    I like your designs so far. I do think you are underestimating space needed for pilot to operate the plane, as well as fuel storage. Also, for such a small plane, launching a single AMRAAM missile would be a serious offload, and balance problem. At least it seems to me like that. Increase in 10-20% overall size would be a must in my opinion.

    otherwise, i love the idea.

    I kinda agree. I have a plane in 3 views that is just marginally smaller than Helwan HA-300 and slightly bigger than Folland Gnat…and have radar and twin engines and 6 missiles inside. But there is a one measurable fact that explains some of it; the air intake routes are much shorter. So the internal volume is not “wasted” on routing the air inside…hopefully the air speed is still manageably reduced to reach the super cruise by the offset to get the stealth feature in it. Also the nose cone is generally empty in many older jets.

    The CG in this kinda lay out is pretty forward and a three piece wing ( like in Avanti Piaggio 180 ) is a stable platform ( enough leverage to cope with any situation ) when fly by wire is computer adjusted like in any stealth ( 4-5 gen ) nowadays. Certainly this needs a CFD ( computational fluid dynamics ) analysis and several aviation engineers input to get it further.

    Thanks for your comment !

    Size is relative.

    Here is a miniplane for 6’4” pilot and the GM-2 stealth.

    Certainly GM-2 could grow 10% bigger when all constructional details are solved. It is still small..or could be smallish. :eagerness:

    Here is a small airsuperiority fighter with 2 x J85s and F-35 in comparison.

    1/10 the cost and operating costs..less versatile ordnance and less effective radar but also less RCS ( which compensates )….and no VTOL option.

    200 MiG-31? 😮

    Well since the Versailles treaty was longer prohibiting and you get planes for free..then I think 200 would have been AOK.

    Seriously wasn’t Mig-31 obsolete already in 1991 ?

    Originally they offered A/B MLU, then when F-18 entered the competition they switched it to C/D.
    Finnish requirement was that planes were to be assembled in Finland, to gain technical familiarity with them, even though this increased cost of the contract. When General Dynamics picked up that they were losing, they offered a discount deal where planes were assembled in USA, but it would have been substantially cheaper option. This was very attractive given that the country was in severe depression, however even this was rejected. F-18 won largely because its best radar, longest service life and lowest attrition rate – combination thereof made it actually cheapest option over entire lifespan. Also, it was probably much better suited for road bases than F-16: Swedes came to same conclusion in the ’80s. Swiss also chose F-18 (so did South Korea before GD bribed them), so result of the competition was not a huge surprise for the people who were well acquinted with matters. Gripen was more expensive than either and also could not have been delivered in required timespace, Mirage was even more expensive. MiG-29 had very low service life compared to others which made it very expensive over projected service lifespan, also at the time there was no missile available which would have fulfilled Finnish requirements.

    2025 is looking increasingly optimistic. There has been talk about modernizing the Hornet and giving them 5 to 10 years more service life.

    It could have been interesting if Boris Yeltsin and if Kekkonen was still alive having made a deal to get 200 Mig-31s for free…it would have immediately meant that Sweden would have acquired 500 more Gripens and possibly bought 200 F-15s from USA to get back up before Gripens were delivered and operational.

    In the middle video of the three above they claim the 3d thinking is buried deeply in the operators of the 3D programs. I wish this was true. Many times the operators of the 3D programs are not the best 3D thinkers..but they sure can make your 3D idea appear very quickly on the screen.
    Naturally there could also be a good 3D thinker among these operators. I think the designer must know what the thing looks in 3D..these operators who use these programs are mainly intelligent workers familiar with 3D. 3D modelling is a good tool ..almost as good as a scale model.

    Hi topspeed 🙂
    The S**** SA-8 Skeeto by the famous Ray S****. A ultralight even before this class existed, it first flew in 1957. Understand the aircraft was tested with at least 8 different engines in the 2,5hp to 25hp range. Have no idea whether it is true, but read that the FAA only allowed flights not exceeding 50ft altitude. Originally N6048C, later N45682 and reportedly later donated to the EAA (AirVenture) Museum.

    Yes wout..it is Ray’s Skeeto !

    Go ahead with a new question !

    The maker has also been producing several “world smallest” airplanes..not the current.

    It was able sustain level flight with engine just above 3 hp.

    Indeed it is.
