I am looking at it strictly from an economic point of view. The new crop of cost effective competitive kits becoming available, it is silly and foolish to have to budget 50% or more into the initial cost a Vanquish (the Osiris is next, and I suspect others are on the drawing board) with no discernible performance benefit after you have spent the money, only so you can fly at the NATS once a year. That's why it is stupid. It serves no purpose other than raising costs. The 2 meter rule makes sense and has purpose. The noise rule helps move technology forward and eventually filters down to the masses and helps saves flying fields. Eliminate the weight rule for 2 years, keep the 2meter and noise rules in place and then evaluate. If after two years the argument holds true and $10,000 20 pound bi-planes become vogue and cannot be beat then its evaluation time again. So in summary you spend $650 on a Vanquish or an Osiris ($100 shipping) and then have to dole out another $400 or more to make weight defeats the purpose of the new market direction that manufactures are trying to create for us and is good for pattern. The new market opens up possibilities of new recruitment and keeps aging pattern flyers in the mix (critical for pattern). If guys want to spend $5000 on a pattern plane, then God bless ya, but a rule should not dictate a market movement and hold back new possibilities.
Probably the single biggest factor in cost are batteries for an electric airplane. To me, getting something that is not heavier than your car battery is a risk you take when you decide to fly electric. You receive little to no benefit flying electric in lower classes, IMO. This comes from my experience flying an OS 1.40 RX until I got to Masters, where I was a little too lazy to try and fly ahead of the pipe in some of the maneuvers, chiefly the Figure M.
Even if you spend more money to get lighter components to offset using lower quality batteries, or a heavier motor, you're still cheaper than buying a ZN Line kit, or even a PL Prod kit from 10 years ago.
Again, you know what you're getting into beforehand. You can pick up a cheap, good glow airplane (with a YS) and with a little bit of practice, go smoke everyone. It's all in how you choose to get there.
