heli any part is replaceable laa ... so no big deal
hehehehe

then buy new one lorr ... 2nd hand stuff hard to say one .. hahahaha
or u buy kit and put in the electronics yourself laaa

my 450 PRO up to date has only had 2 minor crashes
thats over 700 flights MINIMUM
head and all still intact from day 1
the secret is SIM SIM SIM ... hehehehe

that is the CORRECT way ... not STINGY way .. hahahahaa
but of coz if u rich and can always send heli to shop for repairs and maintenance then can throw away the SIM .. hehehe

nvm la ... slow slow wait
not like u have no heli to fly .. hehehehe
eventually can find something for your budget one

if u go to the shops and tok tok to the boss direct .. it is possible to get prices that is lower than that shown on their online listing
oso u have to be familiar and regular shopper there la to get good prices .. hehehe

yup ... price is cheap but the shipping weight abit not logic laa
279gm ??? even kwai lohs complaining about the weight ...
need 40C meh ?? hard 3D need la ... hehehe

had my 1st FPV flight today ... flew to about 500m out and 150ft high
no probs with video and RC ... after many months of sitting and waiting .. hahahahahaaa

it was way FUN FUN FUN !!!!
conventional RC might have to take a back seat soon .. hehehe

mr shock ... how is your FPV coming along ?? or not coming ??
very affordable now .. hehehe

if u go budget budget setup ... goggles + Vtx Vrx + cam ... apprx usd250 or less
then if u wanna add GPS and all other kinds of sensors ... those will be starting to get expensive ... hehehehe

they have all kinds of sensors depending on what OSD u buy
sensors to measure GPS coordinates .. airspeed.. pressure .. temperature .. etc etc
the RTH (return to home) function is something that comes with the OSD unit and will utilise 1 oe 2 channels on your radio to work

all see your pocket how big only ....
but with unproven walkera 2801 .. dunno what is your range oso
always start with basic stuff laa .. cheap and fun until u learn it ... then can decide whether u wanna spend sommo $$$ or not .. hehehe

take it up high high .. better chance of recovering just in case
but of coz high high much harder to see orientation oso laa .. hahahaha

ori tail blades are not CF ... they are plastic
length is about 64mm ... slightly longer than the trex450 v2

no recording device ... only using goggles to fly
dunno if my old video cam got RCA input to record or not ... if got i will try and see ... hahahaha

seriously ... once u have tried FPV the normal RC seems .... NORMAL ... hahahahahaaa

u try 1st ... or try asking if someone around where u fly is flying FPV
i am sure they will let u try try the goggles while they fly
only then u will know the "feeling" of freedom of flight ... hahahahaa

there will ALWAYS be interference for FPV as it is ANALOG for now
just like car radio ...
the videos u see in youtube that are free of interference are cameras mounted with onboard recording .. the ones u see with interference are those live streaming ... it is just a matter of how good a reception can u get

so far i have flown to about 500m radius without loosing video ... there is interference of coz .. read FPV in RCG and u will know
later will DIY/modify antennas to improve this .. not expensive but need to read up and learn

if u dont order lipo or big size planes then normally HK will ship out within 2 days ... and from the date they ship out normally takes 3-4 days to get to your doorstep

u will LOVE your 450PRO and soon the BCP and parts will be up for sale .. hahahaha

order the medium strength locktite .. usd0.99 only .. use that to lock your screws on the PRO ... its is good enough ... damm big bottle and CHEAP !!!
if u use CA then much harder to open the screw compared to the medium locktite

dis-assemble the PRO completely and rebuild ... coz u will seriously need to locktite the head parts properly at the speed the 450PRO is turning the blades .. helifreak tech room got the 450PRO build .. very ez to follow

i heard the gp780 is more sensitive/temperamental compared to the gp750 so balance everything and minimise vibs

yes ... i lube them with silicon grease GENEROUSLY
the combo package threadlock i did not use .. scare too tight later open screw strip kow kow then die

there is no pleasure is viewing the BCP laa .. hahahahaa

heat up your soldering gun kow kow ... then heat up the screw to remove stubborn threadlocked screws
thats why i said to open everything up and fully rebuild .. ALIGN do half half things one ... hahahahahaaa

dont have to grind flat spot laa
running thru gearing system not as stressful as direct drive so just put some threadlock on the grub and tighten it onto the motor shaft
but of coz if u choose to grind a flat spot on the shaft it will be more secure laa .. hehehehe
