Also, if you can make formers for 120mm so people can keep the options open and you have more sales

If the AUW was around 11 - 12lbs > 9lbs of thrust with really good efflux numbers at 100% FSA will push the aircraft around good and inexpensively = lots of sales

Kin,

Thanks for taking note.

Functional canards (pitch control), outer ailerons (roll), inside flaps (pitch and brake in combination with ailerons), rudder. Airfoil - capable of very slow speed (say 30's) to fast, not very fast (say 100 mph - you see, I am nearly 79 years of age).

90 mm EDF would be very good, though, I will not turn my back on 100/120 mm's.

Viggen please. I have the big Sapac Gripen (I know, not the same quality) so I'd like a Viggen.

If you go with at JA-37 Viggen you can count on a sale here, especially if it's a 90mm setup. I don't need it to be full composite, balsa built up wing or foam with balsa sheeted wing is fine with me. Again, I just ask that it be designed with electric retracts from the start as I won't do air or mechanicals any more and modding a new plane to fit electrics is a pain.

As to the size of of the Viggen, 1.75m seems too big. I just flew my RC-Lander T-33 and it's 1520mm long with a wingspan if 1638mm and it's as big as I'd go for a 90mm. Granted it is foam, but it's happy with a 9-10s 90mm setup and a 12s 120mm setup also works. If you did go with 1.75m what would the wingspan be at that size?

Also with the 1.75m size on 90mm it would need to be able to accommodate a 10s 5000mh setup without size and CG issues. If that becomes and issue I'm also fine with a 1.4 or 1.5m 6s-8s 90mm plane. It doesn't have to be SUPER SIZED. While I prefer 90mm if you went with a 70mm or a 100mm I'll still be a buyer but it seems that 90mm would sell the most quantity.

As to the JAS-39, I'd consider one, but it would have to be priced right, but I'll get the F-20 before a JAS-39 and I will definitely pass on the F-14 (just not fun to fly with the CG change with the swing wing).

OK ! size of the length 1.75 m just a idea now . of if the size back to 1.7 or 1.65 also no problem for me . ! Yes the battery and power set is a problem to matching the c/g .if size a little smaller in 1.7 mor 1.65m , i think the power set can smaller and total weight will less some . Keep to 6-8 s should be nice .In fact i don't like over 8s , Thw wing Balsa is ok . but i try make full composite wing in a lower cost . think a idea ! Ok I need to fins a detail and good precision plastric models of JA 37 , but i have two box JA 39 in hand but you like 37 . ok no problem , fins a plastic model and start to drawing . not cnc machine milling a very big 3.5m models . ait line models , but oem order so not post here .last week just finished a 1.85m full composite jet fighter .full body with former just 2.5kg .so i sure i can control the JA 37 fuselage weight in 1.4-1.5 kg , i think can possible target weight in full composite also 1.4 kg. now the sytem hawk fuselage just 550 g only . the wing are cutting in the hot wire cutting bload .. the retract gear mount is fit to my coming out ep retract gear .

Kin,

Deal! When do I take delivery?

Actually, one with e-retracts, one for bungee launch.

Perhaps, a third with turbine(?).

Two is enough for now.

BTW, I am not aware of any Viggen EDF other than the MBS kit. Hopefully, you will capture a good market.

Actually, if you do the JA 37 VIGGEN in 1:12 scale, span will be 90ish cm, lenght 140ish cm and The main wing is too thin for electric retracts. See my scale build of it. Bettet if it is 1:10 or 1:9...
Sincerely
