Hey guys this is a good discussion lets keep it going! Again we chose to run the car in the offset position because for my son's driving style and the tracks we run at the car in the centered position was just too aggressive for him and he wasn't comfortable with it. I think its a matter of choice and what you are comfortable with, not all setups suit everyone. We also run the short wheelbase with the offset.
01-28-2003, 09:55 AM
That post absolutely rocks!! FINALLY !!! a good explanation of it.
01-28-2003, 10:01 AM
Short wheelbase, huh ? hmmmmm...
There is an Associated sponsored guy over at Trackside -- they are telling him to run the car with as long a wheelbase as he can to make the car faster through the corner.
01-28-2003, 11:09 AM
When I said the car was too agressive I guess I should have said that we want the car as agressive as possible on entry and to achieve this with the 700 it made it turn too much on exit (driver didn't like this) To correct this we would have had to given up something on entrance ie. stiffer RF spring, harder RF tire which would have hurt the entry. So what worked for us was the offset pod which didn't really affect turn in for us. If that makes any sense we wanted it to turn in very hard but needed something to drive it up out of the turn besides a ton of tweak.IMHO on flat tracks you need to turn in as hard as possible.

Mike -- I agree.
On my 700, I'm running the LF in the middle offset position, and the RF all the way in. It really turns in well. Where are you running the front end ?
01-28-2003, 11:18 AM
We were running the same setup in the front as you but then tried a couple of spacers behind LF wheel to move it out and son liked it even more so now we run LF all the way out and RF all the way in.
01-28-2003, 11:19 AM
Cool.. I should try that.
What are you running for shock oil/springs ? I'm at:
Center: 50 wt, silver spring
Sides: 30 wt, blue springs
01-28-2003, 11:21 AM
same oils and springs, sometimes a green in center if not enough bite
01-28-2003, 11:22 AM
Wow.. scary how similar the cars are. T-plate ? I'm running the stock graphite one. Was considering trying a TRC spring steel.
In the front I've got green Wolfe standard springs L and R.
01-28-2003, 11:24 AM
T-plate is the stiffest one with an oval slot in it. I think there are three of these and a solid one from H.D.
01-28-2003, 11:42 AM
what does moving the left and right out do to the car? my car turns hard get the rear loose going in then some times it seem like it really turns hard in the middle and might lift the lft front or roll over or darts to the lft coming out. you can also hear it bog the motor down coming off the corner.
01-28-2003, 11:46 AM
Sounds like tire/spring issue. I run black fronts (sometimes grey LF) and green springs in front. I had a red RF spring, but the car seemed to be working against itself in the middle -- sames as you -- heard the motor bog down in the middle of the corner. Seems much better with the stiffer green RF spring.
01-28-2003, 11:46 AM
for us moving LF out made the car turn in harder and moving RF out seemed to tighten it up on exit
01-28-2003, 12:01 PM
i think that tires or some of my problem plus i am a
concrete racer trying to learn carpet lol . what do u guys
true your tires to i have heard not to go smaller than 2.20
and not larger than 2.3.
01-28-2003, 12:39 PM
2.230-2.250 to start and for weekly show we run them down to 2.130 but they give up a little performance by then.
01-28-2003, 01:47 PM
Mike M's set up really drives hard in and just holds it's line as far as you want without bogging the car down. The first time I drove his car I said it drove off the corner like it had 6 cells. It didn't, I checked. It is very aggressive without being unstable or unpredictable.
01-28-2003, 02:13 PM
I wonder how much that stiff t-plate has to do with that. I'm running the stock graphite t-plate that came with the car (is that the softest one or the medium?). He's running the stiffest one with the oval cutout in it.
01-28-2003, 02:22 PM
Medium comes in the kit.
01-28-2003, 02:39 PM
what t-plate is MikeM using? does anyone use the t-plate that comes with the car? it seems real stiff. i have seen alot of people using the .63 solid fibreglass t-plate around here.
01-28-2003, 02:42 PM
I run the t-plate that came with the kit. In fact, I'd like to run a STIFFER one.
I run a grey LR and a black RR and the car doesn't even start to get loose.
01-28-2003, 02:43 PM
how much weight are u guys running on the lr?
01-28-2003, 02:44 PM
300 - 310 grams. This is without the offset pod.
01-28-2003, 03:17 PM
Donnie we run the one with the smallest hole (stiffest) one from H.D.
01-28-2003, 03:20 PM
300-310 for us too but that depends on your scales, have seen a wide range of numbers from different scales!
01-28-2003, 07:58 PM
donnie 99 moving the center line of the front wheels left increases steering and moving it right decreases steering.Just the converse is true for the rear axle moving the ceterline right=more steering,left=less steering.
Anybody got a answer to the servo mounting/ackerman question I asked a couple of posts ago?
01-28-2003, 08:30 PM
Yeah -- I mounted mine .850 back from the center of the rear hole of the lower a-arm mount.
This is where Mike Valentine advised to drill. Move it back further for less ackerman.
I've got a template that I'll post too for drilling.
01-28-2003, 11:49 PM
If you offset the rear pod, then you can't move the battery tray all the way back anymore -- is that right ??
I just got the offset top plate -- it looks like offsetting the rear pod moves it over too far for the battery tray to move back as far as it does with the pod centered.
01-28-2003, 11:57 PM
I asked the same question last week. What I found out was that the early kits were shipped with battery trays that would not allow the pod to be offset. They never anticipated anyone wanting or needing to.
That said all the new trays are offset compatible. Call Barry at Hyperdrive or Bruce Triplett at RC 4 Less and they will fix you up. I love mine offset. A monkey could drive it and it's fast.

