I thought I read someplace that the tail should be upgrade to prevent failure? Not sure if this was only associated with the DFC model or if it applies to this heli in general? I have had to red lock tite the set screws on the tail of this heli because they kept coming loose..

Some of the original trex 700 tail hubs/screws were a bit on the weak side. however, It was more of a problem as powerful electrics running a high head speed became more of a norm.

the newer grips have and extra bearing and a beefier tail hub.

they also made changes to the gear ratio and tail output shaft to keep it from shearing.

just depends if you have a newer kit or and older one. if its the latter i would upgrade a few things.

It's a trex 700 fly bar.. The 1st ones to come out.. So I should upgrade the entire tail.. I don't mind that it is fly bared....at least for now... Anything else? I'm the type a guy that hates to crash secondary to mechanical failures.. I fly cautious

I would agree to upgrade the tail, but only after you crash for some other reason. The tail on the 600 and 700 are pretty much the same on older versions. Both had a 5mm axle for the blade holders. The 600 had plastic grips, the 700 aluminum. On newer versions they both now use a 6mm axle instead of 5mm. You cannot find aluminum blade holder spares for the 5mm axle. I just went through this and replaced the whole thing with the 6mm unit for about $27.00.

If as you say you are a cautious flyer, you will do as we all do, and perform a good pre-flight check on your entire bird including the tail. This means testing little screws with a screw driver. Then just fly it.

I have crashed my 700 once and my 600 four times. None of these were caused by mechanical failure. These are some pretty solid birds. Crashing is an opportunity to upgrade.

I also still fly one of the orginal Trex700N Pros. I have yet to have any tail issues of any sort (knock on wood). Mechanically, it's a very solid machine that does not require alot of attention.

Just needs a good maintenance check before each flying session and a QC before and after each flight to catch any losened hardware. It'll be a good machine for you. I love my 700
