Recently picked up a protozoic and orphaned RV-7 Empennage kit #70101 off eBay.
Subtract out the prototype RV-7 and yes, as confirmed by Vans, I’m the proud owner of the 100th RV-7 kit!
Not sure yet if I’ve gotten myself in over my head, but I’m going to make a go of it. I kind of have to at this point.
#100 has already spent over decade forlorn in a basement! (No fault to the original builder….. They have valid reasons.)
The packing list shows that this kit was shipped with the pre-SB 02-6-1 RV-7/8 rudder.
I’ve searched the forms for all the info available and it looks like the two driving factors for going with, or not going with, the RV-7/9 rudder upgrade are…
1)Better spin recovery as noted in the SB 02-6-1.
2)Negative effects of the larger 7/9 rudder on W&B/C.G..
The big questions at hand are…….
1) Is it worth it to acquire and build the larger rudder?
2)Does Vans still honor the complementary rudder upgrade as noted in SB 02-6-1?
