lsjpeng -> New Falcon props and spinners (7/14/2012 7:40 AM)

Falcon has some new CF stuffs coming soon. I like to share some test data in here. Not sure when will they available.

New props: 21x13.5 and 21.5x13
Both are V2 (light version). Current draws are similar to the 21x14 V2, see datalog attached.
Test condition: Himax 6330-210, CC ICE 80HV, Power Unlimited 10S LiPo pack.
For those pilots who feel 21x14 or 20.5x14.5 are too hot, you may try these new props.

CF spinners: original and slot
It seems to me they are similar to the Marquet spinner but lighter. See pix below. Both are pre-cut to fit the Falcon CF prop. The prototype I got is 82mm diameter. Jarvis of MPI told me that they will have 76mm diameter as well.

CF landing gear and wheel pants: vertical height is 8.5" (from mount surface to wheel axle). It adds 1" more clearance (I was using Bolly F3A CF landing gear; ~7.5" vertical height) that I feel more safe when using the pricy V2 prop [:D] It is slightly lighter than the Bolly, but not significant. My old 7.5" height Bolly CF landing gear plus Hyperion wheel panels are 152 grams. The new 8.5" height CF landing gears plus wheel panels are 145 grams. (both w/o wheels)

In my opinion, all the new composite e-airplanes on market are very light. Weight seems no more a big issue. We don't have to spend big bucks to save few grams like old days. But it is always good to have more options available for us. [:)]

We have both sizes of the new props in stock now and have samples of the new spinners (82m and 76mm). A few sets of the landing gear/ wheel pants arrived as well.



g_mkoch -> RE: New Falcon props and spinners (7/14/2012 4:31 PM)

How much for the spinners with the cooling holes?



Dre -> RE: New Falcon props and spinners (7/14/2012 4:48 PM)

I would like to see these made with the integrated drive washer option like Marquet has for the Hacker motors.

F3A Unlimited -> RE: New Falcon props and spinners (7/14/2012 9:07 PM)

The spinners are not yet available but will have a retail price of $79 and that includes the cooling slots and the prop cutouts (cutouts fit falcon electric props)



nonstoprc -> RE: New Falcon props and spinners (12/12/2012 4:36 AM)

Chris or anybody can kindly provide the height and weight information for the 82mm production Falcon Carbon spinner? Thanks.



lsjpeng -> RE: New Falcon props and spinners (12/12/2012 6:34 AM)

82mm CF spinner:
Weight: 23 grams
Height: 70.2 mm

76mm CF spinner:
Weight: 19 grams
Height: 63.7 mm




nonstoprc -> RE: New Falcon props and spinners (12/12/2012 1:56 PM)

Thanks Luke. Appreciate it.

 I see you got a good answer. Thanks Luke
 These spinners are pure art. The quality and look are something you have to see to appreciate. Mike



gaRCfield -> RE: New Falcon props and spinners (12/13/2012 1:37 AM)

I just bought one. Can't really beat the combination of weight and cost. I'm not excited about the 6 screw method but maybe I will get used to it. I am thinking it might actually be a way to rid some extra prop adapting hardware and shed more weight?

The Truturn back plate, even the turbo prop, still look 'over built' to me, but I really do like the single bolt mounting.



nonstoprc -> RE: New Falcon props and spinners (12/15/2012 4:10 AM)

Joe,

Thanks.

To secure the spinner via a single bolt, I guess it may be possible to make a small cut at the top of the cone and beef up the inner?



nonstoprc -> RE: New Falcon props and spinners (12/30/2012 12:29 AM)

I have the 82mm Falcon spinner. It looks very nice and is super light.

One question though. Does Falcon make a 10mm back-plate insert? The 8mm insert does not work with Neu F3A motor.

It looks like the default 8mm insert can be pushed out. Once the insert is out, the backplate is ready to accept the 10mm prop shaft (thanks Chris for the tip). I did use a 10mm drill bit to clear a tiny bit of material on the backplate. The fit is excellent.

I am attaching several pictures to show the product and excellent fit with the Neu collet.








can773 -> RE: New Falcon props and spinners (1/1/2013 3:37 PM)

Gents,

Just want to share something on the Falcon spinners. I just got mine and went to mount it up. When tightening the prop nut the backplate started to deform. Since this didn't seem normal I started to take a look at the backplate closer.

The spokes are actually raised above where the prop hub lands on the backplate. This landing point for the prop hub is perfectly sized for a Falcon or an APC prop, but I had a Mejzlik on it, which has a much larger hub. You can see in the picture the hub of the Mejzlik lands on the spokes because of this and could quickly destroy the backplate if you didn't realize it and torqued the prop nut right up.

You will need to fashion about a 1-1.5mm spacer to get the prop away from the spokes when using a Mejzlik prop, then its perfect!




Dave Harmon -> RE: New Falcon props and spinners (1/1/2013 10:00 PM)

If Falcon will mfg a 70mm spinner like this....I'll buy 2 of em'.
Hopefully...this will happen soon.



F3A Unlimited -> RE: New Falcon props and spinners (1/1/2013 11:09 PM)

They will be producing a 70mm spinner but not sure of the time frame for delivery yet. Only received confirmation that they plan to produce them.



rgreen24 -> RE: New Falcon props and spinners (1/2/2013 12:57 AM)

Hopefully an 80 mm as well[:D]



nonstoprc -> RE: New Falcon props and spinners (1/2/2013 1:43 AM)

I dropped some high strength Loctite separately on the threads of the screws and the mount holes and wait for it to dry. Hopefully this can build up good amount of "friction" to hold the six tiny screws in place.

Love to hear any good methods to secure the screws in place, even after a swap of prop at the field.



underdw -> RE: New Falcon props and spinners (1/3/2013 5:07 PM)

I've used the 6-screw style spinner on IMAC planes for many years. A bit of blue locktite is all I use.
Careful about using too much or too high strength locktite, as the hex heads are prone to buggering. I often replace the button heads with socket head caps to get a bigger hex size.
When I have to remove/re-install a spinner at the field, I don't re-apply locktite and haven't had a problem.

gaRCfield -> RE: New Falcon props and spinners (5/3/2013 3:41 AM)

What is the trick to get the center spacer out?



nonstoprc -> RE: New Falcon props and spinners (5/3/2013 3:49 AM)

You could use a small puller (sold in most auto-stores) to pull the spacer out.
