Review by: Richard EdmundsThermal Hunter 2
This is the second half of my review. As stated before, I have used 3mm nylon bolts to secure the fin/rudder, which works - passing through one side of the fuselage, through the fin, and into a captive nut in the other side. I decided against making each wing in 3 parts and feel that was a good choice. Be very careful with aligning the wing joiners, as one of my wingtips was at the right dihedral angle but the root ribs were not perfectly parallel when assembled. I was able to very carefully bend the piano wire a degree or two and itís now a perfect fit. Thanks to other reviewers I was able to avoid the mis-aligned fuselage that was a problem for some. Corona DS843MG were fitted in the wings and seem a quality servo. Bags of space in the nose for radio and flight battery, which was used to adjust the C of G.
Yesterday was cold, sunny and still so was ideal for maiden flight. Test glide from the hand went about 40 to 50 metres first time - wow. Next was another glide launch and gentle power on, which resulted in a 45 degree climb out. At present Iím on a 980kv motor on 2s battery driving a 12 x 6 prop as I plan to mainly use this as a Slope soarer for very light days. After more use I may go to 3s and/or a 1200kv motor. Overall a fantastic quality kit and terrific light wind performance - I just hope that the flaps are effective to bring it down!

The balsa wood and laser cuts are top quality same a presentation , coloured plans... A joy to watch.The cardboard box is not top, could be buch better, arrived with a puncture that didnt affect the wood. Im actually finishing a 5 meters Minimoa, my next bulding will be the Inside-F5J that Im almost sure will be a pleasure.
Hyperflight was quick in delivery, top service, will buy again.
We have recently improved our boxes, so there is even less chance of damage now.
Also note this customer is in Argentina so the box did go half way round the world.
Review by: GordonInside-F5J
Soundly packaged and swiftly supplied.(Standard, first rate, Hyperflight service).
An excellent kit with clean laser cutting of well selected materials.
Still in the building phase so no flying comments; spent a little time considering wing washout as none is specified by angle adjustment of the wing panels. Concluded from review of other builders on rcgroups that none is needed beyond that built in by planform, tip plate, and possible section change along the wing span.
My only minor gripe would be that the instructions supplied are in German - although it is easy enough to find the translated version on line, - but it runs to rather a lot of pages to print if you want hardcopy.

Bought to replace very old rudder/elevator model. Superb quality materials and beautifully laser cut. Very simple and quick build but enjoyable nonetheless. Decided to go for the removable tail to minimise transport damage. When I came to fit the fin, I realised that with two nylon bolts straight through the fuselage and fin I could modify to make the fin removable as well. Just about to start the wing construction and am considering whether the outer panels could be made in two halves as lightweight wings with dihedral are always tricky to transport. Planning to fit Corona DS843MG servos. Canít wait to get it in the air

Can not review because have not got the package since 6/25/2018.
Review by: Sandy Colquhoun
Top quality materials, assembly over the plan on the building board is very quick, very small inconsistency between the plan and the interlocking parts, particularly wing rib spacings. I replaced the wingtip alignment dowel which is shown as steel, with a wooden dowel. The wingtip retaining clips have been discarded in favour of R clips inserted through 2mm holes drilled through these dowels(Modelfixings).The fuselage builds straight and true over the plan, however care is needed when covering to ensure that the film is shrunk evenly both sides and top and bottom, otherwise the very light structure will twist.The wing is much more rigid. CG is correct as per instructions, and flying is straightforward. Good performance, not a cheap kit, but a quality build and nice to fly .

This model is very well constructed and I am pleased with the fast delivery
Review by: Richard ShagamQuality kit
This is a quality kit. All parts are well--marked and arranged logically on the supplied balsa and ply sheets. Absolutely perfect laser cutting. I've only just started the build, but I don't see how this a/c won't just fall together and fly itself.
Review by: Oleg ZhmylevInside-F5J 2.9m KIT
I am very satisfied - fast delivery, high quality kit. I'm sure the model will fly great. I Immediately started assembling. :)
Review by: Lloyd DaviesInside-F5J 2.9m
I am so pleased with my Inside F5J. It is really cheap and flies superbly. Running 6 servos independently in the wing and only a 3s 1300mAh battery. I regularly get >30 minute flights from flat field. 40 minutes the other day and had to force her out the thermal. Everyone at the field likes this model and have been around gliders for years. Very pleased and well worth the money and building effort. Would buy again.
Review by: Robert SmithInsider F5J
The Inside F5J is a great kit to build and for the most part is user friendly. All parts are well labeled, laser cut and fit together like a watch. Having built two of them I can say that the only difficulty I had was trying to keep the long fuselage straight and true while building. It is very difficult to get it rite the first time and you don't get a second try. Be sure you build over the plans and pin down as you go. I found it easer to sheet the top of the fuse first while having pinned the bottom to the plans.
Review by: Efrain VilaInside F5 J
The Inside is a beautifully manufactured kit. All parts are excellently laser cut and the balsa is also excellent, and so are the plans and instructions.
Will start building soon and look forward to an easy and straight forward building process.
Review by: p9o1r1sche
Ordered this from Neil and it was shipped the next day. Very good service. I am still building the kit, so I can only comment on the box contents. Wood selection is good. Laser cutting is excellent. Parts fit is excellent. I am using the English version of the instructions and it has been very clear. Lots of photos help, too.
I would recommend this kit as an excellent build project and considering the comments posted on RC Groups, it should fly well.
Overall, two thumbs up! or five stars, or whatever.
Review by: Mike VosPopular Inside F5J
The kit is easy to assemble and every part fits very precise. Not completed yet but it builds fast. Just download the English manual and there are loads of info on the web on this model.
