This is the Checkpoint Endurance Flight of my Flyzone Micro SE5a, modified with an Eflite UMX Radian AS3X Receiver, Hobbyzone Sport Cub S Brushed Motor, Motor Mount, Gear / Prop Shaft, and UMX Beast 3D Rear Tail Wheel.

Flyzone Micro SE5a w/ UMX Radian AS3X Receiver & HBZ Sport Cub S Motor Flight (9 min 36 sec)

Having recently been given this stock Flyzone Micro SE5a from a generous Hobbytown USA Associate from his personal fleet, I went to work right away, modifying it with my personal touches for outdoor use. The UMX Radian AS3X Receiver allows for communication to my Spektrum DX6 while adding AS3X stabilization to combat outside forces like wind and gust. The Hobbyzone Sport Cub S Motor, along with Motor Mount, and Gear / Prop Shaft work seamlessly with the UMX Radian AS3X Receiver while adding additional power over the Stock Motor. Finally, removing the Rear Tail Skid and adding a UMX Beast 3D Rear Tail Wheel allows for smoother take-offs and landings with less drag. The final detail was to add some weather-beaten rain weathering over the fuselage for an aged look.

To debut my latest modified plane in the fleet, I chose to perform a different type of outdoor flight.. A Checkpoint / Waypoint Endurance Flight across several areas of the large park. The goal was to take off from the parking lot and land on both baseball diamonds situated on opposite ends of the park, followed by landing back at the original parking lot. The basic rules for this...Continue Reading

I just got back in from my lunch hour at the park after testing out the Parkzone Ultra Micro Stryker Powerplant Combo on my UMX Radian 2SBL with Dual Servo Ailerons:

1) Eflite BL180 3000Kv Brushless Outrunner EFLUM180BLB
2) Eflite Stryker Propeller 3.75 x 3 EFLUP037503

Last night, I made a last minute decision to go with the Eflite BL180 3000 Kv Motor, after researching in the Stryker forum that pilots were consistently getting anywhere from 7-8 minutes of flight with the Stryker setup, and I really wanted to max out the capabilities of this little powerhouse Radian.

Sunny day, about 65 degrees Fahrenheit, wind was blowing fairly steady about 9-11 mph. I brought (3) Eflite 2S 7.4 mAh 30C lipos for the testing.

On my first flight, I did about 50% aerobatics (Loops, Rolls, Immelmans, Split-S, Hammerheads, Inverted) and 50% Thermal Hunting. This Radian was more than capable of handling the aerobatic forces as I tossed the Radian around in the sky with this more aggressive powerplant. There were no signs of wing stress or flexing, even at the wing tips. Very impressed at this point as the first part of the test was successfully completed.

I was also able to capture one Thermal, as I remembered that there was a baseball diamond with sand and dirt adjacent to the grass park I was at. Thinking that I would probably get some warmer rising air from that location, I throttled up with a full throttle punch against the wind towards that direction, and wow.. this Stryker setup...Continue Reading

This is the Maiden Flight of my Eflite UMX Radian 2S Brushless with Dual Servo Ailerons (This video is best viewed in Full-screen and in HD). Bonus Flight Footage at the end of the Maiden Flight.

Eflite UMX Radian 2S Brushless w/ Dual Servo Ailerons Maiden Flight (10 min 57 sec)

This project is my response from losing my first UMX Radian about the same time last year due to a sudden incoming wind storm that blew my first UMX Radian with it's stock brushed motor system backwards out of the flying field, across the highway, past several neighborhoods, and finally out of view and range. After searching for hours, I finally considered the plane lost. I told myself, never again will I lose a plane due to the lack of power to come back.

The project started with taking photos of the stock system for reference. Maintaining the identical amount of right thrust and down thrust was critical for it's flight performance. After studying the stock layout, I carefully removed the stock receiver and brushed motor and motor mount with an Xacto knife. Using a Dremel, I carefully hollowed out the interior to make room for the new UMX Yak 54 motor mount, new Eflite BL180 2300Kv brushless motor and new Spektrum EFLU4864 6-channel AS3X receiver BL-ESC.

The UMX Yak 54 motor mount was used due to its ideal size (after cutting down some of the mounting base perimeter). I chose to use the Eflite BL180 2300Kv motor due to the robustness of its design, silent operation (compared to...Continue Reading

This is a flight demo of my UMX Whipit Glider, modified for EDF-powered flight (This video is best viewed in Full-screen and in HD).

