I've often thought that preassembled/RTF helis should be labelled with a cautionary 'Preassembled for guidance purposes only ' :)

Originally posted by kenmalecki View PostHi all! New member here. I've been flying rc helis off and on for 10 years, so not a newbie. I have collective pitch helis up to 700 size - mostly Blade and Align. But I've been away from the hobby for a little while, so I'll have to be retrained :). I got the RotorScale B222 a few weeks ago and will start setting it up this weekend. I read this thread and fully agree about taking the mechanics out and rebuilding. I've been bitten by that before.
I have a few questions. Thanks in advance for any help you can provide!
- Should I use governor or throttle curves? Some esc's seem to work better one way or the other. I have mostly Kontronic esc's in my Align helis, and they work great with governor. What about the Hobbywing Platinum Pro 40A?
- What programmer works well with this esc? There seem to be several Hobbywing programmers available.
- What are the best settings for the esc?
- I bought the FC that Motion has in stock and has in the link on their B222 product page - Tarot ZYXS2. Is this a good FC for the B222?
- What are the best settings for the FC?
It will be great getting back into helis. I've always been attracted to scale helis, but never took the leap. After I get this beautiful B222 flying, I'll be opening up the Roban 800 size EC-135 that also jut got delivered. Yikes!
Thanks much!
Ken
As for the EC-135, I highly suggest looking at the thread over on ScaleRCHelis.com. There is lots of good info there on what's needed to get the fenestron dialed in and tail servo choice. Definitely worth the read before flying.

First note that the ESC that is supplied with the Rotorscale helis, is an older version of the HW 40A Platinum series (it is not the most recent V4). The manual currently on MotionRC's support page (Platinum25A40AV4.pdf) is actually the wrong one - it is for the V4. I located and downloaded the correct HW-40A manual (HW-01-PL.pdf) and have attached it to this post. Hopefully, one of the MRC guys will put this correct one on their support page.

In the meantime, I found the following videos to be both in-depth and very helpful. Although Part 4 covers setting up the earlier version of the ZYX hardware and software, I found that much of what he discusses applies to the ZYX-S2. His five part: "Flybarless Conversion" series covers a lot of ground on the proper setup of a 450 heli. Highly recommended! Here are links to all five parts:
HK-450GT Flybarless Conversion - pt 1 - Introduction
HK-450GT Flybarless Conversion - pt 2 - Building The RJX Clone Head
HK-450GT Flybarless Conversion - pt 3 - Installing The Servos FBL Rotor Head and Gyro
HK-450GT Flybarless Conversion - pt 4 - Radio and Software Setup
HK-450GT Flybarless Conversion - pt 5 - Final Setup
Hope this helps! :)Attached Files

But this is a pilot preference kind of thing, no?
I've found that a largish collective range is particularly handy when flying at low headspeed, where the blade needs more AOA to generate sufficient lift. Note that the airframe on these Rotorscale helis, (a Trex Sport V1 clone with a Tarot FBL head), allows for a rather large collective range (i.e. +/- 16°). Here are the ZYX-S2 travel limits I am currently using to achieve +/-12 on collective and +/- 10° cyclic:
Note that the rudder limits are for a non-stock KST DS215 servo with the servo linkage ball mounted at an 8mm radius from the center of the servo arm. These ZYX-S2 tail setup values will vary with other tail servo configurations. (The Tail LimitA and LimitB travel values are set as high as possible - just up to the point of almost binding.)

EDIT: MotionRC has updated their support page download to the correct manual version. :Cool:

Maidened my Rotorscale B222 Shadow Black Airwolf 450 today. Here are flights #1 and #3... (Disclaimer: kinda boring - wasn't pushing it, but I did go inverted a few times and did some highish speed passes.)
Have not hooked up the gear servo yet - thats next on the initial flights plan.
So far am liking these Rotorscale 450s from MotionRC! :)
I am also becoming more impressed with the el-cheapo Tarot ZYX-S2 FBL - seems to work just fine even in the undoubtedly high vibration environment of these scale jobs. :Cool:

Originally posted by ridgerunner View PostTo remove and install the fuselage, the right half of the tail mechanics (including the pulley and tailshaft) must first be removed. The belt is slack as fuse goes on and off. With the fuse off, the tail needs to be partially reassembled in order to set belt tension.

After around a year of flying my Airwolf, I started having issues with the belt constantly loosening. I tried a few things to stop it, including adding tape shims, which helped for a bit more, but was still temporary. I decided to switch out the mechanics for a Tarot 450 pro to get a TT tail, Upgraded to a HW V4 60A ESC, and also upgraded the tail servo to a BK3002. I put a few flights on it Friday in some gusty winds and tail hold was much improved. Will be nice to have it back as a regular weekend flier.

Regarding the Tarot 450 Pro frame - I assume the skids hole pattern differs from the stock Sport V1 frame. Just curious - How did you modify the fuse to mount the mechanics? New holes?

Morning all, how exciting, I’ve just got an email to say these are back in stock in the EU store (not sure they were ever in stock! not that it matters) so I’ve clicked the big buy it button and hopefully it’s on its way at last.
I’ve had a quick read through the posts but needless to say I’ll go through it in more detail once mine arrives and I start setting it up.
really looking forward to it and have always wanted a scale heli having only had pod boom styles before.
