I was getting new DVII carbs for like $10. That makes the $50 engine $60 but it then will run like a much more expensive one. Sure the Thunder Tiger is a great engine and I love the heck out of all mine but I am also the biggest cheapskate in the world. Sure its still only a few bucks more to get a really nice engine right out of the box( I have great luck with the TT GP42) but if those cheap engines ever go on clearance?
And no if I was to build a really nice 3D plane or really cared about my airframe I would go with the "good stuff" but, especially for a trainer that is probably going to get kinda beat up, I would use a decent "el cheapo" IF it would throttle properly.
That way I wouldnt cry as hard when it took a dirtnap.
I trained on a PT-40 with an Aviastar 53 with a DVII carb, it throttled well and made great power. But I am now using my trainer airframe to test different engines , currently it has an Irvine .40 with a GMS47 muffler and that engine will spoil you!!
Which one should I test next week?
Where are you getting TT Pros for $80?????? They are about $100 at Tower plus shipping.
