Logo600se stripping main gear
My setup
Logo 600se
693 edge fbl
ice hv 80 (med timing, 8khz pwm, gov 10)
scorpion 5020-450
12t pinion
gensace 25c 12S 4000 (testing showing these performing similar to 40C thunder powers though)
1800 idle 1
1900 idle 2

I've been running this same setup with 12S 4000 20c turnigy's for some time and had no problems. Once i moved up to the gensace, i'm stripping a gear per flight. I'm setting the mesh pretty tight on the high side of the gear, but most of the gears seem out of round such that if its tight on the high side, there's lash on the low side.

I'm doing mostly big air and smooth 3D with the 600se, but if i do any tic-tocs hard, i inevitably strip the main gear. Any suggestions, changing a main gear per flight is getting expensive

no, but i'm assuming the 6mm shaft isn't flexing that much. I'm wondering if the mesh wasn't set tight enough, but its hard to set it tight when there's runout on the gear. Some i get are round, others are not.***Logo 600 vbar***Henseleit TDR vbar***

You are right about the give in the 6mm shaft. I have not stripped a gear yet, but I don't fly hard 3D and still have problem doing tic-tocs.Team Synergy, Rail blades, Team Scorpion, V-Team

Try lowering the gain for the motor on your esc.

Doesnt sound right, first make absolutely sure u dont have any vertical play in the shaft, then when you mesh the gear also check for vertical play between the 2 gears, on the tight side you should have almost no vertical play if u flex the gear at pinion side.
To be sure u dont have binding loosen the pinion on motor shaft and spin maingear, most of the times by shifting the motor in the mount u can get a very smooth but fairly tight mesh.
Problem with 600 Se is that the gear is marginal for 690s so u have to be careful with the collective as the gear flex under load which instantly strips it. Saying that i've had no stripping since doin the above checks. Also make sure you run silicone or other lube on the gears

It's the ice esc, even though the governing is looser than a kontronik or v-gov, it puts more load on the maingear because it's so deep into the load by the time it reacts.
The 700e guys were seeing the same thing.
It seems counterintuitive, but turn your gov gain up if you can.
I could kick the crap out of mine with the 5020-450 and jive 80hv without issue.

For his kind of flying I really doubt it is the castle gov that is stripping the main gear. Is it mod 1 or 0.7?

mmc205 describe the process you use to align the pinion to the main gear.

i aligned the herringbone perfectly and pushed the motor against the gear and tightened the motor mount screws. There is no binding, but nor any lash now. I'll report back once i fly it.***Logo 600 vbar***Henseleit TDR vbar***

Try some lithiun grease on the gears and check your pinion temp after a flight. If its scorching hot you mesh is likely to tight.

Mainly 600SE's stripping gears?
Through reading the various threads, it seems that stripping main gears is occurring on the 600SE. Is anyone who has stripped main gears running the Mikado carbon frame set? It would provide a stiffer frame, less flexing along with a third bearing block.

I'm thinking of building the SE, but a little concerned about stripping main gears. I'm planning on getting the carbon frame set if I build the SE.

Also are the auto bearings holding up on the SE's, with all the added stress of the large rotor span.

Thanks,
Brian

I'm running the kaos frames which have a much sturdier main axle configuration than stock and have stripped gears, unfortunately i dont see the carbon frames helping as the problem is, the gear itself flexes under load, just grab your main gear and flex it at pinion side.
The best i can advise is to set it so you have almost no vertical play between pinion and maingear when u flex it, BUT make sure the pinion is aligned, you have no vertical play in the mainshaft and not binding.
The other culprit is running hot motors w/o lubrication. I have a friend who does not know the meaning of collection management, needless to say he stripped the gear on his second flight, setting up as above it's holding up
