I received some good advice from members here on this thread about this debate, thank you.. But now I have another spanner to throw into the works on this subject whilst attending AirVenture last week, I was informed that RAA don't require a bi annual aircraft ( Microlight ) Rego inspection , unlike the HGFA.. So this , if is the case, will also effect the bottom line of who is the more economical choice, eg the fee charged for an inspection every second year must be taken into account,even if HGFA rego cost is more attractive than the dearer RAA Rego, factor in this cost (?) what ever it is , it will likely raise the $22 a year advantage the HGFA seem to have up more inline with the $160 a year Rego RAA charge. Let alone the added travel costs Bienially. Then that just leaves the difference in Membership right ? Dissapointing news for me, as the figures originally had me leaning in favour of keeping the Trike with HGFA
