Just finished assembling my hiller 450 pro with all electronics. But was disappointed by the slops present in the grips set. There is also gap between the grip and the O rings. (2-3mm)  . replaced the shaft, O rings, bearings but still no success. Lastly mounted 450 v2 O ring on one grip and the pro one on another  which resulted in absent gap but still the slops are present... Anyways this is the new kit i received from RCB... wt to do

Hey Avesh,

Please post some pictures to show where you see the gap and point the slop if possible.

Thanks

I think the time is ripe for an observation here :

I've noticed a mentality amongst the heli fraternity - to be somewhat "clerical"
by this I mean - over analysis and dependance on the full stops and commas.

Possibly this is a result of the exposure to american forums - where the "Goras" make
things more complicated than they have to. Result - helis are made out as super precision
machines with tighter tolerances than a swiss watch.

Actually - this is only partly true. The ultimate proof of a heli is how it flies - i.e
don't get carried away by all tolerances in mm / pitch curves / throttle curves / super
space age alloys machined cnc etc. , superflous stuff like blade balancers / swash levellers
pitch gauges etc.. None are really required if you have your basic "fundas" correctly.

So get the heli in the air and then see if it flies the way you want - if it does then
nothing else matters.

Hi Saikat,

I think they are super precision machines and thus, need a lot of attention to details.

I would not recommend flying a heli unless you have eliminated most of the slop and are satisfied with the setup.
In this case, the op mentioned slop in the main grips. He is probably missing something like a aluminum collar between grip and damper. So I would definitely not suggest him to try flying the heli in this condition.

Well, all the things you are mentioned are important and building without them can result in more frustration for the user.
Tools are what makes this hobby enjoyable - without them you will be frustrated with questions like why is my heli going right, why is my heli vibrating so much etc

Sorry.. had a busy day....  the slops are not present of both sets but one. Burning the feathering shaft might  ruse it out damn I dont have audacity to get this setup in air.

@Raja sir i have verified my head setup using finless bob's video series. It seems either the feathering shaft is a bit long or there is an issue with the grip.
