I have been hearing a whole lot about these dd tail mods lately and I was wondering if they are really worth it, or if they are hype. I have an 11.1v lipo, if that matters at all for this mod. The only bad thing I have heard is that the motors wear out fast. is this true? how long do they last usually. I also might buy a Eflite CF tail blade so if anyone could comment on that vs the DD mod I would appreciate it.

Thanks

IMO its a great mod,I have had mine for three months and still going strong!Just make sure you get the 50H motor.I would leave the boom full lengh and not cut it.I tried it both ways and I feel the long boom gave me better tail controle

The DD mod is a must have. It's so much better than the stock setup. The motor will last longer also. Like rand said, just make sure it's the motor with the grey end cap.

I did it and I love it. It is an easy modification to do. If you are having any problems go to http://www.bladecprepair.com. It tells you step by step (with pictures) what to do. The smaller tail blade diameter also makes it funner to fly in grass. Try it, you'll love it!

There's also several ways you can install it. If you just want to try it out, get the motor and prop set and install it on the stock tail hub. This is the method I prefer because the GWS fin is very fragile. You can also get the separate fin and hub which is more rugged then the one piece GWS fin.

IMO I would say it is a must have.

I put the DD tail on my heli. Had it on there for a few weeks. Then put the stock tail back on. I like to fly my heli light so I use the TP 900mAh packs. The DD tail made balancing the heli incredibly hard without putting clay in the nose of the canopy. I even chopped 1 inch off the boom and lightend the motor mount. The Plastic on the GWS tail fin is VERY fragile and will break quite easily. In the end my flight time dropped from 15 minutes to under 10. This was not acceptable to me so I've gone back to flying my heli on the stock tail.

In just a few weeks I went through 3 motors. The Quality control on these motors is quite bad. My first motor was great. It ran very cool and didn't even need the heat sinks. I lost that motor in a crash. The other 2 motors ran incredibly hot and burned themselves out in a few flights. If you get a good motor it's great but from what I've seen now 1 in 3 is not good for odds on getting a good motor.

I now use a Futaba 7CHP transmitter with my heli and IMHO it's the best upgrade you can do. With the help of the Revo settings and custom pitch and throttle curves my tail holds just as good as the DD tail did.

If you use any size lipo smaller than 1320 I don't think it's worth it at all.

Yes and No
I installed the DD mod when I was running the stock NiMH batteries. The performance improvement was awesome. Flew that tail motor for months no problems.

When I upgraded to Lipos (11.1V) the tail motor lasted for ~15-20 flights. I have since gone through 5 motors, each lasted about the same length of time (i.e. 15-20 flights). Basically the performance is great but you will burn through motors.

I have changed back to my stock tail, turned the gain way down, it is pretty smooth - not nearly as much power as the DD but at least it is smooth.

The EDP-50 is not the motor part number it is CN12RXC, mnade by GWS. It is only rated to handle 7.2V. It was fine to run it on the NiMH battery pack as it was only 9.6V but the 11.1V Lipos are too much and will lead to premature failure.

See this link for info. on the motors... http://www.gws.com.tw/english/produ...ystem/edp50.htm

Hope this helps.
