All good old technic sets are expensive.

My favourites were
The power functions rc bulldozer. That one is great, and is also big. It comes with 3 or 4 motors, so is good for building other stuff.
Lego JCB model 8455- loads of pneumatics. My favourite technics kit of all.
The power function rc dinosaur is also fantastic. It's a TRex and it actually walks and roars. Comes with 3 or 4 motors. Set 4958.

Just wanted to say thanks again - you basically shaped our Christmas lol. Neighbours came around ~23rd and helped construct the T-Rex. It is epic. Just had batteries arrive for the voice box --- the gears click a bit, so it isn't super reliable. Something I will fix - and open to recommendations (can you get metal replacements? :)).

I've also just finished the dozer which is missing a couple of bits. By shear fate @Ahleckz was my secret santa and bought me a mini-dozer which had 2 of the critical parts I was missing lol.

All sorted - little one will be buzzing tomorrow. It works extremely well other than the RF somethings getting confused between channel 1 and 5 but that is not often enough to be a drag.

Thank you!

@dlockers I'm really pleased by that!

Clicking gears? Hmm. It sounds like they are sticking. The clicking sound is normally the gear wheels slipping as they can't turn due to either a jam or incorrect meshing. Look at their housing and make sure it is solid and nothing is blocking the movement.

If you can pick it up for a decent price, the jcb model 8455 is superb. It's got loads of pneumatics (10?) and is a joy.

Generally (though it's been a loooong time), getting a few power functions RC kits, a good pneumatics kit and a truck with a crane (8285 or 8868 are good) will give you a good basis for building anything.

Sorry about poor photo quality, but some old builds of mine.

My own design Wall-E built with combo of Dozer and JCB parts. Was RC and pneumatics operated the head and arms/claws.

That is badass :cry: :D not sure what's more nostalgic the photo bucket watermark or the sky+ remote lol! Love it. Something I can look into in the future :D
 
Does anyone know if you can get better quality gears to replace these? Any slight resistance and they're slipping like mad. I guess they prevent the motor from blowing though!

@dlockers

Metal gears used to be available, but will increase stress on motors and other plastic parts.

The issue is tiny tolerances. If a couple of gears are 0.2mm out of alignment, it all adds up and causes slippage and jamming. Quite often it's a sign you've got a black (sticky) pin where there should be a grey.

Is the clicking when walking or doing the arms/roar?

Edit- can see the two sides aren't balanced in your photo- 2 smaller grey gears on one side, 1 on the other.

Yeah maybe just some refreshed plastic ones may do me OK. The construction is as per construction, the middle gear being connected to the motor.
