Model Forum / Radio Controlled / Land Models / October 20063 motors in three months..........I'm on a roll!
Well, cooked another one this evening; that's three motors in the last 3 months! DAMN! 1. My buggy motor (Sportwerks .26) puked a few months back when it ate some dust at the track d/t an air filter leak. 2. Savage motor (S-25) wore out after 16 gallons last month. 3. Truggy motor (Sportwerks .26) started acting goofy this evening and when I yanked the motor apart I found a piece of the sleeve liner had flaked off, wedged itself between the piston and the sleeve and had actually wore a 2mm wide flat-spot on the side of the piston, from the very top to the very bottom! FWIW the motor had around 5-6 gallons on it (I lost count). So, I'm pretty p/o'ed! Goddamn truggy hasn't run right all summer. First it was that weird-a.s fuel delivery problem d/t a partially plugged in-tank filter, then it started eating clutch shoes left and right, and now the guts are fubared. The crank is grooved where the clutchbell bearings would be sitting as well, so I'm gunna keep it for parts and grab a new motor for it. Mach 427 here I come! Doc god i'm glad i've stuck to electric. : Well, cooked another one this evening; that's three motors in the last 3 : months! DAMN!

The Revo is flying (idle is a bit lumpy...) and still indestructable. Bad luck on the engine dude - sounds like that trug is jinxed - get shot and get one of those new Kyosho ones ;-)  SignatureDan - on his PC > Bad luck on the engine dude - sounds like that trug is jinxed - get shot > and get one of those new Kyosho ones ;-) Dude, those have been my exact thoughts for the past few months! The new ST-R's are BADDASS! Pricey though! Doc X-No-Archive: Damn...that's alot of fuel Doc. hmmm...what goes faster, the nitro fuel or the beer? > X-No-Archive: > > Damn...that's alot of fuel Doc. > hmmm...what goes faster, the nitro fuel or the beer? The beer <thankfully> as it's alot cheaper. When my buds and I bash, we'll run them for 1.5-2.0 hours nonstop, which equals about two quarts of fuel (4 fuel bottles worth), so two good bash sessions and I've drained a gallon. When I practice at the track I'll run em' for about an hour and a half so 1.5 quarts there as well. I actually looked into mixing up my own fuel, which on paper would save me a bundle, except for the bloody HAZMAT charges on the methanol and nitromethane which make it about even. Just broke in the new Mach 427 this evening. Ran three tanks thru her (heat cycled) and she's just about ready for the final tune! Doc > > X-No-Archive: > > [quoted text clipped - 13 lines] > Just broke in the new Mach 427 this evening. Ran three tanks thru her (heat > cycled) and she's just about ready for the final tune! What do you need to make your own nitro? Come on spill the secrets. > What do you need to make your own nitro? Come on spill the secrets. No secret really. You need: 1. Methanol 2. Nitromethane 3. Lube package (Klotz is a big one) All three need to be mixed according to the nitro/oil %'s you want. Doc Yeah...I heard it's really not too bad if you can use that much fuel. ie 30+ gallon batches. Although you need a good method to mix the fuel...without igniting the alchohol. Electric mixers near the fumes would probably not be a good thing. Also...gotta keep the fuel dry from air moisture. My local hobby shop charges almost $30 for Trinity 20% nitro/gallon. It definitely has gone up quickly in the last few years. Hey...what kinda of hazmat fees are we talking? just curious... > > What do you need to make your own nitro?

