I've been running for some time model (construction) Sport and create me doing my first real Speeder (2/3). In Geschwidigkeiten> 300km / h the Stable should be. Since dealing with carbon is new territory for me, I resorted to this set and was not disappointed. The epoxy is highly viscous, so very thin, who wants to work on inclined surfaces, requires a thickener, the wetting of the Carboniferous but Excellent! My tail weighs just 30g, 2x3mm balsa with a little carbon in between, and is Brett Hart! But you should impregnate the Balsa (Schleifgrung), otherwise it will absorb too much liquid and is difficult. My first attempt to build the tail showed 48gr! I can also recommend the sheet down to the epoxy to load (temperatures, quantities etc.), there are also plenty of Anleitunhgen the net. The epoxy as well as the carbon is of good quality, gloves etc. one needs. All in all a good set for a fair price.
