I may just reinstall the stock for now and see if it'll correct the servo moving off center, also wanted to THANK YOU FOR YOUR SERVICE TO THIS COUNTRY, THE UNITED STATES OF AMERICA ! I am a quick learner, and eventually I'll figure out what is going on, I sure love this hobby ! Thanks Again Sir !
Very good information on a very good mod! The GY401/3400 combo will dramatically improve this heli's performance capabilities. He's using the ds285 servos which will also improve this bird. If you use a higher quality battery (2200Mah/20C+) and stiffer blades (FRP, Carbons) you will have an amazing 3D performance machine. Don't forget to practice with your simulator! Do it 100 times there before ever trying things in real life. The sim will pay for itself in parts within the first month.
Great videos. My eflight gyro finally went and i put the 401 on and the s9257 servo on and it is amazing. Better than the eflight one. Thanks for the help. Keep them coming...
hey sokal great video i bought a blade 450 tail was really out of wack, went step by step on video and now tail rotor is working GREAT! thanks and keep up the good work!
i had the 401 and the jr 3400g did create a lil more demand on the system so i put BEC in to let the esc deal with motor only. the castle 35A is my best recomendation it will do well with stock motor and give room for later upgrades. and thanks
@toddwadefindlay1 adjust by moving the servo up or down the boom to get that lil amount of tail pitch out or adj in servo control rod a 1/2 turn at a time
just make sure subtrimand trim is center and set the gyro gain rate to 45% or so this will center the servo just besure not to move the heli to much as the gyro will stil compensate but not will use the center of the gyro range as it return point
The reason I asked about Rate mode on the 110 gyro is because in your vid U say that 1 must be in rate mode in order to center the tail servo- correct? so I guess my question should have been ... what are the proper steps to center the stock servo so that I can 90 degree the arm. Thanx again. Appreciate all of your help
Hi sokal, Video was a great help. everything went perfect except I had to drop the gain to about 57 to stop the tail wagging?! And after half a battery the ESC went pop. I think its just a dud stock ESC not sure if the 401 and digital tail servo would put that much extra demand on the ESC. Would you recommend upgrading the ESC?cheers
it all depends with a constant head speed the gyro has to work less than if it was in normal but i keep mine set to 70-72 i never fly in normal sounds to be like the belt was skipping with the added rpm jump if belt is too loose it will skip
@nwjt The gyro obviously costs less than the heli (both new) and you can buy a copy of 401 for $14 - dealextreme .20020 The stock gyro would work if only it didn't have that huge temp drift! Revo mixing is poor and might only be good with almost constant rotor speeds which I am not really going for.
just install make sure you keep the gyro set to normal not digital make sure slider moves opposit of stick input (reverse in TX) and make sure gyro moves slider opposit of the tail movement (reverse on gyro) raise gyro gain till wag starts then lower .5-1 %
with the JR285,3400g and 401 iv ran it that way for 9 months before i bought a BEC never had any issuse with this setup now iv saw a trend in the HS65 servos with the 401 and 3400 seems the HS servos suck more amps than the digital JR servos now thats just the trend iv seen some claim to have no issues
if your in heading hold mode than thats normal rate mode with about 45% gain it will center nicly with out creeping if gyro reverse settingin the TX is N then heading hold mode is 51-100% gain 51% is lowest rate mode is 49-0% 49% being the lowest
great stuff ! However, i cant seem to find a 3400G on this side of the pond for love nor money, i can get a 3500G for around 80 of your bucks , would this be a good choice ?
Sokal - thanx for the vid. I have a 110 stock gyro and I cant seem to place it in rate mode. I have my sensitivity below 50 in 1 setting and above 50 in 0 setting but when I flip the switch - it stays in head holding mode (the light stays on ) Any suggestions? Thanks again
whats the best way to deal with that pile of wire that the gy401 gives? i have a beam and there's really not a good place to put it in a bundle, very easy to see through frame, opposed to the b400.
Been going over this video number of times. Have 3500G/401. Been causing problems. ended up R gyro in reverse on radio. now servo works fine, but in HH light does not come on? light off in regular mode at setting of 49.0 on gyro. Any ideas, you can send a PM. Maybe I need to take helicopter to VA Beach for a vacation. LOL (they will be going to sun FL soon tho!)
i just bought a used feda dragonfly and when i give it throttle it spins to the counter clockwise i have the trim alway to the right also to prevent it but its not enough it still spins. is anything wrong or am i doin something wrong?
Hi, i have a problem w. my blade 400 and i hope you could help me. Basically what hhappens is, everything is working good on my heli it initializes and all. Then after a few seconds my tail servo goes all the way in and jams. then the servo starts to heat up and I cant control it at all.
sokal11, First, are you deployed, hate to ask question if you have other stuff going on. Ok, 6v? v would be from receiver, so is 6v possible, not sure I understand this. In HH is the servo suppose to self center, cause if I set R for rudder in reverse then it appears to work fine, but no light in HH? This is a shell game, try to find under what shell everything works together. LOL
Hi, So I finally had the chance to change out the main shaft on my B 400, today, I also decided to change out the stock gyro to the GY 401, and continue to use the stock gyro servo, but can't seem to keep the servo centered, after adjusting tail limits, a few seconds later I see the servo horn moving in the direction of the tail rotor, am I missing a step here ? or I am making adjustments iradically, I sure could use your help here please ?
Wow haven’t flown my bird in for ever. I’m glad my videos still help. I do remember the stock gyro will give a little issue as it’s not digital. But if I remember correctly sounds like it’s hunting. Possibly change the gain down a bit
You have a gyro that cost as much as the heli? Man.. The stock gyro is good enough and a good pilot can fly without a gyro. Just use some revo mixing and you're good. People are crazy!

