Originally posted by bpjacobsen View PostBeen flying my AS350 since yesterday and really enjoying it. It so cool looking up in the air. Even did some inverted, though I don't plan to do much more than scale/sport flying. Afterall it's a scale model, no point in beating it to death and risking a catastrophic crash. Anyway, I was wondering if this heli would work with a 1550 5s battery or an 1800 mah 6s? The listing on M r/c says 4s but the begininng of this thread says 6s. Is the motor and esc capable of handling 5 and 6s? right now I'm flying it with a 1500 4s and it's a little tail heavy since it drifts backwards when I leave it in a hover.

My recommendation is to replace the ESC with a ZTW Mantis 35A 6S ESC and use 1100mAh 6S batteries (thats what I did). The Mantis ESC is inexpensive, has a governor and works very well. Or you could replace the motor with a 3600kV unit and run that on a 2200mAh 3S battery.
MRC really needs to hire a heli expert to sort these things out before bringing them to market. A 450 running 325mm blades really needs 3000 rpm to fly right (especially with the low tail ratios used by Align and their clones - the mechanics in the RotorScale 450s uses a clone of the original Align 450 Sport). Note that I own all six variations of the RotorScales, but have only flown two of them so far - (the other four are still in boxes - yeah, I'm slow!)

OK so the tail blow out is not just me then. Yeah, it definitely lacks power for sure. I can just about do inverted but it requires almost full down collective stick. Not as concerned about that though since it is a scale heli. I just got back from the field and I lost power close to the ground and busted the skids. some cracking on the fuse where the skid goes in but minimal damage otherwise. Wonder if I need to run a ground wire from the boom like I did on my old 470? did anyone else experience this?the fail safe is set to no pulses so I'm pretty sure that kicked in causing the hard landing. Fortunately minimal damage and no gear damage since I was close to the ground. sux either way but whatever. I'm used to it.

FYI, in case anyone plans to purchase the tail grip/rotor assembly from the spare parts page, it shows metal arm and ball joint but it's not metal. it's exactly the same as what comes stock. I told them that and they said the photo was from the manufacturer. Well, do you not check these things? Apparently not. This is not the service I was accustomed to years ago. Or quality for that matter. Frankly, the mechanics on this are subpar. the rotor head sux and needs to be a dfc. I had to trim the fuse around the head to keep it from rubbing.

Agree with everything here especially about the subpar mechanics. Been saying that for a year. If you read some of the reviews on MRC others mention this too. I just received a metal control arm and all metal slider unit tor the tail rotor assembly made by Tarot from Banggood. Have not installed it yet but am going to put the whole as350 project on the back burner. I also suspect a high frequency resonance issue as well. At this point I feel this thing will require a lot of time to get it right for lack of a better term. Got this in early July and would do it again. Love the looks of it and will get back to it someday with a solution. Ran into another guy in Wales who has the MD500. Issues with it and he solved them all by replacing the mechanics with an Align Trex 450.

I’m surprised at all of the trouble with the stock mechs. Maybe mine are an anomaly, but I’ve one had 2 issues. I had a bad tail shaft that was slightly bent. And caused a lot of vibration. Replaced it with an align part, everything was smooth. I also had a very stiff pushrod on the Huey and had to redo the pushrod mechanism. But otherwise my Huey, AS-350, and Airwolf were pretty much free of trouble outside of periodic belt tension adjustment. I did eventually get tired of that on the Airwolf and switched to torque tube mechs.

That's why I'm sticking with my scale Roban helis, not the best but at least they fly great and they fit my budget, Vario may be top of the line and all that, just way to expensive for my taste, yeah if your a builder and have deep pockets, Vario is for you, show up to a scale meet with Roban and you might get a hand shake, show up with a Vario and you they will roll out the red carpet, show up with a Rotor scale and you might be asked to leave...........

There are two sides to this in my opinon:
1. Yer getting a quality scale fiberglass body AND pretty much everything you need to fly it for a fraction of the price you would pay anywhere else.
2. You get what you pay for. I think the whole premise of this rotorscale line was to have something affordable and be able to sell a bunch of them. But you can only make it so cheap without putting in sub-par mechanics.
It flies pretty darn good for that price point. I think this is partially my fault b/c I forgot to connect the grounding wire from the tail boom to one of the rotor head screws to one of the motor mounting plate screws. So I guess it finally after a few flights built up enough static from the belt and caused the brown out or whatever you call it that made me lose power momentarily. I had this same issue on the Trex 470lp and running the wired solved it. I'm so pissed at myself for forgetting to do this and now I have to figure out how to fix the broken landing gear since the skid kit is not in stock and we all know that parts these days are scarce. I guess I can CA glue the pieces that broke and wrap in some electric tape then duct tape on the inside of the body. Hopefully that will get me by until parts become available. If anyone knows of another source or an alternate skid for this, let me know.

Has anyone else experienced this helicopter sorta rocking a bit especially when applying elevator? Is this normal for scale helicopters? Or might it be a balancing issue. I'm flying it with a 4s 1500mah + a piece of steel for added weight in the front, but it still wants to drift backwards a bit and rocks a bit when flying which kinda takes away from the scale appeal.

I will continue to post my progress or lack of here in hopes it will benefit others.
