8~9 inch variable pitch propeller for foam airplanes.
For the ultimate in indoor 4D flight performance, look no further than the 4D VPP System from Hobbyking, offering backwards flight, vertical rolling, mid air stops and so on. This unit features two sizes of blade in the box 8 and 9 inch, carbon fibre mounts and hard plastic fittings.
This is a lightweight unit giving flexibility for set up in almost any type of indoor foam airframe. You can have the servo for "VP" mounted up front or using a push rod, have it tucked away out of sight.

A really nice, tidy and versatile unit with no motor modification needed.

not the best, but works , make sure to take the time to tighten all the bolts and make sure to take time to set up the curves

Nice system!

You can mount the servo directly on the supported CF mount or on the fuselage and control pitch with a pushrod.

I had to make one correction though: the recess in the prop hub that leads the propeller root was too narrow near the full positive pitch position, causing the hub to bind. I had to sand it a little so the hub could move freely over the full range.

Note that the hole for the propeller shaft in the hub is only 3mm, so you carefully need to widen it with a reamer or drill if you want to use a motor with a 3.14mm shaft. It would be great if HK could support a 3.14mm hub.

I recommend to use the innermost hole on the servo arm to control pitch. The range is then just sufficient for that and you want to use maximum servo force anyway. When I connected it to the 2nd hole of a TGY1440A, I couldn't get full negative pitch at high RPM. If the horn is too long, it may also flex under load, causing the control bearing to tilt and slow the propeller down.
