Had a good day today with the aero, i seem to have ironed out a lot of the small issues:thumbsup:

I did 3 runs before it snowed and finished them all, so reliability is ok:thumbsup:


The car had masses of steering but was also very predictable, i used a diff, usually im a 1 way man but i felt the diff was easy to drive and the brakes were good for the short blasts between corners on todays track.

Here is my setup from today, any questions please ask.

Attachment 2521

Lee, good skills with the setup sheet:thumbsup:

You refer to losi piston number, are you runing the losi piston or re-drilling the Aero pistons??

I watched your car in your last run and it's starting to look like a serious contender....

JIm:p

:woot: Cheers jim, its getting there:thumbsup:

The pistons are aero ones drilled to various sizes, losi and ae pistons are a slightly smaller diameter so the oil goes down the outside instead of through the holes:thumbdown:

There is a few more things i want to try but i am confident i can turn up at kiddy now and the car will be pretty good:thumbsup:

Hi Lee,

Are you cutting any spikes off the tires (outside edge) or running them as standard? If as standard are you getting any grip roll?

I have the inside and outside rows cut off the front, the rears are full.

I experienced some grip roll yesterday on the banking at bury but i think this was because the back end was a bit high. I was also going to take the outer row off the rear if lowering the rear didnt help.

Cheers Lee, my tranny module arrived today so fingers crossed if the rear wishbones make it by the end of the week, I'll give it its first run on Sunday in the MW regional, in prep for Kiddy nat!

Dave what is wrong wit the wishbones in the kit?:confused:

Just want to wait for the stronger ones to arrive, I'm worried that if the kit ones fail it may break other parts from dragging them along?

Are the kit ones not actually too bad then? I was about to bin the front ones, wheels too!?

How long have you been building this thing? I thought you bought cars to run them and not to obsess about the build :woot:

No offense meant!

If you want you can fit TRF501x or Durga front arms as well. You have to dremel them a bit but they are STRONG and fit well with a bit of work.

And then get out and run it :thumbsup:

Rear arms arent too bad dave i took one out from landing off the side of the table top at the IF`s. I think any wishbone would of snapped actually.

Wheels will be ok when its a bit warmer, its running them in freezing temps that causes them to crack, but aero are rectifying this. I used my aero wheels for worksop, they were fine.

Also when the wishbones break they dont bend anything:thumbsup:

The stronger ones might though:lol:

Might be worth looking at D4 front wishbones? They are metric too :confused:

G

No offense taken, but I couldn't fit my existing electrics in, or the first thing I bought to replace them, so there's been no point rushing building it when I can't then run it anyway!

All my build questions are because I've only ever built Tamiya TRF's (501 and tourers) before so have never built shaft drive and am used to the most detailed instructions ever!! I'm rubbish at guessing this stuff and my kits go a LONG time between rebuilds, so really want to get it right first time! So apologies for boring you all with dumbass questions! :thumbsup:

dave
you should have your spares tomorrow,kit wishbones are brittle, the glass content was not right, the replacements are not stronger they just have a different composition to make them less brittle. two aeros running at stotfold yesterday and no problems with the replacement parts.
john

Is this spares kit coming to everyone automatically or do we have to request it?

Whats the new spring sets equivelent too?

http://theraceplace.co.uk/oscommerce...roducts_id=336

(in Losi colour terms??)

not sure stu but i think they are all softer than losi green, i am waiting for the rates from aero

Thats great thanks John! Its really nice how hard Aero have worked on improving the few weak points, think about other cars that have been released with issues and they rarely fix them this quick!

The new wishbones look and feel so much better than the old ones! Nice amount of flex without being too much and way more solid than the first ones.

the Front caster block are 6° or 4°???

Do the instructions get them the right way round by the way? Mine add to the castor of the wishbones themselves, but the driveshafts rub them on full lock!

Yes thats right:)

Is it like a handbrke effect on the inside wheel? :confused:

G

To be honest G i didnt notice it till you pointed it out:confused:

I'll get a good idea of if it has any effect this weekend, weather permitting!!

The steering does seem a little different mind, I reach full lock on it with only 50% EPA!!

