My Posts This: Topic Forum | OK, Lets try and backup a bit here.
First, on the 9L with a 16t pinion and a FULLY CHARGED 10 cell pack, you should be able to fly. Maybe not 3D, but certainly basic flying. Make absolutely sure you're getting a full charge on the batteries or you'll be chasing a ghost trying to fix the problem. If you're still having a problem with the wobble, then it's possible that your settings aren't right for pitch and throttle curves yet. Post those when you can and let the folks on here take a look.
Ideally, you should have about 5 - 6 degrees of pitch at the stick position you want to hover at with a throttle setting of 90 to 100%. If that gets you airborne too soon reduce the pitch at that point but leave the throttle alone. If you're not getting airborne soon enough, increase the pitch by a degree or so at a time, until you get the heli to hover comfortably. With a headspeed of 1500 or so, the VE should be hovering at close to the 5 to 6 degree point.
A different pinion sure won't hurt anything. You can use the Traxxas E-Max truck pinions on the VE. They are the same pitch (32) and are available in a variety of sizes. I'd get a 17 and 18 tooth and try those, but make that the rest of the set-up is correct too.
As I said in the earlier post, your throttle should be close to 100 percent the entire time you are flying. The electric motor doesn't work like a nitro motor in that it works best near it's upper rpm range. If you let the motor rpms drop it has to work extra hard to "catch up" and your flight times will suffer A LOT.
Even if you get the 8L, if your settings aren't right you'll still have similar problems. The KV difference between the two isn't so great that the 8L will solve the problem without any adjustments.
Lets start with that and see if those changes (if any) help resolve the problem
