As well as having a std aero type roundhead the HG also has a different
crank,a longer 8mm plain crank threaded near the end with no steps in
it's diameter.The HG's were designed to cater for Heim heli mechanics
where the cylinder head is part of the fuz structure and clamps to the
std roundhead.I think it's a ripoff but they probably charge more
because they don't sell as many.I bought an SXHG for my Futura SE about
4yrs ago and it cost 240 bastard quid and i still had to sort another
cylinder head extension for it.It isn't better coz it's more
expensive,if that's what you were thinking it might be.I haven't a clue
what a HG-L is,probably a variant of the HG,the L means lighter,your
wallet that is:-)
