Fixed Issues 1. Possible Issue with the One Control Chip Fixed and Extra Protection Added. The V4 had a vulnerability that showed up in about 5% of the units. Certain BECs were allowing too much voltage to flow back to the board, damaging one of the chips; thus the need for the modified servo cables to clip the voltage. The protection is now on the board, so there’s no need for the modified servo cable. It protects up to 24V accidental input through the servo inputs. 2. Elimination of Chokes. The V4 requires a choke on the Servo Y cable, and on the speaker wires longer than about 5 inches. Without the chokes, RF could feed back into the board causing some funny things to happen with the sound. The V4.1 has chokes built into the board eliminating the need for both the choke on the servo Y and on the speaker wires. The V4.1 prototype has been tested with a speaker wire in excess of 8 feet in length, with no choke. It works solid and without issues. 3. Larger Fuse. The first few V4 units had a smaller fuse on them that would do it’s job too well, and cut out as a protection under normal circumstances. The new fuse allows for the same board protection from backwards power connection, and over voltage, but does not exhibit the errors under normal use. Improvements 1. Automatic Airplane Finder. The V4.1 has a built in automatic airplane finder. If no throttle input is made for a period of about 3-4 minutes, the system assumes that the airplane has gone down, and begins to emit loud finder “beeps”. 2. Auxiliary Outputs to a Secondary Amplifier. Two new sets of pins are on the board near the speaker output. These are Left and Right, raw and unamplified sound outputs. This allows the customer to send the signal to the amplifier of their own choice. It also allows for each and every V4.1 card to become an “Ultra” system when the customer is ready. It has ready made amplifier/regulator kits that only requires to be plugged in and you go from the 2-speaker Base V4.1 to the 4-speaker Ultra V4.1. 3. Not Just Planes. Changes in the code allows the V4.1 to be used for more than just planes. Coming soon after the intro of the V4.1 card, versions will be available for cars, trucks, tanks, and boats, with respective sounds for each.
We are excited about this post! One of our readers sent this to us and we are honored to post this in remembrance of on April 18th, the 71st Anniversary of the Doolittle Tokyo Raiders. The follow is from the 70th Anniversary event and we simply could not, not, post it! To get us started, here is a video from the Doolittle Tokyo Raiders Official Website. Doolittle Tokyo Raiders Thought you might enjoy this bit of history…and a look at a bunch of B-25s you may never have the opportunity to see. The static display on +Tuesday, April 17, 2012 — this line-up of 20 North American B-25 “Mitchell” fast medium bombers, of various versions and paint schemes, gathered at the National Museum of the U.S. Air Force in observance of the Doolittle Tokyo raid on Japan, +18 April 1942: I spent about eight hours walking up and down the flight line, doing about three circuits of the aircraft, taking many photographs, learning additional new history, listening to war stories by modern aircrews and WWII veterans, seeing some old friends and making a few new ones, and absorbing lots of solar radiation — a great day! (B-25J “Doolittle Raiders, Special Delivery”) This nicely-painted B-25J carries the Doolittle Raiders’ official badge. (B-25J “Old Glory”) Patriotic nose art, polished aluminum and a sunny morning the combine for this war bird character study. (B-25H “Barbie III”) It was a very bad day for a Japanese merchant ship, if a patrolling B-25H crossed its path. According to Mr. Ralph Anderson, my high school science teacher who flew B-25s and B-29s in WWII, the proper attack technique is a shallow dive at the ship, while firing your 50-caliber machine guns. When you see bullet hits at the waterline, fire the semi-automatic 75-mm howitzer to put *BIG* holes in the target vessel … a very successful anti-shipping tactic that rarely required a second pass! Noontime on Wednesday: 40 Wright R-2600 engines starting and warming up in front of the large crowd, which has gathered at the Museum and on Colonel Glenn Highway to see the B-25 takeoffs and commemorative flyover. (B-25J “Panchito”) The first B-25 is in the air and the wheels are coming up, for the formation join-up over Beavercreek and the flyovers at the Museum: Here’s a good shot of the 16-ship fly-over commemorating the Doolittle Raid of +18 April 1942. These aircraft came over the Museum at approximately the Raid’s bombing altitude of 1200 ft AGL: Yes, they were loud, but not nearly as irritating as if they were jet engines! I obtained several good close-ups during the flyover: (B-25J “Executive Sweet / My Buck”) (B-25J “Devil Dog”) (B-25 “Miss Hap”) (B-25J “Yellow Rose”) [...]
