So my guess it either a thinner airfoil at the wing tips, you know how most delta wings are thick at the middle and get thinner, or move the CG back and put a gyro on it.

Maybe the thickest...

Thanks for looking out, but I know a bit about that stuff. I had a factory rated 200A ESC, I looked up the data sheet for the FETs and found it's true rating to be 129A, but the heatsink helps some,...

Using a 4s saved me from buying a bigger 3s. I still have great throttle control, 5s would probably mess up my throttle range. Anyway, being able to use my two 4s lipos gives me 2 extra lipos for...

You are missing my point, I consciously keep the throttle low when using a 4s so I am running it as if I was running it hard on a 3s. It still is using the same watts as it would on a 3s, so it gets...

If you are talking about peak amps from acceleration, their duration is so short that it is likely still within the ESC's burst rating. I've run my hobbyking 30A ESC hard on my slow stick at rarely...

My explanation was considering you are using a big enough ESC, and keep the throttle low enough to not have problems, and the higher voltage at lower throttle will keep the amps down even more. Don't...

Increasing battery voltage doesn't necessarily increase motor amps as long as you use the same motor rpm on the high voltage lipo as you would on the lower voltage one. This involves not using as...

I'll have to check out Heads Up RC. I'm using a blue hobbyking 30A, cost $8-9, it takes all I throw at it, but yes, always go bigger on the ESC because if it is rated for 30A likely that is 30A at...

I think hobbyking has the best prices, I look at reviews and see why the bad ones are bad: is it the reviewer, a minor or major flaw, different specs, misuse. I think the NTM are pretty low on...
