Well, if you already have the DLE50... :-)


Here is a review from Dynaflite's site
http://www.dynaflite.com/reviews/gpma0510-rce.html

"Dynaflite recommends engines sizes from 1.08 to 1.80 2-stroke, 1.20 to 1.60 4-stroke, and 1.5 to 2.1 gas. The instructions provide firewall details to install an O.S. 1.20 and the U.S. Engines 25 cc power plants. Installation of servos, battery, etc. is designed mid-way back in the fuselage tail section to offset the weight of the larger engines."


so your 120AX is right in the middle of the range of glow engines. The largest gas engine they recommend is 35cc ( 2.1ci ). I think the 120AX wouldn't be a bad choice, though it probably wouldn't give you unlimited vertical. It all depends on what you want....
