Any SR hold outs still left?
Just looking for a roll call on guys sill flying the SR.
I blew the dust off of mine on new years day. Flew 4 batteries of lazy flying. A few flips and rolls. It was a lot of fun.

The only mods to mine are:
401 clone gyro.
9 tooth pinion
Flybar weights removed.
Xtreme tail motor mount with the motor flipped for better cooling.

I think just about everyone has moved on from that piece of plastic poo.

Hmmmm two of my flying buddies just inherited one each and asking me to help them with it. I should not answer the phone :-) when they call, sort of like owning a pickup truck and all your buddies want you to help them move stuff on sunny weekends when I could be flying.

I started out with this heli as my first collective. Sold it to my cousin who sold it to a friend. I too have been asked to rebuild it after a tip over and having trouble with it. the tail just energizes on its own. Any ideas?

apparently the SR esc doesnt like it when you unhook the motor for tests. hooked the main motor back up and tail works fine and flies good for what it is

I still have mine. Might try to get rid of it soon, though, or use it to convert to a TREX 250 clone....

Mine has been in a box since my last tail motor burned out while I as inverted. All I could do was with throttle hold and watch it crash. Not fixing it again. I have crashed it about 10 times. Twice were my fault. I was learning ff at the time. The others have been 1 gyro failure, 7 tail motor failures in 18 months.

If anybody needs some parts let me know and I will take inventory of what is still good.

I need about 20 spare tail motors.

Actually I've discovered that if I limit my flight times to 1 minute I can keep the tail motor from cooking itself to death. I thought about converting it to a brushless tail, but the kit costs more than what I paid for this thing. I tried flipping the tail so the prop is blowing toward the motor instead of away, but doesn't make a difference. If anyone knows some magic, please share.

The flip mod works good with the extreme tail mount. The extra aluminum acts as a heat sink. Make sure your tail rotor is facing the correct direction. If your not getting 30 to 40 flights on one then it is setup wrong. What gyro are you using?

I still have a completely stock SR (incl Tx) that I occasionally dust off for a fly, usually to give a newbie a little hover practice.

Secret for me to get +50 flights per tail motor is to do the following setup with the tail gyro in manual gain mode (not through ch5 on tx);

- Turn the gyro gain pot down to 0%, fully anti-cw. Then adjust the pot on the bottom of the esc until you can just get the heli in a hover and the tail just holds (in a very low gentle hover, not flying around). You need to restart the heli every time you adjust this pot btw.

- Then adjust the gyro gain pot so the tail just holds ok. Turn it cw until it wags and then turn it down until it stops (well almost stops, lol!) and the tail holds reasonably well while flying around. I find that I need to only turn the pot ~15 deg to get it to do this.

Doing this will help minimise the load on tail motor and you will notice a little less bee-buzzing from the tail.

Also helps to limit your flight times, esp. in hot weather, to ~5 minutes and let the tail motor cool down at least 5 min. between flights.

Cheers,
TomC

Mine was setup with a 401. For that you just turn the gain pot all the way down on the esc. Use channel 5 for your gyro gain and set the limit. The trick is setting the limit so that you don't hear the speed up buzz a lot. Seems to run cooler that way. I noticed my tail motors also lasted longer when I didn't spend much time hovering.

My SR is all stock, including the gyro, except for the reversed/flipped tail. I actually have 3 of them, but have stuck to flying only one until I get the tail motor figured out. I'll try your suggestions for setting up the esc and gyro and report back.

Ok, with the gyro gain set to 0, and the proportional all the way as far plus the tail wasn't putting out enough power to hover. When I added a tiny bit of gain I could hover fine but there was a slight tail wag sometimes. The tail motor seemed to stay cooler this way. Before I touched it, the proportional was already all the way +. I wonder if there might be something wrong with my proportional.

Might be because you flipped/reversed your tail. Not really too sure because I have just left mine stock. Also, could be an early indication that your tail motor is going to fail.

Also, remember that you must re-start (= unplug your flight pack battery and then plug it in again) the heli in order for any changes to the esc's pot will take place. You can adjust the tail gyro gain ok without a re-start though.

You did reverse the polarity of the motor power wires after flipping the motor right?

Yeah, I flipped the polarity. I fiddled with it a bit more, and was able to hover it a bit with the gyro gain at zero, but I'm not that good at it. It appears that sometimes I have to give left rudder and other times right rudder to keep it stable. I tried slightly different settings on the proportional, but they all seemed the same. I guess if I practice a bit more I'll get better at it and be able to tell where the best setting for the proportional is.

If your flying skills are not quite up to this and you do not have anyone local who can help maybe try attaching the heli to a lazy-Susan. I have never tried this but I hear it works.

My flying skills aren't quite up to it, but I'm getting a lot of good practice trying, and so far the tail motor has lasted through about 15 to 20 charges. Unfortunately I just broke a blade grip and lost the piece so I can't try to glue it. I'll now have to fly my 400 3D until I get a chance to stop by the hobby shop.

Should I bother to get aluminum blade grips, or stick with plastic? It seems that plastic might be strong enough since they lasted through so many crashes already.

Also, my 400, and 130x seem so much easier to fly than the SR. Is that normal, or have I just crashed this poor SR too many times? I'm thinking the 400 is easier because it's bigger, and the 130x is easier because it has a computer in it that is helping me quite a bit. Could this be the case?

I'd stick with stock plastic replacements on the SR. Not much sense turning it into a little money pit imho.

Properly setup the SR should fly well enough for hovering and small circuit training. Beyond this you are better to use other, better heli's.

I would personally recommend that once the basics are mastered with a sr a guy looks at a mcpx-bl for a bit of low-risk advanced moves and then look at a 450x afterwards.

Hey be nice.
They are great if you want to learn how to fix a heli. I put a little effort into mine and it ended up having amazing performance. Belt driven tail rotor conversion, e flite 420 brushless, ar6100 rx, and configured it on my DX 8.