HYPERDRIVE offers two diff type battery trays, one in which the rear battery is wider allowing the cell to side, and the other designed for the offset pod in which the rear cell doesn't slide aloowing room to offset pod. the kit should come standard pod with the widr rear battery slot.
01-29-2003, 09:35 AM
lately, i have been maxing out the left side weight. i am running the pod offset, 4 cells max to the left and rear on the 6 cell tray, speedo and reciever on the front of the tray, and the LF spaced all the way in, the RF all the way out. after i went from the shortest wheelbase to the medium holes in the front, the car was so much more predictable, that i decided to get more radical w/ the left side percentage. seems to be working, as the car is a bullet through the corner, and more solid than ever coming off. actually, i am doing everything i did when the wheelbase was short, but that one change made the car 1000% more drivable, and no loss in speed.
01-29-2003, 11:14 AM
rcavenger thats the problem with the really short wheelbases, under 10'. there are some people who swear by them. most run 4 cell stock classes where i don't htink the problems show up as much.
01-29-2003, 03:30 PM
well, after i talked to u that one night, i used the setup we talked about, w/ the 10" wheelbase. ever since then, the car has been solid, and i have been able to make the adjustments i want to and get the results i am after. i am convinced now :thumbsup:
Which holes are the 10" wheelbase?
I'm building a 0700 for the fist time.
01-29-2003, 04:00 PM
davz short in the rear and middle in the front
here's all the different wheelbases and there locations
9 5/8 (9.625) front short rear short
9 13/16 (9.8125) front short rear long
10 (10.000) front middle rear short
10 3/16 (10.1875) front middle rear long
10 3/8 (10.375)front long rear short
10 9/16 (10.5625) front long rear long
01-29-2003, 04:01 PM
middle set in the front. not sure which ones for the t-bar mount.
01-29-2003, 04:56 PM
I ran mine short rear middle front with an offset pod last weekend at AJs in 19t and I have to say its the best I have had a car in awhile.
Of course the tire brand switch prolly didnt hurt either.;)
01-29-2003, 05:17 PM
is that the first time u have run that wheelbase, HOOPD1? I know u were talking about running that wheelbase, as opposed to the short wheelbase u have been running. was the car more consistent on corner entrance?
01-29-2003, 07:55 PM
Baroose does that mean you can drive it?LOL
01-29-2003, 08:35 PM
rcavenger,this was only the second time I ran the 700 but it was a whole lot better than a short adrenalyne.
I just decided to get out all my notes from the last few years and the way the 700 ended up was almost identical to my original Gforce from five years ago as far as wheelbase,offset,front track width and left side weight.I shoulda held on to that car :lol:
I ran the six cell tray so I could put the speedo and receiver up front and the battery all the way back.And then I put the transponder where the speedo usually goes on the right.
I also ran the pod offset.
I dont know how the car could have been any better........Im sure it could be but I havnt found where yet.
I had to run 45wt oil in the side shocks to slow down the initial turn in a little or the car rolled over more than I liked and then it was faster in the middle of the corner wich made it faster off.
I ran a gold on the right and a blue on the left with a red center spring and a 063 solid tplate.I tried a spring steel plate first but the rear never really felt planted with that.
Overall I like the car so far and this weekend should be a good test since I think there might be enough guys that want to run mod,screw this 19t crap :lol: Are you and Ron gonna make Vinton sunday?
01-30-2003, 08:43 AM
yup...as long as we don't get a blizzard or somethin:) hopin to turn a bunch of laps. do u know if Danny B is going to be running stock, like last time?
01-30-2003, 08:57 AM
Yeah, Bob, I thought I'd dangle that carrot and see how long it took someone to bite. Good luck with work and enjoy your 0700.
02-08-2003, 09:42 AM
Just thought I would bring this near the top again.
02-09-2003, 01:32 AM
A man walks in to a bar:lol: :D No Barooose i will not go their. Hi Mike how was Thur with the 0700
02-09-2003, 09:45 AM
Hi Dave, Thur. wasn't the best. We tried alot of new things and nothing worked! Bruce had the car to beat he was very fast but had to leave early, wasn't feeling well. Wound up with TQ and win but it was a struggle. Hope we see you some Thur.:)
02-09-2003, 12:27 PM
Anyone using the rear steer for the 700 yet and which one 1/4 or 1/2?
Was wondering how the 0700 ease did at the snowbirds and what the setup was. I just got one of these and I'm wondering if setups are close to what i have.
02-11-2003, 01:39 PM
Eric Anderson was Fast in 19t with his 0700 i think he ended up 2nd

02-12-2003, 11:34 AM
Mike thanks for all the posts. That you have been putting up on hobby talk it has been really big help to the guys in Nebraska. Keep it up!!
How did Hyperdrive run at snowbirds?
It doesn't show the make of car on the www.teamtrinity.com web site.
P.S. Good run at snowbirds
