    Yes, any difference is probably too small to notice. The 'upgrade' was more out of curiosity than any expectation that it would make a significant difference.

    Just a quick heads-up.. Banggood have a 1/3rd off sale on the Devil 420, so the total price for the 'Super Combo' which has everything you need except battery and Rx is $310. That's a real bargain in my book: ALZRC Devil 420 FAST FBL RC Helicopter Super Combo

    The D420 is quite a bit smaller and about half the weight of the D505, so the 505 will fly noticeably 'bigger'.. i.e. the larger heli will be smoother and more stable especially in the wind. But for a heli of it's size the D420 flies great.

    That is nice. I really didn't want to go smaller then a 450. Since I put my Tarot 450DFC set up into a CoastGuard fuselage, I've been looking for a small bird to toss around in the tight area were I like to fly at :). I have all the electronics and this looks like it might work for me and the price is right too, I think. Devil 380 FAST FBL KIT BLACK ALZRC - ALPHA RC HELI - Drones | RC Helicopters

    That's a great deal.. Bear in mind though that you need a different power system to any '450' size heli, so if you have those parts left over from a 450 they arent going to work. The 380 uses 6S for starters but also it's bigger and heavier than any 450 and needs a bigger ESC and a larger motor with much lower Kv. The servos are the same as a 450 but you need decent quality servos in the 380.

    Thanks Smoggie for that information. Your absolutely right. I do have left over 450 parts and once again I wasn't thinking right, like always lol. I don't need another 6S heli. I have my X3 and she's fly's wonderful with the set up I have on it. That's OK... I'll think about getting another 450 then and this will work fine and the price too :) Devil 450 Pro V2 SDC/DFC KIT BLACK ALZRC - Drones | RC Helicopters

    I finally got around to installing the KST 'Contactless' servos in my D420. I've had these servos for a while but just never got around to fitting them because the regular KSTs seemed to be performing fine. These new contactless servos as well as using hall effect sensors rather than regular 'pots' have a lot more torque than the regular KSTs. They are a bit pricey but I got a deal on them from Banggood when I did the original build review for the 420

    I also fitted a HW 80A V4 ESC while I was at it, this is not really necessary to be honest, the 60A was doing perfectly ok, but i had another home in mind for the 60A. The 80A is a little heavier but that's not really a bad thing because it reduces nose weight requirement.

    Nice going Smoggie. After watching your video I'm charging my 500 batteries so I can sneak a few evening flights :)
