Question V911 Replace/Repair Info Needed

Hilly Ho! The tail motor when out on my V911 and the main frame broke. I have the replacement parts, but I don't know how to remove and replace the tail motor, nor do I know how to get the main frame loose and replace it. I was trying to move the tail fin back and in the process broke the main frame. I have main frames with the motor and just the motor. How can I make repairs without breaking the heli? How do you remove and install these parts? Thank you for reading my post.

I think the v911 that the OP is talking about is from WL Toys, not Walkera,

The parts are glued together on the original bird. I had the same problem with mine. You need a really thin and sharp knife to get between the parts. Or just get one main frame, tail boom assembly. You will be set then. Good luck and happy flying.

Arrow Debonder?

Yepper ... I am talking about the WL V911 ... do you think debonder will do the trick? Is the rotor motor glued to the housing too as well as the back fin?

Thanks for posting.

a BnF is $20.... why would you ever replace parts? haha not even worth the trouble. Howd you break it anyways? Ive had mine almost a year and ive hit every hard surface outside at full throttle and ive never replaced a part.

Arrow It was the dog

My dog got a hold of it ... I have the parts to repair it ... and I already have 4 V911's so I don't need to get another BNF ... just want to learn to replace parts so I can when I need too. From what I gather from sdsteve's post is I need to get some glue debonder ... then I will be able to replace the part and have 5 fully functional V911 ... beside ... love to tinker on these helis ... there will come time when they will have to be repaired ... if you can get the parts. Thanks for posting.

Arrow Got her done ...

Well sir ... I got her fixed and flying again ... I got some of that debonder, but it didn't seem to work ... so I just kept cutting and picking until I got all the main frame out of the holder. The replacement part I had was the main frame with the tail rotor already attached. I just soldered the wire together ... left them long from the old rotor so I didn't have to put heat to the PCB. I didn't glue the new main frame because of the hassle getting it loose. Did a flight around the room and it worked great, and looks as good as new.

One of my V911's became a "parts vehicle" yesterday after my rear motor replacement went awry . I popped the rear motor out OK. I put a little hot glue on the back of the replacement motor to protect the wiring and popped the replacement motor back in. I was able to resolder the wires back together Red - Red OK, Black - Blach OK. I coated the wires with liquid electricians' tape with a toothpick OK. It ran . It look kind of funky with those gunked wires hanging off the back. I taped those wires back to the boom frame with electricians' tape. Reinserted battery, fired the heli up... and . Smelled bad too. . It happened real fast. I guess that I did not insulate the wires as well as I thought.

The only good thing that I can report. The driveshaft, rotorhead, and etc. was swapped into my other V911 that was starting to exhibit the TBE and pendulum swing thing which subsequently solved that heli's behavior successfully. I am still flying.

I am also awaiting the delivery of the BNF replacement.
