Good morning shiners! That forlorn package sitting at the Shenzen airport finally landed at JFK and cleared customs last night. Now USPS will take it on a tour of the surrounding area by visiting NJ and CT before bringing it the 45 minute drive from the airport directly to me. Too bad they won't let you send an Uber to pick it up before the bizarre grand tour begins.
I have a ss flat wire contact coil at 0.58ohm in the recurve now. With a brand new battery in the mech, it starts off mehish and gets meher

as I go.
30W works for me on this build now on the regulated mod.
I usually go for around 0.5 ohm when I build any coil.
Am I right in assuming that mechs do better with builds lower than 0.5ohms...say in the 0.1-0.3 range?
Don't forget Ohm's law and you battery choice. A 0.5 ohm build will draw 8A (at 4.2V, the max voltage you always need to use for calculating on a mech), a 0.3 ohm 14A, 0.2 ohm 21A (time for those 25A batteries you have around) and 0.1 ohm 42A, beyond the capability of any single 18650 available on earth (or 20x series too).
Building below 0.3 ohm really starts to complicate stuff like battery choice (I like that I can use a VCT5a 25A or a 25R 20A depending on what's around that's charged). Below that and you need to pay attention to what you're really doing. A Samsung 20S will give you a 30A CDR and 2,000 mAh capacity if you want to venture into the 0.2 ohm realm. Anything below 0.2 ohm on a single battery mech is going to be pushing the limits of what you're working with and a place I don't venture.
Another factor is the more metal you use, the more metal you have to heat up and the slower the ramp. So simple round or a Clapton with a single 28G core seem like good fits for my style. Generally my builds run a bit hot on a fresh battery, but then become nice and pleasantly warm for my tastes after the battery voltage drops a bit, which is pretty fast from 4.2V down to 4V.
This is the drawback of a mech anything. The only control you have is over your build. No fine tuning with preheat or wattage tweaks. You have to figure out what build works best in what atty, and then I just always stick with that build from that point on. So it's more than just choosing a resistance, it's choosing the build/coil design as well, and what works on your regulated mods won't just translate over to a mech.
