The new update and medium physics seems to help version 2 stay in a 'more stable' condition... Requires a skilled 'pilot' to fly this beast, as it always wants to put you into the ground. INSTRUCTIONS: no.1 engine/blade set up: you have to rev the engines to make the blades in opposite directions (one facing towards the front and one too the side is optimal). No.2: throttle up to 50% to get the engines 'spooled up' and to make sure that the blades dont explode due to contact if you havent followed step 1. Step no.3: throttle to desired % but keep in mid that iff you get the revs to high the blades may collide and explode... I found that around 65-75% was the best. WANRING: pulling Gs will likeley break the blades and also going too fast in combination with certain manuvers will cause blades to explode.
