Wayne (or anyone with Wren turbines) are the Wren's that bad on glow plugs??? my current P-70 has 69 starts with 6 1/2hrs of run time and it's still got the original plug i installed when i get it new from JetCat.
Gee...I thought that was pretty good...my big block would only average 10 flights per plug. I'm using 20 year fox plugs that I got for free. I don't consider this to be any more than a trival issue.....
The MW-54 is a great little engine...it starts first time every single time, and, other than fuel, I have not spent a dime on it................of the 4 makes of turbines that I have flown, it has been the most trouble free and reliable.....
