I am in the process of choosing an engine for a 40 size Dago Red. I am leaning towards the 60 size engines.

Does anyone have experience on this size for pylon racing?
Which engine/prop combination would produce the top performance (Glow)?

If this is a fiberglass Q-40 model, it will fly the fastest with a Nelson or Jett Q-40 engine. A used short stroke Q-40 engine should bring the speed up to 170 to 190 mph. Most of the racers are now using long stroke Q-40 engines. This combination will go even faster but is costly.

If you still want to fly fast but don't want to spend much money, try a Thunder Tiger Pro 40 with a 9" x 6" (or 9" x 7") propeller. This combination should get you in the 125 to 140 mph range.

I've attached a picture of my Stinger that was powered by a Thunder Tiger Pro 40.

Do you have a link for the q-40 engine, since I cannot find it on their site!
I was thinking of OS 95AX, since it is the only one I can buy locally and have easily available spare parts with a marcs muffler. Maybe with a 11x10-11x11?
What is your opinion on this?

Anthony,

You need to post more information on what Dago 40 kit you are talking about. Is this a sport plane you bought from Tower Hobbies or similar place? Or are you speaking about a Lyle Larson Quater 40 Dago Red Pylon racer?

These planes are very different. You could NOT put a OS 95AX engine in a Quarter 40 Pylon plane....you would never get the CG to work.

I have had 3 World Model Dago Red 46 sizes and I can say dont mess with two strokes if you are going to race. Either put a YS110 or the new YS115 in it or go electric. A two stroke will yield good speeds but a four stroke will do even better. On the YS110 use a 13x13N APC or on the 115 use a 14x14N
