Transmitter weights
Core 2# 11oz
Spectrum 2# 8oz
Jeti 3#
the Jeti actually feels more heavy than the actual difference.
Screens - both Jeti and Core screens are great, Core takes the longest to boot up.
I had to change the mode on all three and they were all three very easy to change. No issues.
I did have to buy additional switches for the Jeti, the other two required no changes for my style.
