Hello guys, I am a happy 30 v2 owner, I have an OS 32 SXH.
I am flying inverted, doing flips and rolls. I find the OS 32 SXH bogs while flipping or recovering from being inverted, it's innevitable to loose altitude and climbs are tough, I have to be really careful, I had maybe 1 gallon during the last week flying this way. Butttttt, I crashed in my last flight, I was fling too low and I didn't have enough altitute to go back to normal position and zaz!..
My buddies tell me that I need a 50 size for the way I fly. But I start university in a couple of months, no budget to get a 50 size at least for 1 year (also the parts are more expensive and fuel consumption higher). So I was thinking about keep on training in my raptor 30 v2 and to get an OS 37....
How many more power do you guys think I can get?? is there a big difference?? should I be fine???? I don't want to do any crazy 3d, just to flip, roll and fly inverted but with confidence........
I just walked inside from flying my R30 with an OS 37. Im not rock star either but i can tick tock, roll invert hover (and working on the piro flip) but back to the point, the 37 seems to be holding up great. Im running at 1950 and i only get bogging with some totally extreme pitch changes that are just seeing how hard you can push it. It seems to be a great investment so far and i recommend it.

wow, it's cool to hear that, it sounds it holds great man, I had to reduce my pitch to -8,+8 in order to bog "less" the heli and even like that man, the heli bogs pretty bad in a climbing, also while flipping I loose RPM badly and I have to be fast in order not to loose altitude fast. I would be fine with some extra power.... I think I'll get an OS 37 then to try out, I guess there is nothing wrong with having an extra engine :O)
Do you think I'll feel a big difference if I upgrade from woodies to carbon blades????
I will appreciate if there is more people who give me some opinions about it.... :O)
Has anyone tried both in the same heli and can share the difference???

same your money and get a .50;)

I have some experience here too. In fact i flew a completely stock R30 until 4 months ago. I did only one roll with the woodies so i cant be completely sure, but you will achieve a more responsive and precise heli. IMO the carbons are worth it.

I am satisfied for the level I have, I am still learning aerobatics and inverted, the thing is that with this combo I have, I loose RPM and altitude while flipping and rolling, if I can eliminate that with an OS 37 - hatori I'll be so happy, I am not planning to do any hard 3d in a while.......

Put a weston pipe on that 32 and you willl have a lot more power for harder 3d flying.It would be the cheapest rout for you.I think Ricks still stocks the wesston.

This sounds almost exactly like my situation a year ago. Except I was flying a Century Hawk.
First I put a pipe on the thing. (better).
Then I ended up going with Carbon blades and this made the largest difference. Know why? Not because of the stiffness of carbon blades but because it let me take the headspeed from 1650 up to around 1950 which puts the .32 right at or slightly above the power band.
I had lightened paddles on it too and it was lots of fun (still wished I had the .37 but it was very flyable for my skills). I was doing inverted hovering working on the different orientations and forward inverted flight.
So then finally I started looking at stiffer dampners and all the other goodies associated with a newbee trying 3D flight. AND I bought an OS .37 motor.....all for my hawk.
Anyway, to make a long story short I didn't want to walk upstream and decided to follow the footsteps of so many others and I got a raptor .30.
I now have a raptor 30 with an OS .37, pipe, and fiber blades. Another big help is cyclic mixing to throttle. Everytime you give it alieron or elevator your leaning on motor so that helped too.
All that being said I wouldn't buy a .37 again. I'd go with the .50. It can really snowball fast (motor, conversion kit, maybe better servos) so you have to watch out. But....if your gonna be staying with heli's then you will eventually want a 50. (I've already bought a used .50 and love it)
Do I need it? nope. Can I fully maximize my .30...nope. It's just nice when I do my version of a tic toc (uglier than hell with horrible collective management).
Getting your headspeed up will help massivly. But nothing will make the .32 run like a .37. And once you try a .50 you'll be in love.

Hello, thanks for answering, I appreciate it,
Well, I don't have money to afford a 50 size, I am flying with a 60bucks telebee and If I get a 50 size I would need at least a 401 with digital servo I think. Also, upgrade my servos, get a hyper50, as you said, much better to get a 50 size complet, problem, I don't have the money now, hehe...
For now, I think I'll get an OS 37, I have read I'll feel the difference in comparison with the OS 32 and specially if I get a set of carbon blades! for my flying, I just need a bit more of punch and increase a bit more the head speed. I don't want to do any crazy 3d for now (I think, hehe). I'll try it with my revolution muffler, and then after I'll upgrade to either a muscle pipe or a hatori pipe......

Why not just up your headspeed now and get a set of FunKey composite blades (±$65)? Then the money that you are sitting on now hang on to it until you can get the .50 engine!

yes, I had thought about carbon blades.... do they have to be good brand??? I have seen some ebay for 30 size in about 30dlls. I am using the same blades for my t-rex 450 (obviously smaller) and they are great..... what do you think????

so, do you think these blades are good?????

I have no idea. Blades are the only thing that really frustates me on my nitro heli's. They make a crash cost upwareds of twice as much vs when you crash wood blades. They are just that important.
I've only run Mavrikks and liked them. I hear most like them but they arn't that much cheaper than nicer ones (If I remember correctly). I'd try them first before the .37 since you need to use them anyway. then if the performance isn't where you want it buy the motor then.

Thats not bad flying at all and im glad you posted that video with the stock OS.32 :thumbup:.Im getting a raptor 30V1 with the same motor and I fly the same way you do (flips,invert hovering and rolls) so I think ill be happy with it the way it is for now then i'll get the OS.37 when I have the extra cash :YeaBaby:..

One thing you can try is removing the metal inside the muffler where the header (the part that attaches the muffler to the engine) connects to the muffler. If you look through the header hole inside the Revolution muffler, you'll see that the opening is quite constricted - nearly half of what it could be if you remove the metal. Removing the metal does not affect the strength of the header/muffler joint since you're only removing about 1/4" on all four sides.
When you restrict the exhaust air flow you're reducing the power output of the engine - it's the reason
quarter mile drag racers run open headers when they race then put the street exhaust back on when they're done.
I did this modification to my Revolution muffler and it made quite a difference. You'll have to adjust your
needle settings to compensate for the reduction in air flow.
It's a cheap fix that might get you buy until you can afford a 50.
