The OS .30... is it a decent mill?

[jon2]

Cool, so you are going to get the OS .30? Are you going to go with the pullstart, or non pull? I am looking hard in that direction, but am still on the fence. I just bought the CRT X1 kit and the electronics, so the mill will have to wait a bit. What MT are you going to put the .30 in? Take care.

Tom

Yes I am going with it and I want to use the Spinstart still as I really don't mind anymore. I just need to take more care on how I use it and clean it regularly. It will be going in the LST I have now. I am pretty happy with it so far as what it has but I will be upgrading still..

 

[godale03]

Cool, you will have to keep me posted as to how you like it. The LST is a great truck. Hey Jon, what is a spinstart? Thanks for all the info.

Tom

 

[jon2]

Spin Start.. A better version of a "rotostart" IMO

 

[godale03]

Oh.. ok cool. Do you have to fit a different back plate on the OS in place of a pull start? Sorry for the dumb questions... just a bit curious. I am not a huge roto start fan... I have seen folks at the track have problems with them. I am interested to see if this is something that would work for me. Thanks Jon.

Tom,

Horizon Hobby/ Losi has come out with a Spin Start conversions for some mills. Check them out at Horizon Hobby. I think they are way better than the HPI. I have both and like the spin start. Also you can use a regular drill to use if your spinstart battery dies whereas the HPI one I have never gotten my drill to turn my Savage over.

Not too sure if you just remove the pullstart and put the plate but I am sure it runs along the same as the HPI conversion.

Thanks Jon, I will do that. I appreciate the help.

Hey godale, do you only race at one track? I was just reading on another forum for a track that uses ROAR rules that the .30 is not allowed and they don't believe they will change the .28 limitation to include it. This came right from the chairman's mouth for the Fuel Committee. There was a guy who bought one planning to run it in one of the big races coming up and he asked the question and they told him no. Anyway, I know most local tracks are a "run what ya brung" so you'd be alright and as a basher your fine there, just thought I would throw that out there for you to think about.

Thanks for the info. That is very interesting. I was under the impression that the .30 would be allowed in the Unlimited MT class. I have never run at a ROAR sponsored event. In fact I am not even sure if there is a ROAR race in MD for that matter. That kind of stinks too. I was hoping that maybe once my skills improved I would go looking for one. Anyway, I usually only run at one track and it is like you were saying.. "race what you've got" but I am still looking into other mills just in case. That is very interesting news about the .30. Thank you my friend for the info. Definitely food for thought.

n/p the guy that was asking originally on the other place was pretty bummed about it though he had other mills to run, just didn't want to see someone here get caught up in the same snafu.

The two tracks I have visited out here run ROAR regs. One of the reasons I went with the RB 323 for my Revo. They both offered an unlimited MT class, but only as a sportsman class. If you get too good, they put you in a little book and will not let you enter another sportsman race again.

 

[jetmechG550]

Nice, I think ROAR is redoing how they classify trucks in class. I'll have to go and re-read the thread again but there was mention of it cause all this track is running is 1/10th (2wd stadium trucks), 1/8th buggy and Unlimited Monster Truck and all the Revo and Savage guys were like WTF? The damn thread is over 20 pages, it might take a little time to find again.

 

[godale03]

Don't you hate that? I have never personally had to deal with that, but I have heard of others that drive at my local track complain about it. I guess I can see ROAR's point. They want to keep things fair, but I still think they should not kick you out of a class that you may want to stay at. Not everybody desires to make it big. Just my

Anywho... back to the thread. I have read that the .30 has a bum rear main bearing? Has anybody else heard about this? I also run on a very short track with alot of hills and jumps and only one long straight... well it is about 20 yards long. I think as far as I go the .30 would be great paired with the JP1. My track rewards low end grunt more than flat out top speed. In fact even if I were to travel to the next closest track, it is still a small one. Just a little bit of background as to where I will be running this truck primarialy. That is why I think the mill would be ok, at least for my use. Thanks

P5....better fuel economy and you won't ever have to deal w/ the ROAR issue of it being legal...you also KNOW it's proven.....I'd say 421b but those are higher price......and a lil bit tighter "sweet spot" for the tuning......

How would I break in a P5 if I don't have a drill press? At least that is how jon2 said he broke his in. Also, when they talk about break in processes... what does it mean to use the heat cycle method of breaking in a mill? Thanks

Didn't you break in th eRG you got??
How did you do it?
the drill press is the rare occasion in breakin.....you can do it on a regular bump box...just have to be more precise.....if it's too tight just remove the glowplug/dump ARO down there and turn it over for about 30 seconds...put plug back in and fire it up........always worked for me.....
heat cycling is when you run the mill for a while to get teh temps up over 200 under 220 and then shut it down....let it cool w/ piston at BDC.....start it up and do it again....this should be the first 5-6 tanks...basically you are heating and cooling th esleeve similar to how you harden metal )heat and dip it in water, the metal gets a hard "shell" on it....more rigid and stronger.....in these engines the idea is to "mate" the Piston and sleeve...meaning ANY imperfections made during manufacturing (small burs and nicks in the metals) will be worn away and the metals will fit together like a puzzle......and create a good seal.....how to heat cycle your mill is debateable..I do it on a stand at Full throttle........most do it in the car and just drive it easy to bring temps up......

I broke in the RG ok. I was just curious as to what the term Heat Cycle meant is all... I was wondering if there was an easier way to break in a mill is all. I was also curious as to how the drill press worked as far as breaking in. I just thought the P5 was a bit harder to break in. Sorry if I sound like an idiot. I am still new to the engine break in deal. Thanks for the info.

I am curious as to if ROAR will allow the .30 for next year? I wasn't clear as to if the ROAR guy was saying no you can't run the .30 this year, or no, the .30 will not be ROAR legal next year? I kinda agree with the fact that O.S. probably didn't make that mill just to bash with. I guess we shall see. Thanks for the info.

I took his comment "don't count on it" as being they don't have plans to bump it any time soon. Seems as though they aren't going to ammend the rule or make exceptions for one engine manufacturer. Though I think Trinity has a .30 coming out or it's already out.

 

[godale03]

You Know I have read that somewhere too... I will check to see if it was in one of my XRC mags.... ROAR is a pain in the but anywho. They fail to grow as fast as the sport of RC racing has. They are at least 2 years behind the technology. They are still giving brushless motor folks a fit! Oh well, maybe O.S. and trinity will step up the pressure. ROAR has an unlimited MT class but as far as the ROAR rules go the are indeed limited. The more and more folks that go the the truggy MT class running bigger mills, ROAR has to break eventually or they will have everyone running in the sportsman class! LOL
