Hey beepos and beepas,
this still applies to Smash 4:
If you Gyro drop then immediately do any aerial attack you will still hold the Gyro while doing the aerial attack. This is a very basic technique that also was in brawl, but it's very useful imo and i haven't seen that many ROBs do it.
I find it pretty easy to do it with nair since I wont have my thumb on the control stick at the time of doing my nair.
What I like even better is to do it with fair, but the way I do it to make my life easier is: Set up taunt to grab. That way, then I take my thumb off the stick and press grab, I will always z drop and not hard toss, and then I'll just do my fair with the c-stick.
You're right, not a lot of ppl do this. We need more of it.
I learned something today that can be implemented into your game to slightly increase damage output with ROB and the Gyro.
Essentially, when you throw an item in Smash, it can be thrown at 2 strengths, with varying speeds and damages. For most characters this is largely irrelevant information competitively (and is never something I have heard of before, I rediscovered it in the 3DS waiting room). For ROB, it can tack on a little more damage with the Gyro. A normal throw does 9% whereas a Smash throw (performed as the name suggests) will do 11%. For Wii U players this may be unnecessary info (I am not sure how throwing with the C-Stick works) but as a 3DS player it's certainly useful.
(This is definitely not new as it is mentioned in the Smashwiki article on item throwing. One of the guides also mentions 10-11% for a directional gyro throw though that is not what it really is - you can walk, throw in same direction and only score 8-9% damage. Other guides I saw didn't seem to mention it at all. My assumption is it may already be done through C-Sticking on Wii U but I thought I'd post it for the sake of 3DS users if nothing else.)
We usually refer to the tosses as weak/soft toss and strong toss. In Brawl, you used to be able to glidetoss a weak toss, which would make ROB glide with the gyro while it was being launched, and he could recatch it! It was insanely hard but I was getting it pretty consistently towards the end. See video:

(I would embed it here, but it has swearing in it)
Anywho, how to do the tosses:
Weak toss:
While standing still, press A.
While walking (no matter the speed), press A.
While airborne, press A (no direction).
Strong toss:
While running, press A.
While standing, flick the C stick.
While airborne, flick the C stick.
While airborne, hold a direction and press A.
Edit: after playing with this some on my 3DS @ work, I'm actually getting a little confused on how the gyro is behaving. I'm starting to question if I'm hard tossing or soft/weak tossing. Hmm, I'll figure this out tonight when I'm home and with my Wii U. So check back tonight.
