could this be static

[brin]

put together a t-rex 450s as my first build with help from a good friend
all went well untill we took it to the flying club where we had the help of f some pros to do the maiden flight it was hovering very well i was so excited big smile on my face and suddenly it nosedived to the right
thankfully not to much damage £40-after a rebuild we tried again
this time we noticed the right servo was wagging so it was back to the garrage where i striped the servo to see if there was any gears broken
nothing wrong there flew it in the garden and all seemed well after a few minutes we tried to take off again but there was very little throttle
response thought we had blown the motor but tonight we bench tested the heli without the blades and it spooled up ok could we be having a problem with static interference could anybody throw some light on this for me please

frustrated and ****ed off brin

Mmmmmm, several factors here.

Are you on 35meg or 2.4ghz

Faulty servo although it could be working albeit not correctly.

Double check all your connections.

If on 2.4ghz re-bind the heli to the receiver.

Re-program the esc

i am on 2.4 dx6i with spectrum rx and all connections seem ok but i will double check
i shall give re binding a go but all the servos and motor were responding correctly several hrs later but every thing is worth trying as i am afraid to take it up without knowing what is wrong thanks very much buster

Can't blame you for that brin..

If you are still unsure about its ability to stay in control when trying to fly it then harness it down to a workbench or similar and run a couple of lipos through it working all the servos hard watching they respond correctly.

PS: Safety warning::: Make sure you fasten the heli down real tight if you try this method.

there has been a few videos on youtube about the 450 and 600 showing the amount of static resulting in brown out on the 2.4 would this cause the motor to run very slowly or am i reading to much into this cheers

hi all
maybe getting to closer to resolving some of the problems i've had with my 450s
we have eliminated the static from the main gears and bench tested it to make sure everything was working properly and my mate then had a go flying it in the garden
and what a difference i was soooooooo happy now to get my bmfa and club membership i cant wait i might try hovering it in my garden for now but its only 15mtrs
sq not much room for error is it worth the risk? anyway onward and upward as the say
happier brin

No it is not worth the risk trying to make unskilled first hovers in the garden.
Even if you are a quick learner it will end in disaster.
you need an area about half the size of a tennis court for first hovers (I'm assumeing this is your firstheli). Its pretty easy to keep it level and let it move about a bit and keep putting it down, but more difficult to keep it is an a small space.
Learn to hover it in a big space, put a marker down and learn to keep it close to that - then when you know you are good enough, hover it in your garden.
This was my way, and it got the hovering pretty good and now I can even do pirouettes in my small garden - but I can also fly it over a wall into a field at the back
