Dynam Primo with Gyro 1450mm (57") Wingspan - (Ready-To-Fly) - RTF - DY8971SRTF

This is the new Stabilized Ready-To-Fly version. This model comes with the Detrum MSR66A 6CH 2.4Ghz Mini Receiver with iStone 6-Axis Gyro/ABS built in for auto-stabilization and recovery.  For more information on the MSR66A click here. The Dynam Primo with its giant tundra wheels is a great high wing trainer molded after the super cubs the gifted bush pilots of Alaska might use where taking off and landing in less-than-ideal runways is a way of life.  Needless to say, this is a trainer that can accommodate virtually any flying surface you may require.  And what bush pilot would ever dare such treacherous runways without flaps?  The Dynam Primo includes working flaps to minimize your takeoff roll and landing roll out if space is a concern.

Powered by a BM3720A3-KV650 brushless motor and Skylord 40 Amp ESC the Primo packs a punch for a wide range flight envelope and for pulling out of trouble when you need it, yet offers outstanding slow flight capabilities for those newer to the hobby.  

The RTF version includes a GAVIN 6A 6 Channel radio, Detrum MSR66A 6-Channel 2.4Ghz Mini Receiver with iStone 6-Axis Gyro/ABS, 4 Cell 14.8V 2200 mAh LiPo battery and charger so everything you need to fly is included right out of the box.

I have not had this flying as it is winter...wehave snow...the instructions were not very good to assembling.

Steerable tailwheel becomes very loose in the foam setting after one use, almost no instructions for assembly(thankfully there is youtube), flaps are loose with a lot play and the control anchor horn is loose in the foam. Speaking of foam, the wheels are made of styrofoam and they are white, not black. No manual or instructions for the battery charger. Its my fault though for assembling the plane, should of just sent it back. I'm still kind of new at this hobby. It flies ok though. Nothing to write home about.

A lot of plane for the price. Have not flown this plane as of this review, but will give it a work out when I do. Had a bad charger with it but Motion sent a new one with out a problem. The wheels are white and the picture show black ones. As long as they are not flat , no big deal.

Dynam Primo With Gyro

The plane was delivered undamaged and in good condition. Packaging was very good. The plane also fly's very nicely has lots of power and is easy to control with the gyro. It is also very durable for a foam plane and has good reinforcement incorporated in it. The only minor thing i didn't like was the wheels were white not black (I had to paint the wheels black), and Chinese directions to bind the receiver were very poor and meant for another receiver all together. Had trouble binding the throttle. The flaps were difficult to set correctly I blame that on the ****** Chinese too. Other than that it is a really strong sturdy plane and fly's very well with lots of power and was a great price.

This purchase was my first aircraft purchase, but only gets a "3" for now. I have not flown the aircraft yet, but have lots of pre-flight problems. I am not new to r/c aircraft, but consider myself somewhere between beginner and intermediate. Problems for me follow: 1. Directions are almost absent, suggesting new owners must find their way. 2. Initial battery charging was a flop for me. No instructions came with the package. I contacted Motion RC on their "chat" option, explained what I did and what happened. Long story short, they send me a new charger with printed instructions. After following instructions I found the new and old charger worked just fine. 3. Binding - Literature that came with the aircraft and transmitter did not provide easy-to-understand instructions. So, I went back on "chat" option. Instructions from Motion RC were simple. Binding was easy. 4. Wing has four electrical connections. Two are for ailerons and two control flaps. Easy to sort out, but instructions would be better. Ailerons were easy to resolve with the transmitter. Flaps were my problem. Transmitter has toggle switch for three flaps position. None, 50% and 100%...I guess. 50% position is just fine, but 100% drives the flaps past 90 degrees. Move back to 50% and flaps don't move. This is something I can resolve with push rod and servo arm position. Motion RC should have shipped the aircraft with correct flap adjustments. 5. Battery position - Battery is held in place with Velcro. That's fine. Battery must pass through and angle down a narrow hatch on the top of the aircraft nose. Velcro hook and pile don't slide across each other very well. Again, no instructions on how to position the battery into the aircraft. I fabricated a thick but flexible narrow plastic strip to slide between aircraft Velcro pile and battery Velcro hook. This works fine. More to follow...

Shipping was fast, screws were not labeled in the bags, my tires are solid white, I'm looking into painting them black,, connecting wires for all surfaces were way too long, had to screw the clevis in as far as I could to level out elevator, ailerons and flaps, the plans are not for a beginner to put together, safe flights to all

Dynam Primo RTF

The only thing I can say good for it is the cost for a RTF and getting the transmitter/receiver, motor etc. is a good deal.... But this plane must have been put together on a Friday...........The nuts that hold the wing on was not in place, they were on the bottom of the planes fuselage, had to cut into the side to get them into it's place to put on the wing. (you could not attach the wing bolts.) The elevator and rudder were in the wrong area on the receiver. The flaps would not work right. The aileron and flaps would work together, ONLY right aileron up, right flap down.. could not ever get the receiver and transmitter to work with the flaps....(disconnected the FLAPS. The decals, I do not know what airplane it goes on..........Not this one. ALL in ALL, after getting everthing right, it did fly very well. (stay out of the wind) What I am going to do is try to mate the receiver to my DX-9 In a nut shell........after getting it right, it is a good airplane....Ben

Haven't flown it yet but I believe it's going to be a fun bird. Had a warped very stab but the guys at Motion RC shipped out a new part very quickly.
