I have a 110 in another plane with a Turnigy 100A ESC (3.1 oz). I'm using two 4S Turnigy 2650mAh batteries and getting an easy 6 minutes and can push 8 if I wanted to. The plane comes in at about 8.5 pounds. I think the difference in weight between the Flightmax 4000 and the 2650 is 13.4 oz for the 8S pack. This would bring the weight of the Funtana to just under 9 pounds. Can you tell me what your flight time is like with the 4000's? I was thinking about this plane for my current setup and if I can't get the weight down to under 9 lbs and get at least 6 minutes of flight time, I may have to consider another plane. The only reason I was considering it in the first place was because a Web site that sells the plane reports the empty weight to be 69 ounces (4.3 lbs) and my hardware would bring that up to 8.5 pounds, which is 175 Watts/pound. Sounds unrealistic from what you guys are reporting.
I was using Turnigy 2 - 4s 4000 and decided to get some of the new Flightmax 4s - 4000 's. So they came in yesterday andsurprisinglyenough they are about 180 grams lighter than the 5000 's I have been using and 80 grams lighter then the Turnigy. This should make a huge difference. I stand a bit back from original post that this may get the plane close to where I would like to see it for electric flight. I get good flight time with the 5000 setup and see no reason why you shouldnt get 6-8 minutes fom the 4000. As soon as it gets warm I will let you know.
