"yes i have seen these thrusters.. but i have to use same motors for both air and underwater operations.."

"you are right..but i think same propellers will do the work..  still i am finding ideal propellers which could work more efficiently.."

"thanks for your advice.. but i still confused whether to waterproof the motors or not ?.. and if i should which kind of sealing i should do? mechanical or oil filled?.. today i met a guy.. who can help me to build these things (since i don't have…"

"yes.. i have seen this part.. i am using same method as you said.. it will be neutrally buoyant and.. and propellers will turn 90 degrees.. now i have to work on its buoyancy factor.. i have to build it by myself i think.. because the ballast tanks…"

"i think these might be the advantages
1. Its a hybrid which will do both the workings of quadcopter  and a submersibles.
2. we can reach distant place more faster through air than in water.. once we have reached the distance we can dive into the…"

"can we use same propellers which we use in air?? doesn't it have any negative effect? i mean torque required and also the load on the motors?
 "

"Wow.. lot of things you have been discussed.. which indicates that its almost impossible to have underwater wireless live video transmission using present technology.. i think then i have to go with your favorite idea.. which is i think more than…"

"i know many information are there in google..since i am new to this i am confused about things which i should do and things which i shouldn't.. on that i have project budget.. for which i have get best things at less price.. if you could help me it…"

"and i just got it confirmed that i have reach max of 30 m depth.. "

"i got it from this journal (which i have attached to this post) .. if its not possible then which wireless communication system i can use? ROV TR.pdf"

"Feeling very happy by seeing this post.. i was working on this from past  4 to 5 months.. and it would be my final year engineering project if i am able to submit its synopsis and possible cost report within 15 days.. i am currently working on its…"
