Re maiden didnt go so well
Finished the build with new scorpion and ikon. Got it up into a hover, everything looked good, then the ikon shut down. Crash wasn't too bad. Just blades and tail hub. Wanted to get the cyclones anyway so ordered those and new hub. Problem is, I have no idea what happened. After the crash, there were no lights on the ikon and no power to servos but it was obviously still getting power because the satellites were still on with a solid orange light on both. After I cycled the power, everything worked fine. Been trying to recreate the problem spooling on the bench but no luck. I'm thinking maybe a bad solder joint that doesn't come loose until there's enough vibration from spooling up with the blades. The guy I got the ikon from also bought it used but never flew it. Not sure where to go from here

Things I can think of: OWB, static hit, FBL controller, power failure...

i guess a static hit could be a possibility, but wouldnt it reboot afterwards? it wasnt a power failure because there was still power going to the satellites even after the ikon was shut down. Also not a OWB. when i said ikon shut down, i mean it totally shut down, no control of anything.

EDIT: Maybe try another controller for now and see what happens. Crashes due to electrical/mechanical issues are the most frustrating of all.

yeah, the thing is, i already had it flying perfect with the beastx before i swapped to ikon, so i think that pretty much narrows it down. too bad i traded the beastx off for it. now im out an fbl controller and i dont really want to steal the one off the 6hv or 7hv. i guess im just stuck until i feel like forking out more cash. i will say though, it crashed like a tank, just like my other 2 compass's. it did a nice little chicken dance in my driveway and only lost blades and tail hub.

Ground your boom if it isn't.
If you need another controller I have a trac-x one new in the package sitting on my bench. Otherwise it is possible a static hit can just interrupt function and not cause a total reboot.

Quinn,
Sorry to hear that you had a problem on the test flight, sir. Rob's advice is excellent (as usual): "Ground your boom if it isn't." The boom should be grounded and the belt sprayed with silicon. Static can do anything from sharp control hits, to shutting things down, to frying electronics. As far as FBL controllers go, if you don't go for Rob's TracX, you might look at the Robird (what I have on my 6HV-U and my Stretched Atom). Inexpensive and quite good!

Dude, sorry to hear this! I took it personally when read it. Been following several threads with you for the last few weeks.
I had a mysterious crash back if February and the only things I can blame it on are either a static hit or bad antenna placement. Fixed both and haven't been able to recreate the failure. I'm sure those cyclones will rock!

Also, this time I drilled a screw in my boom to connect the anti-static wire. I also secured the screw with a tie wrap to be sure. Before I just followed the 7HV manual and tie wrapped the exposed end of the anti-static wire to a sanded part of the boom that exposes the aluminum. I am keeping my fingers crossed that the electrical issue I suffered won't rear its ugly head again... especially with the 7HV

Yeah the crash wasnt really a big deal. Really no loss at all since i wanted the new blades anyway. Im just not sure how to go about the ikon situation. I did have my boom grounded, but i never checked continuity and i forgot to spray with silicone. These kind of things are really tricky to make judgement calls with. I guess all i can do is put it all back together, possibly reroute some wiring, make sure ground has continuity, and then run several packs on the bench trying to get it to fail again. if it was my 7hv, i would never risk running this ikon again, but on a heli that only cost a hundred bucks a crash, it might be worth the gamble. The Ikon could be perfectly fine and just took a really bad static hit. I always assumed if it was a case of static, the unit would have powered back on, but maybe it was so bad that it just didnt want to come back on till i cycled power.

Almost ready for the re re maiden. It looks awesome with the cyclones on there. I'm really hoping they give as much pop as the RT's. the cyclones are actually quite a bit narrower up until the last couple inches. I decided to play it safe and for now I'm just gonna borrow the ikon off the 6hv for a while. The cool thing about the atom and 6hv is that they share the same gyro plate so I can actually just take the 4 screws out, unplug servos, and switch the whole plate. I can save the 6hv setup and the atom setup in the computer so all I have to do when I swap back and forth is load the settings and rebind. I also decided to switch to a gryphon bec just to rule out any possibility of what caused the first crash. Since the 6hv and atom share the same packs, I really can't fly both at the same time anyway.

Dude. Reduce your pitch! I was running 14.5* with cyclones and the tail blew out, crashed cyclones on the 2nd flight.

Ok ill start lower. Im hoping since I have enough headroom to govern at 3000, I should have a pretty solid tail at that speed. Did it have pretty crazy pop with the cyclones? Did you run RT's before that?

Yeah, too much pop! I was running edge 473s before with no problem.

Good luck! Take it easy for the first two or three flights.

HOLY CRAP!!! This thing is absolutely insane!! Total success! After a couple flights going easy at 2600 everything looked solid. Tune was actually pretty close for a maiden. Flipped into 3000 (governed) and headspeed didn't even flinch with full collective. It really is a rocket! Like stated before by aburkhardt. Pitch is at 14 for now but it can easily handle more. Tail is totally solid. Hopefully it will still hold when I raise it to 15 degrees. Head gain was a little high at 3000. Little bit of shake on hard cyclic stops. Other than that pretty damn solid. Absolutely locked in fast forward flight at full collective even when pulling hard loops. This thing covers ground like my 7hv! It so insanely fast! I bet this thing could compete well in 500 class speed flying. The cyclones behaved just like the ones on my 7hv. Very snappy and still locked at high speeds. Very happy with the decision I made for the motor (scorpion 4025). Like I suspected, all you get is 3 minutes with 3300's but its a crazy 3 minutes! No big deal since I have 6 packs for it. Pulled a peak of 155 amps on a speed run. Ice 100 took it like a champ. Stayed below 150F and it was about 80 outside. Ill make a few changes in the ikon tonight and also raise pitch to 15 degrees. Very pleased with the results so far!
Edit: all up weight without canopy (how i normally fly) is 2080 grams! And that's still with 6hv skids and fin. Last edited by quinn; 07-18-2014 at 09:09 AM.. |

I can't imagine 3000 headspeed on the 505's, that's insane. 2400 was plenty for me on the stretch.

apparently a little too insane lol. I think i just found the limit of the atom. easily fixable though. today after a couple flights i noticed my gear mesh didnt sound right. Brought it down and both frames were broken between the motor mount and bottom bearing block. I guess the 4025 is making just a bit too much torque with 3000 headspeed and 15 pitch. obviously ill need new frames, but i think ill also reinforce the area by cutting some pieces of carbon to layer on top of the frame in this area. i will extend it to both the motor mount and bottom bearing block and get longer screws to go through both the frame and extra peices of carbon. Should give it enough strength to handle it. It already held up fine for about 50 flight so i think just a little extra support should do the trick.
and before anyone says it, yes im sure i could just lower my pitch or headspeed a bit so the heli could handle it, but whats the fun in that? LOL |
