Review by: Florian DNRJ Strong kit
This was my first purchase from Neil / Hyperflight, and I can only confirm the super communication and fast shipping (to Germany in appr. 7 days).
This is a Kit of high quality, but you need to keep in mind you need a few extras, like hinge gap tape, wire for making small hooks / linkages (recommend 0.3 mm for the tails, 0.8 mm for the rudder/elevator at the servos in the front (rudder/elevator))
Although I am doing aeromodeling for about 35 years now, this is my first DLG, so I had a few challenges with the linkages and the overall small size of the nose area. But now it looks like a Swiss watch and is awaiting the maiden.
Thanks a lot Neil, this one is going to be fun!
Review by: BrianNRJ
I've been flying R/C for around 40 yrs but haven't quite made it into the old farts group yet. I'm very competitive by nature and flown or raced most disciplines to a decent level including 3D Helicopters and Drone racing! I'm a self taught pilot whom started out Slope-soaring back in the day so gliding has always held a fascination.
I choose the NRJ as it had a good competition record and even contacted Pierre Meunier to see if his opinion still stood for the NRJ. It did.
My NRJ arrived in a substantial cardboard box and well packaged, thanks Neil ;-). The last composite models I have to compare it too would be Pike Plus/Pike WR F3F &15yr old DLG so it's has been a while.
The finish is very good and the frame is light and and sleek everything I hoped for, but I had a lot to learn on this build as F3K construction has changed substantially. Spring controlled Rudder/Elevators and quality servo's these days..mmm. It's a very tight build and the instructions I found lacking and setting up the control runs left a lot to be desired and frustrating experience.
I'm still not 100% happy with my control runs due to very minor interactions due to proximity to servo's/Horns in the cockpit. The only thing during the build that needed any real adjusting was the Servo Tray which required a lot of sanding to prevent the inner nose expanding slightly interfering with the Nose Sheath fit (check before Gluing)
My own personal hate is programing OpenTx transmitters and this has proven to be the case and did spend quite a few hours messing with SOAR OTX. I ended up going for a more conventional OPenTx programing which I've still to complete.
A more seasoned Pilot and modern F3K Builder would likely breeze through all of the above considering it the Norm.
At the time of writing the weather is unsuitable to maiden + Covid restrictions mean it will be a few weeks before I can fettle her in. BUT I dont expect the NRJ to disappoint.
Review by: Jack G .NRJ - fantastic!
Iíve been flying RC for over 30 years. I got back into DLG flying 5 years ago and Iíve owned a flown a lot of the top models( BAMF / NXT/ CX-5/ Falcon. I tend to keep my models for about two years and I fly a lot- weather permitting. I decided to give an NRJ a try as Neil / hyperflight had a new shipment arriving around Christmas.
I ordered a standard layup NRJ in bright red- it arrived amazingly fast in three days from the UK to Pennsylvania via fed ex. I built it over two days and was out flying the second day ! The build was easy and went together fast- the servo arrangement and linkages are a bit confined ... but it wasnít too bad to complete. I used all of the included hardware and everything was perfect.
I set the CG at 65 mm and took it out for a maiden flight.....on the third throw on a cold overcast day I managed to hook some light lift and rode it up to 120 meters I decided to come back after a 7 minute flight!
I flew it again today in calm overcast conditions and had at least 3 or 4 flights over 5 -6 minutes in the span of 40 minutes on a cloudy overcast day.
I am really impressed with the performance and launch height- the design is very efficient and I felt very comfortable with it from the first flight- ( I tend to fly a bit faster than most and live faster sportier ships) I liked this one from the first flights and I imagine it will only get better with more flying time and tuning.
Thanks for the excellent design team OA and the excellent service Neil and Hyperflight!
Review by: Tom LFlys great, but building is very frustrating.
This is my third DLG purchase from Hyperflight and things started off the usual way. Great service from Neil and speedy delivery on the order. The model was packaged really well and was really excited to build. The quality of the parts is good but I have seen better. The colours (i.e. the white) could have been little brighter (i.e. white looks a bit greyish) but nothing that would ever make me drop a rating point. The wing however had an issue where one of the flaps was sprung (i.e. always wants to point up). Not great but not horrible either.
