Shaker - I have good luck with Honda Bond , or Yamaha Bond. It only takes a thin coat. I put it on both sides (very thin) of the cylinder gasket.

I said to myself I see Chip over on this thread and said Chip is Next!!!
Gilly is correct, Mine will be the Pro1. Chip they are all decent cars. I like some features on all the cars. The Cat 5 really was my first choice. I like the way frt end can be adjusted. I like the rear of chassis better angled up.Like the laydown motor. But NitroWolfe had said no advantage noticed with that. But I talked to Jim at PRO1 and they are making a bracket to make theres a laydown as well.And really like the new Pro 1 overall.I wish i had 1 of each. But that won't happen.
GILYHANTREE, we have enough for a Novice class. we can see who gets the Rookie of the year. I know Novice would get to ya.LMAO. :p
Gily Think about the Load that is getting put on those servos compared to a 1/10. OVER 10 time's the car wheight. :rolleyes:i can see the torque being weak but speed i am still puzzled why it would need t be slower. i am headed to cullman to get a couple of servos now.

Gily,

I may hate misled you on the servo speed. It's not that you will need a slower set of servos, just that the speed is not the greatest factor in the steering. I'll ask Allen to elaborate a little more on steering setup in an email and I will post it here. :)

i ended up getting jr servos. st125mg that was about the choices specs at 6volts are .17 speed and 142torque. we will see how that holds up and going to run futaba 9550 on throttle servo.

Shaker. You can always try to tighten first. Be sure to pressure test it for leaks afterwards. any leak causes erratic and inconsistant running. as well as a lean condition.

This may be the wrong topic but here we go. Is there any advantage to running 2 small servos in the steering verses 1 large servo with the same torque as 2 small ones??

Tim Mc
12-25-2006, 12:36 AM
Sprint,

I think the advantage would be servo failure. One fails, the other would probably save the car?! The Mfgs used two during early years just to have enough torque. I don't know if the larger servos were available or affordable in the early years? Someone racing 1/4 cars back in the day would have to lend more insight there.

The Grahm Cracker car runs two large servos at the steering. :)

A racer come up with a bell-crank style steering a few years ago. It used one servo and only needed a 1/3 of the normal torque.

Tim

I had one, the problem is, with one servo you only have one servo saver, which is not strong enough.

I could definitly go for servo saver not strong enough. 1 would think with the servo bellcrank system used on most 1/8 scale offroad would be the ticket. You know they take a lickin and keep on tickin.

Jamie,

Great explanation! I'm glad we have racers willing to lend good/helpful information to us.

Keep it coming!


Slider, by runing the left rear trailing arm up hill , lets say 3 degrees(higher at chassis mounting point) and the right rear trailing arm , lets say 1 degree .it adds rear steer to the car as it travels (when car squats) its hard to explian but the trailing arm is a strait line till it becomes in motion then it becomes a Arc, as the arm travels in its arc motion it begins to move the rear axel longer , if its at a up hill angle to start with, level being its longest point, as it moves upward in its travel( car squating) axel end of trailing arm moving upward , lets say your car squats 3/8 of a inch when you get on the gas off the turn, the left rear becomes level at this point moving the left rear tire backwards maybe 1/16 of a inch, and the right rear was set at 1 degree so at 3/8 inch of squat the right rear trailing arm goes past level(its longest point in its arc is level) it pulls the right rear foward in its motion therefore it steers the rear of the car to a tight off condition right rear leading = tight.

Sorry, I posted this in the LPR forum also...just wanted to make sure everyone saw it.

Hey guys, just wanted to introduce myself. My name is Brian Baker. I am an ex Hobby Shop owner(closed due to family medical reasons), and have raced 1/10th, and 1/8th scale for roughly 20 years. I got out of racing due to the growing number of immature kids that liked to talk smack or protest just because they didn't win............Well let me tell you......I attended the race at LPR a few weeks ago with my father with the intentions on gaining info on the "local" 1/4 scale scene and we can sum it up in just 3 words......"WE ARE SOLD". 3 days after the event I ordered a new Pro1 car and my father is looking at a used 05 chassis...and if not ...he will get a new one too. We were so impressed as to the friendliness and sportsmanship of ALL the racers that it brought back so many memories of the old days that we just couldn't resist. We met Will, with his new to him, but used WCM, Allen, the guy who sold me on the Pro1, Marlin, the man who introduced us to Allen and ran the races, Alex, smooth with the 1/10th scale and others. We are so excited to be getting back into racing. We have looked long and hard to find such a place and feel extremely lucky to have found it and call it our home track. Sorry Tim, from what I understand, you are "the man" there but did not have the pleasure of meeting you.

