Well my son maidend his and had 8 successful flights, including 5 deadsticks because of the small tank. i thought it had a 11oz tank and he wasnt sure so i set it up for 12 mins the first flight ,didnt make it,nice deadstick landing, thought it was the engine and worked on it and took off again, deadstick , nice landing, worked on engine again(cleaning everything) and deadsticked again, all at about 7 min into flight and then things began to click and we figured it out and set the timer for 7min and landed with hardley any fuel. How many oz is this tank? i dont have a conversion chart. but the evo 46 would run 10 min easy with the h9 arrow 11oz tank. any way here is some pick of our planes and us, and here is my blazer Kokomo. Later!
