Matching mechanics to an old scale fuselage?
Hello! First post please be gentle.
I picked up a pretty old fuelage online, a Graupner/Heim Bell 230 and it was made to take the Graupner 'Uni 60' mechanics.
I have googled and cannot find the original mechanics, nor any reference to how big they were. My idea would be to fit it with a (near) equivalent modern mechanics but I don't know how I would go about determining what might be a good fit?
My question is this: What is a reasonably accurate way to match a fuselage with an appropraite set of mechanics? Years ago a 30 was a 30 and a 50 was a 50, now it doesn't seem there is a standard, or if there is I haven't understood it.
I have the instruction manual which states the following: (I will confirm when I have it in person)
Specification:
Fuselage length (excl. rotor) approx.1600 mm
Fuselage width (excl. rotor) approx.300 mm
Overall height approx.440 mm
Scale 8,1:1
All-up weight min. approx. 4900 g
The kit recommends blades of 688mm (if this is any help?)
Another post about building one, says the following:
'I am using the Miniature Aircraft Ion, which is an electric version of the company’s .90-size helicopter.'
Which would suggest .90 size mechanics would work, if that's a starting point?
Would hope to run it as an electric but open to suggestions. Thank you in advance for any help. H
