RC Scale Roban 470 AH-1 Cobra Part 2/ Killer Cobra Strikes Again!!!

After the end of the last video, I was determined to try once more to get this little pain in the ass model helicopter to fly.
I tried a new approach on what might make it happen, but as you will see…….we’ll just watch guys.

You gave it your all friend, just a badly design fuselage. I've watched a lot of builders and consider you one of the best👍

[@TheRMRCchannel]

Wow, thanks

[@jamesstratton5061]

Got the same problem with my 700 Roban. Everything is balanced but the tail shakes like hell. Found the the torque tube was 3 grams heavier on one side of the tube on my balancer. Ordered another torque tube and it arrived bent. Went to order another and now there out of stock. 😂

[@dogtrpp]

Thanks for putting out the videos, really enjoy your content.

[@TheRMRCchannel]

Glad you like them!

[@bladerunner469]

I will agree is something you really have to work with I got mines in the air and was able to maintain it I have two videos on here both of them are with a four bladed head

Its like Christmas when I see a new video. I have a Roban 700 EC665 and never had this issue. It seems the fiberglass is weak in the upper par when you wiggled it while mechs were in fuselage. Cant you expoxy carbon fiber weave to the fuselage going back of the turbine exhaust and on the sides and top? Also you can get resonance in the skids..where it looked like it originated. Sorry

[@Aberamentho2010]

Yeah, I would scrap it. Some helis are just seemed destined to be nothing but a money pit and give you pure frustration. Definitely Time to move on.

[@hanspetervonderfecht7722]

Looks like the blades have sucked in the canopy. You did nothing wrong. Its a miss construction for me.

[@majorsmackdown]

Brother - I feel your pain !! (probably not exactly to the same degree as you though)

[@richardbrown9035]

And add a 500 size servo for the tail holds much better

[@JoBarnes816]

It's a shame, so much work🤐. Anyway, Merry Christmas and a Happy New Year from Germany.👍

[@TheRMRCchannel]

Thank you Happy Christmas to you too

[@rchelicopter]

I feel for you man. It's never seemed right, just a horrible airframe.

[@allTheSixes66]

Just one of those things Rob when nothing will work, with your patience I'm sure you would come to it another day & have it sorted... But prob time to move on like you say

[@TheRMRCchannel]

We’ll see, I may return to it one day

[@shaundavies5151]

Wow I had the same problem with a Roban Airwolf :(((

[@binauchich]

It is not stiff enough at all. Normaly u have these sidewalls which make it stiff. It must vibrate. With the higher head speed u just come out of the resonance frequenz

[@TheRMRCchannel]

The fuselage is made of thick fibreglass, it’s not flimsy

[@richardbrown9035]

Adjust the dials on the ar7210bx can't remember which one u need to adjust??

[@TheRMRCchannel]

It’s a dead deal now pal, not doing anything with it anymore

[@richardbrown9035]

@@TheRMRCchannel oh oh whys that buddy I can't remember which pot it was look on the manual I think it was number 1 pot and adjust clock wire.

[@billstanley5945]

Not good when you have issues like that. I’m thinking the issue you were having was caused by the way gram was mounted in the fuselage. Not rigid enough I know you said you were going to scrap it but why not build a whole new frame and mounting system? And use all align mechanics. That’s what I would do, It’s a nice looking heli and would love to see you have sone success with it.

[@TheRMRCchannel]

Trouble is it’s a narrow fuselage and Align do not make any small main gears that would fit where the gears go, but not gonna lie I have thought about making my own set of mechanics up for it

[@billstanley5945]

@@TheRMRCchannel yeah maybe get a gear 3D printed. Similar to what is there now but stronger

[@very9000]

Hello. Tell me, what was the problem with the helicopter?

[@TheRMRCchannel]

If I knew that I would of been able to fix it. Just a bad design

[@Dhouston1125]

sea harrier is a dead project?

[@TheRMRCchannel]

Yep for now

[@joseriverjr6720]

To much head speed create resonance.. hapens to me one time i learn the hard way .. head speed had to be 1700 rpm
