I don't even need to point to controversial facts:
He says in his porting video that you should always port your cylinder so the piston never pulls back behind it, hang all voluming. Basically, he's saying make a useless port in your cylinder when you short stroke for no reason at all. He's also said the inverse: short stroke until the piston hits the port, however far that may be, hang all voluming.
He supports the use of Li-ion batteries, even for upgraded builds, which are factually a bad idea for airsoft because of how low discharge they are. Most are advertised as 5C (do the math on 3000mah batteries), but many, like Titan, have been tested to be more like 3C, which is of course horribly low. Titan batteries are also horribly overpriced.
Over on Airsoftsociety some of our members happen to be electrical engineers and possess the equipment to do true testing, and aside from Li-ions being terribly inadequate, most LiPos are also far lower than advertised.
aotsukisho If I sent you some packs, can you do an objective review on them? Two TITAN LION, one a 2600 and one a 3000. I want to see if the 3K is the same as the one you got from me earlier and then compare them to a KYPOM 2600/2700mah Brick . Plus I have an old Turnigy Bolt 2S High...

And here's a short quote:
"Final verdict.
Titanpower 2s 2600mAh: 10A maximum discharge, barely even capable of reliably running an entry level AEG. Don't buy this.
Titanpower 2s 3000mAh: 15A maximum discharge, bare minimum requirement of being able to run a stock AEG. Don't buy this.
Kypom 2s 2700mAh: Actually not bad measurements, just with a slightly overstated capacity. Best battery out of the bunch by far.
Kypom 2s 1500mAh: I am unsure about the cell specifications but higher IR than even the Titanpower 2600mAh so I would assume that this one tops out at under 10A continuous discharge. Double heatshrink is kind of weird. Would not recommend."
