Yes, Bruce nailed it. This is exactly the pipe I was referring to & as I said it is fairly inexpensive at $14.99 & the .46FXI really does like this pipe, of course you'll need to remove the tuning limiter from the carb if you haven't allready done that. I think you're making a wise decision & you can still get your new Pulse & take your time to assemble it as perfectly true & staight as you can, as you will be in no hurry to fly it. Then it will be ready to go when you're ready to fly it. I've done this with a few planes, the key is finding the patience once it's built not to fly it until your truely ready. Been there, crashed that![:@] Good luck brother, have fun!!
