X-725 M1 cpx

30.4k Hyattorama  6.3 years ago

This coaxial heli is based on Leehopard’s X-725 coaxial helikit (who did an amazing job, by the way). I added a detailed cockpit by Sarpanitu, some functional rear doors, some exhaust smoke, and infinite fuel (I’m not big on infinite fuel but I had to for flight characteristics). This is the mk.5 basic cockpit that has active view angle in [cockpit view]. This aircraft doesn’t quite handle as well as the original, but I think it’s pretty close...

Ag1- active view angle in [cockpit view]
Ag2- strong gyro
Ag3+landing gear - open/close sliding doors
Ag4+landing gear - open/close hinge doors.
Ag7- 3D mode (more aggressive collective pitch, inverted)
Ag8- weak gyro
VTOL- collective pitch
Trim- trim.

I couldn’t figure out how to hide the pistons that open and close the sliding doors (without immediate breakage). If someone is able to help me with this or help me learn how to do it, that would be swell. Hope y’all enjoy it!

Edit: the reason I put the head tracking lock-on cockpit in this helicopter is because I was putting guns on it that follow. But it’s not done yet.

    You’re the best! Thank you :) you’re a much more advanced builder than I am, but please let me know if there’s any way I can return the favor. @Leehopard

    Actually, come to think of it... I don’t know if I have the knowledge to be able to give you meaningful specs... I thought I’d build the shape, weight, and scale of the craft around the rotor assembly. Do you have a set of standard-ish dimensions that you would use if you were building your own small/ultralight heli? :/ @Leehopard

    Ah, okay, cool! Well thank you so much, I’ll get back to you on those specs. @Leehopard

    @Hyattorama I don't have but it's easy to make so I can give you if you want
    I need detailed specs to make it, like diameter, max lift, scale of mast, etc..

    @Leehopard hey man, I am tagging you here because I wanted to tell you that I am extremely impressed by and love your rotorcraft and helikits! This one is something I made quite a while ago, and I feel that my building skills have increased a lot since then. I feel I am ready to build my own heli but I am still not skilled enough to build a functioning rotor assembly with swashplate, cyclic/collective etc. I want to build a tiny/ultralight heli, so I wanted to ask you; do you have any 2-blade single rotor helikits? Thank you and keep up the amazing work!!
