Are you looking for extreme speed right out of the box? If so, we've got you covered. The 100+MPH Radjet Ultra is here!
Extreme speed, easy assembly and wicked good looks, these three things sum up the all new Ultra Radjet PNF airplane! Constructed from durable EPO foam, the Radjet Ultra is one tough airplane, perfect for handling the extreme speeds that this model is capable of. The wing is reinforced with a large carbon fiber wing spar to ensure no flex during high speed flight.
The Radjet Ultra's potent power system is capable of propelling it to speeds up to and even exceeding 100MPH*! This model features an elevon setup with two digital metal gear servos pre-installed. The servos provide plenty of torque keeping the control surfaces in place even at full throttle. Simply put, this PNF model was built for speed!
The included brushless power system can be used with both 3S and 4S lipoly batteries. Two propellers are included in the box, a 5x5 and 4.75x4.75. You will need to use the propeller that matches which battery you will be using. For 4S, use the 4.75x4.75. 5x5 with 3S. Both setups offer excellent performance, however if you are a speed freak looking for true 100+mph speeds, you will want to use the 4S lipoly setup.
Be sure to check out the flight video above. We used the Quanum GPS logger to show just how fast this model can fly!

Haven't tried this one out yet due to bad weather conditionNot happy at all, the top speed was only 120km/h (75mph). The stickers was barely attached to the plane. Here's my review: https://youtu.be/8kkkhxC5RsACan't get her to fly. As soon as I give it power it just doesn't fly correctly. I tried tons of different setting and have concluded the motor or bec noside is killing the receiver but I can cut the throttle and it will glide ok. As soon as I give it power I can't control it. I think it goes full up elevator.
Been flying RC for 46 years and never seen anything like this. But then again I am using the cheapo Turnigy i6 radio. Maybe a different receiver could handle the noise better. It goes on the shelf for now. I am done with it.Quite nice package, but here is what I don't like with this plane: The stickers falls off very easily, one of the roderhorns were not glued in and the BIGGEST reason I dislike this plane: It is not a 100mph airplane. I used the Quanum GPS, and my top speed, with a new 4s battery, was only 74,5 mph!
My experience with this plane described with one word would be, disappointed.
Here's how to build it: https://www.youtube.com/watch?v=2yNEf_ue0ZIThe plane goes together really easily and everything was in PC when it arrived. I can honestly say this things is insane, its very quick and remember to dial down your throws if its your maiden and your going to get up it. Its response at speed is insane and I should have dialled down the throws myself. Third fight I was low and fast and must have touched the stick a little too much and a millisecond later it had banked right, hit a small stand of trees, broke a 1 inch sapling in half and peeled about half an inch from the trunk of another sapling all in the process of disintegrating. The damage to the plane was fatal, but the damage to the two trees was a little scary. Great plane though. Would I buy another, hell yes but dial down the throws.This plane is absolutely amazing. The speed it goes is incredible. Out of the box it is reasonably easy and fast to put together. Only thing is at 80 mph and above the plane is very responsive. Dial in expos about 30 for the ailerons and the elevator doesn't need anyI have owned numerous hand toss pushers throughout the years, the most similar to this would be a Stryker. I bought the ready to fly minus the RX. Tried hand tossing this bird 4 times, I even had a 15 foot drop off I was tossing over and two times it would belly land. Thought I would put some up elevator in on the next toss but it would stall and drop to the left or right. After the 4th attempt it broke the nose off. It just does not seem to have enough thrust. Static current on a 3S 45C 2200mAh battery was 33 amps. Not sure what to think but it didn't work for me. And yes I had the correct propeller for the 3S battery. Once again you get what you pay for Hobbyking, I should stick with the parkzone/eflite products.First flight with this plane was with a 170 degree view 600tvl micro FPV Camera situated in the cockpit at pilot eye level using a custom micro VTX and antenna. Having a pilots eye view was awesome, hoping to get an OSD to overlay the console in the cockpit view for a complete nerdgasm. Outfitted it with a 4s battery for the maiden flight, tons of power on tap and cruises along at a 1/3 throttle. Had a friend try to follow it with his 4s capi and he couldn't keep up with it :D
Product shipped missing a couple parts- HobbyKing sent out replacements that required modification. Bit frustrating- deducting a crown for that.I am not sure if this plane will fly on a 3s battery. I had to add quite a bit of lead to get the CG right and my first flight resulted in the plane gliding a short distance and coming down hard and breaking a prop. My other major concerns with this plane are the quality of the foam is not very good, the stickers/decals are not staying on and there are no skids on the bottom of the plane.wow this thing zips. running mine on a 5x5 prop. stock set up- with a 4s 1800 40c discharge no problems, 12 flights so far
