MJD, Lots of stuff to respond to here, but then I know I owe you another as well
The Team Race Diesel - they use smaller ventruis to minimize the fuel burn. I had a few of the Fora junior/pioneers which had a 3.4mm venturi spinning a 7x6 around mid 15's after I drilled one out with a #1 drill bit it would do 16,900 on the same prop.
On the photos, I have always left my camera on max resolution and they would load up small and normal, so I think something was off on the RCU software when I loaded these two.
