Trex 450 Dominator
Just started building my Trex450 Dominator, and man its really nice. I have a trex 450 V2 about 3 years ago, and they have definitely stepped up the quality, so far super pumped.

Why don't cats get gray hair with age?.....

Yep, I wish I had that in 2005 when I bought my first trex 450.

They have definitely come a long way.

Do you want to make it into the best heli you every had.

Get a ice light 50 edge + mini vbar. The 3gx is very nice gyro, but when you setup the mini vbar with governor. Its amazing on that little guy. The power to weight ratio is insane (6s version).

Flew mine 4 times today. 20 kt winds, 18f outside, 6S power and mini-vbar combined made for awesome flying. Gains are dialed in. I think my inverted backwards hurricanes were going about 70mph downwind, lol.

I love this little guy!

** few build tips **

1. don't use alot of loctite. I only put it on 1 thread only of the screw. Ask me how I know (cough, cough, dremel :crazy

2. Don't overtighten these crappy align screws, the heads strip out.(see ex. #1)

3. Don't overtighten the screws holding the tail servo bracket, they will grip then strip.

4. 1 wrap of scotch tape on the boom into the mount will help tighten up the tailboom.

5. make sure your tail slider is setup so that it is square to the tail gearbox.

6. when installing the plastic link onto the bottom of the DFC arm, I found it easier to take an exacto and dig out the inside of the plastic link where it threads in before you try threading the link on. If you don't you'll have a heck of a time getting that link threads started.

7. Don't use ball link pliers on the DFC links. Unscrew the bolt going into the link that holds it into the grip, remove the link from the grip, then twist it off carefully from the ball with your fingers, or else the link end bends.

Hope these help!

Rick

I'm amazed on the power to weight. Mine weights in exaclty at 2 pounds. Max output power:Approx. 650w/970W(5sec) , so almost a 1hp for just 2 pounds.

Ya don't get me wrong I know the 3gx is a good system, I just love the compactness and simplicity the AR7200bx offers... But it comes with a price $$Why don't cats get gray hair with age?.....

Mine is all built and running the 3GX. It's the first fbl heli I've flown other than mcpx. I figured I'd just use 3GX and get used to it. It was scary the first few flights for me but after a few adjustments I got it set up and flying better for me. I think the main adjustment was to add in some expo. I don't usually use it but this thing is so much faster than my other helis I had to. I am just waiting for some nice weather now.

My main issue with the heli is how close the tail blades are to the ground and with the tail fin on the left and the need for the heli to lean to the right in a hover they will scrape on the ground and possibly strip gears. I didn't strip any gears but did grind down the blades on the pavement. I added an extension to the tail fin for now but don't really like it this way.

Both my 600e dfc and my 700e dfc had the tail fin and blades close to the ground too. I dont know why Align puts them so close to the ground like that. It makes the heli nice and streamline like but theres no room for error on landings. If you bump the tail once on landing you are going to strip a set a gears or wipe out a set of tail blades. I fixed mine by putting a taller landing gear on the back to give the heli a bit of a rake, looks like it is jacked up a little. It also gives the tail section plenty of room away from the ground.

Well it has to do with over all geometry and cg. But Here is a tip for 450 size. You will need to learn how to land nose first and do a quick auto. Since the original 450 pro, I only strip 1 gear set do to landing. And it was because i slammed it to the ground. As long as you are in TH hold you should not strip any gears if you hit. Also don't torque you tail blades down. If they are loose then they will give when you touch the ground.

Start at a 65% flat throttle curve and work your way up to your desired head speed.

Not sure how well the Align gov's work though.

Maybe they fixed it from years gone by ?
