Just online looking for some stuff to modify my new wot 4 foam e (don't ask me being lazy (again) ) and I found this amazing site. It may appear a bit nerdy but I am soon to order:

 

M3 200mm x4

M3 150mm x4

M3 100mm x4

M3 nylon nuts x50

M3 nuts x50

M3 washers x100

M3 domed nuts x50

 

For £12.61 (inc postage) http://www.technobotsonline.com/

 

I will also put a post up on forum as it may help someone who needs to do the mod. The site I found is http://www.rcgroups.com/forums/showthread.php?t=1297511&page=19

 

Anyway, coming home from Sri Lanka tomorrow so I'll see you all on Sunday.

Model Fixings is also a good source for small screws, nuts, studding, etc. Good quality stuff, too - quite a lot of screws sold through the model trade are not great. OK for small orders too as minimum postage cost is quite low - a few pounds.

Incidentally, which of the mods described on that thread are you actually doing? The undercarriage reinforcement with plate inside radio compartment and two threaded rods? I have done that (albeit with 4mm plywood rather than plastic) and it works well. I don't think there is any need to use nylon nuts designed to strip as described there, though - I used regular nylocs, and even though I've bent the threaded rods and split the plywood, it didn't cause any extra damage to the fus through the undercarriage not yielding. I have since used some 60mm M3 socket cap screws from Model Fixings going into M3 T-nuts in the plywood, but actually this is less good than my original approach with M3 threaded rod, one plain nut permanently threadlocked to the top, and a washer and nyloc on the bottom. Lining up the screws coming from underneath to hit the holes in the plywood is tricky!

Yes I'm doing the u/c mod. The nylon nuts are there because I cracked the ply and damaged the foam in the rx bay in an emergency landing as I got a "signal loss" warning. It takes 2 secs to replace the nuts and not a day to fix the fus. Also, can anyone remember how long their bolts were???

I have used Modelfixings for many years now, always good fast service, great range of product, good quality. Running the large club I do means I get through lots!

 

They are one of the few sources of small .1mm step allen keys, useful to get a small stretched headed one out where the original is made of Cheesium or worse, Align-ium.

You need a thicker bit of ply, then! I certainly have cracked one bit of ply, but it's not hard to make another, and you could always make a spare and keep it in your box... Generally I find that the undercarriage is the one bit that survives when I crash yet another WOT-4 foamie!

Having just looked up the relevant Model Fixings order, when I was using M3 socket cap screws they were 60mm long. However, that's only enough to get through into a T-nut, not to protrude the other side as you'd need if you're using studding with a plain nut on the end. 65-70mm is probably about right, but personally I would measure it to be sure (use a spare bit of pushrod or something, a pen, and a ruler). I can't get to the old bits of studding right now to measure them. If you're using the breakaway nuts idea then the length becomes quite critical.
