Hi Arxangel. I juz maidened the plane and found it yawning to the right a lot when ever I throttle up. Indeed, it made it so hard to take off for me, when trying to fly it from a running track with a lot of obstacles around me. Btw, may I know how is the 3D printed motor mount worked for ya, and what is the best setup that you have experimented so far for a decent one hour flight? And btw, is it possible if you could send me a file for the 3D printed motor mount, cuz the nose down problem is killing me! Thanks a lot and I wished I had seen ur thread earlier!

I was writing without some hurry, so I don't explained so well. In Spain, people use the glyder wings, to avoid the plane to "fall to side when stalling" and also to have this "head weight" problem. Problem is that I'll have to make some modifications, installations, tests,... and my time is not enough, if I also have to do more major modifications to make the plane fligt as expected... Am I explaining well? It's just I "want" a plane RTF (RTF= modyfing servos, motor,... but not wings, or doing 70 tests to make it fly).
I read a lot of the Mobius, but as I have the GP and the gimbal from the multirotor, I just want to "use" it, and not have it inside a box But I'm trying my partner to buy it, and then if I like, I may try
Do you think they will upgrade to T-Tail? Because in a foamy you may modify the tail, but in this PP... I don't think you can do that at home!
For FPV, first is an autopilot with RTH function, in multirotor, in plane, in everything, now prices are so low, and it's a plus in security, also to start testing and then improving. The thing about 2 cameras is just a matter of comodity, video from GoPro for FPV is not the best, it's so modified and it's difficult to land. From the mini-camera, what you see is what is, so it's easy to make a fly.
About the Cat... yesterday I was flying, for first time in last 3 weeks, the horn of the elevator servo broke in fly... I'm thinking in buy today the Ranger, or buy a new fuselage, because this one is reparable, but... too much to do! A new point for good servos!
I have the Taranis with the Flaperon mix to slow it down, but I think it need to much more weight, with a 2.2A 3S battery, it can glide for 50-70 meters without throttle, and without loosing control, I was going yesterday to test flpaerons, but I couldnt
@Arxangel, any news on buying your upgraded motor mount?

Actually the Ranger is NOT easy to stall, especially if you have an AP stabilizing it.
As for the motor mount, as of this moment I can tell you that it allows mounting of a larger prop, and possibly makes the nose down issue a little less pronounced, but I can't say that it doesn't introduce other problems, because mine seems to have developed a right yaw in the air!!

I just think you 'll have some difficulties to find an RTF model that flies 'perfectly' right out of the box if you double its dry weight (MTOW at double of the standard weight), and that's what you are doing with your FPV stuff, electronics & batteries.
If your friend buys the Mobius, you will certainly want to have one too... and getting the GP out of the box for your field vids.
Concerning the T-tail, I have no idea if Volantex is intended to make one.
It shouldn't be that difficult though as the tail and stab have nothing to do with the PP fuselage. Tail and stab are EPO bolded together w/ some ABS parts.
I don't have a Ranger but I'm planning of building a T-tail (w/ integrated servos) that can just be bolted to the Raptor V2.
Sad that you damaged your Cat badly. If you go on with it, a nice choice of servos are the 929MG from Corona ( I think Arxangel is using them too following his reviews). Analog but strong and efficient. You can always use the 939MG (digital) for the elevator if you prefer.
The last versions of the Trainstar (trainer plane also from Volantex) now have a 15-17 gr servo for elevator. That's maybe also a way to go.
I believe that 'flaperon'-mix is the way to go as you can adjust it the way you want.
If the gliding ratio is really too important, the ultimate solution would be installing 'airbrakes' next to the fuselage but as I understood you don't like to 'modify'...
Good luck in repairing the seaplane
