They're performing close to expensive servos (people like me can't see much difference) aside of being fragile in crashes (gear striping).

As for tail servo - I had Esky 0704A + HXT500 and it worked far better than some other combinations... So, I'll probably start with similar combination on HK250GT too...

I was getting serious tail wag today and narrowed it down to the belt tension.
When I pulled the boom back to tighten it I noticed it was stretching.
I pulled the belt out from the boom and it's seriously stretched.
Has anyone had any belt issues?

Have you tried the esky 704b? with other servo combo?

I've heard of few people having it. that's why i asked on another thread about kevlar belts. may be an option for you. but what's your flying style?

According to the Trex 250 manual the bearings for the main blade grips are "Bearing 682XZZ (4)2.5x8x2.6mm". The bearing for the seasaw is "Bearing 681X (4)1.5x4x1.2".
Do you know or have you tried these for a replacement to the wrong bearings in the main blade grips and to replace the bushings in the seasaw?
If they do work I would like to order a set or two before my order shows.
Thanks.

Eric
I did mine, the Align bearings are a straight swap.

Sport style. I like to just zip around. No 3D yet.
I ordered an Align belt for now.

I've just ordered it and it will arrive along with HK250GT (hopefully) - so I'll be able to try it then...

I have HXT500, HS81, GWT HPX Park Servo to try with. Maybe HS56 and HS50 but not sure why would I go with them... Will let you know...

Did you use the original screw for the seesaw bearing? The T250 uses a special shouldered screw there.

I used the bearings and screw from the PL kit, the stock screw is too wide for the ID of the bearings

The PL had bearings in the see saw where the bushing is in the GT?
