Status: offline 		yeah its pretty bad out here.

tommy i thought about the antirust spray, never tried it, is it an oil or like a lacquer that drys into a layer? if it's an oil, won't it attract dirt?

keep me posted on how it works out for u...

in the meantime i'm hitting the track tomorrow at about 6pm to try out the new engine i bought (after my GXR sucked dirt )...i got an OS 28XZ...I know "it's too much" n "a race .21 is probably faster" etc. etc., but i got it for a good price n i simply couldn't resist the 3.31hp . In addition, i went to the Inferno GT forums, n several people have that engine in their cars without any problems at all. Anyways, if the gears n diffs go, i'll just order new ones, their price isn't too much. And if it isn't competitve on the track i'll just drop it in my Inferno GT.
Just finished heat cycling n the engine is a beast, but i need to get to the track to be able to measure its performance. So far, i'm running it with all the shims (3) and the small 8mm carb restrictor and a crap pipe, with a 15/48 cb/spur.

Should be fun

Status: offline 		Jerzferno - I remember a while back you were saying that you ground something on your front end to get more steering?

Well, last night I was doing some work to the car and I noticed that what is limiting my steering travel the most is when I steer right, the bolt on the steering linkage touches the steering plate (flat thing with threee holes at each end that the steering rods are attached to for each wheel). That plate already has a little arch shape where the bolt goes to give it a little more clearance, but it does limit the steering quite a bit.

What are your thoughts? Should I pull out the dremel?

I sliced off the steering stops on the bottom of the C Hubs. Youll see little squares of plastic that hit the steering knuckle arms. I too noticed the Ackerman arm was hitting. I played around with the steering arm adjustments until I got full throw left and right. Once I got that, then I sliced off the steering stops to get even more throw. I believe I have the steering links in the outer most, hole? Or the rear most hole on the ackerman arm. if you change your ackerman arm position, you'll have to realign the front tires. You should be able to make adjustments to your steering to get the most out of it before going to the dremel. I have done it. I think I have the tightest steering buggy at my track. Let me know if you need more info?

Thanks for the info, at the moment the steering linkage touching the steering plate is what is limiting my steering the most - well to the right at least.
I will do as you say and then look at the hub-mods you mention. At the moment the steering plate is limiting my steering heaps and if I can solve that I will get heaps more steering before the hubs will touch.

Status: offline 		I recently "unretired" the MP7.5 US Sport for my dad. I got him a GO .21 Sport motor, 20deg C Hubs and arms, upgraded the diffs by adding the set of planetary gears, installed new rubber bearings all around, and rebuilt the shocks. I have a Turmoil Pro that I've been racing with the last few months, but I think he got the better end of the deal. Even with only the rear brace and stock chassis, his buggy flexes a bit less than mine (with dual braces and 7075 aluminum).

gbasil77 - The 20deg hubs do not have that bit of plastic that limits your steering. I ran it around my dads backyard yesterday and it's night-and-day different. You could also just dremel out the stock 17deg ones, but there is one advantage to the optional ones you can't dremel: the 20deg ones come with a shield that blocks dirt from getting into the steering knuckle.

Status: offline 		Thanks for the info. I am already running those hubs so yep nothing to dremel there.

My problem was that when I bolted the steering linkage (from the servo) to the servo-saver arm I put a nut on the bottom which was touching the steering plate. I fixed that and gained heaps of steering turn.
Then I was limited by the top-arm hinge pin (captured with nut near there on full right). So I flipped that around and gained even more on the steering again.

I was having so much fun, that I then switched over to my electric 1/10 buggy and noticed that I only had about 30% steering one-way compared to the other way. Fixed that too.

It's amazing what you can accomplish when it is raining and you can't do anything outside

Status: offline 		Nice job GB. Watch out that first time you drive it now.Trust me its like a totally different buggy. Once you get the hang of the added steering, you will be AMAZED that you can turn that thing ANYWHERE. Tight too. It makes a huge difference on the track. Nice job.
Remember I was plannig on making my own bodies? Im about 95% complete with my mold. Just have to do a little bit of smoothing/sanding then Ill try to vacuum form a few. I have a dead line so the heat is on. On September 6th and 7th my club has our annual Challenge weekend race. So I want to have the body ready by then. Here are some pics. The main difference to the typical body you can plainly see is the rear. I widened the rear so the suspension is completely protected. So no dirt and fuel/oil build up on the rear end, no more shock covers, no more piston covers, or lexan plates bolted on to the suspension arms. I also concaved the rear window to allow more air flow over the cooling head. The front hood is a little steeper too. The front nose piece will also be removed from the body and bolted to the front. This will allow easy body removal and installation. I always break the nose piece off over time wrestling it over and around the shock tower.

I like the idea with the rear-end and also the seperate nose.
It looks like a fun project too.

Status: offline 		LOL - The easy parts are done. The mold, the lexan frame to hold it while heating and pulling it down over the mold, and the platen (board which the mold sits on and the vacuum is attached to underneath. Now I have to successfully vacuum form it. That in itself will be a challenge. I have to heat the lexan up to the right temp and consistency. Too hot, and there will be a pile of lexan on the bottom of the oven. Too cool and it wont stretch over the mold. I also need to watch out for tears and blowouts. I dont have any sharp edges that will pierce the lexan. But there may be an area where the lexan stretches too much and blows out. That would be in the rear of the mold. If it does blow out there, hopefull it will below the cut out line. I will only need about 1/4" from the top down for rigidity. The rest will be cut away to fit over the rear of the car. Well by the sound of that last crack of thunder, I better get off now. There was a tornado warning about 2 hours ago. A confirmed tornado on the ground a few towns to the east of me. We have been getting severe thunder storm warnings for the last 3 hours. This is the third one so far. See ya later.
