Mine weighs about 1500 grams and flies great. I’m running a 4S 3000mah on the standard eco power setup.
Enjoy your Edge.
Sorry for the confusion.
80mm back from the leading edge of the top wing, which is approx equal to 0mm from the leading edge of the lower wing (the recommended C.G.)
Others have suggested that the C.G. can go as far back as around 95mm behind the leading edge of the top wing.
My next flight will be at 85mm. Will let you know how it goes.
Well, finally maidened mine on the week-end.
Ended up with a take-off weight of bang on 2600 grams, with a C.G. at about 80mm.
Can’t believe how well it flew! Required no trimming at all, and takeoff and landing were nice and easy.
I was running mine on 3S using the recommended eco setup. I was using quite a fat battery (Graphene 3S 4000), with the ESC sitting on top of the battery. This was a bad idea! After landing at around 4 minutes the ESC and motor were very hot, which I’m guessing is because of restricted airflow. I’m planning on extending the ESC leads so that it can sit under the front seat, and use a slimmer battery to improve airflow. This will move the C.G. back a little, but I think it can handle it.
Would be interested to see where others have positioned their ESC’s.
Thinking of trying her on 4S, with max throttle set at 80% to see if that is a more economical and cooler running setup.
Great to hear the MkIX Spitfire maidened so well for you.
I’m just starting on mine.
Do you mind letting us know what retracts you used, and if your are happy with them?
Thanks for the info. What size battery are you using that you had to use the 20mm extension.
Would a heavier battery allow you to balance without the extension?
I’ll post up some pics of mine when it’s finished.
I’m currently printing the same version. Did you get the decals from Callie-Graphics? Do they stick well to the PLA?
Thanks for the info on the tail wheel. Will have to research a solution.
When’s the maiden?
Has anyone tried using the 4 blade 16 x 10 prop assembly from the FlightLine 1600mm Spitfire?
Seems the size would be reasonably scale, and with the 430KV motor, should provide sufficient thrust.
Has anyone tried fitting the retracts from the FlightLine 1600mm Spitfire?
Yes please. A must have for the collection.
