tail wag

[dieselcarb]

hi all really not having a good year

I built a new heli all brand new parts and wired it so I got no wire chafing. flew like a beauty on default setup just as the engine (brand new) started changing note and sound like its breaking in nice I got small tail wag when moving fast and a little wind on the side, so knocked gain doew slightly with im prove ment.

next time out a bit of wag nothing major then it got really bad packed up went home wire chafed grrrrrrrr. OK thay chafed on plastic not carbon so silicone em up wrapped em in insulation tape off I go to field.

tinny winny wag (I had set gain back to 30) changed it back to 26% ok againgets through half a tank and bang its wagging well hard checked wires they all look fine and mechanically its sound what have I done to my bird ?

or what has it done toit self

hope that's ok description it did fly nice at first andy from sandy saw it fly as another and from mk club checked it over and it flew nice seeing that nothings been dialde in yet

all the best terry

I would say the tune could be slightly off causing a barely detectable misfire.

[dieselcarb]

tunes well off running in at mo I have remove tail servo and replaced with a different spooled it up seem ok just need to fully test it
cant be arsed right now though as im tired fed up and in a fair bit of pain

but if it turns out to be servo im miffed as all is wrong with it is slight caffing of wire witch ive fixed (that will be 2 align servos dead in 20 flights each) not happy as these are a ton each and last 1 caused me a crash too (gears locked up then released just b4 battery fell out)

cheers for imput I let ya know what happens tomos

p.s the wag is like way too high gain or as I found a long time ago when the signal wire cuts into carbon

[KevDavies]

hmmm ive always had mixed results with Aligns as tail servos. Some been fine and some been just plain rubbish. I tend to stick to BLS251 and JR8900g now. But id say the underlying problem is the tune of your engine, especially if its really rich and 4 stroking

[dw45]

Have you got the distance set as per the user guide for the vortex? as you might have to much mechanical gain.

[dieselcarb]

this servo werk flawlessly for 3-4 gallons of fuel even when it was 4 stroking on 1st gallon I have now stuck my throttle servo in bls 256 seems ok a bit sluggish like it wants more gain but now my new throttle servo that I bought to replace it has just died rendering me grounded yet again poor engine rev its nuts off


proper mad at mo gonna go nick a snout off mrs ..... (I gave up smoking last year ) aaaaaaaaaaarrrrrrrrrrrrrrrrrrrrrgggggggggggggggggg hhhhhhhhhhhhh

sry in 1 of them laugh or cry moods lol

cheers terry

oh got carried away there gain is on 25% at mo and yes it was set up to perfection for the vx1 cheers

[swale]

You may laugh but dont dismiss its the no.1 cause of tail troubles. .......check your boom supports arent moving around/glued properly wiggle the back box whilst holding the back of the helicopter on tbe floor firmly and check carefully

[dieselcarb]

I think its my fbl unit it flew ok ish with futaba servo but I have just re sorted out the align servo and fitted it on throttle. seems to be working perfect but when ya wiggle the collective stick servo spasms out. is this normal? I love flyin don't get me wrong but im about to give it up! haven't had 1 decent flight since trying fbl

[dieselcarb]

hi swale ive had the happen before but just checked and they are as solid as solid gets tail seems sluggish now I have futaba servo but not wagging but ive just blown a brand new hyperion servo I put on throttle so now put an align on throttle

[KevDavies]

if your gain is at 25% it will be sluggish. try and get it over 30% and the tail should be nice and taut

[dieselcarb]

I was gonna kev but throttle servo died and had to go home lol

[raptorheli2]

can you upload video of what it is doing and i'll try to help? it is much easier as everyones idea of wag is different :-) could be pretty much anything causing it so better to start with a video if you have one.

in mean time what are your tail end points at?

also don't be offended, i have seen a LOOOOOT of helis that were "perfect mechanically" that in reality were fit for mixing cement on.

cheers

[swale]

Lol plus can we see a vid

[dieselcarb]

sorry guys been supper busi iv not been out since I put a futaba on tail and a new hyperion on throttle witch died but no wag cant do a vid as ive now removed servo but bust I can describe is when gais too high and u get the tight wag makes loads of noise lol unfortuneately summers running away and I just cant get out will do some testing and I may shove it on just to see if it is servo as I got another coming that I know works cheers guys sorry for late reply

[KevDavies]

no worries dude no need to apologise to us!!

i too have a little wag on my Vortex, but thats defo caused by an engine that wont play ball! Engine removed and spare engine thrown in while I sort no1 engine LOL
