My Top Force built up for Boondal

[MAD RACER]

Well I built this up about 5yrs ago.  It's what I call a Bitsa build but some serious R&D had been put into it over that time.

I was going through all my spares that I acquired over time from my Rays & Terror Conquer and relized that I had almost enough parts to build another Top Force. I had a Top Force but was a New Re re and didn't want to run it so this was a good way out. I wrote a list of parts that I thought I needed and went to work in purchasing them. From memory it came to around $150 . I had lots of sticker sheets from JR RC store when he was selling them at stupid low prices and a non genuine shell from Canada.

From the out set this build was with our bumpy slippery loose dirt Boondal track in mind. With a few tricks thrown in of my own.

Shocks are Yeah Racing 90mm shocks front and Rear. Losi springs and drilled pistons

Ball diffs front & rear while the front is a new TA03 light weight diff being used.

A Yeah Racing alloy centre shaft being used

AE B44 battery tray was grafted in recently for the saddle packs and a low profile steering servo to allow room for the esc to be in the middle of the centre line.

A 9T Ez Run combo gives the tyre shredding power.

A Yeah Racing Alloy Motor Mount and Diff Cover.

Losi Stud tyres on Top Force Wheels. Top Force Universals all round.

The rear end is where lots of research and trial & error of components . ( Axels and correct alignment )

I wanted more rear grip then the original rear hubs offer &  more adjustability in roll centres . So after 3 different attempts of doing this mod I ended up with a set of Yeah Racing alloy M05 hubs with 2.5d of toe in. ( This is why I love Tamiya parts ) I wanted vertical  mounted ball studs too as I feel this aids rear grip as well as the toe in which is critical . Mega traction was the end results with a re drilled Roll centre ( Camber Rod ball stud ) pick up on the rear tower to get better geometry through the suspension range.. It's almost like a trailing arm set up with only a .5d of camber change throughout the suspension travel. So much traction I had to stiffen up the rear end to stop traction rolling.  This mod has since been performed on my Rays too.

The front end had a Evo copied front tower but it gave too much steering as the shock tower is a little shorter so the original was put back on. 

So how does it go. Simply awesome.. Has lots of grunt with a good top end. Traction from front to rear is very balanced and very predictable . I recently played with diff set up's to get a better balance and feel there is very little more in tuning to do.

Well its a Bitsa but nothing is rough and looks like a original Force so I'm really happy with it.

Please detail me the rear hubs with closer pictures if you can.

I'm really interested in.

 

Many thanks

Nice one Mad Racer, the Top Force is such an under rated car, I bought one, hopped it up past Evolution specs and then bought another  lol, it has to be the most driven buggy of all my runners

Did you feel a handling improvement going to the saddle packs?

 

Do you think the alu driveshaft is an improvement on reciprocating weight?

So, this post changed my plan of buying another rere Egress into getting a rere top force instead.

Too late for that, I bought a nib rere top force five minutes after reading mad racers & snappy1's posts

+ I've only been freebasing Tamiya for a few months, so I've got a lot of catching up to do.

Saddle packs has definitely  made a difference. It Changes direction so much better and just feels a little more planted.

Light weight front diff was only put in due to the cost savings . With brushless motors and Li po's there are no advantages maybe in 17.5 or old brushed motors

Max you need to read. I mentioned what hub carriers they are !!!

[Snappy1]

OK, thanks, I'll have to look at the saddle pack swap over soon.

 

I really went overboard with reciprocating weight on my TF, TA-03 ball diffs front and rear, hollow carbon fibre gear shafts front and rear, carbon fibre driveshaft.

 

It has original Evo upper and lower decks, with Fibre lyte front and rear carbon Evo towers.

 

My second TF has evo lightweight diffs front and rear, both run hi caps.

 

Do you run a splitter at Boondal?

That is one of my favourite threads on Tamiya Club.........

[MAD RACER]

No Snappy.

Boondal is a  loose surface. So much so I run one grade harder compound tyre up front . EG  Losi silver compound Studs up the front and Losi Red studs at the rear. I don't like a over steering set up at all. All my cars are set up like this. Seems to suit me. Most others that run do the same.
