Hi
I am rebuilding my FBL N9 and I was wondering what size tail blades to use?
I used 105mm but I read that 95mm are better since they put less strain on the tail. What do you suggest?

it depends on how much responce you want, 95's will move it around just fine but the 105's will make it feel more crispy.

Has anyone used the SE hub and the stock SAB 105mm tail blades together?

Yes, that is my current set up.

The 105's are not recommended if you do a lot of hard stops to reverse piro's. It is very hard on the tail gears and crown gear.

I do not fly hard piro reversals and have had no issues running the 105's.

95's are the recommendation for hard stop to piro reversal.

I see they have the Hyperdrive TT's in also...

About the metal tail gears, are there any drawbacks to having these in a crash? I stripped my plastic tail gears on a bumpy auto landing when the tail just barely swiped the ground. If I had the metal gears, would I have just damaged something else (like the Hyperdrive oneways)?

Thanks

One thing to remember is that 105 tail blades will put less stress on the tail servo.. seems backwards, but since the larger blades need to deflect less for the same amount of 'thrust' the servo does not to work as hard. because of the non-linear geometry a 95 deflecting at a higher pitch takes more oz-in on the servo than a larger blade deflecting less.. even if the thrust is the same.

Does using a little delay on the gyro help prevent stripping the gears?

I like the 105s better than the 95s.

Since the Synergy has been out it's been recommended to use delay in the gyro.

It was a retorical question, and a suggestion, since a few said they stripped gears.

yes it will damage the crown gear... at least mine did . the hyper oneway was ok.

I usually run radix 105s, but recently switched to the KBD 102 tail blades. IMHO the plastic blades have just enough flex so you dont strip gears. Another big reason gears get stripped is insane piro rates coupled with trying to get the tail to abruptly stop. Bad combo IMHO.

I have found no need to do the metal tail gears, I would prefer to strip the tail if need be to save all the gears in front of them.

My crown didnt strip in flight only on impact haha. i have heard of people stripping plastic tail gears in flight thats the reason for metal tails.

i dont have any delay in the gyro with radix 105s , it will piro at insane speeds and stop on a penny and give you change back..
