I have one pending project.....  I got one radio control kit and servos and also 2.5cc petrol engine(glow plug engine) + transmitter and receiver..... I got it from Conrad Germany and few stuff from France quite long ago. I guess my collection(kit+parts) is complete... because I had shown it to expert at France and he told me to buy missing stuff ..... which was one extra servo and starter battery spark plug etc... 
my problem is Manual is in German, it is quit time consuming to scan ocr and translate it.... and manual is only for kit......not for the other parts like engine trans-receiver which was purchased separately.  I  am aware of mechanical system but not very much familer with their interface with electronics.. and any mistake....is there any place i can get overall idea of electronics and mechanical system and their interface?Any idea of Fuel ? is it normal or special because I know diesel engine has special mixture ratio... and we had suffered to source ether Any source in Gujarat/Maharashtra .... will do...at least some source to buy balsa and other stuff.....
