Smallest available Nitro Align

Did you miss where my Trex 700N (full) weighs a pound less than yours empty? Sure, the canopy is half a pound - but that's still a lot less. The three blade on yours adds a lot of weight.

I've done the super light electric - I had a TT E700 that was just over 10lbs RTF with 12s5000 using a 600 class motor to keep the weight down - smoked the motor, just didn't have the current capacity for the way I fly. The nick maxwell motor put it at 10.5lbs, eventually converted it to nitro and dropped half a pound again. Wound up retiring the airframe because it kept eating torque tube gears... just a little too lightweight.

So sure, you can build a heavy nitro or a light electric, but in my experience the typical 700 nitro with a full tank is going to be about half a pound or a pound lighter than a typical 700 electric.

nitros are quite a bit lighter than electrics plain and simple. my trex 700n was 10.5lb full of fuel. btw, look up the weights of a ys 91 and a ys120. the 120 is LIGHTER (same outer dimensions, larger bore, lighter). So no, a smaller 91 isn't a reason for a lighter heli. I would definately second guess the 12.5 to 13lb weight for a trex 700n. that's way to heavy unless its carrying a gigantic rx pack. i wpuldnt trust either of those scales shown for accurate weight. i use a 5 kilo gram scale for weighing heli stuff. accurate to a tenth gram. when comparing nitro to electric, forget about the airframe for one second and just think about the difference in power systems. a 12s electric carries 1500 to 1600 grams in lipos alone. add a 500gram motor, 200 to 300 gram esc, that's about 2.3 kilo or over 5 pounds. a nitro has about a 550gram motor, 200 gram pipe, maybe 600 grams of fuel when full, and an extra 60 grams for throttle servo. thats under 1500grams for a nitro power setup compared to a 2300 gram average electric power setup. pretty big difference