If you want the best for the RC craft you’re piloting (and who doesn’t?), you need to explore lithium polymer LiPo batteries. Most of you already know the benefits of a LiPo battery. Yet some of the new comers to our wonderful hobby have some questions and we have seen some of you old timers mishandling your LiPo batteries. RC planes used to be advanced if they took NiMH batteries, as expensive and heavy as those were. While they packed a punch, they took away from the speed and lift you’d hope to get from your RC plane. Even fabled Warbirds and Air Hogs saw some negative effect from them. The change to LiPo, while still more expensive, does away with a lot of those downsides. But, LiPo batteries come with special care requirements. We want to set the record straight and give you the information you need to be an informed hobbyist so that you can get the most from your RC experience! Some Science: What is a LiPo Battery? LiPo batteries (or lithium polymer batteries) are based on lithium polymer ions. These batteries are constructed of a gel, under a stacked anode and cathode. But if you are you’re standing in the battery aisle holding a LiPo battery in one hand and a Lithium Ion battery in the other, that bit of trivia won’t be very helpful! Essentially, these two types of batteries are the same chemical. But, a LiPo battery has a non-flammable gel while a Lithium Ion battery uses an electrolyte gel. So, basically, the Lithium Ion batteries are more likely to overheat than a LiPo is; which is why we use LiPos in our planes! Yet, LiPos have their safety concerns as we will soon see. How to charge a LiPo battery LiPo batteries also have a fairly long life span in comparison with Lithium Ion models and their NiMH predecessor. Lithium Ion batteries begin power decay as soon as they’re made and will, at most, last two to three years. A LiPo battery pack will be rechargeable and will last at least 300 to 400 charge cycles. For some of you pilots out there, this may be one long weekend of flying! (just kidding!) So, let’s start by looking at what you need to know about charging them. First, look over the batteries before you charge them. Make sure the batteries aren’t discolored, swelling or warm in spots. Charge them slowly. Really. Cheap LiPo battery chargers often go as high as 5C (five times capacity). For LiPos, you want to start with around 1C. At most you want to use 2C with a balancer. Why a balancer? LiPo battery packs contain more than one cell. If you’re not manually setting the cell number on your charger (and you shouldn’t have to with a good quality charger), you’re risking your charger only detecting the total voltage and not the number of cells you’re charging. Doing this with LiPo batteries can result in uneven charging of [...]
The FMS 1400 mm T-28 is our favorite plane! It comes with 12 servos and is loaded with features including flaps, two-piece retractable landing gear doors, cowl flaps, running lights and two pilots in the cockpit. These FMS planes are beautiful out-of-the-box, but we love putting our own personal touch by detailing them. As you can see in these pictures. This plane has over 200 takeoffs and landings and still gives us excellent performance! It is very stable in the air and turns a lot of heads with its super scale looks and details. As far as we are concerned, FMS planes are the best value of foam planes on the market today.
The FMS Airfield B-25 Bomber on a parachute run! There have been many models of the venerable B-25 Mitchell bomber, and for good reason. Modelers like warbirds and this warbird has a generous wing size 1470MM, good tail movements and it’s a twin-engine aircraft! Watch our video in honor of Memorial Day and all of our Veterans and active duty service men and women!The B-25 bomber lends itself to being a very easily adapted design from full-scale, right on down to model size. You might be interested in our coverage of “Tondelayo” and the Mitchell B-25 Bomber in this post. We also have a video of our Maiden Flight with the FMS B-25 Bomber. What did you think of the video?

Since I was a young boy, one of the things I enjoyed the most when building a model was detailing the model and putting my own personal touch on it. Whether it was a model boat, a train layout or an airplane; I spent hours thinking about different ways that I could detail and personalize them. One of the things I love about FMS Planes is that their models are 90% complete with super details which means there's very little build time. So adding your own personal touch to these models is Read more [...] Continue Reading

These super detailed 1400MM FMS warbirds look great in the air, and show excellent flight characteristics both at high and low speeds. They fly with 4S batteries between 2600-4400mAh depending on how long you want the flight to be. The planes have a 55" wingspan so they do not have to be taken apart for transport and can fit comfortably in the backseat or trunk of most compact autos. FMS planes are the best value in the foam RC plane Market today and we absolutely love our fleet of Read more [...] Continue Reading
