thank you sir...but here i do not have any option..i am living in a remote village,in KERALA STATE, INDIA.here we cant buy any needed materials easily..yes i can..only when i am in duty.when i am in duty, i do not have any enough time..so i will do all my works when i am in home...i am doing all things from, handy materials, not because of the lack of materials...i born in a very rich family, by wealth and tradition.our family is a farmer community, situated near a river in kerala state.so i have ample of water sources around me...i was making models from from the age of 6.i got my first futaba ATTACK 2 radio system, when i was 8.my PAPPA gave me it when he goes for research in london.within a year i got the second one.it was a bionic gold from futaba.up to these days both are un used by me, because both are precious treassure to me...then i got thirdth one, from my friend, its a SKYPORT, YFM 4 from futaba.now i have two of them, using now.i brought home one more system, when i was returning home, after my research in aeronautis, is a DUPLEX from germany...i have ample of motors, are brushed and brushless...i am also making flying models ...fighter planes...we also have a supply of balsa wood here in Bangalore.but still i am doing all models from, thermocol,paper, and thrown scraps..why..?yes..at the age of 12 i compleated more than 200+ models, all from kits, all from, italeri, airfix, hasegawa, academy, minicrafts, zwesda,and many...once my uncle came home and made fun on me...he told me, RACHU..you must make models of your own...making from a kit is not much creative...so you must find some materials and make your own models...it was an inspiration to me....after that i have compleated more than 300 + models only in water based crafts...i know, now i can make a 1.5 metre long,war ship, all with home made R/C, within a month, and for around 6 dollars...if i go for a conventional root, it will costs more than 2000 times of this money...i always wander along scrapyards, to collect motors and Tx Rx ICs from scraped old toys...and i am a gold medal winner in model making segment in my own job.so i am here to share my knowledge to all others, while have to take knowledge from all others...i hope, making a model from blank working table, to an entire working model,by all means is more satisfying ....making gearboxes..making servos...radios...wow..its nice...thanks for the instructions from you,and i am here to hear all from you...with respect..Rathi
