Inccessant Rotation

I have recently purchased a JR venture 30 and have set it up and got it running. However, I am having a problem getting the helicopter to keep from spinning counter-clockwise. I have tried setting the trim all the way over, and held the rudder all the way over and still it spins (although somewhat slower). I tried moving the rudder the other direction and this causes the spin speed to increase so it everything seems to be installed in the correct direction. I tried adjusting the servo to start have the neutral stick position offset to compensate for the rotation but now I have the rear rotor fully deflected and it is still spinning, again somewhat slower but still spinning all the same.
I tried removing the gyro from the system on the off chance that it was over compensating but this didn't change anything and I still had the same results, counter-clockwise spinning.
I replaced the main blades and snugged them up so they don't flop and still no luck.
I did notice that the main blades seem to be offset when they are spinning and that they appear to be rotated slightly from each other. Could this be causing a problem? If so how do I fix it?

Any ideas about what I can do would be greatly appreciated!

your tail drive is probably slipping check that.

PS: sounds like what happened when my belt drive slipped on my heli

How can you tell when it is tight enough?

Just a thought but have you checked that the belt is not twisted inside the tail boom? If it is twisted it would be applying the wrong rotation on your tail and this could lead to your problems. Of course this is assuming that it is a belt drive tail. The heli manual should tell you how to set the tail belt so that it does not slip. I have a shaft drive so I wouldn't be able to help you with this.
Sounds like your main blades are out of track, This shouldn't have any bearing on what is going on with your tail not holding.
Check that the tail belt is not twisted this would slow the belt down and cause you lots of trouble. the belts in the boom should not be touching at all.

check that it is properly set exactly as the manual says. There has got to be somthing obviouse that is just begging you to find it. These heli's just dont normally have problems such as this without it having somthing to do with good old H,E (Human Error)

Back to your Blade tracking
You need to balance your blades first, If this has been done, Then when you spool up your heli which ever blade is higher you can unclip the linkage and turn it to change its length so that they come into track. Only turn the linkage one full turn at a time if the blades get further appart then go the other way. just keep making the adjustment till the blades are perfectly in line. Be sure to only adjust the one blade and get that to track to the other. or you could be throwing your pitch out of whack.

ok on my heli the inphasestrapassy was stripped (gear connected to belt) check if you can move the tail without the main rotor moving. i this is it you'll need to dig into your heli and pull that out and get it replaced. how does this sound like the problem? with my heli the pitch nessary to make it stay orentated made the gear slip/strip. I found this out because when the tail was 0degrees it spooled all the way up. then at the regular amount of degrees you could hear it slow down and see it slow down. check this in 3D mode with no pitch on the main blades.

I'm experiencing a similiar situation with inccessant rotation during takeoff. The rudder blades are not parallel to the helicopter, though endless trimming attempts were tried. The belt is also slipping causing the blades to drag. Further attempts at reajusting the gears proved useless. Any suggestions?

unscrew the back four screws on the main frame, (just 4 turns out, not all the way out) and pull the tail boom back. now take it and spin the main blades. if you can make them spin 2-3 times just by turning by hand you're fine, if more keep pulling, if less push in a bit. Causes are usually from holding the heli up by the tail so the boom might push in. if it still slips (the belt not any gears) then you may have stripped your belt. also make sure the tail rotor is level, otherwise it may cause problems.

Thanks, I'll try this next time if it doesn't fly. I returned it to the shop for further inspection and confirmation that it's not flawed.
