Hi everyone,

I just purchased a gently used Align TREX 450 SE V2! I am looking for a few "SMART" suggestions on Upgrading this Heli! Let me list a few of the Upgrades that have already been made to my TREX 450:

*SPORT HEAD
*FUTABA GY401
*FUTABA S9257 TAIL SERVO
*HITEC HS-65HB SERVOS
*430XL RCM-BL450 MOTOR
*ALIGN RCE-BL35X ESC

My TREX flies Great, but I am now looking for EXCELLENCE! Before anyone starts suggesting to just go buy a PRO, I am very well aware of the Benefits of a new Purchase of the Pro! Except I want to Upgrade this as much as I can for Better Performance & eventually give this to my youngest son!

I should mention that I do have a slight Issue with having a SLOPPY Head, Swash, and Blade Grips. Everything seems to be in great shape, nothing worn as far as I can tell, and everything Tightened Up! So, with that said I am hoping a few Upgrades might take care of that problem too!

Any suggestions would be Highly Appreciated!

Thx Guys!!

New outrunner motor, scorpy -8, or even the new 450 align motor.

Get a quality belt

buy metal gears for your servos as they wreck and are destroyed.

Tuning it matters more then anything you can throw at it.

I would recommend the GP750 or 780 gyro. It can be had for cheap on the classifieds and is much better than the 401. People will argue this because they have never tried it.

Secondly, the Sport has a much better battery holder than the old SE. You'll find many Sport parts fit the SE. The main difference between the two frames is the lower half is more narrow on the Sport.

Lastly, you find the newer 450m or 450mx motors better on power and power consumption. Beware, the shaft size is 3.5 mm on these. You will need their newer pinions which are pretty nice.

Btw, depending on how you fly, maybe some harder dampers. I never used them myself.

Another option, leave it as-is and fly it. That head doesn't have thrust bearings in the main blade grips so you don't want to spin the head up too fast. I flew a combo just like that last summer and it flies great, even some backwards flying. It doesn't have the punch of the newer stuff but it flies fine. Auto's great too!

New batteries are about all I'd do for your 450SE - it doesn't even need expensive packs. My first Trex-450 flew with batteries rated for 10C discharge and flew well

+1 on what outhouse and AWittleWabbit said..

Put MG gears in the Hitec HS65's...
Sport head assy...
Align 450MX motor with correct pinion...
And a Align GY780 gyro...

All are a huge upgrade and all are cheap...
I had all the top tail gyros made..Ended up selling my Spartan DS760/Spartan Quark and kept my Aign GP780,really liked that gyro before goin FBL..
Thats another option is a FBL head and controller.Being as its going to your son,a FBL setup would be nice because the heli would be MUCH more stable....

Yup, Run whatcha brung.

+Youll know what to upgrade and when.

+Youll get every opinion under the sun, including mine; metal gears for your servos.

FWIW I put a cheap gaui fbl head and beastx(works fine with 65mgs) on my 450se and its a champ. I stupidly run the old align woodies with a 2221-8 on 3s at around 3200 and its not given up..yet.

Jschenck, I think you have the heads mixed up. The fb Sport does have thrust bearings.

I think the op gets it, but I would upgrade as you break or wear stuff out. My franken XL/SE/Sport went the same way. Much like my Pro v1/3 is now. My current Sport came into the world as a Sport.

Ya gotta love Align for backwards compatibility (whether it's intentional or not)

ah, yep - I just read "450SE" - missed the V2 and Sport head part. That head should be good for the high headspeeds the 450MX can provide.

Thanks for all the Great suggestions everyone! I know a few of you had mentioned upgrading to Metal Gears in the HITEC HS-65HB Servos, I forgot to mention that this Upgrade was already done by the previous owner, at least that's what he claimed! I will check & confirm that he did indeed change them all to Metal Gears! With that said, could the servos be part of my Problem with my SLOP issue??

Also, Upgrading the 430XL motor to the new 450M or 450MX are at the top of my list! Thanks for the suggestions!

(AWittleWabbit) mentioned that the GP750 or GP780 gyro would be a very smart upgrade!?! Like he has said, I have heard that my GY401 was a pretty darn good Gyro. If not, what exactly would I benefit from this Upgrade? I can tell you this, Hovering is a Bitch on my Heli! It takes a lot of work to have this thing Hover Clean (though I'm not the best Flyer either)!

Last, but not least....what advantage does the Sport Battery Holder have compared to my SE V2?

Thanks Again....you guys are Great!!!

Pm me for the 450m, you may have it for the price of shipping if you want.

The 401 is a Proportional heading hold gyro. The GP750 and higher are PID gyros. The 401 control loop will only try to counter tail displacement in a fixed manner. It takes ~180 degs before the gyro will commands the tail pitch slider to the max. A PID gyro will use max rudder much sooner. A PID gyro accounts for not only how much did the tail move but how hard and how fast. Search PID loop control for the nitty gritty.

If you aren't out flying the tail, I recommend not hurrying to get it. It's just that they are soo cheap, I figured why not. Id argue a novice would need a solid tail more because who needs surprises

The Sport battery mount is more solid and longer(lol) than the flimsy short metal one of the SE. Again, maybe replace after you get tired of bending it back.

You can tone down the 450 by using weights on the flybar, lower(to a point) headspeed, reducing throw, or expo in the x'mitter.

True that the Futaba 401 is an older design and has it's limits but the only real world issue I've consitently ran into with a well setup 401 is that it'll speed up and slow down on a traveling piro, specially if there is a breeze. Otherwise it works really well, especially for someone who is doing sport flying. A 401 can take you really far.

The battery tray is a good idea when you break the SE tray. Lower headspeed, flybar weights and tuning the equipment you have will really tame it down. That heli should be able to be tuned to a mild and solid hover heli without any additional equipment.
