smallest helicopter that can do a proper loop and roll

I've been trying to expand my flying slowly into 3D. I recently bought a Blade Nano as a "real simulator" and have had success with inverted flight. It is very resilient but cannot do a nice loop or roll. What is the smallest helicopter that can do a proper loop and roll? Thanks.

The nano can preform a good loop or roll if you use good collective management

Thanks for the reply.

When I attempt a loop with the Nano, (with proper collective mgt) it still looks more like a extended flip to me. And a roll is a very sloppy corkscrew. What I'm looking for is a nice big loop and a axial roll. What do you think is the smallest helicopter that can do this?

I dunno. Try posying in the electric heli section

I would say the V120d02s or 130x since they are both powerful brushless helis.

Maybe just a brushless upgrade on your Nano? Sounds like it just hasn't got enough guts currently to power through a loop the way you want it to

Thanks to all that replied.

My Nano has the brushless conversion. When I pull up during a high speed pass, it won't carry the momentum in an arc like my Trex 450, it just flips on it's back. Has anyone seen the new brushless mcpx do a loop and roll like a bigger bird? Or is it just asking too much of these smaller helicopters?

I only see people doing tight flips and hard 3D with these micros. It's really cool, but I'm not ready for that yet. Like to practice some FAI style loops and rolls. Thanks.

As Helikido said V120d02s V2 or 130x is a good choice considering they both have shaft or belt driven tail instead of a tail motor. The tail outputs will be more precise and responses will be better.
If you already have a decent Spektrum tx go for 130x else consider the v120. But I am not a big fan of linear servos could in smaller blade helis.
Anyway if you get the v120 and a decent Devo tx, you can use the Deviation firmware to fly your dsm and other other models which use different protocols.

Guys, quite frankly a loop has very little to do with "power and guts"

A larger heli does them nicely because of the weight. A nice loop has very little negative collective/pitch at the top, and is more so just like a fixed wing plane flying all the wah through with momentum. This is greatly the same with a roll.

I know I can do both with my old V120D02, however they are nicer with a 250, and nicer yet with my 450.... And so on...

mcpx bl (3 min 41 sec)


I didn't do any fast forward loops as I was more close in flying, but there are a few decent small reverse loops in there, one around 2:09.

It can do quite large loops just like my old 130x's and 120's, but only when I am running the stock tail. When I am running the kbdd tail it doesn't like reverse loops so much

The nano has to less mass and power for a real loop but is the best "crash and fly again" heli.
The brushed MCPX can small loops but need strict pitch management to prevent the tail blowout.
The MCPX_BL can huge loops and the tail hold even with the stongest pitch.
Maybe the best compromise between small size with crash resistance and flight cpabilities.
The 130X fly a little more stable and precise with the pitched tail but is the biggest "small heli" with lower crash resistance.

Thanks for helping me narrow this down.

The backwords loop on the video was really nice with the mcpx bl! Can it do an axial roll as well?

I may be asking the impossible because of the mass of these little helis, I didn't think of that. But the mcpx bl looks promising. It the tail and power are not problems anymore with the double brushless than I may go that route.

Does the mcpx bl hold up pretty well in a crash? Thanks.

It really does take some mass to smooth things out for a plank style loop. You can cheat a bit tho with a heli by feeding in collective on the way up to get some speed to put you over the top and then ride out the loop with that energy. It's still tough to do a really round loop with 100s. You can also just do a stall turn type loop which is alot easier since you're taking advantage of running out of energy at the top anyways.

That's good to know - I've been practicing a lot on my sim, so I thought I was ready. The little nano did a completely different thing in FFF when I pulled back and went vertical and started lowering the collective. It was on it's back going in the opposite direction and falling! And the roll looked like a wild looking corkscrew that lost about 30 feet of allitude to do! Having the BL main didn't seem to help at all either so you're right. It's a mass thing.

But this little Nano is a blast to fly!
