If you bought the kit recently, I know a lot of hobby stores are including the new black tail gears with the kit. It wouldn't hurt to ask the shop you got it from.

Can someone please explain the significance of the 110 vs 112 main gear and the 21 vs 22 tail drive gear. They have both options in the new black gear. Im about ready to make my purchase but can't decide.

I didn't notice different teeth counts when I ordered... I'll see what I receive tomorrow, I expect the ratio to be the same as on the stock one, here's what I got :
http://www.fxmodelrc.com/H70G005XX-P...nt-T-rex-700E/ I also got the other two parts for the front black gears, but I don't think I'll use them... I don't plan to use my 700E as a wood cutting machine. Whatever, didn't have any issue with the stock setup, so in doubt I'll just leave it as is. |

Boycott Align?
I have a 700 DFC on order through my local hobby shop. I called Assurance to find out if kits shipped in the past 7-10 days have the updated tail parts. I was informed they DO NOT and will not. You must pay extra to purchase the updated parts!?!?!?
This is a very serious issue and I think Align, as well as Assurance, is grossly underestimating the liability they face when one of their machines fail; causing injury or death. I have cancelled my order with the hobby shop and asked them to return the kit. This is not an issue of money. $20 to $100 doesn't make or break any of us. This is an issue of a manufacturer NOT taking responsibility for a defective product. Worse... they don't care what happens to their customers. SHAME ON YOU ALIGN & ASSURANCE!!! |

I think there is a difference between the DFC electric and DFC nitro gearing. I know the front tt gear set had a different version for each model.

This store sells the 700DFC with free upgraded tail parts and free batteries as well. My buddy got one from them recently. I think depot includes them as well.

If anyone else is encountering the same problem as I had with the new tail shaft having side to side play, I found a fix for it. It is the Kyosho 96046 6x8mm shim set. It comes packaged with several of each thickness (.1, .2, and .3mm thick) shims. My tail needed a .1mm thick shim to eliminate any play and get the gear mesh perfectly smooth. As I recall, it's somewhere around $5.00.

The tail shaft issue is resolved with the new gears? Mine are ordered up. Thank you all.
Whatever became of the 'cupped washer' issue- does that matter anymore? |

For the most part, yes. Reports are good, and my setup was good on the maiden last weekend. The washers have been replaced by harder, thicker washers and hence shouldn't cup any longer.

The mesh on the new tail gears is a little tight but they will wear in nicely after 2 flights. You won't notice it in your flights

I only found the mesh tight in the instance where the tail shaft was loose. When I added the .1mm (for the first one, and .2mm for the second one), and reassembled the tail box, the mesh was smooth as glass. Also, I did not over shim so that it forced the tail shaft gear away from the umbrella gear.
If I moved the tail shaft by hand before I put the shims in, as soon as I backed the shaft tight against the bearing on the bevel gear side, all roughness disappeared, and when I let it go, the roughness returned. After installing the shim, the tail box went perfectly together and the shim moved the shaft back just enough to remove any roughness and stop the play. FWIW, there was a thread on this very subject a while back on the 600 heli and the shim setup worked perfectly in that case to remove the play. I've got at least a couple hundred flights on it and no loosness has returned.

Yep, that's pretty much the same way mine is. If I push it back toward the bearing on the gear side, it's relatively smooth. In the end, I just went ahead and flew it today. The vbar vibe log didn't show any significant vibrations and it flew just fine.

700 DFC tail issue
I was finally able to fly mine today after installing my new tail drivetrain. V-bar logs were a lot better but, the end play in the tail shaft was enough that it caused a tail wag with no stick input. I am now waiting on a shim set from A-Main. I can't wait to really be able to fly this bird to its edge with confidence. It's been a long wait, hopefully it's finally over after my shims get here.

Mine is ready for its maiden. If I can just get the weather to cooperate. I suppose all you northern fliers will call me a wimp, but it's hard to fly when your hands are shaking with cold.

side to side is normal that is the thrust bearings at work, if you over shim it the bearings will lock up causing other problems like a vib or worse.
also the tail gears should run smooth with a tick of play in and out play this is in an unloaded on the beach once you spool up the gears will load and run smooth, if you over shim the gears in the tail box and preload them the load when flying will cause them to run tight, just how i set my tail up and never had an issue if you are doing it different and its working for you then thats fine just a different approach to the tail
