Raptor 30 V2 Goes Flybarless

[Ah Clem]

Darn you, tr911!

I keep looking at this thread-I keep looking at my Raptor...

[tr911]

Well, you are problay flame me but they are Corona DS538MG's

[tr911]

I gotta say tis definately different. I'm trying to setup two new piece, one is the governor and two is the AR7200BX. Don't look like there is anything on the throttle and pitch curve anywhere. are they supose to stay liner?
I read soomething about letting the ar handle it all but heck I dont get any throttle till about halfstick then it's like it goes full throttle.

i don't have any specs on those servos, i'd recommend you drop it back to 50 Hz, if you want to step it up higher, do so one step at a time and keep a feel on them to see if they are getting hot.

keep all throttle/pitch curves 0/50/100 till you get though the setup then you can adjust them as needed in flight.

[tr911]

Will do.. I take it the DS620 set at 333hz is ok..

[KC36330]

yes, 333 Hz and 1520µs on the tail, but if you used them on the swash, 200 Hz.......

[tr911]

Hmmm, in a hover I can see it jerking a little like the gain on something is too high. I went through the parmeter menu and made some changes gonna give it another shot before it gets to dark.

[KC36330]

i was afraid of that.......you need to ditch the velcro strap and use 3M tape, not the stock white stuff (it's too thick and soft. your wire bundle might be inducing vibration too, hard to tell from the pics you posted though.

[tr911]

Yep, you hit the nail right on the head. I'm using velcro under the receiver too. I got some of that double sided 3m tape so I'll atke everything off and stick it with the tape. I also got my wires tied to the front part of the frame. I'll take the loose. Oh, one other thing the blade grip bolts were loose... I loktited and tightened them up good. Have to set it sit over night now so's it will set. Some body is looking out for me cause I think the blade grip bolt was on the last thread(dang). Gonna have to get a bigger battery too.

[KC36330]

FBL uses a lot more battery then a FB setup.

[tr911]

I am officially a member of the FBL club, a Raptor 30 V2. All that is left is tuning the AR7200BX to my needs and buying a larger battery. Here is he end result.

[KC36330]

Looks good!!

[AKPhill]

Really cool
But wait where is the video ?

[tr911]

I did a video but dang it's a pain to get it read for posting. It's not very good either, I jut did it so I could review the reaction of the heli. May be after I get it trimmed up I can do a decent one.

I take it you still have the 32 engine in it? If so how is the power? and fuel consumption? Im thinking about doing it to mine.

[KC36330]

FBL adds about 10% to power because you're not spinning the flybar/washout/etc..

[tr911]

Varacer, I am using the Thunder Tiger .37 engine.

[tr911]

Well, since I changed out the mounting tape it still has a wobble in it and it is random like it is trying to correct it's self. I'm also having to start the high and low needle re-adjustments. I'm starting with the low 1.5 turns and the high at 2. I ran out of daylight. I only get about an hour during the week before it gets dark.

[tr911]

It could be my servos here is a comparison to the Align ds610

[tr911]

Well I think I figured out what my wobbling problem was. Not enough head speed. I think 1800 rpms and above is the key.

I also have another issue that is not in the book. The receiver just kills the throttle channel for apparently no reason and the status ligh starts blinking. Hmmm.. got to figure that one out.
