i had 25 flights in this heli in this flight i fixed a keychain camera and tried flying. it started to pitch front when i take off i couldn't control it and crashed i don't know what caused the crash. i am fixing it, waiting for some spares. :) http://www.youtube.com/watch?v=NqULsXZ05AI (http://www.youtube.com/watch?v=NqULsXZ05AI) Title: Re: 450 fbl heli crash Post by: dhruvafreak on December 20, 2013, 12:45:54 AM I feel its that Receiver issue or a lose connection . :-\
I had problem with that rx many times due to improper placement of antenna . Title: Re: 450 fbl heli crash Post by: dineashkumar on December 20, 2013, 12:51:48 AM i am using rcb 7x
and in rx before this flight i tied both the antennas together and flying in this i separated both and fixed in opposite direction but it crashed :( Title: Re: 450 fbl heli crash Post by: dhruvafreak on December 20, 2013, 01:02:53 AM I Don't have much idea . Do check the instruction by rcbazaar or any other fellow member.

:) Title: Re: 450 fbl heli crash Post by: avesh on December 20, 2013, 11:49:51 AM there could be many reasons,
1. Either of your servo wire went loose. Yesterday i faced similar issue with my rudder, when inspected turned out to be a loose wire. 2. Press the master/slave button on the receiver, which would enable slave circuit. 3. Might be one of your servo misfired.

dinesh please dont use that woodies on you fbl, they are not perfect for so. Get a fiber one and where did you mount the camera, i hope it was not on the canopy.. too shaky :) Title: Re: 450 fbl heli crash Post by: dineashkumar on December 20, 2013, 11:19:24 PM i checked after the crash but nothing was loose and servos worked fine,
could be rx problem. i will check that. cg is good as its weight is negligible thanks avesh i will replace it with cf blades and i mounted the camera under the canopy. camera was attached to the canopy. thanks avesh & kumar :) |
