I am at odds with what radio to put in my Hirobo Bell 47g, I am still using 35mhz JR 9X and to be honest I have never had radio problems in 35 years of flying both Aircraft and helicopters.

The reason I am thinking of getting some 2.4ghz gear is because with the heli being gas I want to eliminate the risk from the spark ignition, my problem is do I get a Spectrum module or a JR 9X 2.4ghz.

I was almost decided and was going to get a Spectrum DX8 and just use this set for the gas machine to see if I got on with it but after reading loads of posts on here about total lockouts I am going off 2.4 ghz again.

Any help or suggestions would be appreciated.

Thanks.

I have been flying Vario gassers, various 3D helicopters, 4m gliders (tiny speck in the sky) and giant scale planks on Spektrum 2.4GHz without any problems for a couple of years.
I use four JR transmitters ranging from an antique X347, X-3810, 10XS and DSX9. All but the last have been converted with a Spektrum 2.4GHz module. The module works perfectly and the only thing that you sacrifice with the module conversion in comparison to a Tx that is built to 2.4 spec is the model recognition feature.
However with the gas/petrol spark ignition engines you must still observe the usual practices of keeping the servo and receiver cable runs as far as you can from the spark plug and spark HT cable.

I really like your Bell 47g, it must be a beauty in flight. I have a similar one built from a Vario kit. (see my gallery).

love your Bell 47G Gasser
i have been admiring your Hirobo Bell 47G Gasser and i have a few questions about the electronics set up and the mecahanical set up
i have only built and flown align helis before which i have found easy to build and easy to get parts information etc ,, this heli is rare and information is to say the least is minimal ,
the whole mechanics of the head collective etc seems stiff and basic .
what program do you use for the swash in your transmitter
have you varied anything from the original plan .
what servos and gyro did you use , what battery ?
does this motor have an exhaust or silencer ?
do you know of any build vidios or referance on the internet to this model
sorry to be a pain and have so many questions but i live in spain and fly alone ,,no input from expireinced pilots
this is my first attempt at scale and petrol . i love the model and want to see it fly at its best

some advice for you on the hirobo bell 47
get a spare set of the 0404-404 collective pitch lever sets
now use the L shaped one from the spares and use it on the other side of the pitch control (you will need to cut the spare length off) as the original straight arm is known to break

get a spare set of 0405-316 collective pitch arm set and the bearings 2500-033, you will also need 2521-064 3x6x5s collar and 2532-046 m3 x25 sus bolt
fit the bearings into the mounting arms and loctite the collars inside the bearings, allow to set
remove the aileron and elevator bell crank fixing bolts (2532-008)
bolt in the the extra pitch arm mountings and then drill he top plate and fix the arms with nuts and bolts to the plate(not on the left hand front one you will need to drill and tap as a nut will get in the way of the servo horns)

with these mods i should stop your 47 having the same failures as mine
the 0404-404 is known to fail on a few of them (also don't hold the blades in a blade caddy on the heli, always remove the blades and never pick up the heli by the rotorhead)

and the aileron and elevator bell crank pivots have sheared off in 2 seperate failures on the one of my pair of hirobo 47g2's and in flight causing a lot of damage
the other older one of the two has been fine (but will get the mods anyway)

as per the radio i fly futaba, had no problems with 35mhz on the gasser and none with 2.4ghz

as to the dx8, after reading a lot of posts with dx8 problems i would go the 9x 2.4 or the dx9
let somebody else be the beater tester for the dx8

and if you wish to see the mods on mine it will be at the red lodge helicopters scale fly-in june 2011

and for the parts world of heli in germany are a lot quicker than a back order through ripmax

Thanks for the advice on the radio, I have purchased a module for my PCM 9X2 for now to see how I get on with it.

Also thanks for the advice on the weak points, hard to believe that they would break unless you had a vibe somewhere in the head, all the years I have been flying hellicopters and nevere suffered such problems unless it has come from a vibration.

I must admit though I was looking at theses parts and they are stamped out of metal so I suppose they could have a weak spot.

I wiil keep an eye out for any problems.

Got loads to do to the bell yet so may even do the mods at the same time.

its only the later red one that has suffered the problems
the older yellow/white one hasn't suffered them

the red one is a 2009 kit
and the yellow/white one is a 1996/7 kit
