Official RotorScale MD500E Police Blue 450 Size Helicopter Discussion Thread

[Larry D]

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.

[Gravythe clown]

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.

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.

[Larry D]

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 have the Huey450 and the blade grip on one side had a lot of play. I tried removing the screws to disassemble, re-grease, and re-tighten. But, those screws wouldn't budge and I stripped them out. I have a replacement head coming, but I have a feeling the blade grip play was causing my huey to "wobble."

[Gravythe clown]

Have you checked the tracking. Tracking can make a big difference especially if tuning a multi-blade setup.
also check and make sure your phasing is correct.

Just wondering guys...have any of you experienced a main rotor "wobble"? This is not toilet bowl, but it seems the main rotor wobbles. That's about the best way I can explain it. It seems to happen at higher RPM. It doesn't seem that the Micobeast is making the adjustments, but I may be wrong about that. The "wobble" makes hovering extremely difficult and any sort of circuit flight unpredictable. (1) Never been crashed or even had a hard landing. (2) I have made sure the swash is level. (3) Made sure the blades are balanced and the CG on both match perfectly. Each blade is exactly 22g. (4) I also balanced everything with the complete rotor head and blades on a DuBro balancer and everything checks perfect. (5) I inspected each blade - literally with a 25 power magnifier and can find nothing. (6) Checked and re-checked to ensure the main blades were not too tight (wish I could find a mini torque wrench - maybe someday). The only thing I can think of is a slightly bent shaft that is so small that it doesn't show up when balancing. I have not changed the main bearing (yet), because I don't have one (yet). ANY ideas??????

Mine sits into a hole in the boom as a stop.

Thanks....That's what I thought it should be. The one I have does not. Two new ones are on order (sigh). Was out at the local club field the other day and one of the members commented that RC doesn't always mean radio control...in MY case it means Repair Constantly :)

ALSO - If anyone is using a Futaba radio I would love to know your settings to fly this bird. Almost everyone I have talked to uses Spectrum and of course the settings in a Spectrum radio and a Futaba radio are different. Its driving me CRAZY!!! Well more crazy :)

[Larry D]

Tail rotor assembly question guys - Have any of you taken the tail rotor assembly off yet? My question regards the metal vertical stabilizer mount. This small aluminum piece of course not only mounts the vertical stabilizer, but also appears to have a "stop" to keep the whole tail assembly from rotating on the boom. My question is...if you have looked at this...does the center solid metal pin actually fit inside the hole in the boom or does it fit flush and not actually touch the boom? I can't figure out why my tail rotor assembly wants to shift slightly. It seems reasonable to me that it would actually fit into the hole in the boom. Mine doesn't and I am wondering if I have (another) broken piece. Any thoughts?

MotionRC reaches out to me Friday. They offered A fair resolution to my issue. I am annoyed it had to go to that level and voiced my concerns on the situation. I’m positive they understand my concerns. It a not a money issue as it was a moral issue. One I never thought I would have had with MotionRC since they always seamed you be one of the best.

i will accept their offer and move on. I will continue to do business with them and see what the future brings.

companies are only as good as how they handle their worst situation. The fact they want to do the right things speaks the right message.

Glad to hear that issue was resolved and glad to know you will be sticking around on the forum. Got the 5 blade head in and as soon as the blades get here I will be making that change out.

Guys if you have any questions on my MD500e set up in the future, you'll have to ask me on RCG. Motion did me dirty over $40-$50 on my UH-1 purchase. I will no longer purchase from them or promote them. Just glad it wasn't a high dollar lesson. today will be my last day here. Good luck on your mods and fly safe.

Gravy

Sorry to hear that man. Would love to stay in touch.

Thanks for the advice on belt tension. I found the screws had not been tightened and the belt was slipping. Not a lot of fun, but I learn something new each time. Expecting the five blade rotor head in today or tomorrow and while I have all of the mechanics out, it will be a good time to work on that project. BTW - the change out to the Microbeast from the Tarot worked out great, boots correctly every time now. Thanks guys!

[headshot001]

Does Align have something like Blade in reference to stabilization? Thanks

[Gravythe clown]

For a first heli I would not recommend something with a scale fuselage. Get a 300 or 400 size something like blade or align and learn to fly that first. No reasone to tear a clean body up while leading.

gravy

[headshot001]

I notice parts are not available, seems that is an issue? Would this be a good first heli with an instructor?

thanks

[Gravythe clown]

Unfortunately I haven’t found any other way. The only way I know of it to loosen the boom at the frame and pull it out and then tighten it again when tight enough.
