Intro:

During the 2016 Weak Signals Show (aka Toledo) both Horizon Hobby and Hobbico announced micro B-25 Mitchell aircraft. After a thorough analysis of both models I fell in love with the Flyzone B-25 Mitchel by Hobbico. The choice for me was easy; the Heavenly Body scale color scheme, uses batteries I already have for the Flyzone micro P-38 (now discontinued), same power system as the Flyzone micro P-38, no stabilization technology on board, clear windows everywhere on the plane instead of painted, and the price point being a good $10 USD lower than the Horizon Hobby version. With my decision made, it was a matter of time before I bit the bullet and purchased the TX-R version. Fortunately my loving family told me to order it for Father’s Day 2016.

 

Unboxing:

I knew the plane looked good, but seeing it in person blew me away as soon as the box was opened. Everything was well packaged with foam inserts that cradled the pieces. Refer to the unboxing video above for details. The included batteries for the included charger were packed down deep, I had to pry them out gently with a screwdriver. Be sure to pull all the foam inserts/covers as possible as every square inch of the foam inserts contains a piece of the plane. For additional protection, the included battery is sealed in its own plastic marketing case as it would be seen in the local hobby shop. Be sure to get the back of two small screws out and don’t lose them, they are for mounting the wing to the fuselage. I also noticed the guns on the fuse sides are not stick out waiting to be broken off, it’s like they are molded in and laid flat. The nose and rear guns are very thick and designed to take a beating to prevent easy/quick breakage.

 

Assembly:

Assembly of the Flyzone B-25 Mitchell is simple and straight forward. The two wires and connectors in the wing are pulled through the front of the wing and connect to the appropriate connectors in the fuselage. Do take your time and be careful here. The wires and small and fell a little fragile, not to mention the space is tight and I found my fingers would sometimes get in the way, especially with the servo wire connector. For this reason, I don’t recommend taking the wing off the plane very often, unless you have some properly sized tools. Once the wire connectors are connected, slide the wing in place and use the two small screws to mount the wing to the fuselage. If you want the optional landing gear installed, just slide the gear into their respective slots.

 

TX Setup:

First, ensure the landing gear is in the plane and you are holding it firmly around the tail to prevent prop strikes and runway if the throttle channel is reversed. If you are using a Tactic transmitter, follow the instructions in the manual and manual addendum(s) found on the Flyzone website. If using an AnyLink module, refer to the TX-R addendum for the B-25 on Flyzone’s website and the manual for your AnyLink manual. I found with my Futaba 6J and AnyLink v1 module I needed to reverse all 4 channels in the radio. Be sure to check and reverse control channels as needed. Also, at this time, mark the CG location and/or where the battery is to be placed to achieve proper CG. Note: if the battery is pushed forward too far, the plastic head on the battery will interfere with the nose wheel/rudder servo and cause binding/sticking of the servo. Sadly I could not find any documentation in the manual or addendums for proper CG. Fortunately Motion R/C had a recommended CG of one inch from the wing leading edge on their website. I found this CG location to be spot on and is about where the wires run down the wing. During the control setup, double check the rudder decals. I found mine were not cut through all the way and not lined up with the hinge line. This created a lot of binding and loss movement of the rudders. I carefully peeled the rear portion of the decals off and cut them to be wider around the top hinge and more aligned with the hinge line. I then carefully put the decal parts back in place, moving them a little bit away from the hinge line.

 

Taxi Test:

Since I will be flying the B-25 off grass with landing gear removed, I tested the steerable nose wheel on Berber carpet. WOW! The B-25 will turn on a dime and has no problem taxiing on the low pile carpet. If you will be flying indoors or from pavement with no debris, rolling takeoffs will be easy. However, there is not much ground clearance with the props, so any type of debris is likely to cause an issue.

Flight:

For the maiden flight I picked a day where winds were 0-3 mph, mostly cloudy, about 85*F with a heat index near 90*F. With standard preflight check complete I simply pointed the plane up, ran motors up to about 75% and gave her a gentle toss. The Mitchell flew out of my hands with no issue, very predictable and uneventful hand launch. I found I needed two clicks of up trim for “hands free” flat and level flight. Once comfortable I gained altitude and stalled the plane purposely from level orientation. The B-25 just drops the nose and enters its glide path for a very uneventful stall. Loops are doable, but not recommended for flying scale. I found aileron rolls to the right to be non-existent, but to the left it’ll roll 360* but lose a lot of altitude. I’m okay with this as I like to fly my warbirds scale, and aerobatics on a bomber is not scale to me. I found the dual rudders to be very effective in the air. Just to try it out, I was able to keep the wings level and turn the plane using only rudder. The flex in the vertical stabilizers did not appear to impact flight. The B-25 will yank and bank just fine, but a more graceful appearance in the sky will require coordinated turns (using rudder and aileron together). The scale Heavenly Body color scheme looks fantastic in the air, the yellow accents really helps with visibility. The green camouflage color can help it wash out against a green background, but that’s the goal of the camo colors. Since it’s a micro it’s not designed to be flown very far out. Flight is easily achieved with a throttle setting of 60-75%. She’s an agile but gentle flier. I set my TX timer for 5 minutes, per the manual recommendations for outside flight, and after 4 minutes I could tell the battery was fading off as more throttle was required to keep her flying. I found 4-5 minutes will put the pack at storage charge (about 3.7-3.8V). Landing sequence is simple, fly her in pattern, then about six feet off the ground cut throttle and glide her in.

 

Conclusion:

I really like the Flyzone micro B-25 Mitchell. The color scheme is great, the level of details in the foam is fantastic, working rudders are effective, steerable nose wheel is a bonus, and the clear plastic windows is superb. Unfortunately, the plane isn’t meant for being taken apart often with the two piece construction and do pay attention to the rudder decals and battery placement to prevent binding of the rudders. I really enjoy this little bomber. If you’ve wanted an R/C B-25 and can’t afford the larger ones (FMS for example) this one feels the need perfectly without breaking the bank. I recommend this for any intermediate to advanced pilot wanting a nice scale-ish warbird bomber that flies gently but is agile enough to turn on a wingtip. This is a fantastic micro plane by Flyzone I will be flying quite often.  Watch the unboxing video and video review below.  Thanks for reading!
