Hey Guys, quick question.

Flew my Kougar today on a os 46ax and tuned pipe. First flight for this combo after some checking/cutting and fiddling on the ground. Anyways at one point I throttled back from WOT and it took a LONG time to come off WOT. Fearing my RX Pack was low <slow servo> I landed the model.

I could not recreate the problem when I taxied back to the pits. Throttle response was good, and it came right down then closing the throttle.

A flyer made the comment when a 2S is on a tuned pipe sometimes that happens. Ok... I thought to myself, how in the world does the engine maintain WOT if I mechanically close the barrel? It's got to pull air <and a lot of it at WOT I presume> from somewhere so how in the world does the addition of a tuned pipe affect that?

Ideas??