Eflite UMX Whipit EDF-Powered Glider Flight - Broken Silence (8 min 25 sec)

This project started out as a conceptual joke between friends as we discussed how cool it would be to see this Ultra Micro DLG have an EDF powering it. So I took out my UMX Whipit that I got tired of really quickly when I first got it months ago, took out some spare parts (UMX Habu EDF Housing, 11750Kv Motor with a new DF Fan Blade, and AR6410BL Receiver) and converted it into an EDF-Powered Glider.

Rudder Roll at 1:10
Loop at 1:21
Large Rudder Roll at 2:06
Close Whistling Pass at 2:14
Loop at 2:33
Split-S (haha) at 2:42
Wind Current Alert at 4:00
High Altitude Glide at 5:36

I managed to find some insulative packing foam left over from a shipment of PC's at work, noticed a piece of the foam that would work as a mount, cut that piece of it and carefully using a Dremel, shaped it further to sit flush on the 36mm CG of the Whipit. I then cut a slit on the top of the foam mount where one of the EDF Housing mounts slots itself in. After dry fitting the pieces together, I glued them all in place with Slow Cure Epoxy. The EDF Unit was mounted with a neutral thrust line.

The AR6410BL Receiver is mounted to the rear of the wing and held by double-sided tape. The stock Whipit Receiver in the nose section still operates the control...Continue Reading

This is my second 3S recorded Flight of my UMX P-47 Thunderbolt using the Hyperion 3S 240 mAh Babbelbatt and the Eflite 3000Kv Motor / Eflite 5 x 2.75 Propeller combo.

Eflite UMX P-47 Thunderbolt 3S Flight - 3S Babbelbatt (Part II) (5 min 19 sec)

Following the successful first flight of my UMX P-47 on 3S using the Hyperion 3S 180mAh Babbelbatt along with the Eflite 3000Kv Motor and GWS 5043 Prop, I decided to dial down the Prop to the Eflite 5 x 2.75 Prop as this combination has always brought out the best level of performance in my other UMX planes. Dialing down the Prop from the GWS 5043 also remedied the Over-Current Protection Shutoff (OCP) and was non-existent on testings. I had also tested out the Eflite 3000Kv Motor / GWS 5030 Prop combo on 3S prior to this video but was not impressed with the performance of the UMX P-47 with this setup.

The UMX P-47 on 3S, using the Hyperion 3S 240mAh Babbelbatt and the Eflite 3000Kv Motor / Eflite 5 x 2.75 Prop is a powerhouse rocket. Maneuverability is excellent with the increased speed and power. Loops are tall, and aerobatics are sharp and responsive. The best part of this setup is that it provides the best of both worlds.. the 3S Babbelbatt does not alter the slower flight characteristics of the plane, but also allows the plane to "boom and zoom" upon command. The Hyperion 3S 240mAh Babbelbatt will not fit in the stock battery cavity, so the Battery Hatch Mod is highly recommended. My Target Flight Time...Continue Reading

This is my first 3S Flight of my UMX P-47 Thunderbolt using the Hyperion 3S 180 mAh Babbelbatt.

Eflite UMX P-47 Thunderbolt 3S Flight - 3S Babbelbatt (Part I) (4 min 22 sec)

My fellow RC Pilot "Captain Muscles" lent me one of his Hyperion 3S 180mAh Babbelbatts to test on my UMX P-47 to get a taste of 3S power on a UMX plane. With my UMX P-47 already outfitted with an Eflite 3000Kv Brushless Outrunner and a GWS 5043 Prop, I already knew that this plane would be a speed demon.

Prior to flight, I had throttled the battery at about 30-35% for about 15 seconds to eliminate the chance of OCP (Over Current Protection) from kicking in with the ESC and causing the plane's motor to shut down mid-flight and potentially causing a crash.

Upon take-off, flight controls and throttle appeared to remain similar to my original setup with the Eflite 3000Kv Motor / GWS 5043 Prop on 2S. However at 75-100% throttle, the plane changed its personality dramatically and the speed increase was very noticeable.. and impressive! Along with the speed, control surfaces also became more responsive with sharp maneuverability. I apologize in advance for the farther out shots of the video footage, but this plane now eats a lot of sky very quickly. A completely different animal altogether on 3S!

If there is any drawback to this power, it is the reduced flight time, as I was only able to achieve 3 minutes of effective and safe flight time to prevent damage to the 3S Babbelbatt.. an...Continue Reading
