Hi OZ,

I used to have the Cmpro Extra 300 S with the st 2300,the performace was just OK.The 330 L needs at least a 40 cm gasser according the manual.I"m using aFuji 50 El on this.Using of a glow engine in this size of airplanes is not economical at all.I can fly 32+ min. with my gasser on only 75 cm gas with a slightly rich high and low needle valve.And the gasser is simply more powerful with bigger props/in my case 21x10 Mejzlik/
