hi

O.S. .37 with Hatori pipe... If you arent going to upgrade the pipe, dont bother getting a .37 The .37 works best with the appropriate pipe.

Crash-Prone and overcoming it!!!

OS 37 or TT 39

OS 37 also works well with the Toki pipe if on 30% fuel.

O.S. .37
For ALL of the reasons you mentioned in your initial post.

Power, Reliability, Tuning...

There's nothing like the sound of a tortured Stratocaster.

Has anyone said "OS 37" yet? Only way to go. Just put a good muffler on it.

I have a TT39....the power is amazing, OS's are pretty bullet proof however.... my TT has to run a bit rich, but with the MP2 it is pretty pppowerful.

Jamesshadowvlx, I have a TT39 also and love it. You are using a MP2, did you have to use a muffler extension? I have a Century muffler and I have to use a Dubro 1/2" extension to clear the tank.

I have both, OS 37 and TT.39 !

I like the OS.37's power better.

And when installed with the 415 Hatori it gets even better !!!

.

Keep it up...literally

Re: 30 size motor selection OS 37 or TT39pro

Here's my perspective,

I have both, the 39 has a hatori tuned pipe (raptor 30), and the 37 has a hatori muffler (venture 30). The 39 without a doubt has more power than the 37 o.s. Tuning is the same. If you are looking to build more power than your o.s. 32, the gains are not that significant to go with either. Converting your heli to a 50 would be a good progressive step forward. If you were setting up a 30 sized heli, either the 39 or the 37 would be fine, but to replace a 30 sized motor with another doesn't make sense because you'll outgrow it too quickly to justify the cost.

I hope this helps,
Mike (Linear_1)

it does make sense. i am truly just beginning. i have been flying only a shor while. i have realized that with the sim(G3) i tend to fly awesome with the bigger birds. but i have a caliber 30. i was just wondering. i have two cal 30's and was actually thinking of converting one to a 50, since i already have the extended boom, belt and motor mounts for it. ( it came with the package i bought)i am still in the hovering phase and cant seem to feel confident enough in the setup to go much further. i have not been able to get the 32 to run very good or consistant and dont want to have a problem somewhere up in the air. so i was thinking of replacing just not with antoher 32. hope that made sense.

Who keeps moving the ground closer to my heli?

A common complaint with the OS 32, but usually the result of having the low speed needle set too lean to achieve a good idle. If you go about setting the 32 up that way, you are doomed to having an engine that runs poorly, inconsistently, unreliably, and eventually dies lean.

If you can learn to tune the 32 correctly, most other engines will be much simpler to set and maintain,

The 37 runs much better overall, and is easy to get running correctly. The TT39 is reputed to be difficult to set up as the taper on the needles is too abrupt, giving a narrow and hard to find "sweet spot". A common solution is to rework the taper to one that is longer, giving you the ability to get a broader range of tuning so that the setting isn't critical.

You say you haven't been able to progress much past some of the basics as you don't have any confidence in the set up. Learn to tune your engine, or find someone who understands the 32 to help you. Or put the 37 in, put a good, high-volume muffler on it, and go fly.

I don't understand the comment that continually pops up about a 30 sized machine, "you'll soon outgrow it". There's an entire thread here on RR that starts with the premise "why is a 30 size heli too small". I believe that the premise is wrong in that thread. After flying helis of ALL sizes over the past 30 years, there is still plenty of room in this inn for several 30 sized machines (all three Caliber 30s).

The Caliber 30 with the OS 32 properly tuned will take you a long way. The Caliber 30 with an OS37 will take you well into advanced aeerobatics. It's a very capable, light-weight heli.

If you need help setting your 32 up so it will run, try reading my reply in this thread:

http://www.runryder.com/helicopter/t272559p1/

I think it's the ninth post in the thread.

Engine tuning is an acquired art. If you can't get an engine tuned properly, NO size heli will do what you want it to do.

wow, thanks Dkshema, i appreciate the help. i will try these steps when i get home this evening. i agree that the 32 should have ample power to do what i want. my problem is it always appear to be very hot and not want to idle. i did buy the heli used and that may be why i should start at the begining for my own peace of mind.

Who keeps moving the ground closer to my heli?
