The gy520 works the best. However i have used a 401 and a gp750 with good results in 250. But the servo is your key here, if you don't want trouble with your tail use a 9257 or bsl257 with a carbon fiber pushrod. Also 37mm tail blades.

A lot of people in our club including myself are running the GP750 and DS520 combo... It holds just fine for myself and even some of the better 3D pilots. I havent seen anyone out fly it yet, but It is a little twitchy and does take time to get set up to where you're happy with it! Ive never gotten mine as solid as a 450 tail or 600 tail but It's stable enough that it wont blow out or wag hard enough to notice unless you stare at it looking for the wag. (usually only has a small series of twitches when I punch the collective.) I am sure the DS520 would work just as well with the 780 if not better than it does with the 750. In my opinion its the best tail servo for the 250 for the money... I dont think its worth spending $100 on a tail servo for such a tiny heli that I plan on beating up!!! haha Hope this helps a little.

Logictech 2100 with a Futaba 9257 on mine, holds really well. Like Steve said many guys here flying the Align gyro and 520 tail servo with good results including Dave's funnels and hurricanes. #1 best thing you can do to a 250 or 450 is replace the wire pushrod with a CF pushrod IMO. The wire one always flexes. I've helped a few people get a more solid tail on their 250/450 with this. Make one up with a CF rod either left over from a boom support or from the hobby shop. JB Weld some threaded rod into the ends, shrink wrap over the ends to make them look nice. put the ball links on and it's ready to go. Big bonus, no pushrod guides to fiddle with.

I'll snap a few, but it won't be too impressive (yet) - it's still new in the box

I traded for a Cricket in 1986, got it off the ground a couple of times before I figured out I had too little money to wreck it. I want to build this one as a reminder of what that experience was like.

Im using the GP780 w/DS520 that was laying around from my 500s tail...Works great, but if I had to get something it would prolly be the JR3500g and MiniG or GY520.

Most solid combo I ever found on 250,450,500 was Futaba GY520 with Mks 8910 or futabas BlS257. For sure works and provides awesome results. ...Once upon a time there were Nitros, flybars and frequency pins...