I have alot of experence when it comes to R/C racing but I realize that, that experience does not contribute much to 1/4 scales. We are really looking foward to meeting EVERYONE involved in the 1/4 racing scene and plan on us bringing at least 1, if not 2 more cars next season!....Brian

Welcome Brian. I think that is how I got started too. The people in 1/4 scale have a much better handle on what racing is all about. It's a lot closer to racing big cars than even I thought. 1/10th and 1/12th was fun back 20 years ago, but it has gotten out of hand.

The brushless stock in 1/10 in the winter is fun. It's great not having to mess with the motor or batteries, but I'm way more involved with 1/4 scale now. More fun, and it is a growing hobby.

Thanks JBell31 for the welcome...I feel blessed to be a part of such a wonderful group of people. That is EXTERMELY hard to find these days. I remember a guy named Danny Roder...raced 1/4 scale a long time ago in Florida when I was about 12 or 13. I noticed a big difference in attitude then. He was the one who would go around helping me and everyone else who needed it. I am sure you guys have heard of Mike Boyln, the guy who started the Snowbird Nats. I grew up racing with him and Ken Holmes,...the organizier of the event. They make it fun..and have been looking for a place like it since, until now.....PS....I found it!

A little update...as of an hour ago....my father just sealed the deal on the 05 Pro1 chassis...so there will be 2 new 1/4 scale cup cars out there next year!.... Looking foward to seeing everyone on the track!.....Brian

Brian welcome.

We must have been racing around Florida at about the same time. I knew Danny Roder. He use to come into Phil's Hobby Shop up in Pinalles Park, (I worked for Phil in the Bradenton store.)
Only ran at Fast Tracks a few times but use to run dirt up in Gibsonton and at the Sidewinders Club track in Palmetto. Also ran pan cars all over central Florida.

I still talk or e-mail with Boylan pretty frequently.

I've been away from the 1/4 scale world for a few years but really looking forward to coming back this season.

LPR is one of my favorite tracks. If I can help with anything let me know.

I really miss FastTracks!....I used to ride up to the McDonalds on the lawn mower that he packed the track with!...LOL (Thanks JIM) Florida State Champs, Jimmy Shea, Case Fessler, Paul Schuab( not sure on the spelling)...the old school crowd. That was what I was reffering to. I remember going into Phil's and DROOLING over the Purple 1/4 scale sprint car they had sitting on the counter. Nice to see you around. Hit me up in an e-mail.....Would love to chat about the old days!.....Brian

Another ? Is the Futaba S-5301 to overkill of a servo for throttle and brake. Or what servo is most of ya'll using.

DCLARK
01-03-2007, 08:39 PM
No it is not overkill, I and a few other guys here at Easley use Hitec because just cheaper than Futaba and have good luck with them. My throttle is a HS-705MG. And HS-6545MG's on the steering. the 6545 is and older servo but same as HS-645MG. Just something to think about because you can buy 2 say HS-705',s for one Futaba S-5301. Hope this helps some.

Putting it on Pro 1. It has 1/4 scale aluminum mount. The reason i ask is I have a 1/4 scale futaba FP- S134 in it now,the specs i found at futaba doen't tell me the torque if it is at 4.8 or 6.0 volt.it is a older servo and it does not want to pull the throttle very good.Made a new throttle cable today. no help. carb turns smooth. a tad stiffer than i would like but that is in the spring.

Check for the cable binding also. Where the cable leaves the liner, be sure the path to carb or servo is true. If the cable is rubbing the side of the collar, this could over work a servo.

