Default Blade SR Tail Motor

So Ihave had about 4 batteries through my SR now, and it seems as though the tail motor just went. It won't come on, and if it does, it only spins real slow. Adjusted the gain, and no help. Has anyone else had the tail motor go already? I also thought that it mught be the 2 in 1. Just trying to see if anyone can help me out, or if they have had the same problems. Thanks

I have a Blade CP Pro 2, and I believe the tail motor might be same. I'm on my 4th tail motor, and one of them had similar symptoms yours had (perhaps not quite that slow, but not fast enough to prevent the heli from spinning around).

HH says that they believe it's the 2 in 1. I guess we'll see when it arrives.

Electric Tails seem to be the bone contention...I am not experienced but can imagine from the MSR what a larger version manifests in problems...

There evidently are mods ALREADYout there...Irefer to http://www.electric-rc-helicopter.co...pic.php?p=9447
I like what this guy has done, and imagine it will be cheaper (and more stable) than replacing 10 dollar motors every few weeks.

Quoted below,
.

The electrics allow only a tail servo (currently a Futaba S3114 analoge) to be added. Simply unplug the tail motor, unplug the signal plug from the gyro to the esc, and plug in th new servo.

Mechanically: a custom made alloy belt pulley and retainer for the main gear, spacer to drop the main gear slightly, an idler block for two flanged bearings to guide the belt down the stock boom, custom made belt, and a complete Skyartec tail unit (currently metal, will try plastic when I have more parts).

I adjusted the servo push rods (about two full turns each) to compensate to the main gear spacer, which lowered the head about 1mm.

It is totaly reversable with only three 2mm holes drilled into the heli. No other modification required.

Total weight, including battery, 370 grams.

Flight testing is continuing and hope to have some data (amp draw, flight time ect) and video this week.

Tail holds well and is precise. Flys best on idle up or flight mode 1 (higher head speed). I guess with a digital servo (the stock gyro has digital output) it will work best.
Like the rest of the heli, the tail responds nicely to stick moments and will suit the begginer."


That's the way Eflite should have made it, me thinks

I have not tail rotation now either. I am a noob, so Ihave the training wheels on and have yet to even lift off (inside still). Out of nowhere, the tail has shutdown ... I adjusted the ESC gain a bit and still nada. Calling HH tomorrow.

1. HH only open weekdays.
2. Over-the-phone diagnostics indicate a bad 2-in-1 also.
3. Excellent service from HH

I just got the sr two days ago, and the tail motor just stopped spinning out of nowhere. Started the heli up, it was fine. Started it up again, and nothing. No crash or anything. Just didnt work. Have to go to the LHS monday, and get a motor, and see if thats the problem. I just hope its not the ESC. That would suck. I just have a hard time believing that the motor would quit only after 2 days.

My CP Pro2 did the exact same thing. I'd flown it numerous times and was actually working on my hovering in the bedroom (3 minutes in) when the tail started going out. Luckily it went over my bed so I just shut it down and it parked itself against a pillow. From then on it was intermittent or completely absent. I wasn't sure whether to blame the tail motor, gyro, or 2 in 1. I took one of the batteries and used jumpers to hit the leads on the tail motor and it fired straight up to full tilt. So at the moment, I'm going with the 2 in 1. I'm glad to see I'm not the only one that has had this problem.

My tail is still dead. HH thought it was a bad 2in1 so they sent me a new one. I replaced that and still no tail. Gyro lights fine. I tried the AA battery across the tail motor leads and nothing, so I am guessing it's a bad tail motor - after about 2 minutes of operation - really!? I have new tail motor coming ...

The support fellow gave me the option of sending the heli in or them shipping me the part. Dunno. I think he said he felt bad that the heli was out of commission so soon and wanted to get me going as fast as possible. I have yet to leave the ground. The new tail motor is not coming from them (I have yet to call HH about this) - I ordered the new tail motor from a nearby online retailer.

I've had an Axe CP for nearly 4 years. The tail motor is the same on the SR, the CP Pro 2, and the Axe. Those tail motors just don't last. My solution was to install a HH gyro with a brushless ESC and tail motor. The last 2 years have been alot of fun.

Good luck.

Pilotlight can you be specific about the parts you used to go brushless? I have about 10 packs on my SR and so far no tail motor problems. From what I had been hearing from everyone else it is only a matter of time. I am most likely going to go for the belt driven setup as I can use this with the stock Tx until I can get a DX6 or DX7. Thou I would consider the brushless setup as an option If it can be made to work with the stock Tx. Is the beltdrive shown above the one from Freestyle-Hobby.com?

Unique,

I had a tail motor go out on my SRafter about 20 packs. Here are my observations from another thread Ihas posted:
