ok, i can not get the tail to perform on the smaller electrics like i can on my nitros, why dose it seem harder to get a small electric tail to hold and piro nicely compared to a nitro. i have even taken a 770 off my nitro and put it on the electric, set it up, and cant get it to hold like the nitro. on the gaui 200 in idle up when i pitch pump the nose goes left, barely loading the motor up will make the tail break loose. im not new to setting up helis or 3d so i dont know why electrics seem harder. what makes it frustrating is that i have no problems with the tail on my nitros.

Nitro would be harder if anything due to the vibration. Sounds like you just need to lengthen the horn on your tail servo on the little electric guy. Either that or get a faster servo. Don't know what you're running now.

ive tried different lengths, and the servo speed is .08. im using a 401 gyro for the tail. it has been a lot easier seting up the gyro on the trex 600 compared to the small electrics i have owned.

what do you have for your endpoints for the rudder? it held much better when i put em @ 140 either side, seemed to hold it with more collective.

ten grand in helis and all i can do is hover

Smaller helicopters are probably harder to setup, because they're harder to fly. Anything wrong out of balance will make a tons of difference.

A 600 will always fly better than a 450 and if you want a consistant piro you`re barking up the wrong tree with a 401.

You need finer resolution on the smaller helicopter...

also remember that the closer any of your electronics(BEC, ESC) are to a gyro there could be a small amount of interference

I was recently at a fun fly when Curtis Youngblood was discussing this phenomenon. He was discussing how his Mini G is made for smaller aircraft and is setup to filter electronic interference. The Solid G was designed for larger aircraft as electronic interference is usually not an issue since the components are more spread apart. He stated that the Solid G is designed to filter out vibrations. That is why the Solid G is not really recommend for smaller helis and the Mini G is not recommend for anything over a 50 size nitro.

So, long story short...is your BEC or ESC too close to your gyro??? This might be an issue also.

Well last time I talked to Curtis and asked him about the Mini he said it works great on any size heli period.
they were flying it on 700s perfectly.

my end points are at 140, i think it is just my set up, i guess i need to work on it. but i have had 2 rex 450's, a blade 400, and now the gaui 200 and they all have been harder to get the gyro set-up. i think that some of the problem has to do with the reduction in power and voltage. on nitros pretty much the voltage stays the same, but with these you got one battery doing a lot more work. it seems to yaw more when the motor bogs, then when a lot of tourque is applied. there is plenty of pitch in the tail to fight the tourqe, so why would the gyro have such a hard time keeping it straight compared to the nitro where you take 5 min to set it up and bang on it with no problems. i do see the side with the electrical interference, but the problem i have had has been a very consistant problem with all of my smaller electrics unitl finally i get the right combo to work. i got the tail to lock ok on the blade 400 but tourqe changes during piro manuves made it piro inconsistent. example would be piroing outside loops, it was fine untill the backside of the loop then it would start to sling around. my 600 n never did this with the same gyro. on the nitro i really have to load up the head bad, puposely to get the tail to start to drift, but not much for the little guys. but then bert flies his 200, im like wtf! so obviously it is my set up, i wish i knew what he knew. he is using a 401 maybe i need the 3154, but the servo i have should be fine. sheesh

yes a 600 will fly better, but we are talking about set up nitro vs electric. i know a 401 dose not piro great, i was talking about it simply holding better. when referring to piro i was saying that a gyro on a nitro will piro great (770 gyro on trex 600n) but putting the same gyro on a small electric (blade 400) all the sudden it wont piro as good.

I've noticed that piro maneuvers aren't as nice on the 450 as well. I'm guessing it's just because those tiny little tail blades don't have as much authority to keep the tail in place when you load up the head.

Of vastly different sizes.

ya, but it just dose not make since to me that the gyro would act different. a trex 450 is a scaled down 600, so why would the gyro act so different? i had 2 600 electrics one belt one tt, and had no trouble with the gyro, but make it small and now things change.
