Repair maiden didn't go so well

Belt, TT, I have two of each bird.. doesnt really matter. They both fly fine.
As for the OWB and sleeve, if you can afford it.. replace them. With a hit like that on the gears and shaft, I wouldnt take a chance. On a 700, the hub/OWB is like $90.. on a 500, its very replacable at like $24.

$100 crash.. yep, thats about average for the 500.

Trex 700... main blades 89.00 owb 89.00 autorotation gear 25.00 tail boom 30.00... trust me I know.

I've been pretty lucky so far. I've crashed this 500 a couple of times. Usually just main gear, boom, flybar, and shafts. Much less than $100! A little more if I get the blades.

I'm going to replace the sleeve and OWB. Basically everything that touches the main shaft, with the exception of the main rotor block will be replaced.

I just haven't had good luck with my Tarot TT Tail. I've had it on and off a couple of times and everytime I install it something goes. Nothing I can really point to and say AH HA but it's coming off.

Tonight is re-install the servos night. I'm going to cut the wires to length and install braiding.

You don't need to cut them... you can fold them over to make them shorter, and slide the braiding over them.. I do this alot.. especially on my 700... the connector on servos and such come off really easy. If you look closely, little plastic tabs or fingers are holding the pins in the connector. I just slip the blade of my Exact-o knife under the plastic tab, raise it just a bit, and the pin slides out. I have taken the connectors off and installed the braiding AND the shrink wrap, doubled or triple folded the wire for length, then reconnected the connector. Its alot easier then it sounds.

I used to have that problem till I started holding the driver between my thumb and index finger only. I screw it in till it stops then pulse it a few times.

Motor mount holes are still the bane of my existence though. I started just installing headless screws in them with red locktite to protect the holes from being stripped. I put the locktite on the screw and screw it into the hole then put a nut over it and tighten it a little to tension the threads and keep the screw straight (after it sets I remove the nut) Then I stick the threadded posts through the motor mount and secure them with nylock nuts.

I came up with this I when ruined a motor by stripping one of both sets of holes. In that case I actually took the motor apart and with a pair of small pliers and lot of swearing screwed on and locktited nuts on the backs of the screws for extra security (didn't trust the partially stripped thread alone to hold it) I liked the results so much I now do this on all my motors. If I ever need to remove the screws a soldering iron and a set of channel locks will remove the screws.

If you have a OOB removal tool and a clamp or vise (or an arbor press) you can just replace the bearing without having to buy the whole case.

True that.. but.. his took such a hit.. it literally cracked the sleeve portion of the auto gear right off...and his hub lost a screw that really notched the hub, last thing he needs right now is to just replace the OWB.. and wind up with a bent hub wobbling after all that rework.
I agree totally, in usual maintanance, I just replace the OWB with my press.. very easy to do.. but for $24.. just replace the entire hub with bearing. With a hit like that.. take no chances...especially for $24.
If it was my 700... with the hub/OWB costing $89... THEN, i'd do a piece by piece replacement as things are needed.

The one way bearing and gear shaft are out and seem OK. However I'm going to replace them. With the severity of the crash and the relatively low cost of those parts replacing them will make me feel better.


I've got one servo installed. I'm shortening to length and braiding the servo wires but I only had enough connectors for one servo.


I also repaired the canopy. I need to sand the JB weld so it will slide into the bottom frame receptor. It will be a servicable spare. I'll use it on the repair maiden!

Looks like it took a Viagra
