Glad you are enjoying your heli and the low cost parts. If you ever fancy something a little bit more aggressive but still able to fly like a fixed pitch if you like, have a look at the K110. It's not compatible with the V911S transmitter but it is even more fun, stable, cheap to fix and also very durable.
Missed seeing your awesome vids. I watched your vid on adjusting the Xk 120 over and over...Your an amazing video teacher....Really like reading and hearing about your experience with heli's.
Having a rough week and a comment like that brings a smile to my face regardless. Helping someone else's RC journey or saving a few quid is why I do this so good to know it does help or entertain a little. Thank you for the kind words Todd.
So, you like it then? I have to say, for the money, it does look amazing value. The only criticism I have, is that there doesn't appear to be any way of disabling the self level. Am I right? I suppose it doesn't really matter, seeing as the old one was mechanically stabalised with no way to "turn off" a fly bar.
For circuits outside yeah I do, I think it's a nice step up from the V911 in that regard but tougher to hover on the spot than the original. Quite different but complimentary to the v911. Yup, 6G/self level is constant, curious if binding it with deviation or open tx would allow tweaking of that but not even sure what protocol it uses yet, currently digging. It's where the XK stuff takes the lead with 3G/rate mode, 6G and some models you can set exactly how strong the 6G is plus exact rates and expo etc. All that would have just confused me back when I was flying a V911 though and only dipped my toes in to that world because I wanted to fly inverted so badly.
Nice. But, why not get the k110? Price point? I started with a v977, then a v911 (years ago) because people said flybar was easier to learn. I only had the 977 2 weeks. The 911's flybar was already too restrictive for me after learning the 977 for those two weeks. I gave the 911's I bought as gifts. Nothing wrong with any of them really as long as it gets you in the hobby!
That really depends on the pilot, their skills and a little about budget too as RTF packages are twice the investment regardless of how worthy both you and I feel that is. I absolutely would choose the K110 over the V911S but whether that's suitable for totally new pilots i'm not so confident about - I have to consider some people reading would be picking this as a first heli or have a really tight budget or even zero desire to move onto the relative complexity of collective pitch. There's also the K100 which makes that decision a little tougher and is perhaps even more suitable depending on the pilots skill and where they plan to practice - i'd piroflip that in my tiny living room but don't feel confident doing that with the K110 until I get about twice the space. While the K110 in low rates and 6G it's super easy to fly inside and nail to the spot, the extra RPM over something like the V911 will slice up wallpaper, hurt pets and break stuff instead of providing a stress free learning experience and bounce off stuff. With the mini cp it would also strip servos often bashing it but that doesn't seem to be the case with the K100 and K110 so much less of a concern. If someone was capable of basic hover with control, there's no better heli than the K110 to progress further in my experience, but that's more a question about FP vs CP and i'd want to know more about the pilots and skills plus where they plan to fly too to be able to recommend a specific heli. Just the extra RPM can be quite intimidating if basic orientation is not confident and some people take minutes for this, some people takes months. Learning to hit TH instead of throttling down can only really be learned easily if hovering doesn't take 100% brain capacity It's a different class of heli and feels more appropriate to compare with other FP in regards to a review although I have considered doing a video covering the finer points of picking the right heli for current skills and goals and it's easy to predict the K110 would be high up there.
Drop of glue around the tail rotor housing & motor, because it will slide out & dislodge cables if tail crashed but, a vast improvement over its predecessor 911's.
FBL and digital servos 20 years ago? I don't think we had much past coax back then. There was a micro heli before the Century Hummingbird in 2004? I remember the Xeida 9968 popping up around 2009 ish but that was just a flybar FP. It is amazing what £50 will get you these days though, anyone learning on a K110 for example has a very easy ride compared to just 10 years prior. Never been a better time to get into helis
My budget is about 60 to 70 pound and I would like to fly in or out doors.I have been flying quadcopters but never a heli and I want to try something different.
