Have been told by signatory engineer that drop tanks currently available for sale do not pass RMS departure angle rules.
I would be appreciative if anyone can point out to me a GMH document that offers a drop tank as an option on LX hatches.
If they were a factory option from the manufacturer, I may be in with a chance.
Unfortunately you are not the first person to be knocked back by an engineer on departure angle. There are plenty of Toranas on the road with tanks that do not comply however it seems that it is mainly engineers that enforce the rule. One option is to get the engineering done with a stock tank and then fit a drop tank later.

A few including myself have built tanks that comply with the departure angle rules but fuel capacity is limited to around 70 litres.
