micro rc airplane

Hi! I'm making a list with all the necessary compontents to make the full model, but I have a question
about the microchips.
In the schemes, there is the "base" code of the chip but, when I search for them in shps there is only variations, so, what microchips I have to buy?

Example:
in sheme-PIC16F630
in shop-PIC16F630-I/P; PIC16F630-I/SL; PIC16F630-I/ST

PD; Sergey, I've decided to make the 4ch transmitter

Regaaaaaaaaaaards

Hi! PIC16F630-I/ST, but it is best to PIC16F630 TSSOP-14 package as it is the smallest.
I will wait from you the news.

Hi! Ok, thanks for information.
So, what i have to consider when i buy the microchips????
An other thing, have you the technical information of the motor? I want to know if it will have the necessary power to makes move a 1/72 spitfire MK V, it's about 13 cm length.

PD: MERRY CHRISTMAS!!!!!!!!!!

By purchasing chips you should pay attention to their size - the smaller the better.
The smallest chip is PIC16F630 in TSSOP-14 package.
The motor, as in section of the site "assembly", has thrust 0.5-0.7 grams, at a current of 100 mA (30000-40000 rpm). The weight of motor with a prop is 0.16 grams . If you add to this motor gearbox and a larger prop, you can get thrust 2 grams or more.
Thank you for your congratulations. You, too, with Christmas!

Hi! Thanks again.
Ok, i have another question. Sorry, but i'm very boring, because i want to ask you again for 4ch receiver...but i want to exploit at maximum the 4ch transmitter.
I have some ideas, but i don't know if they're corret, so, if you can, tell me what do you think:

The PIC16F630 has 14 pines,( the receiver pic), so, can I use a pic with 18 or 20 pines to add another channel?
Or, can I add smaller pines to have more channels (1ch by smaller pin)
Or, can I make two same receivers and programme one to use motor and elevator, and programme the other to use coil and flaps, for example????

Thanks for you big patient with me

Simply adding another chip not solve the problem. Free pins of the chip is there, but everything to work without the programmer can not do.
We must look for the receiver circuit with 4 channels
