Ken's setup happens to be almost identical to what we used on the 48-oz Vector 40 (until it got flattened by my car... ahem), which is (was?) a 536-sq in plane vs. Twister's 510 sq.in.
- Another vote for Cobra 2820-12 (930 kV). Excellent little motor, and will grow into slightly bigger planes like the Vector 40, Nobler, Cardinal, Legacy 40.
- I would say that a 35 AMP ESC (such as Phoenix or Talon 35) is more than sufficient, and will save you another 1/2 oz or so.
- Depending on the final weight, you can use either the 10-in prop or 11-in prop. Not sure whether a 9" prop would give enough thrust for overhead maneuvers.
- I agree that Fancherizing would make Twister fly better (better defined squares), but that would also disqualify it from being Nostalgia legal, which was one of your criteria;
- Also, since the main feature of "Fancherrization" is lengthening the tail, it allows heavier battery up front. If you stay with the original Twister dimensions, a smaller battery might be in order. Unfortunately, I can't trust the battery weight data shown on the HobbyKing website, as I compared actual weight of one of my Zippy Compacts to the advertised weight and found a whopping 2 oz(!) difference. So, Ken - could you please weigh your "Turnigy 2800mAh 4S 30C LiPoly Pack w/ EC3" and report the weight here? I was using 4S Zippy 3000 at 285 g, but those are not even listed anymore.
- I'm not sure I agree that smaller motor would allow longer flight times. Usually, it's the opposite. Larger motors have less resistance, therefore they heat less, and end up using less battery.
