Okay I have a Venture with a 032 engine this is only the second start up. I was getting it light on the skids lower the rpms when I went to get blades moving agian the blades will not move in rotation, its stuck. It will move in the other direction. The engine runs fine when this happened I shut motor down. Need help in what direction to take. Fuel I am using is 15%Nitro and 18% oil.

if your main blades are stuck then your engine isnt aligned properly try loosening the engine mount and see if the blades will spin then if they do refer to your book for proper alignment















if your heli has a better paint job then your car you know your a heli nut :>)

Okay I will try that.

okay tryed what you said and it made no differance. So next I took the rear spindle off and checked it there was nothing out of place the bearings what free. I put it back together and it was working fine untill I put the belt of the tail back on then it started making a ratching noice. Does anyone have any other subjestion?

Saw your post on RCUNIVERSE just now.

Note that the suggestion to check the alignment of the engine won't do much.

The Venture allows the motor to move in only one direction, that being up and down, then only slightly.

You're stuck with the alignment of the clutch pinion gear, the large drive gear, and the tail rotor drive gear due to the way the three axles - clutch start shaft, main rotor shaft, and tail rotor drive pulley -- are held in the chopper. The gear mesh is determined by the fact that the six different bearings are held in the frames by molded in recesses that fit the bearings. None of the bearings (therefore none of the three shafts) can move horizontally in the frames.

If the engine is pushed up too high into the clutch bell, you will end up with the clutch shoes binding with the clutch bell. The drive train will still turn, albeit with some difficulty.

A potential problem that COULD bind the drive train in flight is if the large drive gear has enough play in its hub that would allow the large gear to tilt slightly. This would cause the system to bind enough to periodically bind while the rotors are turning. My first Venture suffered a bad case of wah wahs due to this problem (periodic binding of the drive train while flying, causing the tail of the machine to wag back and forth).

The problem you have occurs only when you have the tail rotor drive belt tensioned...that tends to tell me you've got a problem in either the tail rotor shaft bearings, possibly the shear pin that pins the rear pulley to the shaft has slid out of place, or the bearings at the drive end of the tail drive belt have a problem.

It's possible that a bearing is shot or full of loctite.

loosten the four bolts holding the boom to fuse, dont forget the little set screws. d/c rudder link and support boom. Push boom forward to get the drive belt out and lok at the boom. any damage to the boom end could cause binding. Make sure the belt is twisted in the right direction and pull boom tight. check movement if ok tightern all down. I ahd a major crash with my venture put a new boom and blades on and she runs fine

Actually, that isn't quite true. There is plenty of play in the engine alignment in order to get things out of whack. If the engine is not aligned properly, the clutch shoe to clutch liner interface will rob power and cause accelerated wear on the clutch liner.

In fact, K & S sells an engine alignment tool for the Venture; part number 1263. Not that this tool is required to get it right, but believe me, there is movement other than just up and down on the Venture.

Good luck,
John

I understand that, I have a unusual situation. I set up the venture as per instructions went to fly and the tail rotor was reversed. The bird was going l;eft as I gave right rudder. I Reversed the rudder channel and the gyro but it was spinning around like a top. Now the weird part. I reversed belt rotation by pulling of boom and twisting belt opposite to the manual and switched the rotor blades around so the BLADES ROTATE OPPOSITE AS TO THE MANUAL SAYS. I set the gain to max and put tail lock on. The thing flys great. The gyro keeps it on heading. I can hover and to forward, back and sideways flight. A little scared to actually fly a pattern with it my fixed wing tendancies will come up. I have the jr XP662 and a G410T gyro. Being a warbird pilot primarily this is a toy Did I do something wrong to the gyro but why wont she fly as recomended?

I SWITCHED THE TAIL ROTOR AROUND. tHE MAINS SPIN IN THE CORRECT DIRECTION

Interesting thread. I recently bought a used Corona that had a Hitec GY-130 gyro. The first time I tried to fly it, it would just spin around. If I set the gyro to reverse mode, it would be stable but the control direction was backwards. That is, right stick would make the nose go left. I solved the problem by reversing the control on the transmitter.

Whats interesting about this is that I just installed a new G410T gyro and had the same problem all over again. All was well after I un-reversed the transmitter. What's noticably different about the G410T (as compared to the GY-130) is that its reverse switch seems to control both the gyro correction and the control input.

Did you try the transmitter reverse switch?

yes i tried everything had all the manuals out . Now the tail rotor spins OPPOSITE of what its suppose to I compensated by switching the rotor blades. Set the gain on high left the tail lock off and it flys like a champ! One thing though I had it out nall afternoon without a screw in the tail servo arm. I got lucky! I think these gyros get screwed up from too much vibration.
I have the servo on rev like im supposed to. maybe the instructions are backward? I m a warbird pilot with lots of fixed wing time first heli though! They are interesting beasts especially in a wind!!!

Wow! That is lucky.

My G410T is working okay in both heading lock and rate mode. I'm not impressed with the heading lock performance yet because I get a very slow drift in the heading requiring a control input every minute or so. Maybe I'm expecting too much... I have the gain at 100% and no oscillations.

All I can suggest with my limited expertise is that you need the right combination of gyro reverse and transmitter reverse to make it work right. It would drive me crazy knowing I had to have the TR spinning in the "wrong" direction. Good luck!

as i said it flys fine so ill leave it alone. If some one can give me definitive instructions how to make it work ill reverse the belt.
The 410 instructions assume you are a expert, not a lot of help.
It flew the correct way before my crash where i had to replace the rotors,seesaw arms tail boom and some links. I may have damaged the gyro but the blades basically took the brunt of the crash. A bee got in my fave and a took my thimb off the rt stick to brush it off big mistake. Next time ill let the stupid thing bite me less pain!!! The rud is on rev and the tail lock is off and it sorrectly counteracts commands but only spinningf backwards. GOD hates me!!!!!!

btw i took the tail rotor mechaninsm apart to put a new sliding ring on maybe that did something!

I'm a newbie at Helli's but I have got to the the stage of Hover and a bit of Flying about!
I own a Venture 30cp as well!
some of the tip's I have pick up on the web for the Venture are!
Do you have the tail rotor rotating so the blades are running anti-clockwise (counter clock wise for our US friends!) looking from the right hand side? this I have been told is so the "up" (front) rotating blades are moving in to the main rotor down draft! (make sense to me!!!)
also I found and article some were on Runryder that states that you should have the blade grips ball link on the tail rotor mounded to the leading edge on the blades!!!! this also make sense to me as this would make that blades lead into the air-stream!!!

More on the engine mounts, theres nothing stopping you from drilling out the engine mounting holes a little as this will help in lining up the starter shaft, then as you loosely mount the engine, you turn the starter shaft with you hand till it turns really freely and smoothly. then tighten the engine up.This will help lot's in smooth running!
I'm a grain farmer so I have plenty of experience in fault finding thing's in machinery!!!! but I'm still learning on these Heli's!!!
Hope I helped in some way?