Dave, there doesnt seem to be much steering lock, but the car has plenty of steering on the track, if you need more though you can always dremel off the bit of hub that hits the castor block. I havent done this but i think kev has. I suppose its there if you need it

Just done the "dirveway" test before its first run tomorrow, its nice and quiet and a rocket in a straight line!! :thumbsup:

Think maybe I should have followed everyones advice on the shock pistons though, looks very bouncy at the back, will play with springs/oil tomorrow!

Has anyone found out the spring rates on the spring sets yet? Also, found any alternative pistons, bit worried about drilling mine without having spares!

Dave,

As a starting point drill your pistons to 57 (black) in the front and 56 (red) in the rear. and run it on 30 wt oil all round with blue springs up front and reds at rear.

you can always go slightly softer later but thats probably a good starting point and is pretty much what i'm running.

I can post my setup here if you are interested but little things are changing all the time at the moment.

If you are using losi pistons, take them out, you'll find very little difference between the different hole sizes because the oil is going round the edge of the piston (they are slighly smaller even if they do look close)

Cheers Kev, I don't follow the drilling bit though, is that sizes of hole your suggesting (57 etc)?


Would be great to see your setup, though maybe your right in that its best to wait until its settled first, I may pop over at Kiddy to ask where your ending up on setup though if thats ok? :thumbsup:

Dave, the drill sizes kev is referring too are an imperial size, 57, 56, 55 and 54, these are the size of the holes in the losi pistons 57 being the smallest hole (black) and 54 being the biggest (Blue)

last weekend i ended up epoxying the holes i had drilled in a piston and drilling some more:thumbsup:, im 56 in the front and 556 in the rear. i have made a few changes to my car for tomorrow, so i shall be trying how kev ran his last weekend, i was quite close anyway but i used a losi front spring and was 5 wt thicker in the front.

If you are racing at southport tomorrow come over, your welcome to have a good look at the car and pick my brains.


Off topic but has anyone received the new plastic replacement bits yet?

northy sells the drill bit sets
lee did you look in to having them made from ptf
I'm sure some nice man with a lathe will oblige

I am carl the ptfe bar is peanuts, i just need to get a nice man with a lathe now:lol:

Cheers Lee, I'm at Ledbury tomorrow, at least until the rain comes!! Are you at Kiddy next week?

By the way, I have no scales at home, I assume it doesn;t come in underweight, I've never see a 4wd even close?

Oh, and no, haven't had the plastic bits yet! Think they may still be working on the wheels though, and I guess they'll want to send it all at once!

No probs dave, ill be there next week, the car is feeling good now, im sure you will be very impressed:thumbsup:

Certainly liked it just mucking about today, felt very "sharp" I guess is the best word!

I think your questions have been answered on the drill sizes. I will post my setup after tomorrow on what i plan to start with next week.

You are more than welcome to come and have a chat next week (i'll be pitting near the raceplace shop). Bob an Kim are planning on being there so you'll be able to have a chat with them too.

Sorry guys, do you mean 57 is 0.057" drill bit?

Ran it today, and sadly struggled a little, defintiely with running stock pistons!! Got a bit better when I put my tamiya dampers on it (I don't have the correct drill sizes) although it still didn't like jumps!!


Reasonably happy though, it was similar speed to the 501x I run by the end of the day, not a mile off anyway, and I think will get better once I get the dampers sorted! :thumbsup:

While on shocks, are you guys using extra washers to remove the play in the piston between the c clips? My pistons wobble but not sure if thats bad!?

Dave, i did try a washer in between the piston and the clip, i didnt notice any difference to be honest when i did.

With regards to drill sizes its not as straight forward as you think but here they are

#57 = .043"
#56 = .0465"
#55 = .052"
#54 = .055"

If you want some for kiddy, i can get you some, i have to go to the shop anyway.

I ran mine again yesterday, it felt pretty good again but i was on BB greens as it was a bit damp, i only used it for 2 runs and when the track dried i got the B4 out to give it a run for kiddy.

That'd be great thanks Lee! Any idea what the standard diameter is, is it less than 1mm?

i didnt measure it but i would guess its equivelant to a losi natural which is .0400"/ 1.00mm

Ill pick some up on the way home on friday:thumbsup:
