Important: Get your gearmesh correct!
Getting Main/Tail gearmesh correct is a pain in the.. specially with plastic frames if you got it a bit off the first time, you have dents in the plastic, when you tighten the bolts, they tend to move back in the previous position.

And you also need to make sure mesh is good, both up and down (angle of the pinion) which can be a bit tricky as well.

However, take your time, get it right, its worth it.

Why?

Numbers speak for them self.

Bad mesh:
6 minute flight
2900 mah used.

Perfect mesh:
6 minute flight
2500 mah used.
10-20% power increase.

I basically got one more flight minute and a very good power increase, very noticable on the heli.

Any tips on knowing it's right?

I assume you're talking about the tail?

Thanks

I do not know Mels way but here is what I have found to work.....
I use a piece of paper, fold it once, put it between the pinion and main gear, push together hard as you can and tighten, perfect. Now if it is a very small pinion same rule only do not fold the piece of paper. On mod.7 pinion anything less than 11 tooth you do not use paper at all and has to be all by eye, you then have to have it super tight to avoid prematurly wearing the main gear.

I use the same method as OICU812, its the absolut easiest way.
Afterwards you doublecheck it by holding maingear, and turning tailblades forth and back, you should have little movement without maingear is moving at all, just a bit, same thing applies for motor.
But as OICU812 states, if you are using small pinion with 0.7 mod main gear, you need it to be tight.

With the plastic frames, as I stated its very easy to get dents in the plastic, if you get them in the wrong spot it can be hard to adjust the mesh, the bolts will fall back into the dents, what I did was I took a washer that was too big for it to fit, then I removed a bit from the top and bottom, so I got a really long washer, re-adjusted the mesh using paper, and then tightened the bolts again.

I would guess belt tension could have an effect on how much power it drains too?

Thats one thing I like with the Tangos, they rotate so freely without any coging - makes it possible to feel the amount of resistance in the tail.

Good idea on the washer

Yea the tangos even auto better, and I am not kidding. The tangos gave me the best autos on Logos, simply because of the no resistance and the ability to almost help along the rotation. I do dislike outrunners and orks for this reason. BTW Tango has just developed a 45-09 and is working on bigger wind series to compete more directly with the new Hackers and NEUs', very interesting indeed....Once upon a time there were Nitros, flybars and frequency pins...
