After flying a FG-11 Saito 4stroke Gas, I may reconsider the use of the DLE 20 now. The DLE is a bugger to get dialed in some days, you think its tuned well, fly it for a day, then a week later, its running like crap. The Saito, I have not touched it since the first flight, and I have over a dozen on it now since I got it last month. Makes me want to swap the 20 off the 4* with the FG-21 now.
