Logo 550sx / Goblin 570 belt adjustment

[chrisleematt21]

How do you what the right tension is for the tail drive belt?

How tight is too tight?

Currently I am adjusting the belts on both as I thing they are too loose.

On the G570 if I push on the belt at the heli end with little force I can get it to touch the other side.

On the Logo at the tail end I can do the same.

Wanted some advice how to know when it is adjusted correctly.

On the logo and I am doing it as tight as I can get it atm.

Sounds like they are a little slack,can't comment on goblin but on the logo you want to aim for it to be allowed to get half way to the other part of the belt.

Goblin is marginally less sensitive to having the belt uber-tight as there is more room in the boom. The Logo boom needs the belter tighter to avoid it slapping the inside of the boom under power.

I was told that the goblin needs to be tight enough so that it needs a little bit of force to push them together. Too tight and you can stress bearings

A tip I picked up over on Helifreak for the 570 was to hold the heli (with battery mounted) from the tail case and then tighten it.

Has worked well for me and the tension seems pretty good, and this way the tension will always be set to the same level.

Cool thanks I'll give that one a go.

oh yeah, i also recommend this:
Lynx Heli GOBLIN 500 Tail Upper Case Silver LX0514

as the stock setup allows some rotational movement of the tail, this takes all the guesswork about getting the tail perfectly vertical, my ocd was not allowing it to be slightly off

if you get the stretch kit, this already comes with it. (stretching it is awesome by the way - and cheap at fast lad for the red and sliver one!)
