RE: Raptor 50 Titan Discussion
thats a sweet titan man. And no my heli did not come with a motor or ESC, I went with a Z-Power Z50A-800 780Kv and a Pheonix 85HV speed controller, with an 8 cell lipo, this motor turnes 4000 kilowatts approx 5 horse power (I think) It has alot of power to burn anyway.
Anyway I love your color sceam I think its cool when people keep it the same throughout the bird. as apposed to blue fins purple bolts and a red canopy... you get the idea.

What is the best way to tune the motor on this heli? Run it with out the mains?

No, DO NOT run the helicopter without the main blades. For Engine tuning visit raptor technique.

RE: Raptor 50 Titan Discussion
Question. With my servos, the Titan came with metal plates that go over the grommets. Should I use these alone, with the brass eyelets that come with the servos or just the brass eyelets? My R30 did not come with these plates so I just had the brass eyelets.
Thanks
Thanks

RE: Raptor 50 Titan Discussion
I have set up all my pitch curves and getting ready for the first flights tomorrow AM.
Are you guys using the DS on your 401's or not? I heard that the 401 in DS mode has been burning up servos. Yes, I am using digis.

ds mode doesn't burn up servos, running too much gain does.
Yes do DS mode.
Don't crank it all the way up till it wags then back off, start with 50 percent and go from there, if it holds leave it alone.

Normal mode A80%
Idle 1 A70%
Idle 2 N70%
Do you agree or disagree with these settings?
I also adjusted the limit to about 85-90% and delay is factory setting at 75%

I didnt see anywhere where you stated what servo you are using with the 401 gyro. Are you using the 9254? If so, you need to set the delay to 0, and the DS switch to on. If you are not using a digital servo on the tail, turn the DS to off and add a little delay. The 401 gyro was designed around the 9254 servo, so it is the perfect match. Therefor, does not need any delay. Delay is mostly used for non digital servo's.
Here is a link to better help you understand.

RE: Raptor 50 Titan Discussion
A=50 is where you want to start.
Run a longer servo arm and get the limit up over 100 to 120, in your case probably move out one hole, think 14 mm or so from center.
For delay set it to 0.
Do a piro and let go hard (if you are comfortable with this) if the tail oscilates before it locks on increase the delay in very small increments till it stops clean. I can't find the specs for that servo but the closest models are all significantly slower than the 9254 so you will probably need some delay.

SPECS: Speed: 0.17 sec/60° at 4.8V

S9254
SPECS: Speed: 0.06 sec/60° @ 4.8V

I misread the factory setting on the pot, it's at zero, not 75
. I will set it to your recommendations on the Tx for now. Thanks.

RE: Raptor 50 Titan Discussion
I got 6 great flights in today, what an awesome heli!!
Only have one problem, the gain on my 401 is at 30% right now and it's still wagging. Other than that it's very smooth and responsive. Is it normal to have low gain and can I go lower?

RE: Raptor 50 Titan Discussion
Once you are below 50%, you are no longer in heading hold mode. Try to set it up to where it is in HH mode (above 50%) at least in idle up. On my gyro, i use to have a problem with it wanting to drift when in a hard climb out or during aerobatics. The fix to this was to increase the linkage ball from 10mm to 14mm out from center on the tail servo. Then, i trashed the futaba gyro tape and bought some 3M double sided outdoor tape. Its a bit thinner than the futaba tape, and stiffer. This made all the difference in the world. My gyro holds rock solid in hard climb outs and aerobatics now with my gain set at 75%.

RE: Raptor 50 Titan Discussion
So I was setting up govener mode on my ESC and I had to stop, what head speed should I be running for a titan? I'm looking for easy hovering and slow stable forward flight. I can dial in my head speed to almost whatever I want, but I dont know what I want. should I go for 1500 rpm's 1600? 1900? 2500? I'm not sure what to start with. I was wondering If someone could give me a starting point, and maybee tell me what the effects will be of raising my head speed. what will I notice between 1500 rpm's and 1900 rpm's?

RE: Raptor 50 Titan Discussion
Assuming you have a gear ratio of 8.5, for a nice stable hover with easy handling, try 1500 rpm. If you are going to be doing a little forward flight, 1500 is ok, but you can try 1600 as well. That will keep things smooth for you. Later on, when you get better, set up your normal mode for 1600rpm, and idle up at 1800 rpm. And when you get really good, try out 2000 rpm in idle up.
1500 rpm is fairly slow on the headspeed, and it doesnt make control inputs as sensitive. When you increase to 1800, 2000 rpm, the faster headspeed makes a big difference in control sensitivity, and rudder control. When the headspeed is up, the tail blades speed up to, giving you more tail authority. 1900-2000 is where the max power is in the engine. You won't bog down as much in tasking manuevers. Don't go too far over 2000rpm. That is 17,000rpm engine speed and you dont want to overrev the engine.
