Cheers Joey.
The axle on the far side is an M2 countersunk screw attached through the servo casing,then through a small fibreglass plate,to stop it from distorting too much.Its alot more rugged than Bruces old one,which was a screw superglued onto the outside of the servo case!

I found a supplier for the battery here...

But they are out of stock!!!! :-?
Bloomin typical! :(

Just a quick pic of the front of Bruces lifting arm...

A nice chunk of 4mm polycarbonate armour,much tougher than before. :)

It is hard to see, if you don't know where to look :P

looks good Jim, although I do think those arms will break before the polycarb does! looking forward to seeing and fighting it (having ordered lots of parts to build a new flea myself, can't resist the urge hehe...)

i see it :) it's looking awesome!

for all who can't see it its on the front of the flipper at the bottom. it's been roughed up so it looks white (therefore camouflaged)

Sorry. I had to sand it to follow the curve of the flipper.(I generally lightly sand everything anyway,just to remove burred edges etc.)
Cheers,Jim :)

Looking good Jim :) are you going to have metal armour on the lifting arm or only 4mm polycarbonate? just wonder if Bruce meet a spinner.

Thanks "TheAntTrap"
I shall be running away very fast from spinners!!! :D
I will see how much weight I have to play with after fitting all the vital pieces.
I am thinking of making the internal structure as strong as possible,and then having a destroyable 1mm polycarb armour on top that can be replaced easily.

I am just waiting for fresh stocks of fiberglass board now,to complete the chassis pieces!! :roll:

Finally got the fiberglass board I have been waiting for,and have made the chassis sides and added a few bracing pieces.The original bruce chassis sides were much thinner,and were bonded together using lowly araldite rapid 5min epoxy resin as shown here...
Image

But the new improved Bruce chassis is bonded using a decent 2 ton "clear weld" epoxy,and with the bracing pieces should be much stronger...

Weight is...45.2g so far,so should be fine by my calculations.
Cheers Jim :)
