the white pearl - twin ducted fan hovercraft
hi guys the past year has been busy and the coming one even more crucial and exciting. so my coaching centre has given us a break of 8 days before the next brain cruncher begins and it so happens that it coincides with my schools holidays.
well it was my mom who asked me why dont you go and fly in these holidays. you see she has always supported me and also while i was busy in studies she had kept my funjet and easyfly dust free all this time.
flying the planes is not going to be possible since i have to prep them up like the funjets servo's need replacing the gears seem to have stripped and the easyfly the motor and prop have to be tended to since i although upgraded the motor but never got the esc ready so no flying but i have some relief for that.
so i decided to accomplish two things in these 4 days (rest i will be using for studies but will drop in here)
1. (Massive inspiration from VC bhaiya over here) the lcac just persuaded me to build one
2. this a project i had been aiming for a long time but will just do research and get all the help for now since this is a huge project
so now lets get going with the white pearl (i just love pirates of the Caribbean)
well i built it in 6 hours today and it worked. before going into the hibernation mode i had made a custom fighter jet style duct for one of my ducted fans (inspired by rcpowers) i decided that it had to be in this build and used this as the thrusters and used another 70mmfan for the lift power (its a monster
).
i was studying fluid dynamics while making this up trying to calculate the gauge pressure needed for the perfect cushion did some calc. too but then i took the tried and tested method of making it before i thought how it wiuld work. the availability of the custom duct just sped things a gazillion times.
DESIGN
the base was just a long full depron sheet and that was it.

1*11.1v 2600mah 30c lipo for lifter final version\
1*11.1v 1500mah 30c lipo for thruster (test this caused a problem as you shall see in the video)

MANEUVERING
i am working on the flexible turner mod on the custom duct (rcpowers inspiration here again)
more on this tomorrow
enjoy the video and pics (by the way i got a samsung wave 2 so the video and picture qualities are way better than my n72)
i really think that a cylindrical ducting would be better please suggest (VC bhaiya need your help)
well its a hovercraft and it works as one i think i should send it to you vc bhaiya for the detailing and beautification because i think it doesn't look as attractive as the white pearl should be dont you think
