FT Mighty Mini SE5 Biplane WR (609mm)
After 6 years of Flite Test foamies, an epic WW1 battle is at the edge of your fingerprints! The FT SE5 Biplane was designed to build fast, fly slow and look great both on the ground and in the air. We put a lot of effort into taking a design that is known for being a handful and making easy to both build and fly. The FT SE5 Biplane is a 3 channel slow fly aircraft that can turn on a dime and be flown in a very small location. Loops, barrel rolls, wing overs and many other classic maneuvers are all possible with this little warbird. The FT SE5 Biplane is also a perfect companion for its arch rival the FT DR1, an iconic German Triplane that flew the skies and shared lead with its British nemesis. Our hope is that the SE5 will be the source of many happy memories as you take to the skies and recreate epic battles with your friends in your own backyard.
We want you to have an amazing experience both in building and flying, This kit comes with everything you need to complete the FT DR1. Push-rods, control horns, firewalls and all other items needed to make this airframe electronics ready are included in the kit. If you choose to purchase our power pack F and wheels, balance, flight performance and assembly will be quick and easy.

Please watch recent build videos before removing any paper from the foam! Some videos may use white foam board, which is no longer available and has now been replaced with water-resistant foam board.
I found the design of this plane brilliant. Thanks, Josh!. It is cool how you can get a curves saddle shape out of flat foam board, with a wing chord and dihedral. It looks great in the air, and the shape closely replicates the real historical plane.
I flew it for the first time last night, and it flew great. It was quite stable. I found it initially much easier to fly than other 3 channel planes including the Mini F22, and the Arrow. I think this is both because it is slower, and because it is more stable with digedral.
I made mine per the instructions. I found it fun to build, but not the easiest. I used a 7x3 prop instead of the recommended 7x4.5 because that is what I had. It worked fine on that. This is the first 3 channel plane I have made that takes off with wheels. That confused me at first, because I am used to steering planes on the ground with the left stick.After the first flights, I added a mix so that both sticks control the rudder. Now, I can steer in on the ground with the left stick, and in the air with the right stick the way my instincts work.
As someone else said, the SE-5 is not a beginner's plane. I crashed 4 times trying to hand launch (broke the right and left lower wing at the fuselage, easily repaired with 30 min epoxy) before I figured out that take offs require nearly full throttle and both hands on the sticks from the outset (wheel launch from pavement). I had set her up for the recommended low throws, but the rudder is way too powerful even on low throws. I now have the rudder low rates at 37% on my Tactic TTX 850 which gives about 3/4 inch throw to each side and I use 30% expo (first model I've ever felt the need for expo). She's still quite touchy on the rudder though the elevator is fine. I built three lower wings and two upper wings before I got wings that didn't have too much wash-in on one side of the wing compared to the other. Never did get them perfect. Be very careful in building the single surface foam board wings. I made roundels from Monokote trim and a compass. It would be great if FT sold decals for the warbird models.
Now that the SE-5 is sorted (as the Brits would say) she is quite fun to fly when the wind is less than 5 mph. She's the first model I've built that snap rolls. I keep a little power on during landing approach and she lands quite well.
In a review of the Emax 6x4.5 prop, someone said the prop was easily broken. Mine have taken a lot of abuse without breaking or showing a stress line. It probably matters that I learned that if you program your ESC for "brake on" you won't break a prop doing a belly landing or in a tip over (unless the motor is still running when you land or hit something.)
I haven't been able to find any documentation on how many amps, max and continuous, for which the Emaxx 2204 (2,300 KV) motor is rated. Here are my Watts-Up meter readings for the Emaxx 2204 on the fully charged battery Flite Test recommends and sells (the 850 mah, 3 cell, 20C): 1/2 throttle is 4.5 amps, 3/4 throttle is 11.0 amps, and full throttle is 15.3 amps. I tried an APC 6x4E prop and the readings were nearly identical with full throttle pulling 16.0 amps. That's an awful lotta amps for such a small motor and explains the short flight times. Everything I've read suggests using an ESC that is rated for at least 20% more amps than the motor pulls, which means the Emaxx 2204 with this prop and a three cell battery should have a 20 amp ESC. Also, an 850 mah, 20 C battery is capable of delivering 17 amps (.850 x 20 = 17). So, full throttle pushes an 850 mah, 20C battery awfully hard. The 12 amp ESC I'm using is rated for 16A burst, and I only use 3/4 to full throttle for take off and the occasional loop so, I'll let it slide, but for those of you who fly full throttle for extended periods please, be aware of how close to the edge you are pushing an 850mah, 20C battery, and how over the edge you may be pushing a 12 amp ESC.
This was my first FT kit (Christmas gift from my son). From plans I've built the Tiny Trainer (Suppo 1510) with well over 100 flights (2/3 3-channel, 1/3 4-channel). She's my go to plane at lunch time. I've built an Old Speedster, a Mini speedster (neither of which will hold a heading, but are always drifting off into a turn right or left), a Simple Soarer (over 60 flights), a Mini Scout that I spray painted and had to lengthen the nose to get her to balance without ballast (she will hold a heading and is easy to fly), I've also built a foam board 53 inch wingspan high wing trainer (4- channel) that I designed. I have 60-70 flights on it.
I can't thank Josh and the crew enough for the very pleasant addiction you have given me for foam board RC planes. Thanks so much.
This is a very easy build and along with the videos it is fool proof. Only problem is when will the skins be available? I have not been able to find a place that can do a full size print of the download ones and getting them to make a tiled version costs by the minute for the length of time to figure out the correct scale!
