I'm at the tallest gearing I can purchase, so next is some custom gears.  The boys at work can do that for me but at the moment I have no chance of them completing the job as they have 4 chassis on the go for the start of our season..

supertib

what brand of fuel are you currently running ? your running a 086 pipe ? which glowplug............ answer these 3 questions and maybe I can find you more power...................

ARDV8

If anyone can give you more power Neil can................question is can you handle it lol

ryan_t888

Can anyone confirm the pitch of the spur gears?

Barber420

My Feedback: (1)

32 pitch

ryan_t888

Thanks, I keep getting it confused with Mod1.

Edit: Details in Next Post

ryan_t888

I just ran measurements and did some calcs on the 48t spur, 44t spur, 14t pin, 18t pin, 16t pin, and 20t pin.

They are all coming out to be a 25.4 diametral pitch which is Metric Module 1.

Hi

whipnet

The first upgrade to any DM-1 should be the brakes.

Took my DM-1 with Mach 427/Go 2047 out Saturday last weekend, and it ran great... Took it out again Sunday....................., and it ate the 2nd-gear spur...

This car for me is predominantly a PIA. With zero local or even nation-wide part support.

To think I got it instead of the Kyosho IGT2 - which has abundant local (and CHEAP) part support, because of all the 2-speed issues the Kyosho supposedly had...., is ....................................galling, to say the least...

Just do what I did, get onto Ofnawarehouse.com and order $300 worth of spares, I purchased clutch bells, bearings suspension components, gears, shocker kits etc etc. pain in the arse but it's the only way I could keep it going.

Or do this, buy a Kyosho Evolva and a Capricorn C801, you won't have any money left but heck, that Capricorn C801 is a nice car.

Hey Telvery, so have you been frying gears too?

I'm really kind of in a c.rap situation here with my DM-1.. I basically have two of them, and have invested a couple hundred Euros already just in stupid little clutch and 2-speed bits(and OK an alu chassis brace..) But I can't keep an RC that blows a 2-speed every second time out.. AND with zero European parts support, and $30 clutch bells..

HerrSavage

double-post

ryan_t888

I don't have any issues with the 2 speed spurs and I'm running a lot more power through them than most.

HerrSavage

Last time out I was running buggy onroad tires instead of the smaller diameter rally game tires. So I had to adjust the shift-point. Which I did quickly, and it responded well. The shift was still a bit late, but it sounded cool and was performing great.. Next day though, half-way through the first tank... wwwaaaannnnggghhhh!!!.. Great.. I had VERY carefully shimmed the CB(which is still perfect..) and set what on any other RC would be a good mesh. Does the DM-1 just need a special kind of mesh - loose or tight? And is the 2-speed that sensitive to a slightly late shift point?

ryan_t888

I would have to say no, the 2 speed is built awfully strong and handles shift points at any speed The clutch used is a full surface clutch that is solid in material.

I still have the original spur gears I received used with the kit over a year ago. Never stripped a spur. Never counted the amount of cycles but I would believe I'm well over 50 easily.

What is breaking on your 2-speed assembly and how are you mounting your engine?

supertib

geez..I have 2 DM-1's, we run crazy engines and have yet to have any issue with the clutchbells...heck I have not even heard of my customers having these issues....Must be doing something wrong dude !!!!!! or missing something........ or everyone with these ars would be having the same issues.... Of course unless you got a string of clutch gears that were factory faulty, improper hardening.......... Very common to have bad production runs with Taiwanese products........We are still on the original gears on our cars, from 3 years ago.....so it is definitely possible that the newer batches of gears are too soft.....

whipnet

I've had some small rocks tear up one of my spurs on my DM-1, but that is it. I run brutal brushless power with my 2 speed as well.

I have a ton of experience meshing similar CB/SG setups with my LST2's.. And I've meshed a ton of other RC's over the years. I haven't had SG issues like this since my first RTR Savage 6-7 years ago.. I know how to mesh.

This past weekend I just gunned it, 1st wound up high, then bam... Knew immediately the 2nd gear was gone. Even ran some more gas out of it in 1st.. The 44T gear was just rounded out like you'd see on the old Savage SG's.

I mean, I don't know how you people drive, but I like to drive my RC's pretty much all-out on the gas. I was drifting a little bit, and hammering it out of the curve onto the straight (was doing that when it happened..), but nothing too over the top.

I'm even especially careful with this DM-1 now, since having these issue. The CB was thoroughly cleaned and shimmed, and the mesh was good.

Maybe it's just little rocks?? But man, that's some pretty bad luck.. The track where I run is pavement, with some dirt and pebbles, but no worse than your average parking lot or neighborhood street...

The incredibly frustrating thing is I got this car over the Kyosho IGT2 because everybody said that car had 2-speed issues. And here I can get Kyosho parts local and cheap, and for a stupid Ofna CB or SG I have to order from a different continent... So far my DM-1 has not gone six full tanks without shredding a SG. I think for my next order I will try different gearing and see if that helps. I guess 45-49 on the SG's since 15-19 is too hard to find(for me, from a shop with sensible shipping rates..) for the pinions...

supertib

something has to be wrong

what gear sets are you running ? you must be running the wrong tooth counts...something really simple you are overlooking....

very very few nitros would have the power of your 28.....

HerrSavage

Gearing is bone stock - 16/20 - 44/48.

The only thing I can think of is maybe some kind of chassis flex. This "Sport" kit version is basically the 1/7 RTR version as a kit. It has plastic chassis braces. I put in a Kingz Headz CRT alu one in the rear*, but it' still happening.

* The brace is alu, but the shock holder top-plate thingy is still plastic and flexes..

I can't swing it right now, but eventually I guess I might try an alu front brace and alu shock holders front and rear.. The chassis flex idea is just a theory.. With the lay-down shocks front and rear, and the long chassis, the car does seem to roll around it's longitudinal axis (right term?..) more. With buggy shocks in the rear I can imagine that being reduced(why some people actually mod their 1/7 DM-1's to have stand-up rear shocks... AND fronts even..) Still, I've never heard of 1/7 DM-1 people with issues either, so IDK.. A CRT King Headz engine mount could also be worth a try.. Not going to invest in any of that right now though. It's buggy time....

I was running my LST2 on a track yesterday. Was going great til it made a weird sound and starting only running at low speed, despite high revs. I thought "oh crap, 2-speed..." Took off the gear cover and saw the SG's were in mint condition.. Was a blown rear diff and mangled CB bearings.. Anyway, I was running on a track and putting the truck through it's paces, and the 2-speed was rock solid..

Had some very bad luck with air filters falling off though. Might have cost me not one but two engines...(BOTH zip-tied like always!!.. Has never happened before.. []) Anyway, might have to change my engine constellation and finally get that RB RT10 engine they've been selling cheap here(€99) for the DM-1.., and move the Mach back over to the LST2 - if the Big Red really is toast.. Or, an LRP 30 or something for the LST2 and leave the Mach as is.. Really is kind of hard sometimes to decide which engine in what...

ps On a side-note, I did recently discover that when you go to ebay.com , if you search "dm one" instead of "dm-1" you find some better results.. - re prices and shipping costs.. Still impossible though to find a shop with 15-19 pinions AND reasonable prices and shipping...

whipnet

I am not sure if these transmission braces would help you, or if they would even work with nitro, but they work great for me.
