What size of prop are you running on the engine setup you have on your Vanquish to get the numbers you posted on the forum. I have a very similar setup on my MKII but my 2.2 amp 4s pack might not run me up to at least 8 minuets that I need to go through the sequences. I'm using a 12x8E APC and getting on the Watt meter only 28-32 amps on a 40amp ESC. I have a new 3.0 Lipo that I've used but the extra weight and only same amount of thrust makes the plane a lot more sluggish. Any ideas or suggestions would be great.
