Nano S2 great training tool - worth upgrading?
Well I have to say I have reignited my heli passion with the little Nano S2. I had it on my shelf thinking it was broken somehow and that I should leave it alone. Indeed one of the bottom canopy posts was broken but I flew it and it was ok. Then I found an old CPS that I had before the Nano and the frame was perfect so I swapped it. Found also the spares bag that came with the Nano and now I have new main and tail blades so basically my heli is as good as new.
I started doing the very basics and quickly found out my inverted was not as good as I thought it was after my experience on the sim. Quickly I realized my inverted piro hover was not as burned in into muscle memory as I thought it was. But the little thing crashes like a champ and dozens of crashes later it flies just as well. This little thing is a jewel for doing that basic training. Now that the cold weather keeps me indoors the Nano S2 in my basement is my friend. I then realized my pack were really bad. It kept bogging and had very inconsistent power throughout the flight. Also flipping it other than the first twenty seconds of the flight made it bog and blow out the tail. So I got 6 ProTek packs as I have the six port USB charger from Spektrum and what a difference. Now I realize that it is very inconsistent still and although it has helped me to replicate wind conditions as it has a mind of its own and forces me to keep correcting, which is good, I do want it to be more precise. However I fear the little motors will not handle any additional weight from aftermarket parts. Is there a good option for replacing the motors so that it has both better power and no tail blowout if I make aluminum upgrades that increase the weight? That would decrease my flight time but I hope not too much and that I can have a better more stable machine. I know the M1 seems to be a fantastic machine and I want one but I think the Nano size-wise is a better option for the space I have in my basement. I would have to tone it down probably anyways to avoid breaking stuff. The Nano crashes against the drywall and furniture and leaves no damage nor causes itself damage either. I fear the M1 would be a different story, maybe with less headspeed? I don't know. Anyways exploring options, but to be honest I am happy with how it is and how inexpensive it would be to repair when eventually something does break. Cheers!

