Im hearing reports of BLS-451 not designed for heli use...

Anyone having lots of flights on them without issues in a heli?? Pls comment or share your experiences..

I have three bls 451's for my Xtreme 50 but reading that some people are having problems.. Wondering if I should just sell them and get 8717's..

Any thoughts or comments would be appreciated here on this forum or PM..

Thanks!!!

I don't have any, but I know a few people that do. And I've been hearing more bad reports, than good. Glitching, locking up, not responding.... I think I'll wait for awhile, and let Futaba get the bugs worked out.

Hell... I can fix that.
Uh oh..
Nope.
It's ***ked!!!

I have 3 on my CCPM Freya. They perform well and I have had no problems so far, but I am keeping my eye out for any problems or signs that they may be defective. Remember 9451s and 9351s are not designed for heli use either but many (including myself) are using them with great success in helis. Before this whole glitch problem a servo was just a servo regardless of whether it was spec'd for ground or air.

I was a victim of the initial batch of defectively programed Hitec digitals when they were first released and had one fail (locked hard to one side) in flight causing significant damage to a 1/4 scale plank. Hitec seemed to acknowledge and correct the problem where as the initial response form Futaba seems to be to simply deny that these servos were spec'd for helis and the problems that result are because of improper use. This concerns me greatly.

Honestly I would bench test them thoroughly and put some time on them on the ground looking for any potential problems and if you seen none go ahead and use them. Seems as they're working for me so far and I am very happy with the responsiveness and light performance.

This just dumbfounds me, I got 3 on my Trex 600N with about 40 flights and I like them alot. When I set them up I had next to no CCPM interaction, they are very smooth and powerful, and center very well. I have flown them hard, with alot of pitch pumping and they have been awesome. I replaced 9252's with these and they are definitely better, for me.

Up until tonight, after reading the negative comments, I would have thought them to be the perfect cyclic servo. But, no doubt some are having problems, so I'm going to keep an eye on them but I'm still going to fly the heck out of em.

I'm using a 2.4 Spectrum module in my 9303.

I've got 4 of them on my Trex 600N and I have been having glitching troubles from day one, I have swapped out the G3 5014 Receiver with a 5114, re routed the antenna wire away from the Duralite Battery, checked every wire and made sure every nut and bolt was tight on the Heli and still no end to the glitching. Today I switched the G3 5114 receiver into "Mode B" and I got in 5 glitch free flights. I'm not sure I'm comfortable with masking this problem, I think they need to go to someone with a DX7

I've put together three of these 600N's and used 9451's in them with absolutely no problems, this last one I decided to go with the BLS 451's and it appears that wasn't a good decision

Go to this thread straight from Futaba rep. Not suitable for heli or airplane use.

I have 4 of them on my 600N, and I have 6 gallons on the heli with no issue, but I am also using a DX7. They are very smooth and fast. Does voltage have anything to do with glitching? I started using thme with 6V, but now I run them at 5V just because 6V was too much for me at my current skills.
