RE: Is this a big enough cooling hole?
yes, all went brilliantly.Apart from the exaust cept comming loose cos i couldent get the nyelock nut onto the exauset bolt so i had to use a standar one which kept on falling off making the exaust come loose and loosing most power, not brilliant in the hover, this eventually lead to a crash, minor but irrotating. Got some good video but my stupid sony ccd-trv27e video com wont let me upload ont my computer[:@]
