A year in the making! Introducing the new FMS F3A Explorer, the latest creation in the FMS Aerobatic line of models. With its elegant and graceful lines, superb flying qualities, the F3A is a must for the aerobatic pilot to add to his hangar. Working with RC Hobbyist’s worldwide, FMS has developed this aircraft to meet all the precision flying requirements needed to compete in F3A aerobatic competition.

This review is being written after my purchase of my second FMS Explorer. After 2 years I retired the first as Id plain wore it out. It suffered several pilot induce crashes and suvived after gluing the broken carcas together, flying well after repair. It's a foamy and two years off regular week end use it started to get loose wing mounts etc so I decided to retire it. I had to replace both the wing servos at 18 months as one of them failed out right. Fortunately it was on one aileron not the elevator. I love fkying it it fit great in my van assembled so you get into rhe air fast. Now the bad...for such a well engineered aircraft the hardware packege falls short. My second Explorer had screws that were too short and too small to properly mount several of the control horns. I didn't bother to contact MotionRC as I had some replacements on hand. This issue would have stopped many of you cold from completeting the build. The manufacturer needs to up its quality control as everything else is so well engineered then it falls short on less than a $1.00 worth of hardware, loosing one star just for that. It cheapens the experience.not in a good way. The good...FMS has improved the supplied prop. My second Explorer flys noticable better with the new prop, with better midrange power performance.
I was very happy with the 1st 3 flights.it tracks very well. All ma11ers are crisp. However I think it could use more power for up lines and other ma11ers like 2 circles in a row. I am sure with more flights and experimenting it will get better.
This is an awesome airplane. It is super quick to assemble and get airborne. In the air it is powerful enough for unlimited vertical and tracks on rails. Put it in high rates and it will do some 3D. Highly recommended
During assembly I swapped the motor for a Scorpion 3020-12 based on reviews that this was a little tail heavy out of the box. I also swapped the factory ESC for a CC Phoenix 45 I had laying around. Basic assembly was straight forward even with the electronics swap and using an old FM receiver (Berg 7), the only problem was the horizontal stab spar, it was almost twice as long as it was supposed to be, but 4 seconds with the dremel fixed that up. I used a 1/6 mix for the aileron servos instead of the included Y harness in case I want to use flaperons later, though I see no reason for it after flying it. As for the rest, I am running an APC-E 11x7 with no spinner and an Admiral 3s 2600. On the maiden it flew weirdly, very. On takeoff it had right turning tendencies as opposed to left as every other airplane in the world does, that almost ended badly (trees on that side of the strip). It flew as if it was fighting itself, it was out of coordination no matter how I trimmed it. It required constant rudder inputs to get it to track straight. It was also really twitchy. I ran the expos (from -30 to -45 on the Futaba) out for the right stick and took the upper wing off and now it is a completely different airplane. It tracks dead straight on takeoff and flies like you would expect. It also requires less up elevator trim, though the elevator is still slightly above the stab for level flight. I didn't attempt too much 3D as I was having too much fun tearing around with it, but it will easily hang on the prop. With this power/prop combo it has unlimited vertical and moves along really well. Flew for 5 minutes and it took 1700 mah out of the battery with a lot of WOT. The landings are fairly quick, but very manageable. I use a field with 1 1/2 inch grass and it stops as soon as it touches down, but thus far, no damage after 4 flights. Takeoffs were made from a dirt running path with no problems, it rolls 12-15 feet, but could be shorter if I got more aggressive. All in all, I like it, but not with the upper wing on it. CG is about perfect with the extra weight up front. Oh, and the directions are terrible.
Flew this plane again using a 4s 2200 pack and it was a completely different plane. I am still only giving it 3 stars and calling it weird because of the flight characteristics. With the 4s the performance is much better and oddly enough it seems to handle better as well. Take offs and landings are very easy and uneventful.
Not sure what else to say but this is a very odd bird. I set all of my controls at neutral and for the first flight it was so far out of trim I almost lost it. I finally was able to get the plane trimmed and it flew 12ent but seemed under powered for a pattern plane. Upon landing I observed my control surfaces and noticed that in order to get it straight and level I had about 1/8" up elevator about 1/4" right rudder and the Ailerons were slightly off neutral to the right. Second flight was much better since everything was in trim but still lacks power and just flies weird. I guess I am way to spoiled with my 3DHS planes
Easy build, changed landing gear, reversed wire landing wire and installed 3" Dubro micro sport wheels for flying off of grass. Trimmed out with max servo travel the adjusted rate and expo to recommend settings in manual. Used 110mm as CG point with Glacier 2600 mah 30C battery installed. Flew plane in 5 to 10 mph wind, on low rate with no issues. Roll rate still to high for low rate and or a 45* upline inverted needed more down elevator then use to, need to adjust battery. No add weight added to aircraft. Need to try 2200mah as recommended. I also needed up elevator trim at half throttle to keep nose from dropping. Nice flyer lookin fwd to more fun.
I have several flights on this model and I must say that it is getting better with each flight. I did have some repairs after maiden because it suprised me. It needed quite a bit of up elevator to trim but has flown superbly ever since. I also added a hobby eagle a3l to add to my confidence. Now she flies where she's pointed even in heavy winds. Great bird for getting into pattern flying. Enjoying continuing great service com Motion RC.
Easy to fly pattern type plane. Unlimited vertical. Smooth rolls. Unlimited knife edge. Easy to land. Slows down nicely. Very stall resistant. Flys great with 2200-2600 mah battery. 2200 all the way foward 2600 all the way back. Be sure to set the travel limits exactly as the manual recommends. The ailerons have to be dialed back quite a bit. Then set the dual rates and expo as recommended. Quite docile on low rates and not overly sensitive on high rates. Anyone who is proficient on low wing 4 channel should be fine. Great buy at the price. If you enjoy smooth non 3D aerobatics this is the plane for you.
