The picture of how light sport aircraft reduce the cost of flying is coming into view. I just purchased brake fluid for the AOPA Remos (it’s OURS until you cruelly win it away from us) from Walmart for $2.67. It takes DOT4, auto brake fluid. You’re not even allowed to use aircraft brake fluid. You can do a lot of maintenance on the aircraft yourself with factory training. The sport pilot rating, if you choose to go that way, knocks a minimum of $2,500 off the cost of becoming a pilot compared to the private pilot certificate.
UPDATE: Looks like we will be switching to Aeroshell Sport Plus 4 on the next oil change.
