After hearing that review, I think I'll stay with the H9 Hellcat. What engine I should get for the Hellcat? I've heard great things about the Saito 100, and the YS 110FZ sounds nice also. The other option is the new Zen 20cc if it fits. I'm not sure about paying out $339 for 20cc though. The H9 Hellcat manual does not have the Zen 20cc in the recomended engines section. That's strange as its fits in the H9 F4U and P47 60's. Has anyone flown the H9 Hellcat yet, and what engine are they using? I sent an email to Horizon today asking if they have beefed up the weak retracts that were used in the H9 F4U. Haven't heard back from them yet. I have a brand new pair of 3/8" robostruts that I was going to use on my top flite 60 Spitfire kit that I'm building. Would those work with the Hellcat's retracts?

Thanks
