UPS is delivering my 450SE tomorrow and I want to get building. This is my 1st Trex, but not my 1st heli build but I'd like to know if there are any "gotchas" in the assembly before I dive in.

Thx!

Yes,
Take ALL the factory installed screws out on EVERYTHING including the head and apply Loctite to them. I had a bad experiance with a factory instaled screw in a ball link departing the from the swash plate during my test flight

Get the Align 2mm driver tool kit as well and dont try to use the tools in the kit you will jut round out the soft screw heads if you do.

i just want to second that.

it took me all of about 30-40 minutes to go through the whole bird after i got it all built out...no time at all. just be patient and take out one screw at a time. i started with the tail, and moved on down the head. just a little piece of mind. i found that most of the screws had loctite on them. but, a few didnt. and, that's why it's importatant to do this little drill.

Go to this link and download or view on-line the videos. This is really great stuff! Lot's of excellent tip and how toos!

I'm putting together an XL. Dump the locking compounds that come with the kit and buy LOCTITE! 222 is red and can be disassembled easily. 242 is blue and a little stronger and more difficult to disassemble. Seems like people are using either, perhaps preferring the blue.

Showed up this morning about 10:30. I got familiar with the parts and read the manual several times to get familiar with the assembly. Looking forward to starting assembly tomorrow after work.

Yeah, I'd planned to disassemble all the prefabbed pieces and Loctite everything as I assemble tomorrow night. My tail rotor motor fell off my Blade CP a couple nights ago while I was hovering at about 8' in the living room.. (22' cathedral ceiling) Made things "interesting" until I got it down to the floor. Thankfully no damage other than a broken TR prop.

Already have a bunch of good hex drivers and hadn't planned on using the hex keys in the kit.

I've got a bunch from runryder saved already. I'll have a look at those as well. I'm already cross eyed from watching the dozen vids I have.

My experience is opposite with Loctite. The red requires a little heat to break the bonds loose and blue comes apart with just a little extra "grunt". In any case, I've got blue and Permatex green in my toolbox so will be using that for assembly.

Thanks!

Welp, got it all together and am getting the wires dressed down.. Found quite a few ball links in the head that didn't feel like there was any thread lock on them and one of the flybar mixer arms was REALLY stiff. Someone at the factory forgot a washer. Had the right one in my junk box and solved that issue in about 5 mins. Took about 5 hours start to finish to get the mechanics built up and the servos installed. Cool little machine..

I'm hoping to have the wires dressed down in another hour or so and then start to fine tune the mechanical setup.

Honey! Look what I got you for Mother's Day!!!
