| Latest update and conclusionHi all,
I purchased a RJX50 recently and transferred the Futaba receiver, Spartan gyro, GV1 and installed new Futaba BLS352 servos for cyclic/ BLS251 for tail. Because I am still using a old trusted nicad 2400, I realised I was drawing something like 500mah for each flight and I could only gain about 1000mah from the nicad batt before I decided the voltage is too low for me risking a third flight. This led me to purchase a SGP Reactor thinking that their separate bus powering the servos might work out for me this time.
I WAS WRONG. First flight with the SGP reactor I simply hovered around and nothing amiss happened. Second flight I experimented with Tic Toc (2 or 3 only) to see if I felt anything amiss. All ok. I proceeded to fly a fig 8, opening up the circuit going faster and faster each time, and I felt my elevator giving me delay response (esp in turns) and before I could decide to land the heli to avoid crashing, the darn thing lock out on me again. Exact same spot, same turn, no elevator, no nothing, did not go into failsafe too.
Now, I went through Align 6amp, Arizona Fromeco and now Scott Gray Reactor. It has to be my heli or the receiver but this is now a completely new heli and even servos.
Not wanting to jump to conclusion, and seeing my field mates using Reactor and Arizona on 50 and 90 sized helis with no issues, I decided to bite the bullet and just buy a whole new TX system jumping onto the 2.4 bandawagon. I ordered a JR 9303 with R921, set the whole heli up, left the Reactor in there and pray real hard before I flew at the field.
4 flights thus far, no issue. Damn, I wished I could have done the upgrade earlier. I was just being stubborn refusing to believe the receiver had issues with regulator, since it does work 100% fine with Nicad, why the hiccups with regulator (linear and still yet affected by noise maybe?) and yet pass range check with flying colours? I will never know I supposed.
Anyhow, I think I owe Arizona and Align a big apology, my bad about concluding the regulators are not up to task. Now it is not a case of faulty receiver or whatever, I sent them (2 of them)in for checks and both are fine. They just won't work with regulators for some strange reasons, 29mhz 149DP dual conversion. It is just strange that they will work in planes with BECs like Castle Creation, Medusa etc and not in helis with regulators. I am not going to point fingers, but wanted to post this so that all can know what solved my problem at the very least. Futaba folks did tell me that they can't support me if I use third party stuff with their receivers when I asked about regulator compatibility. Oh well, I decided to change more of my stuff to third party ones lol, solved the issue and that will count for me as a big step forward. I think I can sleep better already. |
