Hi Rathikrishna,
That fireboat is absolutely brilliant. You have a great imagination. To use the available materials as you have and your skills with electronics is wonderful.
Just wish I had at least half your skills. And model making is the great leveller, doesn't matter if your male or female, just your imagination and skills to translate your ideas into your model count. Having lived in various counties, some where model boat building is virtually unheard of, and balsa not available, has lead me to now use materials I never even knew about when I was young and first starting out.
Well done, and wish you every success in whatever venture you undertake
cheers
