WPL, JJRC and HengLong R/C Truck thread

[tonycocacola]

I've come to a halt with my Defender, due to lack of time.
I've changed half the suspension for ball and rods, and I have the paint ready for when I can spare some time. Need to order the bits I need to finish it off.
Don't know when that will be though.

🤔😀

There's been a few changes with the red truck. I've swapped the shocks on the rear for ones with more travel, this necessitated new bell cranks to change the geometry. I've got even more flex at the rear now.

The front needed getting to a similar standard. The drilled shocks certainly improved the flex and particularly droop available, but there was no support left for the actuating rod and this would flop about and sometimes jam. I've made some extended shock bodies by drilling out a pair of WPL parts, and gluing on the bottom half of another pair. Longer shafts were made from wire nails with an M3 thread tapped on the end.

I've also made the new rear bumper/irons/spare wheel carrier assembly. This sits the spare somewhere in between the previous two positions. The rear bumper got mounts for another pair of those big funky shackles.

Went for a walk down the beach today and took the C24’s with us .

I got fed up with trying to get the cantilever rear to work properly. These trucks are just too light, I think to work with the resistance of the damped shocks oil seals. If I had the springing or lever at a point where the suspension would return the truck couldn't compress the springs - If the truck compressed the suspension, it wouldn't return to ride height.

So I've made another pair of extra long/extra droop WPL shocks for the rear. I have nearly as much travel as the cantilever set up. I'll have a play with mounting position, spring lengths and alternative springs (pen/C14/24) and see how we go from there.



I've also relocated the front suspension pick up points further back, and lower, to lengthen the radius arms - I've always thought that they looked too short. This does seem to allow the front to flex more smoothly and has the ride height now with the arms at their longest, which pulls the axle back towards the truck on full compression, helping the steering servo clear the body.

I've just set 3D printer purchasing back again.



It's an RBR/C 1/12ish crawler frame chassis.
I've ordered a WPL front axle case to go along with it and a set of steel pinion/ring gears. The rest I think I can build from parts in stock. Build commences in a fortnight I hope.

The first of my D12s arrived yesterday, apparently even multi orders are all despatched as separate items, excited about the pure size of it! I couldn’t have a play as Ethan was around and needs to stay a surprise until Christmas .

Saw this and thought of you

Quickest £13.56 I ever spent! Thanks

The frame chassis arrived, I got all enthusiastic and did an unboxing video.



It didn't quite go to plan!















I've cut the frame where it was too long and bent it back together - over bending it so the gap springs closed, with a little blob of CA glue. I doubt I bother welding/brazing it.

I progressed with the build up yesterday. Having decided against using the stock C34 Km gearbox, I've pulled the metal single speed out of the orange C34. I think I'll rebuild that with out spare two speed as a tow wagon for the frame chassis and build a trailer to suit.

The frame currently also has the C34's axles and suspension.

























It's mocked up on wpl shocks at the moment, but I'm going to have to modify these and the chassis for it to work with them. Particularly at the rear where they need to be significantly longer.

[markbognor]

Well I built it up, broke it and sold it. Bit of a win actually, after contesting the £20 refund offered by BG they refunded it outright. Then I sold it for £20.

It was a bit of a horror. You can't fit the links or motor with the body panels in place, and can't get to the nuts on the rear of the body panels as easily with the links fitted. Speaking of fitting, none of the parts really do. The servo mount axle truss is actually ok but the rest a bit rubbish.















Next project is a leaf sprung C34. I'll need to make some GRP spring hangers and use the aftermarket upgrade parts as well.

I’ve been thinking on the trucks and the way they are and after seeing how well Mr Bognor’s trucks run on 3S lipos some work is in order. First up I got some duallies for the GMC.



I’ve pulled the twin boom wrecker body from the ZIL next. I plan to rework that to run on the GMC.





Started to chop up a proper Q60 bed. Out the box they are too narrow but the length is right enough and I want the swingy tailboard on this truck.



Started to placca weld it all back together with some sections from a Q61 bed.





Added some detail with a correctly-to-blueprint-ran exhaust, widened tailboard, fuel tank, towing pintle and the trailer/crossmember bumpers. Now, I’ve ran out of primer and I need to get more before moving forward.

Ævintýri í smáum stíl Tundra Tours are go...eventually when it gets here - I'd best get a C14/24 chassis built up.

There's a pre release C54 - 80 Series Land Cruiser - body on its way, also a set of the new wheels and tyres. I don't think I'll put them on it though. The tyres might go on the dually wheel slot mags that are destined for the shabby leaf spring FJ40 project.

[markbognor]

I started building up a C14/24 chassis ready for the 54 when it arrives. In an idle moment I propped the C24 body I have here against it. Having not really like the look of them before I might have to give one a go.

[markbognor]

Similar wheels with V1 tyres...

C54 is here...

[jethronz]

Think its too small for those wheels Mark.

How soft are the new v4 tyres?

[Rich]

Had the TBS mini and program cable arrive so I've been playing with that..



No prizes for guessing where the sound files came from. The horn is trigger-able on channel 3 while channel 4 starts and stops the engine. Neat-o.

I think it's supposed to look a bit of a characture. But it will jo doubt get tried out on several sets.

The V4 tyres are very soft, slightly taller than the V1 but not quite as tall as the V3. They have very soft side walls and will have the same tendency to roll over themselves that the V3's have. The tread isn't as wide as the V1 either. I'm not a huge fan currently.

The C54 is now on an MN99s chassis and will be getting the lighting from theat too.






The MN body is going on the C24 chassis, it'll need the front axle pushing forward a little, and the MN interior trimming around the gearbox. I plan to cut the MN interior up quite a bit anyway, so that a 12th scale figure can fit inside. It'll also get C34/44 seats rather then the completely out of scale buckets they have as standard.
