Ed, that makes good sense as the RCEXL unit requires no min RPM to fire. I'm sure Matt will let us know what the end fix is.
Matt. I'm quite interested in your DLE 55 setup. What header did you use and what was the length that worked the best? Pretty sure this is the setup I will go with.
The header was a stock return to center from DA. At least I think it is stock....it has a flex joint at the goose neck wrapped with teflon unsintered tape. The pipe is the stock ESC G55 carbon unit. I'm using a length of 28" from exhaust port flange, around the goose neck to the baffle. The length is not terribly critical at +/- 1". Output won't change unless you went way out on the length
The soft mount is my own; similar to the Hyde. I'm sure Merle will build one for you (200+ $) or I can help you through a build if you are so inclined. I have a thread somewhere in these pages on the building of a stand off type of mount. That thread was written around a ZDZ40 engine but the techniques are the same. My mount has an OD of 5 1/8" and is 15/16" thick (not terribly critical, you can make it +/- 1/8" and it will work well). Weighs just over 4 ozs.
I admit I was skeptical at first because the power output on pipe was terrific, but now after 60 flights give or take (about 4-5 gallons avgas) I no longer am. Prop was the Mezjlik 20x12. I broke the prop on it's last flight and am in process of casting a mold from it
