Thanx guys,
I am back home and unpacking. Results are as you see it. I flew the same model like last year on WC in Landres (placed second). My model (Max) is good in turbulence, so it has advantage last year. This year in optimal conditions was enoughh for 3rd place. Looks like I will need better coach - like Richie - hic coatch is Geza and it is wisible
... may be I can add that he fly also MAX ... so at least little bit of my success
But to the electric - there were 4 electric models. My MAX was reworked model built for WC 2002 in Sebnitz (placed 10th) orriginnaly with OS MAX .46 LA with aluminium pipe. The empty weight was aproximately 1000g. It has now (and last year too) power train consisting of 6 cells A123 2,3Ah, Jeti spin 66 ESC, Axi2826/13 designed especially for F2B having little better copper filling (compared to the 2826/12 - IR is almost identical, KV is smaller) and my timer programmable by jeti box. I use only one battery fixed inside the fuselage and charging just before flight. Prop is APC 12x6. I have 2 models, one is 1800g (the A) and the second is 1750g(teh B).
Other 3 models were Czech in hands of Jiri Vejmola, Rado Dobrovolny and Pavel Benes. All 3 are the same system from my model, all reworked older models to electric.
The temperatures were up to 40deg. Celsia. No overheating, no flameouts, no troubles.
