My grandfather recently passed away and left me his 25 year old hirobo shuttle.

I has only flown once because the starter belt snapped and he never got around to replacing it.

I wanted to know if anybody can tell me what i need to get this thing running.

I need to know the type of glow fuel
the rotor setup as i was told there is somthing wrong with the rotors by a hobbyshop owner and anything elsei may need to know.

It uses an old FP-G154 futaba gyro

Fp-R107N radio 6ch on the 60Mhz band with a 60.2Mhz crystal.

All the electronics work, only issue is the engine.

Would it be possible to convert it to electric??

by the way, Sataba is South African futaba, as he lived in SA where i was born

i'd remove it from the scale body
clean the engine and carb
replace the batteries,switch and fuel lines
get the head looked at
clean and check everything
give the radio a good range check
and fly the heli in its pod and boom format
once the heli is flying well then refit the scale body

yes i removed the body, removed the engine, it was completely ceased so i cleaned what i could, sadly the carb screws that hold it to the engine and the head of the engine screws are completely ceased and are stripped so i cannot remove them, but i did manage to unease the engine by heating it and spraying WD-40 smf cleaned the carb, and
I have got the engine running!!!!

but i have a serious issue with it.

Firstly it wont run when on its back, it will only run when flat or at a 45 degree angle, i dont know what is wrong that it behaves like this, but after getting it running out of the frame, when ii put it back in and tried to run it, it would not start.

At the the moment i tie a string round the shaft and pull to starts as i have no starter box which makes it more difficult, but regardless it should still start, i have tried priming it etc but no matter what it will not start when in the frame.

another issue is needle setting,it seems to run with or without the mixture needle in the carb, if i completely unscrew it it doesnt make a difference other than completely screwing it in when the engine then just cuts out.

is a new carb the fix?

the orings on the carb where it mounts to the engine, are they soft?

what motor is that, I belive the carb has small oring on the needle as well

the fule should come out the slit on the brass rod in the center of the carb,

its not the orings that are the problem, the carb itself is fixed onto the motor because its two screws are stuck fast

The needle has no oring, the idle screw does though.
I have cleaned out the carb so it should be fine

to remove the screws
cut a flat on the heads
and then heat them up with a soldering iron
they should then undo with a flat blade screw driver

I just went back with my grandma to try find the starter box in his packed boxes but no luck however i did find 3 glow engines.

Two are for control lone by the looks of it, one absolutely micro engine, so small.

One slightly bigger and one relativly large one.

The two control line motors have never been used or run but do turn over. and their glow plugs still work.

I will try fix the large one and use it in the heli as it is in a slightly better condition.

I would like to know how much these are worth, considering they have their original boxes and manual for one of them and that two are effectively brand new, then their is the fact that they are rare, Made in america!

i could sell them and buy the kit needed to get the heli working.
