The Aero-naut (aka TBS) Folding Pusher Prop Set

Finding the right pusher propeller set can be frustrating, specially if nobody can be certain if it will “work” in a pusher configuration.  It turns out, Team Blacksheep has exactly the propeller set I’ve been looking for which they stock for their Zephyr flying wings.  It’s the Aero-naut Folding Prop Set which seems to packaged specially for Team Blacksheep.   At $29.95 it’d be better worth it.

Here’s how  it came in:

The TBS Prop Kit

And some very sound warning for folding props.. which I’m posting here.  My main issue really with my old SW set up was that the one piece prop was bulky when putting the rig in its box for transport.


Ok on to the description of the set.. the prop centerpiece has a 6mm hole (for the shaft) and 8mm space between the prop arm for the prop attachments. The CF props that comes with the kit is 10×5 size. The two black stopper strips which goes to the front and back of the centerpiece to help prevent ‘over folding’ is made out of some plastic, which looks tough enough and which I think is unique to this set.


Here’s the measurement of the prop arm spacing using a high tech device.


And the prop set compared to a regular 10x5e prop.



I’m not so sure how much “push” this particular set can provide compared to the one piece prop. The folding prop seems to have 10-15% less surface area.  We’ll know soon enough. Anyhow, the manufacturer of the centerpiece and the props,, has bigger sized props just in case.

And We’re Back!.. with the Skywalker 1880 From

My replacement FPV platform is finally here.. after losing the 1900 Skywalker 2014  due to a bad GPS caused by the vibration of  a bad motor (bad bearings) activated by a bad operator (yours truly who ran out of TX juice), I decided to use the same platform but this time with better components (specially the motor!).   The platform remains the 1800 Skywalker 2013 CF tail boom (and wooden pan for the FPV cameras) with the elevator on top of the rudder but this time from

Here’s how it came in:


and the contents:



Here’s the Lowdown:


1) The 1880 wings seems to be thicker and looks like it also has a slightly longer root chord than the 1900 wings.

2) Unlike the 1900 wings it doesn’t come with a CF strip on top for added strength although I don’t think its needed considering its thickness and the fact that it also has a longer dihedral, covering 1/3 of the wing.

3) Because of the large dihedral, this wing doesn’t come with flaps, it only has enough room for the the ailerons.

Tail Section

1) This is the T-tail version, with the elevator attached on top of the rudder.  I think this is a good idea, in my SW 1900 the elevator is attached to the base of the rudder. This has a tendency to get skewed by the tall grass I occasionally land in.

2) The connecting plastic mechanism to snap into and remove the elevator to the rudder seems innovative although looks a little bit flimsy to me.  Looks like I need to do a little mod on this.

All the usual parts seems to be complete.  Will post the components list next.
