I suppose it could shorten flight times, but when you punch the throttle, the snappy acceleration and higher speed make you forget about that. I don't notice shorter flight times, so it's likely a small amount. I know that it hovers with a lower throttle setting, so it might be a more efficient motor. I'm just not sure how all that works.

Oh cool, you guys got any video of V915 with new motor flying?

Sorry, My V915 still has the stock motor. I have the F45 motor in my V912.

I haven't shot any video of the V912 since I installed the F45 motor, but there are a few on YouTube.

Price is cheap/ heli looks decent/ stock outside in breeze suffers/ bobbles all over. That said/ little paint to tail cage/ motor upgrade not bad heli. Indoors stock motor is fine. Very sable etc. I think newer flock of noobs are buying cheaper quads. To lame to even fly self stable f/p helis like this. I thought this heli would be a big sucess. scale looks and very stable. Folks ask why not more scale. Simple answer as they don't sell thats why.
Walkera 4f200 LM ,is a beautiful c/p Scale heli. barely a word about it. Cost is not cheap but is a bl shaft drive c/p heli 200 class. The cage tail is made similar to the real bird. Walkera had a whole line of scale birds. Gone for good. This one and another remain. The V915 looks similar on outside except for tail cage. 4f has three balded head. Under the hood different world. That said V915 looks like a real heli and not much more $$ than V912. V912 is just a bigger V911. If you have V911 you will learn nothing with V912.

My V915 got a little bit of time flying indoor the past few months. When I get a calm day I will fly it outside. I really like hovering around with the heli though and flying it scale. Makes my flying skills look much better than they are while flying around a gymnasium.

I also love my V931. I might even buy another one because I love the scale looks and how stable it is to fly. I want to paint a custom fuse for it. The only downside with the V931 is the 3-4 mins flight time and the under powered main motor which bogs when the collective/blades load up.

Indoors heli flys fine. Outside any kind of wind will effect the way it handles.
I would have liked this big time when i first started flying. Looks good and very stable heli. V911 and this would make a new flyer smile. I guess V912 would also but will never know. Problem once you fly c/p's F/p just doesn't do much for you. FBL f/p better. I still fly MSR-X and V200D01 FBL F/P once in awhile.

I've flown FBL and CP helis for a while now, and I still enjoy my V915 and V912 (with Hughes 300 canopy). Blasting around the sky like mad is gobs of fun, but I actually prefer flying in a realistic, scale manner. The limitations of the flight envelope are well outside the way the real ones are flown, so I never hit those limits. I've just ordered another CP heli, and it'll be my "toy" when I want to "play", but these FPs will still be my preferred relaxation helis.

I fly my stock V915 in the wind all the time... It's actually my goto heli when it's too windy for my 130x I can't wait till I burn motor up so I can go brushless or F45 motor. Hell I wanna remove the flybar just to see how it flys lol

Not often but once in awhile fly V911/ V929 quad/ V915. V911/ V929 are almost three years old. Nothing was ever added or replaced. V915 full size TX flys them all. Then fly something like Nano CP-X bl and get real again.

I must be getting old. I fly a CP or FBL heli once in a while to get unreal again.

For me, after flying CP then flying FP it's almost like comparing 3ch coax to a 4ch single blade heli. I like to fly FP for relaxation and scale flying. Then fly CP to get "unreal".
