hovers okay then drifts.. help/advice/abuse..

[Disc]

Guys,

T-rex 500 okay so new hi-tec servos HS-5245 MG x3 of all seem to be working spot on no issues no slop etc.

I can get the T-rex to say hover spot on land then return to the hover and it wants to then drift left or right. Nothing's changed wind is minimal and its quite harsh left or right.

Next get it to hover spot on again fly around 1 half circuit appears to track straight in flight return to hover and it drifts left right again quite bad ?

Why could it start to drift all of a sudden from stable hover land and lift off to same hover ? or fly around and return to hover ?

Ideas please need to get it flying right before installing into the Airwolf body.

just a guess

Could be those servos Disc.
Mine never go back to the same centre twice!
Futaba 9650's are the way to go. The Hitecs are never gonna make it fly right.

Do you remember i had the same problem with mine with the same servos? 9650 or ds 520's sorted mine out. IMO those hitecs are crap. try the alighn ones, you wont be dissapointed, even shane liked throwing my 500 through its paces with them on

Sorted mine out in a flash.

hitec servos suck, they are ok off load but when you load them a little they will shift their position giving exactly the symtom your seeing.

ive heard lots of horror stories now about the hitecs not re-centring properly. Ive had 9650's on mine from day one and its always been spot on...

okay just strange how it flys okay then won't hover right.

So I am now happy to know the issue

Now I've just bought 3 servos that need replacing stunning

Yea but some people rave about the hi-tecs and then some don't....

should of got the aligns or futaba's

I must have a good set. Seems to fly straight and be able to hover. Never had any problems with the HiTecs and they have been through a crash too. That normally sorts the men from the boys

Ah see they are okay...

Marc u raved to me about hitecs, seriously, try the align ones, there cheeper and faster than the 9650's and metal geared too.

It could possibly be just one duff servo causing your problem Mark.

I'd try loading them with finger pressure and see if one lets go...
