b42 SD v2

New pics pls!!!

after my first test today I know that I need to loosen off the diff and it does not run it in the wet very well. I will upload some more pictures tonight when I've put the motor and esc back in as I had to take the esc and motor out as my b44.1 motor unsoldered it self so I had to do a quick change over. I was using one of my b44.1 shells and it fits well, i also have a jc front wing to add. I think that it will work much better in the dry like all 2wd, I will give it another go in the new year with a few of the changes that I will have made to it.

[alex97]

long time since an update but nothing has changed until today. Seeing that since the last update 2 more chassis have been released that use the b4 front and b44 rear and seem to have been doing well I thought I might try this again.

In January I bought a alloy chassis for a b44 off of ebay for 99p, most likely because it was bright pink. The plan was just to paint over it but I striped the paint off and sanded it down so it has the brushed ally finish but I am thinking about getting it powered coated black.

All I have done so far is mounted the rear end and drilled the holes to mount the front. With this chassis I will be able to change the chassis length, im not sure what the difference will be between each hole for the chassis length.

Now for the picture, nothing else will change but I hope it will be ready to run so I can give it a go at Stotfold in two weeks time. I will update this when more happens.

Bit more done. The tires are not glued on so the tires so that's why the camber looks off.

Nice!

Hmmm... I have an unused B44 alu chassis...

[learnerdriver]

most current b42 turn the centre diff and motor mount through 180 degrees and put the front deck and associated front centre drive shaft on the rear

however that does mean that you also have to flip the rear diff internally to get the correct rotation

the above design does limit you to shorty lipos though

[alex97]

I wanted to keeped it the b44 layout for better balance and balanced weight over the drive wheels. I'm about to do my wing mod so that I use screws to keep the wing in place. I'll be using a b44.1 shell as I've got two spare. I'll keep this updated over the next few days.

sorry for the poor quality image but ive got the batterys in

[alex97]

Just added some electricts and had a play in the garden, I'm not sure if its the tires but it was very hard to find any grip at the front. I was using some new blue mini spikes and I'm not sure what the fronts are called as they came with the car (the ones in the picture). I think if I get some better tires that might improve it but I was only running on grass so it might be different when it comes to astro or carpet.

Hi Alex

They are Cut Staggers and great for astro/carpet high grip. Not so good on low grip and grass, try some mini spikes. Blue is very hard I would use yellow for dry conditions silver for wet.

[alex97]

Thanks, I'm only testing so don't want to use my yellows. I've just put two packs though the car and after some front suspension changes it felt very alright but I had no grip roll and it was very hard to make the car spin out so I've got something right. The only thing I didn't like was it in the air, what ever I did it would still nose dive. I wasnt using a wing and the receiver was right at the front so maybe making a few changes there might help. The amount of kartwheels and front flips that I did showed how strong the car as it was fine after evey crash. I'll upload a picture later of it in its current state.

You might need some weight between the batteries, I did!

Stiffen the front with blue springs and 35 wt oil and outer holes on lower shock mounts. Stand the rear shocks up using inner arm holes and soften the springs to green or black with a 25wt oil. Try disconnecting the anti roll bar as well.

[alex97]

It has the brass battery tray. I'll try the shocks later thanks

[alex97]

After another pack though the car and im very happy with it so far. So far I have only tested it on grass and other than the steering I don't have much more work to do on it.

I looked at doing something but useing a x factory x6 front end with associted as its one part and kicked up. That bolts on so no cutting a b4 up. And before any one says anything I know theres a x6s. I just wanted to use parts I already have laying about.

[alex97]

whats the difference between the b4 and x6? I have another chassis that will look better and better designed for the b42 sd, this is a while off as I want to test the current chassis first. The name change is to make it easier to say and for people to know what they are looking at. The SD part is for the saddle packs.

[alex97]

I wont be carrying on with this any longer as I just don't have the time and it does not suite the tracks that I race on. I will be selling the b4 front and b44 rear as a pair. they would be perfect for a x6s or a cobra chassis.
