@@alanfan9989 great, thanks. I've got all servos installed now. Mine did not come with lights. I will be finishing the lighting installation this week. I should maiden her soon!
The factory test method is to use a hook to test CG. There is a hook tool provided. The instruction manual does not indicate CG mm. (The empty barrel of the main fuel tank is horizontal. The machine head will be heavier when filled with oil). Please refer to it.
@@alanfan9989 thanks, see page 43 in manual, CG=184mm... I moved the tank a little back so no CG change when full/empty so I can more easily set cg that fits for flight and landing without being nose heavy in one phase of flight. Your turbine seems over 25mm apart from straight section of exhaust tube, did you go for 30-,35mm? I am using the same k102, thats why I am asking, it is on the upper limit for that pipe, so if more distance helps to cool it, im there too :)
@@TomislavReskovic Your turbine seems over 25mm apart from straight section of exhaust tube, did you go for 30-,35mm? =>Yes. The distance between the straight section and the turbine port is about 30-35mm. There is no problem.
thanks for the info, I have just finished mine, 7kg no fuel, around 8.8kg takeoff full tanks... 10kg turbine, should be interesting SKELETON build ua-cam.com/video/wOG3AW90K84/v-deo.html
Great flight! I have the same Viper with a Wren 100. Was you nose gear door included in the kit?
Our local seller sells them together with the landing gear, jet pipes, and oil barrels along with the aircraft.
@@alanfan9989 that is great, do you have any contact information please? I am looking for a spare canopy and the missing gear door. thanks
smooth flight ..didi u using any gyro?
Hello. No gyros are used. As far as I know. Originally a TOC 3D pilot.
Great flight, beautiful plane. What servos did you use, I'd love to get some info on your lighting package.
servos: generally 10~20kg standard servos is ok.
lighting: LED are installed in the original factory.
@@alanfan9989 great, thanks. I've got all servos installed now. Mine did not come with lights. I will be finishing the lighting installation this week. I should maiden her soon!
@@alanfan9989 My maiden went great. This bird is awesome. do you have any pictures of how mounted your nose 😁gear door and the servo for it?
@@richardk302 Sorry. This is another pilot's maiden flight. I'm just recording the video.
What throws are you using on your flaps. They look like they are way pass the factory recommended.
The factory's suggestion is just a reference value. You can change the value according to your own flight characteristics.
Excellent flight
Wing spang = :2mts ?
Lenght= 1.9mts ?
Weight=10Kg include the Turbine ?
Wing spang = :1.9mts
Lenght= 2.0mts
Weight=10Kg include the Turbine = yes.
Question can this be flown on a 120mmEDF?
EDF can. Use 12s or 14s power. The flight weight is about 9kg (JET).
@@alanfan9989 thank you for the he response, I will be ordering me very soon.
@@skrub6969
Weight at landing with 0.5L of fuel is then around 1.3kg less than takeoff weight? 8.7-9kg landing? Niceeeee
Cg stock or 190, 200mm?
Thanks
