Status: offline 		Just my preferences, but-

- use the 38T tail pulley if you're going over 2600 or 2700 RPM. use the 41 for control at lower head speeds. At higher head speeds the tail can come apart on the 41.
- If you're going over 2800 don't use the 350s- go down to 325s or 315s. I don't trust the little teeny head parts with the long blades at high speeds.
- and, ... this may be a bit excessive, but with the prices of spares, it was cheaper for me to order another complete kit for spares. If you're crashing, it's awfully convenient.

Cheers .

Status: offline 		hmmm. that makes sense Os. my tail shake was more evident when i'm using the 41t. it was better with the 39t. dang it now i have to put the 39t back in. i hate lining up the one way bearing hole with the main gear and jesus bolt.

i had to dial it down on the throttle curve to stop the wag. i couldnt figure it out cause everything was running smooth with barely any vibrations. but when at lower headspeed the wag would go away. Thanks for the tip OS.

Reassembling the gear to the main is a textbook PITA . FWIW, I've noticed that the GY401s get freaked if they have too much tail response. It's a balance like all the rest .

Status: offline 		Yup OS.. there are some parts that if you order a few of them is equal to a new mars480 kit.. crashing really bad is very imminent to me, if that comes i would probably get me a new kit... i broke my training gear this afternoon landing hard (that's on a soft grass ) i'm just doing 5' hovers right now and my throttle would only be at 60% ... yes longer blades is kinda scary... i might just go back to 340s or even 325s when i'm ready to use some of my throttle power.. as far as pinion, u guys are right, i might put in the 11t tonight ..

Status: offline 		i am doing a little bit better hovering the mars. it was a little bit windy earlier this afternoon but i went out and tried my luck, thats where i drifted very far and decided to throttle down (broke the training gear)... on a calm day with barely no wind, i can hover the mars to stay in a 15 ft square area.. very slow improvements but i'm willing to take my time and learn. i guess the vibrations on the tail is normal.. i checked, rechecked and triple checked and still i can't get rid of the vibration. it's not too much but i wish it was perfect

Status: offline 		You just need to have the airframe big enough for the blades and back off the head speed a bit. It will be more responsive to collective, but that's the reason for the bigger blades . They won't make it better for you to learn to hover, though. If that's where you are, go pick up a set of the Align 325 FG (fiberglass) blades. They're smooth enough to not put a lot of load on the motor, but flexy enough to tame the cyclic a bit and make it easier for you to get used to it. Don't get ahead of yourself, man, no matter what anyone else is doing. That just costs money and slows you down learning.

Status: offline 		thanks for the good advice.. i'm flying my next pack with a 11t pinion for the motor and 325 fg aligns.. i have a set of gazaur 325s, would that be enough for now?

i am also practicing with the belt cp and i was hovering it pretty good earlier today.. i can tell my mars is much more stable.. u think i ought to practice more on a smaller heli and fly the mars after i get a little bit better on my skills?

Status: offline 		Most of us have a beater heli and a good one. The beater has to be capable of the least of the maneuvers and capable of doing the harder stuff you're trying to learn. From what you've described, the Belt isn't a bad beater for you- it's easy to fix (compared to the Gazaur) and it's a lot easier to fly if it's set up well. The Gaz is a bit of a boutique heli and though it's a luv to fly, it isn't until you have the basic skills. I'd suggest spending most of your time on the Belt for new things- it's cheaper to fix . Better still, get a good sim like RealFlight or Phoenix, and learn your new maneuvers there where they don't cost anything when you crash, then work them out on the Belt, and then try them on the Gazaur. The best place to learn new things is on a simulator first, then on a cheap heli, and only after you've gotten it down, on a nice heli like the Gaz.

Your blade and pinion choices sound good. The main thing is to keep under 15g blades if you're going up in head speed. Most 325s will be fine on 11T- that's why I said it the way I did .

Status: offline 		Time for a bit of an upgrade on mine. I initially put it together with HS-55s on the swash and an S3154 on the tail, then changed to S3154s on the swash as well. I liked the 3154s, but they were slurping power like there was no tomorrow. I decided to order a Castle BEC to handle the load, but then decided what the heck and ordered a set of S3156s along with it. Some more tinkering to do, but I've already replaced the tail with a 9650, so I'll program the BEC for 6V, put in the new swash servos, and then we'll see how it goes.

The Gaz is good now, but seems like it could be a lot better with more power from the servos. This should be a more robust setup all around, so let's see what happens....

Status: offline 		hovered my mars this morning with Mavrikk cf 325mm blades i picked up from the LHS .. it was very stable and responsive enough so i can make quick cyclic corrections doing hover... never hovered this good before.. i'm at 12t pinion and i'm liking it better than the 13.. I'm happy with my improvements

Sounds nice, man. The Mavrikk blades aren't the most expensive, but people get a lot of good use out of them on glow helis- I expect they're just as good on 325s . Backing off the insane head speeds the mfrs seem to expect us to want is a good step forward too!

Status: offline 		my first pack this morning went good.. the mars hovered above my head resulting to lost of orientation.. throttled down immediately and the mars landed hard which i thought the skid broke by the looks of it... the skid actually came apart clean , all i had to do is pop the skid back in its place and lock it with the spongy foam.. whaam-baam thank you mam!! a quick fix with no money spent
