Thanks guys. I went over everything again and paid special attention to blade grip and tracking (everything looked really good) as well as phasing. Thanks Gravy and CM. Then it dawned on me. What if my cyclic gain was too high for my current setup? Sure enough, I went back and re-read the gyro setup. I had NOT re-adjusted the pod for the cyclic. The instructions caution that too high of a gain on the cyclic will cause the type of "wobble" (they correctly call it oscillation) I am experiencing, just like a tail that is "wobbling" and not holding heading is likely caused by too much/too little gyro gain thereby causing oscillation. The instructions PLAINLY state that especially in 450 size and smaller helis this is not uncommon. Then I had an unpleasant memory flashback to school days long, long ago and a professor reminding me to RTDB (read the damn book). Yet another senior DUH moment :). I had no time to do a flight test last evening and test this. Keeping my fingers crossed that it is a simple fix.

I couldn't wait. Beautiful no wind morning. Lowerd the cyclic gain from 100% (it is a 50 to 150 scale) to about 70% and what a difference. No more/very little wobble/oscillation. A few more minor tweaks and I think it will be rock solid. Lesson learned - RTDB!!! Thanks again for the help gentlemen. All good reminders that when you have checked everything, check it again.

Holy cow you had you cycle Maxed out? That will do it definitely. I’m using the microbeast plus. And all the of my cycle gain, cycle feed and tail gyro response are all right around the 50% mark got my 450 size helis. On my Huey my tail gyro response is like 60%.
glad to here you got her sorted out.

It wasn't "maxed" but it was midway on the scale of 50-150. Effectively default (100). LOL - Yeah that'll do it on a 450! Also running the Microbeast Plus (v5). I think I am going to drop it a bit more and see if I get exactly what I want. Kickin' my butt for not even thinking of that to begin with.

Talked with Ed at MRC today and after going through several checks and diagnostics it seems the Tarot ZYX is hit and miss (sometimes it would boot correctly - other times not). Not going to risk it and will be switching to a Microbeast. Fingers crossed. Thanks for the help guys. It was a frustrating time when I KNEW my connections were all correct. This is my first scale heli. Flown a number of booms in the past and looking forward to seeing this one fly and working on the total scale look and feel.

This is ridiculous to even ask, but I need to. Has anyone had issues with inserting the skids of the MD500E Rotorscale 450 into the legs. Mine just will not go. The legs almost appear backwards with the longer at the back sticking out and the angle to push the skid through the hole in the back leg just will not go.

Moving up to Scale Helicopters from a 200 size. Thought the Rotorscale MD 500 would be a great place to start. I've been looking at it for the last 6 months or so while I became proficient with the OMP 200. Thankfully I have a buddy to help guide me through all the steps. Mine arrived yesterday and what beautiful model! I will be updating my progress.

I put my MD500 together and got all the settings in on the TX, ESC and Demon 3x. Tried to get a madani flight on it, but when I spool it up the tail begins to spin when I reach the upper third of the throttle. It also seems like I’m getting interference on the servos cuz the seem to jitter every once in a while without any input from the radio. Any suggestions?

Yup, did that from the get go and I’m glad I did. Turns out I didn’t reverse the tail rotor servo direction. Had to make several adjustments and on the last adjustment I forgot to reverse the travel. It’s working better now, but still get some occasional servo jitter, which throws things out of wack when I try to get it to hover. Thanks for the help. I appreciate it!

I wanted to position it to the rear on one of the trays, but there isn’t a whole lotta room back there. That’s why I chose the front tray. I’ll make it work!
