Dear All,
I am a freshman.
I am thinking to buy a Caliber 30, but I am confused why don't you use S 3003 servos for Heli operation, as I own a RC submarine Robbe Seawolf and S130 torpedo boat, I used to install S3003, may I ask why this is rare to install S3003 servo to Helis? How many servos do I need for Caliber 30? Also, how fast is a Caliber 30 if I install an OS 32 SX-H engine?
Many thanks,
Els

Not sure about the servo series to your question, but youll need 5 servos. Caliber will do nicely for you as a first ship and beyond. You wont need anything more than the OS32 for power

elsyau , S3003 servos can and have been used in ic helicopters, They are a cheep non BB servo.Personaly for a 30 sized ship I wouldn't use anything less than a 3001.Idealy you will need 4 of these . Then you would be better to get the best gyro&tailservo combo you can afford.
At this time when your learning to fly you will need power and not speed and yes the os32 and os 37 have more that enough.

OS 32 is perfect. I flew this motor in the Caliber 30. One of the nicest helis I owned.

Best Regards, Dario

elsyau,

Since your a Lawyer I would assume money is not the issue. If money is not a great concern use three S9252's for EMS, one S3001 (min.) for throttle and a GY401 with S9254 for the tail. As you progress the advantages of the S9252 will become more important. in EMS accurate swash movement requires all three to move in sync. This is something that the S3003 or S3001 can not provide. I know this from experience. I started out with a caliber 30 with S3001's. I would also suggest an OS 37 or TT39 for a powerplant. There was a few times when more power could have avoided my heli from hitting the ground. Collective management is a important skill to learn but I feel that it is better to have close calls rather than a trip to the hobby store. The only significant price you will pay with these motors is fuel economy.

I’ll 2nd or 3rd the OS 37. It’s got more power that any other 30 size engine with OS reliability. Don’t use the stock muffler though. It’s fine for the 32 but not big enough for the 37. For the servos I’ll been using the JR DS811s for about 2 years now. They’ve been flawless in operation and relatively inexpensive. Go with the GY401and S9254 for the tail. IMHO

Many many many thanks for your help and comments!
Now, I have seen a bright light throughout the dark.
However, may I ask some more questions?
Is it absoluely to purchase a 6 channel radio? As I have got a 4-channel for my RC submarine, but seems that is it not suitable for Heli, right?
Also, why do we use digital servos instead of a cheap FutabaS3003?
Moreover, I have done some research for the engines, there is only 0.2bhp in difference between OS32 and OS37, and is it worth to pay more for 0.2bhp? Suppose my Porsche 911 is 231bhp, but it seems there is no much difference compare with my son's Porsche 993 (280bhp), so back to the topic, what do you think about the 0.2bhp in our RC helis? Seems that a power to the mass question?
Please reply,
elsyau

4 channel is no good. You need at least 5 and preferably more!

You need:

3 Channels for cyclic / collective servos
1 Channel for tail rotor servo
1 Channel for throttle servo (see we're up to 5 already!)
1 Channel for Gyro sensitivity
and later on:

1 channel for Governor RPM selection
1 channel for governor on/off


You don't need fast digital servos on a Caliber but the S3003 is not recommended for helis, not precise or powerful enough -

Yes, the power difference between the 32 and 37 is amazing. The 37 has a lot more power. I haven’t even seen the full difference because I’m still flying the stock muffler, but that will be remedied in a couple weeks. I’ve had 2 OS 32s and my 37 blows the doors off them.

elsyau,

0.2 HP doesnt sound like a lot, but you have to look at the percent gain. In this case its 17%. That is a large hp gain.

As far as radios, you need to get a radio designed for helicopters. They have function like CCMP mixing that no other radio will have.

I would recommend you don't get a 6 channel radio to start out with. They have very limited heli capacity in general and you will soon be wanting to upgrade, taking another lump out of your hard-earned.The Futaba 9C is a good radio which will not hold back your progress and has all the heli features you could want in the foreseeable future.

I have hands-on experience of this subject as I tried to start with a 6 channel and soon had to upgrade to a 9 channel to keep on progressing. It just aint worth the initial saving

I agree with WMac.

Started off with a 7 channel and upgraded to a 10 channel - although a 9 would have done

If you can afford to, go with the best electronics you can - you will use these as you upgrade rather than having to buy twice.

For the radio, look into the new JR 9303. I got to play around with it the other day and it’s very nice. I fly the 8103 and it’s a great radio, it’s just a little out dated with the 9303 out now.

Don't use s3003. Futaba even warns you about it. S3003 is direct drive, that means the potentiometer is directly coupled to the gears. Vibrations can damage the pot very easily.

The Futaba says that the S3003 is an updated replacement for the S148. It has no BB in the top case but could easily be coverted for BB with a kit from Futaba.

The S3003 wouldn't be my first choice but should work fine. It is not listed on the Futaba Spreadsheet for Heli application but it is listed for cars. IMHO, if it will survive in a car it should be OK for Helis. .

I really wouldn't recommend the S3003. I'm sure I've seen a warning from Futaba not to use it in helis somewhere or other. Just splash out the extra $ or so for the S3001

Many thanks for all of your help! Thanks!
S3001 seems to be good choice, if I buy four S3001 servos and one digital servo( for tail rotor function), do you think it is the best combination for beginners?
Would you please suggest some "best buy" plan for me?
Please write down your comments, thank you!
