RCU Forums - 2.4 Module and recievers for Futaba and JR

The Corona system cost me my Pizazz (which now cannot be replaced and flew on rails).

The first flight after system switch over went well with just some minor trims needed. The second flight started off like the aircraft had never flown before (well over 200 flights on it over many years) and like it was built so far out of "square" that no amount of help would save it. I did manage to get the needed altitude and re-trimmed the plane. While in the process of doing a moderate speed flyby it snap rolled without input and went nose first into the ground (fortunately soft enough so that the Irvine 53 was salvaged with no problems.

A full system checkout was performed on the battery, servos, and receiver/transmitter setup with no trouble noted at the time.

Fast forward 6 months ................. Completing a foamie F-22 I decided to install the Corona system in it. During system set-up sometimes the ESC would arm the motor and sometimes not. If the motor armed chances were high that another channel would be intermittent. I never knew what was going to activate when plugging in the battery to the ESC. After about 2 hours of dealing with the system I pulled it out, threw it in the trash, and put in a Futaba mid range 6 channel receiver.

Problem over................

Therefore I cannot and will not recommend the Corona 2.4 "systems" to anyone....................and I am a career reliability engineer in the avionics industry, so the proof still remains that you get what you pay for ..............IMHO
