O.K same engine, prop and pipe.
What is faster, a quickie 500 type airframe or a diamond dust?
In other words what would be a more slippery airframe?

Just interested, as we have a plyon racing class that says as long as it has a front intake and side exhaust engine, you can race it. (most cheap 46 type engine, e.g OS 46 AX, Rossi 45) Which of these two engines would be faster with a standard 10x6 prop. Rossi would be fitted with an ENYA exhaust pipe.

Currently competing with a Sonic 500 ARF, but have a dust airframe in a box. Hmmmmmm

Two many variables

Got one of each--TT46 pro with mousse can mufflers--DD is faster

The Diamond Dust might be faster in a long, straight pass, but if you'll be turning around poles (which is what pylon racing is) you definitely want the Q500. There is no way that a Diamond Dust can match the Quickie's turning ability.

Dispite the delta airfoil losing speed in a turn I would put my money on the Dust. I have flown my Dust against several q-500 planes and it was no contest. Going around the poles at low altitude will require very small control throws and a good pilot.

The Rossi should be MUCH more powerful than the OS, not sure about the Enya pipe you mentioned (Quiet?)

I would say DD too... providing you don't yank it to death . With enough elevator throw you could loose like 50 mph in one 180° turn, but it doesn't have to be like that.

Also, with some extreme engine (not an FX obviously) a DD could become REALLY fast... I don't know how much faster a Q500 plane could go....

Let's say it's toss up...

Interesting to hear the result on this one...

We just had are need for speed this past weekend.The president of are club had a one way pass with a clipped wing Diamond Dust at 180mp,powered with a MVVS FAI 40.The second fastest Dust had a one way pass of a 165mph, with a K@B 40.The Q500's were averaging 135to 140mph, but their turning ability is awesome, they got faster with every turn.Unforunately this is a one year event due to noise restrictions, but what a blast to see these kind of speeds.Chris.

I'm just wondering how you're going to manage a pylon start with a Dust?

A Q-500 with a Nelson or Jett front intake side exhaust engine will be very hard to beat around the pylons. About the only other thing that can beat it is a QM40 ship. Pylon racing planes are a lot like Indycars in that they are designed with excellent turning capabilities. The Diamond Dust would be more like a top fuel dragster
