Temps have dropped here and i`m still running my reed stuffed dle30s. The metal based epoxy i used is still unchanged,just as the samples i immersed in fuel for 6 weeks remained perfect.
They take about 15seconds more warm up and run great from 1850 to 9000rpm on the ground. One can only guess what it does unloaded in the air. What i will say is at level WOT i can go to idle and pull a large round loop with the model whistling as it levels out 18x8apc.
One of the motors has had some internal work done now to the cylinder and the piston. The ports have been changed to allow more and adjusted flow direction and the piston has had similar with a hole also added for the boost port. It is a very strong runnig motor and burbles a bit at very low throttle.
