    Horizon Hobby is on a roll with the ultra micro series of airframes. The Stryker is already a legendary airframe and now it is available in the ultra micro form factor with a brushless power system no less.

    The recent release of the F-27Q version of the Stryker was a major re-design of the airframe by Q. Q. Somenzini himself and included many improvements in both durability and performance. It seems all of those improvements have also been ported over to the ultra micro form factor including the new twin rudders, the nose mounted landing gear, the magnetic hatch and the outrunner type motor.

    Having recently prepared an article on the full size F-27Q, when the chance to review to the ultra micro Stryker came up, I wasted no time signing myself up to the task. Lets open the box and see what more is in store for us...

    What do these ratings mean?

    The ultra micro F-27Q Stryker is shipped in a usual colorful box that doubles as a storage and the carrying case which ultra micro airframes are famous for.


    As you open the box, you will see the ultra micro Stryker that is ready to fly along with the battery and charger. 

    The manual is located under the Styrofoam box.

    Overview

    Take Stryker thrills with you wherever you go with the Ultra Micro Series F-27Q Stryker 180. It packs the punch of an E-flite® 3000Kv 180 brushless outrunner motor that delivers exhilarating speed and climb performance, just like the big F-27Q. It also has functional twin rudders so you can push the limits with extreme aerobatic maneuvers like flat spins, snap rolls, blenders and more. Perhaps best of all, you get this awesome performance without having to sacrifice any of the smooth, predictable flight characteristics that have made every Stryker a sport pilot favorite.

    The ultra micro Stryker seems to be a spot on smaller replica of the full size F-27Q Stryker. I really like the new blue color scheme and the contrast that the red and black on the bottom of the fuselage provide. The same improvements that have been added to the full size Stryker are visible in the ultra micro version. The battery is accessed via a magnetic hatch which also has a generous cooling hole for the electronics. The nose is protected by a removable rubber nose cone which is designed to pop off in the event of a crash to protect the rest of the airframe from damage.





    The super small 180 size 3000kV motor is visible in the rear along with the  3.75 x 3 prop. The dual rudders, which make the full size Stryker a blast to fly, along with the and the landing gear have been carried over from its full size counterpart.





    The AS2000L long-throw servos that actuate the control surfaces are protected on the bottom of the airframe with plastic domes that are color matched to the fuselage. The servos are attached and ready to go out of the box and all that remains is to charge and install the battery before binding it to your DSM2/DSMX receiver.

    Manual


    Ultra micro airframe manuals are very detailed and aimed towards beginners with an abundance of information ranging how to charge the battery to how to set the control surfaces. The ultra micro Stryker manual is no different and will help you get on your way to your first successful flight with the UM Stryker in no time. The CG point is documented as 67mm (2.7") forward of the firewall which places it right about the middle of the hand launch opening in the bottom for quick reference.

    Let me start this by saying, just like its bigger brother, the ultra micro Stryker delivers in the performance department. The UM Stryker is very easy to launch. You can launch by using the provided launch spots in the bottom of the airframe in an overhead manner or simply grab it from the wing and toss it like a Frisbee. I used low rates for hand launches as it gets up and goes fairly quickly and I did not want to mistakenly over correct the elevator and cause an mistakenly crash right out of the pipe. 

    Once the UM Stryker was up in the air, a few clicks of trim were required to get her to achieve level flight which I applied using the transmitter then later corrected using the U-bends on the connectors. My first flight happened on a fairly calm day and I really enjoyed the performance that the UM Stryker provided. It can go from a gentle sport plane which can cruise around at crawl speeds to a fairly quick speed demon in  the flash of an eye. Roll rates with high rates on the ailerons are blistering.

    Similar to the full sized Stryker, inverted flight required a bit of down elevator to maintain level flight. The UM Stryker can perform inverted harriers just like its bigger counterpart and upright harriers transitioning to elevator landings are a blast to perform. There is a good amount of wing rock in high alpha flight but amazingly the ultra micro Stryker can fly through it without stalling to one side. On successive flights as the wind picked up around 10 mph, we flew the UM Stryker without any troubles and even enjoyed riding the wind and keeping the UM Stryker in stationary flight. I think the UM Stryker may be the best ultra micro airframe for windy conditions.

    Knife edge flight and spins are possible with the dual rudders and the boomerang maneuver, which I still cannot get perfectly flat, is very fun to perform. When I first started flying the full sized F-27Q Stryker and started to learn the boomerang, I was still using a lot of throttle to get the airframe spinning. I later discovered that throttle is not really required after the spin starts and in most cases you can get even flatter on the spin without the throttle. 

    Full throttle flight is very exciting and I think that the UM Stryker is the fastest airframe in my ultra micro fleet as expected. Due to its tiny size, it can get out of view fairly quickly so it is probably best to keep a good eye on it until you get used to its flight envelope.

    The rubber nose cone does a good job of protecting the airframe against mild crashes. In most cases, the contact with the ground causes the rubber cone to pop off absorbing some of the impact. During a failed recovery from a boomerang maneuver, I went in nose first and with some speed. The impact caused the Stryker to break right above the leading edge of the wing a crush the nose a little. I was however easily able to glue the UM Stryker back together and straighten out the foam easily and was back in the air by the time the battery charged again.

    The provide 2S200mAh battery allows for a comfortable ~8 minutes of flight time. Which can vary drastically depending on how much you get on the throttle. Landing the UM Stryker is always fun. I find myself trying to choose between a regular belly landing, an elevator landing to the ground or an elevator landing where I try to hand catch it on the way down. Regardless of your choice, you will most likely be wishing you had a few more batteries on hand as I found myself not getting enough of the UM Stryker.

    Ultra Micro Stryker (Pilots, Stills & Video: Burc Simsek and David Smith)





















    The UM Stryker is a very welcome addition of ultra micro airframes. Being a huge fan of the full size Stryker, I had great expectations from the the ultra micro Stryker and I am glad to report that it did not disappoint. With a great airfoil and delta wing configuration, the flight envelope is excellent allowing you to cruise around at comfortable speeds running low and slow circuits or to simply open it up and watch it get up and go. The dual rudders allow for some crazy acrobatics ranging from snaps, spins, to full fledged knife edge flight.  If you still are on the fence about the UM Stryker (or the full size one for that matter) stop reading this and go get one for your self and try it out. Just make sure you get some extra batteries as well. You wont be disappointed...
