Cobra ll

Received my plane in great shape. Good looking bird. The build went very well and enjoyed putting it together. Couple of issue that should be noted. First is the canopy. Seems to me they could have had a better system to secure it better. Lost mine In flight and wasnt able to find it. A latch design will a better way. Second is the battery straps are really long and the esc is just laying there. Needs a better design where the esc sits underneath the battery with wood or plastic devider between the two. Now granted there isn't much room for a 4s battery and esc the way she sits now. My 3s has enough room for any improvements. Now I like the tri cycle landing gear. Kinda give me a break from tail draggers. Also the gears are good and strong. Overall this is a good flyer and she gets plenty of looks out at the field. Trick is being patient with this one and she will give you great rewards. So with that being said she's not for a novice flyer. Again mrc rocks. Thanks guys.

Cobra II

Be sure your CG is correct. They say a nose heavy plane flies badly but a tail heavy plane only flies once. I was tail heavy and took off on my maiden flight went straight up, did a couple of back flips and came down. It will fly again but I learned a valuable lesson, CG is very important. Can't wait to try her again, maybe today. I love the plane. I have replaced the broken parts and it's ready.

Not sure what to say

Love the looks of this little plane. Flew great until....full up elevator made the plane roll full right. Darted right into the ground. Was fast...

Got my first flights today with this birdie, what a blast! Flew 6 packs, 2200 and 2650 4s. Absolutely rock solid little plane, it flies bigger than it is. Speed and acceleration are impressive, and it handled the 10-12 mph wind I flew in really well. Great vertical of course. Looks great low and fast! And it has a little whoosh and whistle as it hustles by. I was stunned when I hit flaps for the first time, and just floated into a perfect landing on the first try...really slow and stable with full flaps, makes for easy landings which should prolong the life of my landing gear. I'm really glad to see the P-39 modeled in this size, it's really got an interesting history, is a beautiful plane, and a really slippery shape. I do intend to go with a 2 blade prop (11x12 is what I hear suggested) and maybe some more powerful packs. But stock out of the box this thing rocks!

Crazy fast electric

I challenged on of the others in my flying club to a race with our P-39s. We agreed not to change the motor, ESC, or the body profile. We both decided to use a 6S 3200mAh LiPo. He used an APC 10x10 prop, I used an APC 11x12 pattern prop and installed airspeed telemetry. Both of us reached level speeds over 130 mph!!! On takeoff I went to a strait vertical climb and reached 75 mph before it was just a speck in the sky. Even at speeds over 100 mph it can stand up to hard turns that I even thought would rip the wings off. I do recommend if you are going to try to hit these kinds of speeds you separate the control surfaces to replace the foam hinges with hinged nylon. Overall I spent less than $30 to take this model from stock to a heart pounding monster!!

RocHobby P-39 High speed

Put the 11x12 two blade prop on and go ballistic. What a blast. Lots of ground clearance and the trike gear works good. Thanks Motion RC.

Nice for intermediate pilots

Airplane is quick to assemble w/o glue and very pretty. Nose gear looks fragile due to it's length but due to thick shaft it's surprisingly robust. I'm using 4S 2800mah battery at the recommended CG and a gyro. Flight time is about 6 mins of mixed flying. If flying on a windy day, gyro is highly recommended. I've flown this bird twice and botched couple of landings, surprisingly not the first few. Balanced according to stated CG the airplane flew initially with almost no trim adjustments. I started with 50% elevator and 70% aileron and just needed few clicks of down elevator. Retracts and flaps operated without any problems and the airplane was agile but not too speedy. Take off and flying is straight forward but landing with flaps can be a challenge as with any high performance plane with flaps. Must maintain speed, otherwise wing will start to wobble and end in a less than stellar landing with possible damage as it happened to me. Main gears will take the punishment but nose gear, however robust, will bend. Due to thickness of gear wire, in order to straighten it out, retract unit must be disassembled to completely remove the wire. Use caution if you do so not to damage the fragile motor wires and it's connections. I would recommend this airplane to low wing high performance proficient pilots.

Awesome

If i could rate this plane 7 stars i would. I got this plane about 1 year ago and it had been sitting on my shelf collecting dust. Last weekend i decided to take it out for a spin. I thought this plane would be very hard and challenging to fly but i was badly mistaken. This plane is the best one I've had in the 30 years i have been in this hobby. It's takes off and lands like a beauty but don't bother using the flaps in air because they screw up the trim. Love the plane though.

Nice Plane!

Plane was very easy to put together and had no issues with the parts or assembly. The maiden flight was beautiful with very little trim require. I'm not sure if the plane is as fast as it states, I'm using 4 cell 2200 40C lipos and getting around 5 minutes. It's a perfect plane for the parks as long as the grass is short. I haven't hand launced her yet and not sure about it due to the weight. The plane does have some weight to it.