NitroWolf. From that post on Cat 5. I do not feel you are the one that needs to do the follow up on it. You are the purchaser, the man who builds and sells should be following up on his transaction as he had stated a date would be sent on delivery. That is poor buisness on his end.And i don't care how nice a fella he may be.Your word is your word. Hold true to it. But congrates on your new ride. Hope all works out okay.

Slider, if I use the logic you are using in your post, then the buyer is completely without any responsibility in the transaction. I don't think that is right or logical.

Let's say it is any one of the quarter scale manufacturers out there. In this case, the online purchasing is set-up with an automated email response when a purchase is made. If for some reason there is a glitch or a hiccup in the process, how would the manufacturer ever know if no says anything?

If the manufactuerer doesn't know that he has a problem with his automated selling system, how in the world could he even fix it or make it right with a buyer?

In addition to the follow-through concept, bringing up a beef in a public forum without at least offering the person or persons in question at least ONE opportunity to make things right is contentious at the very least. ***I don't believe this is what NitroWolf did; he just asked a question; he didn't rant about the manufacturer.***

There is not one of us that is perfect and no system is perfect; again regardless of the manufacturer.

Regardless of whether it's Scott or any other manufactuer, I think a person has to offer the other party at least an opportunity to defend himself or make things right. Think about it, wouldn't you want the same opportunity if someone was accusing you of wrong-doing or mistreatment?

Slider
01-21-2007, 11:48 AM
Okay then it kinda goes with this. A person buys parts online. it states all items are shipped by UPS. Fine you give them the address that it will arrive at with no problem.since UPS don't deliver to PO BOX. But then after it is shipped he sends a responce back saying all items on the way shipped via USPS. well guess what they get sent back because invalid address. So who is at fault? the purchaser?I don't think so. I get sick and tired of the way alot of these transations online are handled.

Tim Mc
01-21-2007, 12:07 PM
My question was of curiousity. I've never purchased from them so I did not know what to expect. I do understand that this is the busiest time of the season for the Mfgs. My remark of "not being impressed" is/was towards the follow up email of shipping date which was stated to happen.

That night I placed three orders from three different suppliers. All were ground/standard shipping. I received confirmations of all three orders. One order arrived Wed and another Thurs. To me this is as fair of service one can expect to receive. :thumbsup:

I'm not here to slam any Mfg. Just needed a vote of confidence for them. :)

So, with that said I will continue wait for my carb and other parts ordered (not a new car)........yet!

Hello
I would like to thank everyone for such a cool sport & the help I've gotten so far. Purchased a great used car with set up instructions, got excellent advise on parts, what to get for tools & set-up tools. I couldn't have asked for better treatment, thanks again.

My first set of questions on here is what radio seems to be the best for the money? I've decided on the Futaba 3PKS with the 2.4ghz module. With this set up will I need a transponder or does this radio keep track of this? It's probably in the instuctions, but I have not read anything about this feature. I have not bought it yet, still hesitant on witch one. The Nomadio React seems to be a hot item, but how user friendly is it? Any help here would be great.

The car I purchased is a WCM. These things are amazing, I have not been around rc racing for about 15 yrs. & I'm glad to have found this.

Thank you again for the help, & to Dave D, Orrin, Brett & all the Randy's.

I and my racing partner have purchased cars and a Lot of other parts from Scott. I have yet to have a problem with getting my order in a timely manner or problems with follow ups. That was the main reason I bought a car from Scott. I had a brand new "other Manuf."car This year, I made a few calls and could'nt even get an answer or a call back from them. Another Manuf. that my buddy was using took almost two weeks to send out a part. He ordered the part the monday after the races, he got the part 12 days later. I dont think I have ever waited more than three days for parts from Scott. As far as I'm concerned Scott was what some of us needed in this hobby. Something different. You can actully get an answer when you call him. You can buy parts online at three in the morning if you want to where else can you do that.

Thats just like Jamie building the GN ans sprint car, We need new people doing things in 1/4 scales. The cars have basically been unchanged for how long? That is not good for growth. We need differences in cars. I can't wait for Jamies cars to be finished. I'm going to get one of each if I can.
