@Bboy86 I would agree with @olds97_lss. The stock filter does a fine job, but if you do want an upgrade then getting the Motor Saver air filter would be the only other filter I would run.
Nicely done @carldav, I wouldn't have thought about using Tekno A-Arms, but those things look tough!
I agree with this as well, this is great info that needs to be shared with more people!
Looks like a possible second hand solution while we wait for Castle to make their app available for Android.
Then using something like the D-Link adapter would making programming quick and easy.
@JVT73 I've heard mixed reviews about the Dynamite kill switch. I've had the best luck with Killer RC kill switches and recommend people to use that over other brands.
That is a rather impressive charger indeed. If you get one please share your thoughts on it. I'd like to upgrade my hyperion as well, though I don't think I need a 4010duo level yet. :D
