F6 and S1 with the odd grid at other venues as well as the TKM festival etc.
Very good engines, that can run for almost 80 hours between rebuilds if maintained well (oil change every meeting). Rebuild costs vary depending on wear, my last bill was around 500 but as I say that will last me 2 years hopefully. Engines are sealed and can only be rebuilt by Tal-ko which helps maintain consistency.
Large range of chassis available as Rotax specs can be used. Tal-Ko, MS, Arrow, Gillard and some others are used.
No massive grids, but reasonable and good value for money with none of the bulls**t that you see with other series around engine components.
Hope the above helps.
