walkeras are decent helis
but their spare parts not cheap and not easy to get locally

All are Ready To Fly (RTF) package, it means you have everything ready for you to start but may require setup prior to fly.

The first one and the second one should be 4 channels fixed pitch heli only. They are easy to learn compare to the third one, which is a 6 channels collective pitch and bigger heli.

If you want to go for the third one, you don't have to get it from OHS. LHS already selling this Belt CP V2. Anyhow, try to get the newer version, Belt CPX that is a newer design. But ah, Belt CP heli is not so recommended unless you are not willing to spend more.

This LHS, rcdreamz carries walkera heli as well but I think you should compare the price first tongue.gif
Also, importing the whole heli and transmitter from oversea may bring you some problems dealing with our custom.

So walkera>belt cp helis?

What is not so recommended feature of this belt cp actually?

Besides buying the whole heli package, what is the maintainance cost like?

I'm thinking of getting the flyless bar version helis, looks easy to fly.

the cost of a BMW and a MYVI is not the same
maintenance costs oso not the same
looks oso not the same
but they can both get u from point A to point B

basically the same reasons stands for helis as well ... get the idea ??
most of the time u get what u pay ...

Most obvious one is the stability, easy setup and 3D capable (pilot skill not counted of course tongue.gif) compare to a Trex.
So in other words, bcp is not so stable, hard to setup and not so capable of doing 3D stunts.

Maintenance cost? Depends on how frequent you crash, a Trex minor crash would have to cost you at least RM100 already but probably not much difference for a belt cp to crash. Battery for a 450 size heli is quite affordable nowadays so the cost should not be very high. One 2200maH 35C 3S LiPo is around RM80 and if you taking good care of it the battery can last quite long.

For example I have one for my belt cp previously, after a year I still can use it on my trex now for sport flying. There are at least 100 cycles of charging/discharging already.

Anyway, what's your budget first? It would be easier to give you suggestion .....

Hehehe, yes they can both get u from A to B but the speed is different ......... agree?

Actually my budget is up to Rm600, fitting for a myvi in this case.

Trex is above what i've expected, so still considering. Reluctant to break my budget... =P

Is flybarless really that good?

I think it's down to either

or

Not sure how good is the stability of a fbl because i have none. But i do believe it is better than a f'barred one.

Since you are still new to this hobby, i SUGGEST u to take the walkera FP heli first to feel the poison. Then maybe u r willing to dump in budget for a better heli later.

But if u want belt cp u should get this newer version,
http://www.rcsmart.com.my/webshaper/store/...roductItem=5048

Still less than rm600 exclude shipping.....

Why not suggest him lama v3 first and a pheonix or realflight?

Anywhere where is ccfook eh? He's into Poodle and Tarantula (from his post) now ea, not into Heli anymore? blush.gif

given a choice between the BCP and walkera ... i would take the walkera anytime
its and FP ... lower headseped and much smaller so crash impact would result in almost no/minimum damage ... and it has a 3axis gyro which is very advantageous

mr shock ... the FPV set wanted by someone who wants to play around ... thanks for your interest

Actually ah, anyone heard of burning the receiver before because of servo drawing too much current?

For example if the trace of the PCB of a receiver can only handle 5A current max but if all the servo can draw up to 10A will it actually burn up the receiver because of this?

unlikely ... coz the current/power supply on the rx board are parallel
so if your servo draws very high current it will just pass thru transparently in the receiver .. current goes straight to your servo
never heard of a receiver burn coz of that ... most rx KO coz of crash and maybe burn in fire of crash ... hehehehe

having said that ... it is best to range test your rx if u have had severe crash with it b4 putting it into the next model
the UFL connectors inside maybe damaged of broken ... its super duper small

what kind of range are u looking at ??
what is your budget ??
are u willing to trial and error on lots of things coz placement components and RF interference can make a big difference
can u DIY some stuff ??

overall ... if u are looking at 1km or so range with good reception (provided your RC link can do it)
u do not need to spend much ... if u looking at hobbyking stuff ..then less than rm500 but the goggles there are OUT OF STOCK since dunno when ... hahahahaaa
oso depends on what u wanna do ... fly obstacle course (low and fast flying) or go high high see here and there ... or wanna go far far break records ... hehehehehe
that will determine the kind of antenna system u would wanna use ...

Maybe I should re-phrase my question like this:

Think about a thin wire which can only sustain 1A max, if we are flowing 10A current through the wire I believe it may burn or melt down the wire. The printed circuit board has the traces to make up a circuit board, the traces are analogy to a wire in fact, it has its own specification as well.

So I am just asking if anyone experience this before. The receiver, I believe it has its own maximum current it can stand with, just that not really sure how much it usually can go .........

I found that my receiver is slightly warm after a flight and after using a higher ampere external BEC ...... sweat.gif
Hehehe, just curious only ......

the pins in the rx is wired/soldered parallel ... the current handling capability of that is much higher than of the wire in most servos .. your 450 only have small little wires tongue.gif
try this .. do not plug in anything ... leave your heli out in the sun where u usually fly ... then after 5mins ... touch the rx ... see whether warm or not .. hehehehehe

Hehehehe, nvm lah ... forget about it because I heard people using the same Rx for 600 size so 450 size should be OK tongue.gif
