Weight has a lot of impact, but I'm always skeptical of people that say one of their models flies so much better than another of the same size, especially when the better one is heavier.

I own several sets of helis, its amazing at how differently they fly with different FBL settings/blades/headspeed/etc. Nevermind comparing a worn out crashed heli to their brand new toy. It actually takes a lot of work to get two similar models to fly almost exactly the same. The best eye roll comparisons include someone else's heli they flew....

High disc loading definitely has an advantage on Windy days which I happen to have quite a few of at my flying field. This weekend at Las Vegas it was really windy and I'm glad I brought my Goblin 380 over my align 470.
I've also had some really calm warm days where my 470 really shines and it can be a lot of fun.

now when you get to the bigger sizes the disc loading may not be so important, especially a 700.

one tip on the 470 is to pull the boom back and pin it .

Yeah. But that's inverted. Try it on the skids. 😁
And when in the world did you pick that up?

You might consider it as an alternative to your P500. Only 499 from Cajun aircraft with motor and blades.

I weighed my three newest 700 helis, weights are all including everything except the batteries, but including tray.

Trex 700X = 3.71Kg (5.09 RTF with 4500mAh packs)
Goblin Black thunder T = 3.65Kg (5.03 RTF with 4500mAh packs)
XLpower Specter = 3.65Kg (5.03 RTF with 4500mAh packs)

All three are using HW 130A ESC (Align branded version on the Trex, the Trex and Goblin are using Scorpion HKII 4525 520Kv 'Ultimate' motors and the XLPower is using XLPower's own 4525 500Kv motor (slightly lighter than the Scorpion).

The Goblin has it's batteries taped onto the tray where the other two use straps, so i could save maybe 20g of the Trex and XLP if i used tape. All up weight depends on what batteries i use, weights range from 1.72Kg for a 12S 5000mAh Turnigy to 1.38Kg for my 4500mAh packs.

The XLPower could be made about 80g lighter by using tape to hold the batteries and the optional carbon boom which would get it under 5Kg quite comfortably.
