RE: First plane
Smo0,
There are a number of clubs around Sydney where you could get advice on a first plane. When I was down there I used to fly at SRCS out at Vineyard (Windsor Road) and the guys there were all friendly.
A hobby shop may be able to give some advise but it sometimes depends on who is working that day.
When you say Gas I assume that you mean Glow Plug (gas usually refers to a petrol engine which is not usual for a trainer). The question as to whether to start with electric or glow depends on a lot of things and a chat around the pits in a club is certainly the best way to get some opinions.
A lot will depend on what you intend when you have learned to fly. If you are going to move on with glow (or gas) powered planes IMO you might just as well start off that way. A lot of the guys at Coffs Harbour where I fly are training with Boomerang ARFs and they seem to be OK. I think there is a 40 and 60 size.
Regards
Terry
