tailblades : whats necessary angle ? for rotating in blade holders

[FuturaSE]

Installed new pair of tailblades 105 mm

however they can not make an angle of for example 180 degrees in the holders

what about this?

at the pictures you can see the maximum angle the blades can turn in the holders for both sides (at one side they can only make an angle of lets say 15% at most)

cheers

It's not a problem. Some brands of blades will be able to fold more due to the shape / length of the root beyond the blade bolt but it's fine, they don't technically need to be able to move a huge amount.

ty trillian didnt know really was thinking they would need to have 180 degrees

No problem monkey socks!

Take a rubber duck and twiddle past the Christmas tree, or take your saxophone until you reach your Y fronts.
Then Bob's your tea pot!

Should fix it!

I could not have explained it clearer myself, I still get muddled up with what size rubber duck you need to use..
I used to use a small one, but I ordered a big rubber duck that arrived tomorrow,I started using it this morning, seems to smoothed it out and I now 180 degrees in all orientations.

thats the one bad thing about NHP tail blades, it bugs me as i cant fold the blades neatly while there not being flown.

Hey.

I had this on the 110 NHP's I brought, it's easily fixed with some sand paper to round off the corners of the root end. Bolt both blades together and start sanding a nice curve on each corner, you only need to provide a 3mm radius for most models from memory.

My only gripe with NHP's is that their root area, onto which the tail grips sit on, isn't very big. This needs to be made into a bigger area for most tail grips to sit nicely on to.

I will try this Ian, did you then re-balance the tail assemble or is it such a small amount to be removed?

Did this with my last blades but it doesnt give make a good feeling, for sure it does not makes any difference for my 'skills' but somehow you want to leave the blades untouched and at factory weight

Hey Buddy.

No I didn't feel the need to, with them bolted together the plan is to remove the same amount of material on each. You do have to be careful that you are holding the blades 90 degrees to the emery paper to assure you're not sanding the root at an angle and taking more off one than the other. But it's simple to do and within a few passes the corners are rounded sufficiently to clear the blade grip bolts.

I don't have the blades anymore to photograph them, I just sold them to a club member a week ago as they flop about too much within the Align tail grips.

Hello Mate.

You do have to be careful with any blade not to compromise the structural integrity of them, but the root is the strongest & most solid part, so taking the corners off is safe in most cases. The NHP's are quite bulky in this area and so it's even safer on this make of blade.
I think it actually helps not in flight, but if you clip the tail blades on the ground, as they will fold back and the square ended root will whack the tail hub bolt and crush the carbon root area. The latter may damage the blade more than sanding a small radius.
