Everything is installed, including the Thunder Power 2600 2s1p rx pack.
The only thing absent is fuel.

I have managed to put in half a gallon of flights thru it, running in the engine and stuff.

So far so good, everything stayed intact.

The only part that's giving me so problems is the bottom of the fiberglass canopy. I butt it up tight against the frame. Vibrations made lots of noise and eventually the G10 frame took a few small nimbles into the canopy. some trimming with the dremel is next on plan before this weekend

I would secure those antennas with heat shrink tubing to the receiver bases. I reparied 2 of my AR7000 today, replaced all antennas (8pcs), think 3 of them was damaged in the solder joint.. Lucky me it did not cause a crash... Great looking bird by the way!

Sorry, was late to reply,
Thanks for the tip, i'll definitely take note of those areas

I've put about 2+ gallons thru it now.

2 crashes - both pilot errors
1st was an over flared auto, tail blades clipping along the ground, heli at 60 degs, broke the tail rotor grips, tail blades.
Main blade took a small chunk at the roots when the blades fold back upon toppling.
Damage: main blades, tail blades, tail rotor grips, tail shaft, tail boom, autorotation gear
2nd was inverted approach that got a little too low, grass won.
Damage: Main blades, flybar, spindle, main shaft, pitch arm, tail boom, landing strut plates

*On both crashes, the entire torque tube transmission remains intact.
In fact, in the first crash, the autorotation gear was stripped but the torque tube bevel gears held up! There have been a lot of talk and concern over the gears strength, i have to admit, i was pretty worried myself. but now i'm all

1 incident,
last weekend, was doing engine tuning and plenty of climbouts and forced descents, the tail boom rotated in the mount until the tail rotor disc is facing the ground at 45 deg angle. maybe i didn't tighten the boom mount tight enough, I've seen the same thing happen before with the MA stratus. there was a slight scrap at the tail blades ends and i changed those out.

Today's flying went great without the rotation issue

Just finished building mine today. Got it up into a quick hover to check tracking. I still need to do some work on the head geometry as its bloody twitchy! and I am waiting on some new links as I may have over reamed a couple on the swash. Otherwise, this weekend should see a decent maiden flight. Excitied!

It seems pretty critical from experience with all helis with mixing lever on pitch arms.

The long linkage to swash must be exactly 90 degrees to the mixing lever, as indicated in the manual(the cad drawing is way off 90 degrees though!)
One way to determine that is to check for equal positive and negative pitch.

If there is more positive than negative, the angle is more than 90 degrees, lengthen the long link, shorten the short link.

If there is less positive than negative, the angle is less than 90 degrees, shorten the link link, lengthen the short link.

For my x90, the top mixing lever looks almost horizontal.

Do jump in if i overlooked anything

Hey thanks for the tip ammo! I'll be going over my head tonight to double check. The link lengths in the manual arent exactly right so it would be great to see what you ended up with?

Most hobby shops that also have planes will have a small metal "L" shapes ruler, it is used to align rudder and elevators, I used it to set the 90 on the links.

Ammo,

you still need to make sure that the links on one side of the head are equal to that of the opposite side, typically you will get one side set, then pull the links and with a caliper measure and make sure the other side is the same. To make sure the rod C and the mixing arm is at true 90 you need to take the guess work out of it, the 90 degree ruler will allow you to lay it up against rod C and the mixing arm to verify the angle is at 90
