is there any way to convert the digital wifi 5/8ghz fpv feed into analog that can go much longer distance? and more stable feed around obstacle?

so it was directly compabtible with 3s lipo esc?  or do i need some sort of converter?

18650 lithium batts are way too heavy ..
i use them in my vape devices

actually no. on a winged flyer, it's ok, but not on helis or cars that runs power hungry motors. while li-ion have the same voltage as lipo, it doesn't have the same Amp output. the C rating on a lipo is always higher.

a typical lipo, say 20c, 2000mAh, will give 40amp. a typical high discharge li-ion would typically be around 35Amp(2000-2500mAh), max. so a li-ion is not that suitable for aggressive flying, that requires lots of power. also note:

- high discharge li-ion are more expensive than lipo, per cell. noticed i said high-discharge, a 10Amp li-ion is not high discharge
- you are not suppose to run li-ion in parallel/serial unless the batt is made for such application(stated safe to do so)
- usually, the mAh stated on li-ion is over the actual value, especially on the cheap ones.
- 3x 18650 is pretty large as oppose to a 3 cell lipo.

try running a li-ion on a power hungry application as oppose to a lipo and you'll see what i mean. li-ion just don't do too well under heavy load. a typical scenario is that while your motors will end up at the same speed at full power(volts), li-ions will take longer to get there(amp/c-rating).

Is, SkyRC Imax B6AC good,
or I add 5USD more to bought Turnigy Accucel-6 80W + Reaktor Pro 240W 16A

Any local soldering kit intro?

That day I ago DIY shop.
I seen 60W and 100W soldering...seen not reliable at all
Because I going build a 450 size or above.
Please give some suggestion

Bro...help me take a look this spec...see its ok bo?
because at battery there I meet problem, all high C battery mostly are HXT 4mm bullet
Turnigy Graphene are too expensive...

Will this battery, 5.2Ah 10c typical, 20c burst can hold this spec quadcopter?
