So now you need to rename this thread to "Converting a low cost Chinese r/c car into an r/c boat"..

You are getting there....

Happy boating

well how can i change it?
anywys what about airboat?how caan we make it?

You can call me on 9833607902. Will help you with this

hi ankur,
 actually what u r thinking is not possible at all bcoz the chinese car works on radio which is having IC called TX-2 and in Rx the IC RX-2 ,these ic's are specifically designed for operating with radio controlled short range cars and these IC's are not capable of controlling servo bcoz servo works on input signal which is PWM(pulse width modulation),and these ic's drive H-bridge which are used to control DC motor supply polarity depending upon the input ,where H-bridge will have a 2 inputs accordingly it will change the direction of rotation of motor clockwise or anticlockwise ! and these ic have 5 controls like Forward ,backward,right ,left and turbo , another thing is u can configure to work on twin engine aircraft where it will have no servo but controlled by thrust vectoring with twin engine like add power to engine climbs and reduce power it descends and vary speed btween engine it will turn accordingly.
if have doubt pls go to www.datasheet4u.com type TX-2 u will get its datasheet! if any further doubts pls let me know.

well ok i now don't just want to play with the tx/rx bet will simply make a another car out of it

Looking at u r age and the question u r raising are well advance than other kids in u r class.
Good Keep it up [reminds me of u r age].

Secondly if u have desires to experiment on electronics then Go ahead,
take some adult suprevision while experimenting around u.

But if u intend to fly, then seriously dont get into electronics component level at this moment.
knowing basics electonics is more than enough for flying.
concentrate on aerodynamics rather than electroncis, aerodynamics will be more usefull for u r experiment.

Google for micro Vapor plane, this may add some reference where to begin with.

I think its best to buy those 2700 worth 2.4 Ghz  Radio offered by Mr Sai (rcforallin). Nothing can beat that... you don't even get a 2.4 Ghz receiver at that price. This is all if you want to stay in the hobby and just not like paying a short visit as one used to do in vacation to their Granna's house!

One thing more, you would also need the radio to be 'Proportional' -Even the 2400 Cheapo RC plane I bough didn't had a proportional system for twin motors and if you pull the stick left/right, on of the motors used to just STOP!!

Start well so that you don't face frustration in the beginning itself.. keep energy for fruitful challenges

i added this in another thread.anyways i think this link would be of help to the topic creator.!
