Remote-Control Car Modifications

Hi, this is my first instructable so please be kind on the comments, any constructive criticism is very welcome!
When i saw the robot competition i was inspired and i decided to modify an old remote-controlled car i had, this instructable shows my process and what i added to the car.
Again this is my FIRST instructable :)

1- i flipped the car over in order to access the screws, which i then loosened using a very small screwdriver.
2- I then removed the car body from the chassis
3- Then i used red electrical tape to cover the car's body
4- I also made sure that i didn't cover up any holes
5- again using the small screwdriver i re-attached the car's body.

I used two small wooden sticks to make spikes to mount on the car.
1- Using a scalpel i sharpened the ends of the two sticks
2- I then used a red sharpie and some white insulation tape to add some colour to the sticks
3 - Then i used some "no nonsense" super-glue to mount the spikes to the roof
4- I then re-attached the car body to the chassis

This is the finished design.

Thank you for reading my instructable , as i have said this is my first one
so go easy on the comments :) , also it didn't take me very long (one evening)
more instructables soon!
please comment !!

I realized my RC car could be used to drop a firecracker, the two spikes on top are used as rails to hold the firecracker and then with a sharp brake the firecracker simply slides off, then explodes after the car has made a quick escape!
