guys, im new here and im very interested with rc hobby

.
ill be in Hong Kong next week, have seen some shops there (on my previous trip) with a lot of RC stuff.
any guidelines who can share on what to buy? im more interested with the gas type rc's since mura sad ug tinuod with the engine and all. are there sizes too that i should take into consideration?
if i buy in HK are there spare parts here in cebu that we could buy in case we need to replace in the future. what brands do we have here? and the consumables like the fuel being used is it availbable in cebu? i notice it was greenish in color.
hoping you guys could help..
