Tower Hobby / ST Model / Sheng Teng - Arcus M - RMS Setup This video is in response to a series of questions from Grant Louis. Hopefully this helps! Enjoy, Like, and Subscribe! Thanks for watching!
Hey Brian.. just reporting in.. had some good flights yesterday and today.. Very balance dependent... Thank You for all your help and for stepping up..
Hi Brian.. Well, I'm all setup per your instructions.. The only thing I changed was in the throttle curve.. 0% 0% 20% 48% 100% That way it gave me a little extra space for using the rudder without worry of just nugging the throttle while thermaling. Thank You again.. Grant
If you wanted to try it, you could set the Rudder Expo to less than 0%, like -15% and you'll have more sensitivity to the rudder, thus less likely to move throttle forward. Wither way, I'm really glad to hear you got her setup. It was a pain in the butt to figure out, so at least now we can call it 1/2 a pain in the butt since at least two of us got some use out of it - LOL!
Hey Brian... Update... My crappy rudder servo failed so I have 2 metal geared servo's on order... On another point.. I didn't like how stiff the elev linkage worked so I dripped silicon spray down the linkage tube from the elevator end... works much smoother now... Just FYI..
Hi Brian... I have a LemonRX Plus also... I like your idea of putting the antenna's in a straw for security and placement.. Can the ends be in the straw also..? The whole antenna? Thanks Grant
Grant Louis I recomend the drinking straw, but my first attemp may have caused this plane to fly litterally into a tree! That was using a gas tube from a lighter, which was a great fit, but must have caused way too much siginal loss. Yes, you can plut the clear portion into the dringing straw, so long as you dont have carbon fiber dringing straws - LOL Also, one thing with a tight fitting setup, such as this or many other gliders, definitely a good idea to range test the plane before you try and fly the thing... Thanks for the question
Please help me, Brian.. I got this model as a gift recently. It was laying around about 2 years in an aircraft hangar, and it looked actually good for that. I am using a FS-i6 transmitter. When I advance the throttle on this baby, the motor can not extend itself. The servo (?) to lift it does _something_ , but nothing happens, the motor is not coming out. There is a weird humming / spinning noise and heavy vibration, also very loud. The motor itself (to spin the prop) works. The system also retracts itself but once it is back in I cant throttle up again without physically touching it. Any suggestions, what might be the issue? :( The previous owner said that I need throttle callibration... ? Please help. Its such a beauty. Sorry for wrong gammar or spelling, greetings from Germany :)
This plane has LOADS of issues with the RMS (Retractible Motor Assembly). It's all based on an el-cheapo servo sequencer, and once you get that thing dialed in, then you only need to worry about the mechanism that prevents the prop from spinning, and returns it to its home position. If I recall, you can simply separate the Motor and RMS Servo, and eliminate this sequencer...BUT then you have to waste a channel on your radio system :( AND you may want to setup a sequencer on your transmitter, if it's equipped to do so. I had to replace my Arcus, since my RMS Servo was DOA (well, died after operating about 2-3 times, or some such thing)...Tower Hobbies replaced the fuselage after I realized you basically have to RIP the plane in half to get that servo out. NOT a serviceable part, if you ask me!!! Start here, and do this FIRST... Separate the two controls. MOTOR on Throttle Channel (SET UP A THROTTLE CUT TO SAVE YOUR FINGERS!!!) RMS Servo on an Auxiliary Switch....doesn't matter which one. Once you have the sequencer out of the picture, extend the RMS....YES, you WILL need to fiddle with the "end stops", meaning you'll have to change the servo setup, particularly the percentages above and below 0 (center) to get that thing to land in home position. Also keep in mind, there IS a break on the RMS arm that stops your spinning prop, before it enters a "locked" position, but this is the fatal flaw of the mechanism, as it will fail after about 10 flights, even if you get everything else setup. This is where you would like to setup SOFT breaking on your ESC. If you do HARD breaking, the prop will stop out of HOME position, and will KILL Your RMS servo on the first flight! Soft breaking will allow the prop to come back into the home position, without killing the latch that the prop strikes as it retracts into it's home position. I know this is a lot, but you kinda have to play with it (A LOT!) and I'd encourage you to make sure you're 100% comfortable with it before you think about launching it. This plane will make you feel good, then you'll get up in the air, with all the different aerodynamic forces involved, and she'll work like 60% of the time...even though you'll bench test perfectly about 99% of the time. It's a ball of frustration, this plane, but you CAN make her to fly. I still have mine in my basement, but if I recall, the RMS is kinda broken, to one extent or another. She doesn't get flown also, because the wings are soooooooo flimsy. I covered them with tape, which helped, then later, I tried an epoxy (pretend fiberglass job...that sucked) and made her fly more like a brick LOL
@@BrianPhillipsRC Thank you so much, Brian! That was one hell of a quick reply. I guess the conclusion is that the servo is dead. (I am somewhere calm now that I didn't break it. xD ) Throttle cut is only for own safety, right? Because I don't have it on my TX... Thank you a lot ! :DD
Hi Brian... had my fist flight today and it didn't go to bad except I kept bringing up the motor pod while using the rudder.. I have the same setup as you gave me but I tried doing a mix that when I have the Thr Cut off ON, Aux1 (RMS) doesn't come up... Is that something that can be mixed? If so, how?
Grant Louis So your setup stops the RMS Boom from coming up when your throttle cut is ON. Might be a difference with your DX9....maybe Gen2 throttle cut is handeled differently than on my DX18 Gen1. I guess, you could just try and mimic the setup of the RMS (AUX1) mix to the Throttle stick, but not sure if it'll work.
No.. Sorry.. didn't make my situation clear.. My setup is just like your's.. Followed it to the T.. :) what I'd like to do is stop the RMS boom from coming up when the throttle cut is ON... When the Throttle cut is ON. it disables the boom from coming up.. What additional mix could be created to accomplish this? Thanks
Grant Louis Oh, that's faily easy. Where you made you mix for Aux 1 to Throttle, simply assign, instead of "ON" set the Throttle Cut Switch you picked to allow the mix to be active when in the Throttle Cut OFF position.
I'm uploading the video to show you how to do this now... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7DjAHjl1M64.html ...it'll be published in an hour or a little longer. It was an easy solution, but hard to put into text
