Yes I should have done it your way! However yes I do plan to use the steering turn buckles, will have a go at putting them in next weekend. 

All in all the steering and suspension mod seems to be turning out quite nicely. 

I will peruse the forums but am also interested in adding proper steering arms onto my re-re Hornet. 

We all make these mistakes. You're looking at the guy who bought a DT02 set on the cheap for his DT03 and ended up not being able to use the steering turnbuckles! 

I haven't got a photo handy, but I did just this on my kids rising fighter using the spare ball cups, and ball ends from the DT02 kit, and some spare ball nuts and the threaded bar I mentioned to beef up the steering arms on that. I had to drill out the uprights and servo saver to 3mm to get the ball connectors on, but it works great.

Sounds v interesting on the rising fighter mod. 

Do you have any recommended technique to cleanly cut the 3mm rod without deforming it so much that you can't get a ballcup (or nut or other) on? When I cut my 3mm screw (spare screw in a savox servo pack) I had to do a bit of filing to get the ball cup to go on cleanly.

Mine touched the servo when on full lock. I think i could have the hole in the bell crank in a different place. I also took a stanley knife to the servo and sliced some off it and i also turned down the end points on the tx, the turning circle is a little larger now but the arm doesnt touch the servo

I use my bike cable cutters along the angle of the thread then run a sharp edge needle file along any deformed thread. You will always have to do a bit of finishing but it's not hard.

Spin on 2 nuts onto the rod/screwshank. You can now clamp these nuts into a vice or vice grips.

Chop rod (leave 2-3mm for swarf) with boltcutters/Dremel cutoff disc/hacksaw then dress with a flat file to remove squashed metal & sharp edges.

Then unthread the 2 nuts thru the cut area... these reform your threads :)

Ok, so I attempted painting the shell. TS Black. Sanded and "keyed" it, as per some tutorials online. Was using 300 grit paper, finest I could find. Primed it with White, 2-3 coats. Not sure if I've done this wrong but after 3-4 coats of the Black I can still see the effects of the sanding. I might have b*llsed this up bigtime.... might've been the fumes getting to my head.. ...  will post same pics I a few days.

I don't know how deep your scratches are, but your could try some Filler primer on top of what you've done and then go over it lightly with some 1200grit paper.

Actually at total lock on the servo tester the ballcup very slightly touches the corner of the servo. I will play with the setup to mitigate this. 

Minor update, I dremelled the corner of the servo box slightly, just to make absolutely sure of no contact. (...this was a good reason to buy more tools...)

dremels are fun... I want to go and dremel something else...

So just thinking about adding the DT-02 steering arms. Was looking at the steering  knuckles. There is some vertical play here, about a 1-2mm gap...

 

is this also a contributor to slop? Photo below:

A 1mm shim/washer might stop that from moving vertically.

Yeah, I shimmed mine, won't change the world but every bit helps. Worth doing for sure.

Ok shimmed it. Used some grease to keep it moving nicely. There's still about half a millimetre of play but it's a lot more snug now
