The Knight 51 Posted October 16, 2014 I need for my body shell a wheelbase of 245mm. But the latest F-150 kit is 255mm. So I try to change the front arms. But which one I should use? I search in google but find not much. On one page I have read that front arms from FF01 should suit. Is that right? Have oneyone experience in it? Share this post Link to post Share on other sites
z00ter 392 Posted October 16, 2014 I think you are looking for the ff01 swb, was a clio and a vw golf which I believe had the 245mm wheelbase pls see this for someone who went from ff01 swb to lwb gives u idea how it is achieved : http://www.tamiyaclub.com/forum/index.php?showtopic=632 Share this post Link to post Share on other sites
Thommo 1217 Posted October 17, 2014 TA02 - 257mm TA02T - 255mm TA02T with the rear arms (TA02T / TA01 type) flipped is - 237mm (I think but someone like redzone might be able to clear this one up) The closest I know of is a TT02 chassis built at 251mm Share this post Link to post Share on other sites
The Knight 51 Posted October 17, 2014 nonono, I do not search for a chassis, I search for suitable front (or rear) arms, which brings the wheelbase from 2xxmm to 245mm on a TA02. Share this post Link to post Share on other sites
Percymon 2184 Posted October 17, 2014 You can generally get away with 5mm difference in body wheelbase to chassis wheelbase, but no more. You could shave 1-2mm of plastic from the inner / outer ends of the wishbone parts both front and rear to offset them towards the middle of the chassis. Do the same with the front C hubs and the rear upright parts and you'd get pretty close to the 245 you're after. You'd have to shim the non shaved ends with suitable spacers to save them nmoving along the screw hinge pins, but thats easy enough. Share this post Link to post Share on other sites
mr crispy 2293 Posted October 17, 2014 It maybe possible to start with the 255mm configuration and then trim upto 5mm off the rear on the front arms and upto 5mm off the forward of the rear arms. Use spacers to push both arms inwards as far as they will go. How precise does the wheelbase have to be or are we talking ball park here? It would be very useful to those of us that like modding chassis and swapping arms if we set up a sticky or pinned reference thread where we take measurements of parts like suspension arms, shock towers, C-hubs etc and list them with the chassis's they can be found on.

dutch_rc 71 Posted October 17, 2014 Swapping the rear arms of a TA02 for TA01 parts will bring back the wheelbase 20mm. It'll be at 237mm that way... Share this post Link to post Share on other sites
The Knight 51 Posted October 17, 2014 no one have FF01 to look? Is it possible to swap rhe front arms of ta02? which dimension would it have? Share this post Link to post Share on other sites
redzone 212 Posted October 17, 2014 Swapping the front arms won't do anything! Share this post Link to post Share on other sites
redzone 212 Posted October 17, 2014 Ps I thought the ta02t is 250mm wheelbase? http://www.tamiyaclub.com/forum/index.php?showtopic=68066 Share this post Link to post Share on other sites
Thommo 1217 Posted October 17, 2014 TA02T is definitely 255mm as per the Tamiya website. I have 2 of them and have checked. Share this post Link to post Share on other sites
The Knight 51 Posted October 18, 2014 TA02T is definitely 255mm as per the Tamiya website. I have 2 of them and have checked.do you can swap rear arms? Do you have ff01 to test to get 245mm Share this post Link to post Share on other sites
redzone 212 Posted October 20, 2014 TA02T is definitely 255mm as per the Tamiya website. I have 2 of them and have checked. This confuses me, the ta02 has a shorter tub than a ta01, I thought by 10mm? This is why the ta02 has swept back arms? My ta02sw taisan porsche has 237mm wheelbase with flipped ta01 rear arms...

dutch_rc 71 Posted October 20, 2014 I think the logic is the other way around, the chassis is shorter because they used the swept back rear arms (better motor cooling and center of rotation). It's definitely more than 10mm (although on second thought maybe not quite 20mm like I stated earlier). I don't think the rear arms on a TA02SW are flipped but regular TA01 assembly...

Thommo 1217 Posted October 20, 2014 The difference between the two chassis tubs is 20mm. The TA02T uses TA01 front and rear arms and the TA02 tub. Share this post Link to post Share on other sites
The Knight 51 Posted October 20, 2014 I will try it using FF01 arms front and rear combinated with F150 chassis. upper arms ta02/01 below FF01 Share this post Link to post Share on other sites
dutch_rc 71 Posted October 20, 2014 Looking at the manuals, I would think the gap to mount the rear arms is too wide. But if it's not a whole lot, you may be able to use spacers. Another idea could be FF01 front arms and TA01 rear arms - it looks like the FF parts will make the wheelbase slightly longer. Share this post Link to post Share on other sites

dutch_rc 71 Posted October 22, 2014 Theoretical to me, but looks the same... Share this post Link to post Share on other sites
redzone 212 Posted October 23, 2014 Well ****** me, there you go! I didn't have a ta01 to compare it to, I always thought the rear arms were flipped ta01. That explains why the ta02sw wheelbase is 237 & normal ta02 is 257, due to the ta02 tub being 20mm shorter than the ta01. The ta02t must be the one with flipped ta01 rear arms? I've only ever had ta02sw, ta02w and normal ta02. Share this post Link to post Share on other sites
dutch_rc 71 Posted October 24, 2014 It looks like indeed the TA02T uses flipped TA01 rear arms (that I did not realise). Once again scouring the manuals, this seems to make a 15mm difference in wheelbase. So compared to a TA01, the wheelbase will be 15mm longer but when put on a TA02 it will be 5mm shorter. The dogbones pointing forward on a TA01 does look a bit odd but I guess that's where they ended up getting the right wheelbase with the Manta Ray as a starting point. And probably one of the reasons why the TA02 was designed differently. Share this post Link to post Share on other sites
redzone 212 Posted October 24, 2014 Yeah they angle rearward on a normal TA02. They designed the shorter tub & swept back arms of the 02 to bring the weight distribution further forward to try & dial out some of the understeer inherent in the TA01. Share this post Link to post Share on other sites
