New gyrocopter model

Some of you know that we have discontinued the PT25. Today we are announcing the replacement model. It's called the MKII (Humpback) least for now. You never know, the name could change before the first shipment goes out. Anyway, it is based on the PT25 but with some improvements and changes.

The major highlights are:
1) Approx 30% reduction in the horizontal tail surface. We have found that a hugh horizontal stab just isn't needed.
2) The vertical fin and rudder have been reshaped and now has a larger rudder.
3) The top of the fuselage aft of the pylon has a more stylish 'curve' to it now, hench the nick name "Humpback".
4) The pylon has been reshaped for a more stylish look as well. Also the gimbal pivot point has been lowered by approx 1" to reduce the 'pendulum' effect at full power to reduce the pitching up problem.
5) the rudder servo has been moved to the rear of the fuselage to free up room in the radio compartment for 2.4 ghz RX's that have 2 receivers.
6) the pitch and roll servos are now mounted directly to the pylon core eliminating the need to come up with some hap hazard way of mounting the servos.
7) The head is new too. It's smaller then the Gen II head but larger than the Doozy head. Of course it's called the Gen III head and we tried a few variations untill before I was happy with it. It is compatible and interchangeable with the Gen II head kit.
8) The gimbal is just slightly different and is NOT backwards compatible with previous versions and it's also called Gen III gimbal kit.

We will have some at Muncie with intro pricing. We will be offering the show price to anyone who can't go to Muncie and will be in effect until we get back home from the fly-in. The only difference will be shipping costs (no shipping cost at Muncie). Shipping will begin sometime between May 17 -21. Anyone interested in the intro pricing can contact us directly at:

(no price talk on the least from us)

See you in Muncie,

PT-2 New Model

Anyone interested in sharing the import costs to the UK? Maybe we can put together a bulk order and reduce the overall cost?

The first batch of 24 Humpback kits has nearly sold out. Still have a few but the intro price will be going away soon, maybe by this coming weekend... Don't go by what you see on the website. Put a kit in the cart for the special price.
