I've been out of the hobby for several years and I'm trying to get back into it. I used to have a 3DX-400 with a spektrum DX6. Now I have a Trex 450 with a Spektrum DX6. I was wondering what the best servos and motor was for the money. I know for a gyro, the gy-401 was the going thing several years ago, how about now? What about the servos and motor. Any input would be greatly appreciated. Thanks!

Servos - I've run both the Hitech HS-65's and Align 410's on the swash. Happy with them both. If I'm buying today definitly get metal geared servos. I don't have a 'pro', I hear they break servos gears even metal gears so do some research there. For my old SE metal geared servos would have saved me money.

Motor, again I'm happy with my old Align 430L 3550 now that I'm running it on 4S. Buying new today it'd be the new 430M motor that comes with the 450 Pro.

Gyro - really hard to beat a Futaba 520, favorite gyro that I own. Many people running the Align 750 here and like them. Most seem to prefer the 750 over the 780 but I've seen both run well. I haven't owned either one. If you already have a 401 it's a great gyro and no need to replace it until you are doing piro maneuvres. Be sure and get a good tail servo. Align 520, Futaba 9257, BLS257, JR 3500. There are other choices that are good also. I run the 9257 and the 9650 and they work good for me.

+1 for jschenck comments. He knows his stuff.

My 2 cents.
my 450 pro --GY/520, align 410 metal gear, 9257 rudder, stock motor/esc/spektrum 6200rx.

Servos. Ran the stock Align plastic gear 410's when I started. Plastic gears strip if you look at 'em funny. Crashing of course didnt' help. Switched to metal gear 410's and they've lived through a couple harsh crashes with no issues. Go metal gear. As for MFG, i've only used the Aligns so far.

Tail servo, All 9257 except for 1 BLS251 on a heli that isn't complet just yet (trex-700). See a couple local guys with the 251 and it is solid.

Gyro. Own 3 GY-520's, one Align 750 and one Align 780. All easy to setup. All hold the tail well on various helis. I like the GY best. Have a 4th on order now for a new project.

i fly a 450 pro clone, with hitech65hbs pretty dang tough servo and cheap tp rebuild, i havent found that the pro strips them faster then v-2. on my pro they seem to survive a few crashes before stripping same with the v-2.

i loe the scorpion 8 motor. on 3 cell power with high c batteries its got power to spare. i recently just upgraded to ice 50esc and went to 4cell batteries. with a 12tooth pinion goverd and 3300rpm the heli is just awesome it has tons of unbogable power.
with the esc on gov mode the heli is super stable. this alone was a huge improvement over the 35amp align esc. .

i have the futaba gy520 gyro and align ds520 servo and its rock solid.

the only thing i think i ight upgrade down the rd is switchn to hitech5065 digital sevos. for now im more then happy the heli as it is.

also i think if i had it to do over again i might by the align kit and upgrade to ice50esc. i dont think i can fly a normal esc again after ueing the castle ice 50 ,