I can't comment on if there are any better brushed main motors available somewhere.
But I would stay away from doing any carbon fibre frame or aluminium head upgrades. The only thing you need is an aluminium swashplate. That's it. Also I would stay away from going BL on this Nano. The best upgrade to a Blade Nano: XK K110 (1s, BL main outrunner motor). For indoors maybe try a XK K100 (double brushed). No idea how long the main brushed motor might hold. HorizonHobby has increased the price for the main motor from ~13-14-EUR to 16.99EUR. I find this price ridiculous for such a low QS product. I don't own the Nano S2 or S3, but had the NanoCPX in 2012/13. The OMP M1 and M1 EVO is 2s. Isn't that too much for indoors? Might fit a big triple gym if you don't constantly crash against the walls or hard floor. The alternative could be an Eachine E120s / Yu Xiang F120 (2s) as it is BL already uses a similiar Trex 150 connector but uses a brushed tail motor (with a plug for quick swap). I'm hesistant in flying a Nano or K110 indoors in a living room to be honest. Cupboards, walls, chairs, tables, plants,...are all your enemy. And the Nano board electronics is sensible. Do you really go inverted & stuff with that Nano in the basement? I need lots of room for any 3d / inverted stuff....so outdoors or a triple gym is much better for that than a small European living room or a basement/garage. I don't get that much out of only hovering a squirrely micro CP heli indoors. And any crashes and repairs are costly and very time intensive on that Nano (broken off canopy pins = full frame exchange; unplugging servo cables might damage the white servo sockets if they are not additionally glued onto the board; had one coming off back in 2012 - a disaster). Nano prices are too high, especially that board, to crash it against other stuff. Over time this might corrupt the SMD electronics, brushed motors or a Mosfet might burn. The complicated SAFE S2/S3 stuff probably makes it even more sensible than a NanoCPX already was. I didn't get out that much when plastic parts or plastic swashplate constantly broke. My choice for indoor "CP-like" flying: Blade Inductrix quad (red acro mode). Other alternative are the Tinywhoop style quads with Silverware/NFE firmeware (acro/rate mode). A ducted fan quad chassis is better controllable in this European living room; even the downwash from a micro heli and fixed throttle.... With the Inductrix I can fly over tables, having standing and ceiling lamps close, no issue with plans, chairs, etc. The only thing which I would hold back a bit are BACKWARDS flights. When I did and fell out of the curve once the Inductrix heavily crashed against the wall, cupboard and from there with props first onto the hard floor. Autch. In this way you can corrupt brushed motors. Now I would need to replace one as there is a heavy drift (somehow it got totally blocked from the crash, now it spins differently than the other three trying to get it going again a bit). Inductrix uses 6mm motors, BetaFPV brushed frames 07mm motors. Well, every penny you throw at HH for more expensive Nano parts means they this money goes down the hole in the purse. There's no stop. Had a full box of spares. This 30g thing sometimes will even break (ultra-thin landing gear, plastic swash, 2-4 canopy pins, main brushed motor, board, Mosets, antenna, LVC) even when you look at it for too long. If you can do 3D with it and inverted 8s curve flying, funnels, backards flying, piroflips, etc. in the basement or smaller indoor rooms: Congrats. You're the (stunt) pilot. But I never got the hang of it how HH pro pilots did their inverted hovering stunt in the shower video. Would like to see the background story how they filmed it. In a gym with a high ceiling doing flips and going inverted or practicing backwards flights might be much better duable. But my first floor room tries of this back in 2013 were everything else from successful - not in tight space. Too many things can go wrong. Sounds you're doing much better than me. But still, I would stay away from any additional and costly tuning. FYI: In the last three years I only have broken a canopy pin one single time on one K110. The XK plastic is MUCH BETTER!! Have been flying and crashing the crap out of the three K110. Indoors I only was doing very careful hovering (after some repairs). One 6G trim flight was going horrible wrong (heavy swash tilt; even 100% DualRate was not enough to hold nick/ail stick against the chosen board drift direction). Hope you'll find a better brushed main motor or has the S2 motor quality increased to 90+ flights constantly? Else this adventure will get quickly expensive with 16.99EUR per motor. I'm just glad that I somehow pulled out of this Nano mess in 2013/14 (too often the CPX board LVC shut off). Too bad that it is too cold now for going outdoors. 15-18°C is better toleratable than only 1-2°C (not degrees Fahreneinheit). The three K110 have some repairs outstanding anyway... Going carbon fibre, alu head and BL is IMHO not the right thing for this Nano. As you said it: Weight matters. ..(...).. Do you use 220mah 45C lipos with the Nano S2? How are the ProTek packs rated? With that spec the genuine Blade Inductrix LVC doesn't kick in too early. Back in 2012/13 I only had used 150-160mah 20-25C lipos (Eflite and one UK brand). Preheating them didn't help much. On the K110 (450-600mah) very well. I even only use the original 1.25 pin connector (PicoBlade, Ultra-Micro) and have not swapped out for JST PH 2.0 (Mcpx style) or GNB27 V2, as this would have voided warranty. The white Walkera plug on the K110 is not the greatest either. So far it is a night and day experience with my 220mah Brainergy 45C lipos compared to before. Maybe should have done this to the Nano back in 2012/13 too.

The board alone is 79,99EUR (mosfets, gyro, safe sensors, etc.). The brushed main motor is 16,99EUR (I bet it hardly will hold ~90 flights; 8-20 or less were more realistic on the NanoCPX. Main frame 11,99EUR. For a plastic swash: 16,99EUR and a plastic main frame: 11,99EUR. You better don't crash. Hopefully some dealers will get some XK parts again incl. EU/DE shops so it gets a bit easier to order without those insane BG shipping prices (each single article includes total shipping costs to Germany). Had found a few China dealers on AliExpress and eBay. As I said, I will not fly this K110 indoors in tight space.

Thanks Thomas. You always reply with a TON of information took me a while to read your post. Thanks for being so thorough.
In my signature you can find my YouTube channel I have some videos there of the Nano S2 and my basement flying. I am able to invert it and train my inverted piro hovers. The ProTek is a 160mAh 25C. I don't know how good it is but it is WAY better than the ones I had which started losing power after a minute or so. Also there was very inconsistent power so even when I had optimal power it was hard to flip because of this inconsistency. So far the Nano is behaving well for what I want. So I think then maybe just the aluminum swash and that's it.

I used the softer Uhu here in Germany to additional secure the white servo sockets on the board.
One socket solder job was not so good. Pulling on the cables generates some force against the servo sockets on the board.. Make sure to press against the socket with a small tool/screwdriver. It may not look that nice if there's glue (not Sekundenkleber) on the board, but it will protect you in frame swaps.

220-160mah=60mah
60x45C=2.7A current If the board shuts off too early, try the slightly bigger lipo with higher 45C rating. So far it sounds this isn't the main issue, not yet.