The build of this model is where things got disappointing. The hardware package supplied with this model was incomplete and some of the materials where completely unusable. The tubing and push rods supplied for the flaps/ailerons had so much friction when you tried to move them they had no business being installed on this model. One set was practically seized and the other one had way too much friction. Although there is music wire (for the tail surfaces) shown in the picture of what will be provided my kit was missing this. When you spend this much money on a top end DLG I think it is fair to expect proper quality materials and for it to be complete. With hobby shops closed or poorly stocked during the pandemic it was difficult for me to find replacement parts.
The instructions that are available could really use a revision to make them clearer. As it stands they are more of a collection of thoughts on the assembly of the aircraft rather than step by step instructions. The horn supplied for the tail for some reason is too long and needs to be modified so it will fit. This is in the instructions but in my opinion is not clear enough. This begs the question, why wouldn't the model ship with the correct horn in the first place? I have built many models but this is the first time in many years where I had to redo several steps to get the model to work.
The linkage connection is not easy at all to do. Aside from missing parts it takes multiple attempts to get the required range of motion while not interfering with the movement of other servos. The method of securing the servos is certainly innovative but the elevator and rudder servo does not have a direct clear path as the flap servos are directly in the way. I think more work is needed to refine how to make interference free connections.
That said it is a beautiful aircraft once you sort the assembly portion out. It flies as described and launches and penetrates really well. I caught some great thermals with it today. I think with more work on the linkages, a complete hardware package and better instructions I can see giving this plane 5 star review status.
Review by: Mark PassinghamNRJ DLG
My first modern DLG having been flying an original Longshot I built in 2006. My expecations were very high and I was not disappointed. I fly on a fairly windy common with a lot of gorse and bushes so I went for the strong version. All the components are beautifully finished and wings are impressively rigid. The online instruction manual is excellent which is a pleasant surprise and almost everything you need is included. The crimps are a bit on the chunky side so I used Hyperflight's own and the only other thing I needed was some wire for the end of the rudder and elevator cables.
The plane came out at 230g with a FrSky XR4 and a Radient 1S 600 mah lipo in the nose. Space is pretty tight so I cut the plugs off the servo leads and soldered them direct and had plenty of room. My only real complaint is the nose cone is very flimsy and I damaged it first time out. My model needs a bit of lead in the nose so the nosecone could have had an extra layer of glass cloth.
Flight performance is excellent. Launches are a doddle even for a beginner like me and the speed range of the model is impressive. With no camber the plane penetrates very well and with the camber deployed it floats beautifully. I am still getting used to it and a bit of tweaking still required to get it setup to suit my flying style. Second trip out and my best flight was 12.45. The plane really responds well to lift and doesn't need much to climb.
Very happy indeed and no hesitation in recommending the plane.
Review by: Mark
Superb model from Anton. The finish on these planes is the best Iíve currently seen and Iíve tried a lot of other models, I have the strong layup and wing finish is like glass. And for a strong layup, my model still comes in at under 220g. Builds super fast, I had 80% of mine built with 2 hours of getting home from collecting.
The nose is a bit tight for space, but I can confirm that with a 350-380 sized 1s lipo that both the Spektrum ar410 (decased) and the Frsky G-RX6, RX4/6R fit nicely. With the Frsky rxís you can get a 600mah gumstick shaped Turnigy Nanotech in there. Once released I will test the new Spektrum 6610T.
Overall a superb plane, coming from planes with 5.5 degrees of dihedral like Snipes, the handling takes a little getting used too, but I heard the same about the Flitz that Hyperflight also stock, but once you are comfortable with the plane itís a serious weapon. The speed range of the NRJ is impressive too, pretty fast plane in Speed mode yet slows up nicely with 6mm camber and goes up in lift very well in this mode.
For me it took some time to bond with the plane but I would definitely buy another.
