I have finally upgraded from a cp pro to a new Trex V2, I have been using Hitec 65mg servos and the futaba 9257 on tail, but have just been using my old G90 gyro. I was waiting for the new Spartan ds650 to come out but I am getting tired of waiting for it. Do you guy's that have a GY401 think it is still the perfered gyro for the trex or is the new technology that much better for a noob that is just doing forward flight and a flip every once in a while. I have stayed away from the 401 do to the piro consistancy problem but I guess I still don't understand how importance that is. Any help would be great on finishing my trex thanks.

Oh one more thing, I was told that the 401 does not hold the tail as good as the spartan or some others in fast backwards flight during hard 3d stunts, but if you do the new tail mod do you guys think the gyro will hold comparable to the spartan or comparable gyro's Thanks.

fwiw..

401 is still my default gyro...The Hitec/Logitec2100 combo should be great, and I run the 2100 on my beater...Holds better than the 401, but is much trickier to set up...401/9650 is set and forget, will hold any maneuver the heli is capable of...If you want a better tail, try a set of the tail blades from the TT mini Titan...Work notoceably better than anything else I've tried..T/R weight mod makes a huge difference also...

401 is probably still the most common trex 450 gyro.

Personally I prefer the CSM 720, mainly because of the piro consistency, which I want, and use. But as you are not after that, then the 401 would be ideal for you.

I still have an old GY240 on my Trex and it does everything I need it to do, flips rolls whatever. The 401 will handle anything you will be doing for quite a while I'm sure.

I have 3 401's and 1 2100T that I'm flying right now. I like the simplicity of the 401 myself and they hold great for my flying skills...

Tom..... No "D" flying....

Thanks guys for the repleys, I'm not hearing anything bad about how they hold or the piro consistancy, so maybe I'll look into buying one I see they are around $110 or so. I don't know how new the 401 is but I just would hate buying one and watching a new futaba gyro come out, has anyone heard any news on this. thanks

There are people whose flying skills are good enough to notice the difference between the piro consistency of the 401 and better gyros. (I am not one of them.) By the time your skills reach that point you will have owned several gyros, and will recognize the difference and you may then decide to go with something better.

I just finished the build on my Trex 450 se New V2 today, and I initially ordered a JR G500T, but after reading of so many complaints about the difficulty in setting it up plus another post that suggested that the 500T doesn't run well with the 9650... I immediately bought a 401 and secured an RMA # for the 500T before it even arrived.

So here I am... my build is finished and I am waiting on my 401. I have a 240 on an Century HBv4 and it's rock solid even after many (and I mean many) crashes. I have never had a problem with my 240 and I'm sure it will be the same with my 401.

When so many others are flying the 401, I think is it says alot about it's realiability as well as it's ease of use.

LGT 2100T would have better piro consistancy from my experience. I had tha 401 w/9650 and had excentric piro in fff. Tried the 401 w/9257
had the same wop wop wop during FFF piro but now with the 2100t/9257 and balance mod the piros are perfict in all flight. FFF is constant rotation instead of the wop wop wop seen before. fwiw

the 401 was designed for a 30-50 size heli, and will work fine on a 90, but hard 3D on a 90, it struggles

so that being said, a 401 with a 9650/9257 is more than capable of handling ANYTHING a trex450 can throw at it

the constant piro rate comes down to the tailend not having enough weight to give total authority

even in a perfectly weighted tail to match a good piro consistency, a stick banger can blow the tail out just as bad as an un-weighted tail, therefore they go buy a bigger more expensive gyro trying to fix a collective management issue

the 401 will hold beautifully in 100metre tailslides, rolling tailslides, hurricanes and inv-rev flight with a gain between 30-50% in HH mode

just my opinion, and it will vary from person-to-person

!boo!
