The phrase "Downhill in a hurricane" comes to mind... I can barely get 100 out of 200W. And not exactly level either.

Sure it's possible. Just get a good motor and prop it for 200W, then add the biggest solid fuel model rocket engines you can find to your plane and let it rip. Just kidding, please don't do that, it's probably dangerous.

Well it's possible upon re-entry but it will be crispy before it gets low enough to get a radar reading....

rcjetpilot - its kevlar reinforced face and body shields. It can actually hold off a 50 calibre round too at 20 yards.

bigbarper - the new motor is a secret design made in China after learning so much from other manufacturers being their OEM partners. Well the new motor is not about brushless technology only but its now about running WITHOUT bearings. Its uses Magnametic Levitation (hang on lemme take another puff of the joint so I can hallucinate a bit more) hence taking motor technology to another level. As you all know friction and heat are 2 main problems with motors, they rob it of a lot of performance.
