There is plenty of rad in the RadJet-800! With its amazing price, EPO foam and with great performance, this brilliant model has no trouble earning the RadJet moniker.
The Radjet 800 has been tested and flown to within an inch of its life and it performed flawlessly, not only in terms of light performance but also reliability and believe me, we tried hard to kill the test version! It has several impressively simple and practical features such as the plastic skid on the length of the underside of the fuselage that will protect your Radjet from the usual tears and gouges, servo arm protectors on the wings, effective cooling for the ESC & Lipoly and so on.....and its how much?
But, it doesnt stop there, oh no! Whats it like to fly? Utterly brilliant! The light flying weight means that the outrunner motor gives tons of performance, the Radjet will pull massive loops and is capable of some pretty precise aerobatics, its quick, no doubt about it but throttle back and it becomes a total pussycat, fly it like you stole it or glide around, either way its a hoot! So to sum up, it looks great, its easy to assemble, flies brilliantly, is reliable, fast and cheap....Radjet? You better believe it!

Hobby king is getting worse and worseGreat little plane for the money! I'm flying mine with a Zippy Compact 850mah 35c battery and it was easy to balance. I'm using the stock motor, but I switched to an APC 6x5 prop and it's pretty fast and vertical climbing is easy. Flies great, definitely worth the money!Very happy with my RadJet 800! Just one-day delivery from EU warehouse to NL. Actually this is my second RadJet as the first one got written-off by pilot error flying upside-down at low altitude... It was so much fun I ordered a new one instantly. I use two HTX900 servos and a Turnigy plush 25A ESC. Aside that you need two 12cm servo extensions and some foam safe glue, all available at HK EU.
With the standard 3cell 1300mAh Lipo you are slightly nose heavy, place the lipo as far back as possible in the canopy area. Trim the elevators so that the underside of the elevator is in the middle of the wing piece it mates with- straight flight instantly. I found it helps throwing the RadJet a little upwards, not flat as it takes some time to take up speed and it will sink the first few meters. FUN!On my second airframe of this little rocket. I really love this prop jet. On a 4S 1000Mah I get about 3-5 minutes of flight. On a 3S 1300Mah I get a solid 5 minutes. Once you get the CG correct it is a very predictable plane. I'm old school and have no clue how to set up EXPO and all that stuff even though my radio has it, Which is from HK too, so if my old butt can have this much fun with it, it is sure to be a solid design. I have had 3 wide open throttle nose down, absolutely horrific crashes with this thing, and another wide open encounter with my big shop. It will take some serious abuse, and with a little fiberglass tape, contact cement, and maybe a balsa splint here or there, you can go out and do it again.
This one is priced extremely well for what you get. I fly mine with the motor and props it comes with and it's a blast. I have a 3800Kv motor coming to see how much faster it will get. If I can improve my flight skills enough, the Red Head Pulse Jet engine I bought from HK as well, will be strapped to it for some no dubitably exciting passes.
BUY IT! you will not be disappointed. I have never even flown a plane this style in all my years and I can even keep up for the most part with the throttle pulled back a little.sehr schoen ausgefuehrt, auch Decor schon drauf. Material gut und fest, Teile passen gut. Seitenruder koennte man anlenken (waere vorgepraegt). Laest sich gut "tunen" - (staerkerer Motor und staerkerer ESC, 20A ist auch so etwas wenig)
Hoher "Spassfaktor)Klasse Flieger. Ich habe nach dem ich ihn vorgeflogen habe mittlerweile 3 weitere fuer andere Piloten geordert, und alle sind damit sehr zufrieden. Die Motorisierung ist voellig ausreichen.This little jet is absolutely a blast! This was my second kit of this plane because I had a servo failure on the fist one. They go together very easily and there are many options for modifications as you see fit. One thing that is extremely important is the CG. Watch the U tube videos and find what best for you. So far I am at about 390mm aft of the nose for mine with both a 4 cell 1.0mah pack and a 3 cell 1.3mah pack. I plan to move it even a bit farther back just to keep trying to find the sweet spot for me. I'm using the stock motor and prop with a 30amp esc. I can see adding maybe a little more power but as it is out of the box it's great. Very quick roll rate and climb. Buy it for sure! It is also surprisingly tough! I had a brain fart incident and flew it head on into my shop on final for landing, now power on but the glide speed on this is pretty fast. The only damage on it was a warped nose from the hit and some creases to one wing tip! Put a bit of glass tape on it and it's was ready for the next flight. Very happy with this plane>this jet is cool. I have the fastest one in the world. My setup is Dr Mad Thrust 2970 3000kv, YEP 150a esc (needs a bigger heatsink), turnigy 6s 1550 mah 65c ( that gives me two passes at 190 mph) or 4s 2700 mah 65c, i run 4s on a 6x6 or 6x5.5 but the fastest is on 6s with a 5.5x6.5 carbon pro. i get about 2 min on 6s and 3.5 with 4s. Be warned this setup is overweight and very overpowered hand launch straight up and it comes in very fast and has this tendency to cart wheel. Don't believe me. Watch my video. Caribbean's fastest rc jet world's fastest radjet. https://www.youtube.com/watch?v=5BK3T_gjO1QI like how small this kit is, packaging was good, I read disappointing reviews about the motor it comes with so I decided to go 4s after I reinforced the body but the motor mount didn't handled the pressure, after fixing I had torque rolling issue which can happen if you have too much thrust to weight ratio or high response on the esc settings (I used talon35) after the tweaking it flow ok but very sensitive to my taste I crashed it on high speed turn after getting disoriented. nonetheless if you want a fast pusher jet and you have the tools to make it 4s its blazing fast (some have converted to 6s as well for even faster setup) totally not for beginners or people not used to high speed planes as its small and hard to see especially on a cloudy day. I might buy one more and try again but I'm really interested more in the skyfun which flies great on 4s and can take more beating and have space for bigger battery. my 2centsAlmost perfect, you can fly it right out the box if you have the PNP-version.
I did some modifications to it. Added 1x6mm and 1x5mm carbon spars to wing through the fuselage and another carbon spar to the front end of the fuselage, elongated the cabin hatch and added rudders to it, 2x TGY1440 servos. Also I changed the servo links to work from the upper surface, no need for those plastic covers.
Stock motor and 3S 850mAh batteries, CG in 5mm more to nose than in the manual.
Easy to fly if you can handle a speed demanding model, starts wobbling a bit when you have too little airspeed, no problems with stalling with the front CG.
Flight times around 5 minutes (3S 850 again), can easily carry a Mobius. Relatively easy to launch and land with a long final. Rudders are a nice plus in the air, especially when having the camera onboard and chasing other planes. Snap-rolls are a blast ;D