hey sokal great video i bought a blade 450 tail was really out of wack, went step by step on video and now tail rotor is working GREAT! thanks and keep up the good work!
Hey Sokal bought some carbon fiber rotor blades, new monster foam tape for the 401 and wala perfect tail hold. Thanks for the vids.
i had the 401 and the jr 3400g did create a lil more demand on the system so i put BEC in to let the esc deal with motor only. the castle 35A is my best recomendation it will do well with stock motor and give room for later upgrades. and thanks
Great videos, couldn't have set it up without your help. Thanks a million!
the servo is designed for the tail rotor application very strong and fast
i do recomend it and worth the price
the 290g is a tail spacific servo and is about $37 and is a perfect upgrade from stock. its just a watered down 3400/3500g
@toddwadefindlay1 adjust by moving the servo up or down the boom to get that lil amount of tail pitch out or adj in servo control rod a 1/2 turn at a time
just make sure subtrimand trim is center
and set the gyro gain rate to 45% or so this will center the servo just besure not to move the heli to much as the gyro will stil compensate but not will use the center of the gyro range as it return point
yes same input as the stock
and works well
The reason I asked about Rate mode on the 110 gyro is because in your vid U say that 1 must be in rate mode in order to center the tail servo- correct? so I guess my question should have been ... what are the proper steps to center the stock servo so that I can 90 degree the arm. Thanx again. Appreciate all of your help
yes i can fly with out the gyro but sure makes its easier when demanding torque on the main rotor system to so tic tocs and knife edge
Thank you for your help i apprecaite it and what should i use to shave out the frame
for the g110 the light will stay on
how you will know if your in rate is that the tail slider will return to center when you release the rudder stick
make sure your not running 6v with the 3500g
but check your gyro direction in the reverse menu should be N anything a bove 51 is HH mode
Hi sokal,

I think its just a dud stock ESC not sure if the 401 and digital tail servo would put that much extra demand on the ESC. Would you recommend upgrading the ESC?cheers
I need to follow your procedure here, is what I need to do, very good tutorial is it socal or sokal ?
it all depends
with a constant head speed the gyro has to work less than if it was in normal
but i keep mine set to 70-72 i never fly in normal
sounds to be like the belt was skipping
with the added rpm jump if belt is too loose it will skip
@nwjt The gyro obviously costs less than the heli (both new) and you can buy a copy of 401 for $14 - dealextreme .20020
The stock gyro would work if only it didn't have that huge temp drift!
Revo mixing is poor and might only be good with almost constant rotor speeds which I am not really going for.
well hey thanks friend not sure what a yank is
but thanks for your input
just install make sure you keep the gyro set to normal not digital
make sure slider moves opposit of stick input (reverse in TX)
and make sure gyro moves slider opposit of the tail movement (reverse on gyro)
raise gyro gain till wag starts then lower .5-1 %
with the JR285,3400g and 401
iv ran it that way for 9 months before i bought a BEC
never had any issuse with this setup
now iv saw a trend in the HS65 servos with the 401 and 3400 seems the HS servos suck more amps than the digital JR servos
now thats just the trend iv seen some claim to have no issues
good instructional video
if your in heading hold mode than thats normal
rate mode with about 45% gain it will center nicly with out creeping
if gyro reverse settingin the TX is N then heading hold mode is 51-100% gain
51% is lowest
rate mode is 49-0%
49% being the lowest
well that servo is not a tail specific but is good enough for the 400
check belt tention and gain
great stuff ! However, i cant seem to find a 3400G on this side of the pond for love nor money, i can get a 3500G for around 80 of your bucks , would this be a good choice ?
not a prob the jamie guy is quite a rc hobbyest wish i could help
Sokal - thanx for the vid. I have a 110 stock gyro and I cant seem to place it in rate mode. I have my sensitivity below 50 in 1 setting and above 50 in 0 setting but when I flip the switch - it stays in head holding mode (the light stays on ) Any suggestions? Thanks again
sounds like your belt is skipping or the gain setting is to low or slider is sticking
what tail servo are you useing?
whats the best way to deal with that pile of wire that the gy401 gives?
i have a beam and there's really not a good place to put it in a bundle, very easy to see through frame, opposed to the b400.
Been going over this video number of times. Have 3500G/401. Been causing problems. ended up R gyro in reverse on radio. now servo works fine, but in HH light does not come on? light off in regular mode at setting of 49.0 on gyro. Any ideas, you can send a PM. Maybe I need to take helicopter to VA Beach for a vacation. LOL (they will be going to sun FL soon tho!)
some say 3400g holds better
but i dont think they differ that much
PS I was joking about the no gyro, but its crazy what it costs to make this thing fly decent.
i just bought a used feda dragonfly and when i give it throttle it spins to the counter clockwise i have the trim alway to the right also to prevent it but its not enough it still spins. is anything wrong or am i doin something wrong?

what servo and gyro are you using
part 2 in vid response
do you know how the 3400g compares to the s9257?
You have a gyro that cost as much as the heli? Man.. The stock gyro is good enough and a good pilot can fly without a gyro. Just use some revo mixing and you're good.
People are crazy!
a file or a hobby knife its really not much
just enough for the servo to slide in with ease
Oopsl left out gyro in my sentence Lol !
Ignore to goobers Sokal! They are all over the place. lol
