No, I swear lol. I haven't been to Mass since college 92' to 96'. The big bottles will last a long time. Take piece of chalk or crayon and mark the heads on the screws as you thread lock them and torque them.R.I.P. Roman

I went to college in Mass too. Why would I mark the heads other than marking my territory?

I now understand why you should mark the bolts. I am assembling the rotor head/main shaft assembly and it's easy to bypass one...

I have a ? I was hoping someone could answer. The piece between the swash plate and the rotor head... Is that assembly supposed to be tight on the main shaft. I'm sorry but I do not know what it is called. It connects with two of the ball linkages on the swash plate. This is a flybarless head. If anyone knows if I need to tighten it firmly to the main shaft?

This part:

Absolutely has to be tightened. It is the swashplate driver, and if it's loose (and not properly aligned) you will have serious issues getting the heli in the air.

Read the assembly instructions. When properly installed and aligned, the pushrods from the grips to the swashplate will be vertical, and parallel to the centerline of the main rotor shaft.

That's the one. I have been trying to get it aligned according to the diagram in the manual but the manual isn't too precise. Can I be off by a few millimeters up or down or does the placement have to be precise?

Those pictures were exactly what I needed. I was confused on the placement of the driver but your description of the required alignment along with the pictures cleared things up for me. The only thing I am worried about is how much to tighten the bolt that holds the swashplate driver to the main shaft. The last thing I want to do is snap a bolt . Dave thank you for the help. I can stop pacing around and get back to the build.

Make sure the thrust bearings in the blade grips are assembled correctly and lubed...open side of the bearing cage faces in. The races are marked "in" and "out". When you installed the main shaft in the bearing blocks, make sure to leave the bolts loose and square everything up on flat glass surface; there should be no drag on the shaft and everything should spin smoothly. Also, pay attention to the main shaft, there is a top and bottom, and the ships will go under the rib between it and the upper bearing block. You're shooting for zero up and down play in the shaft.R.I.P. Roman

Make sure you disassemble every screw and ball that was installed by the factory as well. I've seen swash balls that were only started a few threads out of the box. When you build Align stuff, you have to do it with the mindset that all factory assembly was done by a 12 year old who just finished a shift assembling vacuum cleaners. They have no idea what they are assembling nor the importance of it being assembled correctly.R.I.P. Roman

Looks good in spite of SpongeBob.

Yes -- for all "preassembled" parts in the kit. Take them apart, make sure they're assembled correctly, lubed and loctited as needed.

How tight? You don't want it to move on the shaft. Don't overdo it, but if you're mechanically inclined, you'll know when it's good.

I was conservative tightening the bolt. I am mechanically inclined though it's not my profession. This is my first time building a helicopter and I want a nice machine. I spend countless hours on the sim the least I can do is put in the time in to build it right hopefully. I finished the rotor head and the fuselage or main frame(if that's what its called). I've been flying rc planes for years.

I like how your mind works adamsZ06. That could not be put any better in any other words to explain what to expect in pre-assembled parts.
