" days - it may have saved you on this one.....

John,

For what it is worth and in this case it is too late so not worth anything. This happened to me (many many years ago) when I was a kid. I found that if you let the remaining line go a bit slack during the climbing phase of the loops, you can control the altitude of the loop. If you can keep it flying until the motor stops, you have a chance of minimizing the damage when it does finally hit the ground.  y1
Of course you didn't have time to adjust in this case but maybe next time (hope there never is a next time!!!).  :!

I think he said the up line let loose - goes splat in 1/2 second   ~^

I appreciate everyone's comments/help, hopefully I can get another one in the air soon as I'd really like to get more flying time rather than crashing time someday soon...

I noticed in the video if you watch it closely right about the 1:27 mark the plane bobbles downward for just a second. Then at about 1:30 on the third inside "loop" I remember that it seemed to almost slip/straighten out for a second, you can see this at the top of the third "loop". Finally at 1:56 the line slips out of the crimp. I'm wondering if those subtle little signs above at 1:27 and 1:30 were the line slipping in the crimp just a little at a time?

Thanks to all of you for the support, much appreciated. I have been trying hard and it seems Mr Murphy has been by my side the entire time, but, I'm not going to give up. If you notice I was flying very carefully, not doing anything risky, staying far away from Mother Earth yet still broke yet another plane. I am frustrated, no doubt about that, but I'll still keep trying. Luckily I have an ARF P-40 so I think I'm going to put it together and I will double check everything I can think of. I'm a Spear Fisherman so I have all the goodies to redo all the cables in that handle the correct way. If my setups can hold a pissed off 50 pound Amber Jack it can hold these planes-I hope!  ;D

PS-Ya gotta love my wife's talking to herself(needing to got to the bathroom etc.) and then giggling about me wadding up another one! She just seems to think this is hilarious... ''

Personally I have never trusted a crimp connection.  I wrap my own lines - have never had one turn loose. My Extra 300S (10# with a 120 4C for power) pulls like a bear at full throttle. You have to put you back into it to keep it under controll.  I use the Tom More hard point Handel with safety nuts added to the I-bolts.

I lliked your wife's comments! Giving input to the trim of the plane that it needs more tip weight. Man, that is getting into it! And she doesn't shake shake the camera with the crash to boot! Doesn't get much better than that in my opinion!

She's a riot and thinks it's funny when I wad one up. She's used to seeing it happen too, that girl has seen me break more airplanes and helicopters than you can imagine. I was taught to fly heli's by a famous heli pilot by the name of Curtis Youngblood back when he was in college and she used to just sit back and giggle at him getting frustrated at me and my antics. Man that boy sure could fly...

I've always thought those electric engines had too much power.

It looks repairable. - could have been ALOT worse.

I think I would go to hard point handles. two less crimps to worry about

Two tail booms , and youkll have youself a Vampire Jet .
 Mk 1s had Square fins.Plastic cover for nose ?or foam .

If the wings O.K.

Theres shut of thingos for those motors that shutem down if the prop hits
your finger or other things. Looks like the last loop was a carrier launch .

Two nails in a fence and see if you can break the lines teaches you a few things.
They dont have to be on the model , .018 takes a fair haul to get it stretching .

Ive had twangs of stretch in bottoms of loops or Square loops in 20 Knot wind
with a 2 kilo plane . Regard it a bit like steer wrestling at times.
Maintain the initiative , a bit like staying ahead of those fish .