@@deandaniels203 Ok, i'd probably have a look at the K110. It's going to be tough to do much inside but hover practice unless you have tons of space but it's pretty capable outside too providing you can find a spot out of heavy wind. You can of course tame it down via the transmitter. If you can hover already it's a perfect first collective pitch heli that will fly better than any fixed pitch bird. Still get self level if needed and enough power for inverted and more. If you use throttle hold and let it fall rather than keeping power on in crashes it's pretty durable. Currently just a hair under your max budget for the RTF with X6 transmitter but absolutely worth considering. Cheaper if you have any multi protocol options available to you. Worth keeping a set of spare main shaft bearings as spares and maybe some skids and a tail blade but that's about it. You get a spare main gear and blades in the box. www.banggood.com/search/k110.html?p=UI14032168777201508N Here's my playlist for the K110 so far, more to follow.th-cam.com/video/wdkIrHOERK8/w-d-xo.html
I don't know of any micro heli's that don't share parts with others, especially of the same brand. It's just good design to keep costs down normally. I can't say I know the V930 FP but think the protocol may be different. I don't fly many fixed pitch any more since a CP is so much more capable and stable plus now they come with 6G, tend to fly better basic circuits too. K110 for example, way better all round, unless it's given to a very new pilot in which case FP can sometimes be more suitable. Certainly easier to hover on the spot inside than the V911S
So true, i own the v911s, 12, 30 and the 50 all pretty good for what they are although waiting for parts from china is a huge pain in the a$$. I don't buy overseas helicopters anymore i buy strictly from american companies such as Horizon Hobby and use Hobby grade Transmitters, So all i fly anymore is Collective Pitch, much more rewarding! Yes the protocol for the WL v930 is different because it has a brushless receiver board much more powerful and stable outside in the wind. The toy grade WL toys transmitters will interchange across different WL models that are coreless including the F949 Cessna 182 but they won't connect to the brushless boards, they have to use their own protocol specific radios, and i say this for people who do not know this, just for a quick mention the Jumper T12 works good with overseas stuff as well as the Dsm2 / Dsmx protocols. Happy flying..
@@donaldtrump2078 Man if I could get a stock blade to fly anywhere near as well as a stock XK i'd be down with that but they always seem to need same money again on upgrades to do so.

@@aerialcombat The K110 is a great 3D trainer, forces collective management while still having enough power and precision to fly well.

Hi do u have any idea if this heli can be flown with the other WL Toys 4ch transmitter? I already have one from V912, i’m planning to get the V911S BNF version. Plus i don’t really like the standard transmitter from V911 and V911S.
It's not possible as far as I am aware, it will only bind with the stock TX. The V911S uses a different protocol from the other WLToys models and I think there is some extra mixing happening in the FC also. Really odd decision from WLtoys on that one, I have no explanation why they did that. I also don't think there any open TX or Deviation models for it either.
@@blacksukhoi Hey blacksukoi, I'm told this is now supported on deviation. I don't have any specific links for you but i'll pin this along with David's post above so hopefully it will help others.
That would be a firm no. They use their own protocol. Apparently it has been reverse engineered so if you have a flysky transmitter with a 4 in 1 module, that might something worth looking at. Not sure if deviation or open TX options as not looked into it, just what others have told me.
I have no experience with the Blade 70 or many fixed pitch helis at all past the V911 and V911S. Both of those are pleasantly durable and unless crashing under full power repeatedly, rarely need repairs. The V911 is far superior of the two for flying inside and hovering and crashed the life out of it daily learning to fly - very durable. The V911S is a much better alternative for circuits outside and I ave it away so can't speak on durability past an educated guess that it comes close to the same performance. Most 1s helis will be pretty durable unless there's some kind of flaw in parts design as there's just not enough weight and rpm to do much damage compared to say a 2s heli from any manufacturer. It's perhaps worth considering a 1s collective pitch heli if you have basic hovering and or circuits down. Any modern one from Blade will give you self levelling and fly better than a fixed pitch heli plus there's room to grow into flips and inverted flight. I really like the K110 personally as it's super durable, affordable, cheap to fix, flies superb with great tail performance and has a brushless main motor. Here's some bashing with it. th-cam.com/video/pQEgNyA9BMc/w-d-xo.html&ab_channel=MicroRCFiend
I am not sure that is possible with stock transmitter. Mode 3 you could just swap gimbals over internally but mode 1 is mix of only 1 axis on each gimbal compared to mode 2.
