I accidentally drilled the mounting bolt hole on my only V913 top shaft for an
Align shaft, instead of the Blade 450 shaft.
Looks like my first 450 FP will be a Trex 450 clone.
The V913 top shaft was drilled to accept a 1/4 inch piece of aluminum
thick wall tubing, and then I drilled the tubing inner diameter to 5mm.
It's a perfect fit, and I used the original head mounting bolt from the 450 CP head.
No glue here.
The top shaft spins perfectly true with zero slop. This should work beautifully.
Hopefully I get a day off so I can actually finish it.

I finally got phoenix mostly working and can manage some pretty good turns some of the time, its a fine balancing act between the bank angle, elevator and rudder that changes constantly. I can turn it on a knife edge with just elev and ail but that is probably cheating.
But I can fairly easily do inverted flight and will work up to rainbows, tic tocs, funnels etc. Its great this sport has so many things to learn.

carried out test hover and the first thing I need to change is the hk gyro its all over the place .swapped it out for a kds dual rate so much better .bumbled around in low rate for two bats ,the cyclic with the cx4 swash and 913 head set was fantastic ,can now fit it into the 109 shell and open her up in the feild

I am putting mine together now, and am hitting one problem after another.
First, the head was too low and I would have gotten canopy strikes so I had to drill a
new mounting hole.
Then I found the V913 ball links are a completely different size than any of
the normal sizes and I will have to cut a V913 link and attempt to drill and thread
the shaft so I can put a 450 link on the other end to match the 450 swash.
Then I found that since I raised the head, all of my linkage that I was going to
use was too short.
I was about to put it on the shelf for a while.... LOL just kidding.
Thanks for letting us know about your good results.
Sweets, are you using the stock V913 lower link guides, or did you use a swash locker setup?

V913 Head Bolts
If you (like myself) forgot to order a screw kit for your V913 head,
here are some bolts that will work.
I found these at the local hardware store.
For the blade bolts you need (2) 3-48 x 1/2" bolts along with (4) matching
washers and (2) 3-48 nuts.
For the 2 smaller bolts in each grip clamp, you need (4) 1-72 x 1/2 bolts,
(8) matching washers, and (4) 1-72 nuts.
Here is what it looks like when you are done.
This thing feels like one solid block of aluminum. It's extremely rigid.
This baby is going to be AWESOME.
Also shown is my latest upgrade for my 300x FP, a carbon fiber stabilizer set.
This will shave 3 grams from the tail assembly, and give me better forward flight.

been hit by a sam-------that's what it looked like .had the blue sport blades on (not carbon skinned qs 8008 blades) and was just setting the rates up (fine adjustments) when also being a member of the poo eye sight club, clipped a small branch on a fly pass (near to workshop ,not in field) and bang---flybar one way,blades and blade holder another way and copter skidding along the floor. in my hast to fly had not boiled the new main tower. the plastic on the 913 head is more brittle than the f45 head ,it sheared at the head grip point,which is why fly bar and part of tower one way,blades and blade grips another way and half a tower still on copter -------all re built and test flown again ,but this time away from any branches. steve...have kept the tower as standard as I don't have a swash locker . just ordered another two cnc flybar sets from etreme for the f45,they should fit the 913 tower ok

450 FP Custom Swash Locker
Today I drilled and tapped my washout base and installed a pair
of 4-40 set screws in order to build a dual arm swash locker.
I drilled through the thick part of the base, and there are lots of threads
for the set screws to grab.
For a 4-40 tap, the drill chart says you need a 2.26mm ( 0.089") drill bit.
I used a 2.23mm bit and it seemed to work with no problems.
Pictured is one of the set screws to show just how many threads are
holding these babies in place.
An added bonus is that this swash locker is balanced, unlike the Honey
Bee CT lockers I have been using.
I found a new trick for centering holes before drilling into soft metals
such as brass and aluminum.
In the past I tried drilling free hand, and with a drill press.
Both ways always seem to end up with slightly off center holes.
This time I took a very sharp hobby knife and marked the spot exactly
where I wanted my hole to be.
Then I spun the knife, using it to start the hole. This created a guide for the
( A center punch would serve the same purpose, but all of mine are at work. )
This worked out wonderfully. It may not appear that way from the photos, but that is
because of the way that the washout base is machined.
The set screws are perfectly centered on the main shaft, 180 degrees from each other.
A CNC machine could not have done a better job.

Since I don't know if I will be using the lower linkage guides, and the
V912 head uses a weird size link, I had to chop the end from the lower
links and drill them so I could attach a 450 ball end.
This way, the linkage will fit snug in the link guides, should I decide to use them.
Since I raised the head to give more balance bar clearance, my links will have
to be longer than stock.
They turned out better than I expected, but took me almost an hour to make.
How did you guys solve the V913 linkage issues? Same solution?

Some pictures of the 300x FP with the new CF stabilizers.
They save 3 grams and will let me mount the battery a little closer to
the main shaft, improving performance.
The really cool part is that I had to buy a set of stabilizers anyway from the
last crash, and these were only $4 more than the stock parts.
I'm really diggin' the new look. She is a sexy beast.