[quoted text clipped - 5 lines] > > Hey...what kinda of hazmat fees are we talking? just curious... 5 gallon pail of 99.90% pure methanol............$30. 1 gallon can of nitromethane = $40 2 quarts Klotz R/C Castor = $20 HAZMAT fees vary by product and volume but are approximately 25% of the original price. So, for enough juice to make 5 gallons or so of 20% nitro, minus the oil package we're looking at $30 (methanol) + $40 (nitro) + 25% (HAZMAT) = $87.50 + $20 (oil) = $ 107.50 I can get O'Donnels 20% race blend by the case at $22/gallon. That's $110 for 5 gallons, a mere $2.50 more than having to mix it myself. Doc > > Hey...what kinda of hazmat fees are we talking? just curious... > [quoted text clipped - 13 lines] > > Doc Yeah...the numbers don't look so good. Maybe the key is to do more volume...like 30+ gallon drums. :) How about a 30 gallon drum of Meth(anol) picked up locally? >> > Hey...what kinda of hazmat fees are we talking? just curious... >> [quoted text clipped - 19 lines] > volume...like 30+ gallon drums. :) > How about a 30 gallon drum of Meth(anol) picked up locally? You're right, if you could do it in bulk and not have to pay HAZMAT fees you'd be in like flint. Problem is, 30 gallons of methanol = 50 gallons of mixed fuel and I a) couldn't use that much in a reasonable time frame; b) have nowhere to store it that's cool enough to be safe; c) don't feel like having 50 gallons of highly flammable liquids laying around!!! Doc > Well, cooked another one this evening; that's three motors in the last 3 > months! DAMN! [quoted text clipped - 19 lines] > > Doc So do you know what engine is going to replace it allready?? Or is that why you said "Mach 427 here I come!"?? Cheers Dre >> Well, cooked another one this evening; that's three motors in the last 3 >> months! DAMN! [quoted text clipped - 25 lines] > > Cheers Dre Yeah, I nabbed a Mach 427 for $103 delivered from the bay.' Essentially the same motor as a Sportwerks .26 with more aggressive porting and a different carb. It's the stock motor on the LST2 and the new Muggy from Losi. I'm hooked on Dynamite engines. I'll run em' till the day I die. Cheap as dirt and they outperform pretty much everything else out there. The new Platinum line looks promising! I was thinking of grabbing a .21 for the Kanai to make it ROAR legal. On that subject, I just ordered some OFNA full-offset MT dish wheels and some Panther Komodo low-profile tires to convert the Kanai into a short-wheelbase truggy of sorts. We'll see how she does on Monday. Now I just gotta snap some damn pics of everything and get my website up and running. The Savage is absolutely gorgeous right now with the recent additions, and the Mayhem ST has changed quite a bit since the last round of pics I snapped.

[quoted text clipped - 44 lines] > > Doc Nice, I'm allways interested to hear about these types of engines, the cheap performers caus elike you say, they are cheap as dirt so who cares if you snot one :) I've got my pics sorted, just need to put them up somewhere. Looks like a shitty w/e re the weather down here so I might have time to do it! Cheers Dre > Nice, I'm allways interested to hear about these types of engines, the > cheap performers caus elike you say, they are cheap as dirt so who cares [quoted text clipped - 4 lines] > > Cheers Dre Grab a Sportwerks .26, run it with HPI Polished pipe, 16/49 gearing and Mugen alu shoes with 1.0 springs in yer' Savage and you will NOT be disappointed! Damn thing is an animal! It eats K4.6's for breakfast now! They sell pretty much everywhere for $129USD. If you're patient you'll find one on the Bay' for under a hundred on occasion. I have the same motor in my Kanai, running a THS 8015T pipe with 14T clutchbell and carbon shoes + 1.0 springs and it's a land missle as well. Put it this way, the owner of the track I run at has a huge hobby shop and has access to pretty much anything he wants for what he pays for it. He runs a Sportwerks .26 in his Mugen buggy, his Kyosho ST-R and in his Savage. He's got the Rossi's and Picco's there, but he says the Sportwerks motors perform better regardless of cost. Doc >> Nice, I'm allways interested to hear about these types of engines, the >> cheap performers caus elike you say, they are cheap as dirt so who cares [quoted text clipped - 20 lines] > > Doc No sh.t! They sound like monster motors! So have you run yours against a K4.6 powered Savage?? I run a K46, 16/48 gearing, 1.1mm mugen springs in the clutch, currently have the ribbed pipe on there but have the polished one to try out. You really think it'd give me a big improvement?? Cheers Dre > No sh.t! They sound like monster motors! > [quoted text clipped - 5 lines] > > Cheers Dre On the bottom end you wouldn't notice too much, but on the top end...............the SWK .26 revs out 10K higher than the K4.6. I've raced a K4.6 Savage since this upgrade, same gearing, both had 3-speeds as well. We were dead even until 3rd gear; when I hit third I just left him in my dust as he revved out while I was still accelerating. Here are some specs from the XRC dyno: HPI Nitro Star K4.6 1.32 @ 22,250 rpm 59.52 oz-in @ 19,750 rpm 35,000 rpm w/ kit $200 HPI K4.6HO 1.28 @ 19,500 rpm 64.76 oz-in @ 19,500 rpm 32,000 rpm w/ kit n/a Sportwerks 0.26 1.30 @ 26,750 rpm 53.76 oz-in @ 19,000 rpm 42,750 rpm w/ kit n/a Team Losi Mach 427 1.31 @ 26,750 rpm 53.80 oz-in @18,750 rpm 43,250 rpm w/ kit n/a I have also destroyed an MGT 4.60SE (no chance!!) and my bud's O.S. .18-powered T-Maxx (also no chance). I'm a top-end guy. I prefer tons of top-end power and revs than gobs of bottom-end torque which just produces uncontrollable wheelies anyways................. Doc >> No sh.t! They sound like monster motors! >> [quoted text clipped - 29 lines] > > Doc Well I might need a new motor soon cause yesterday I couldn't keep my K46 running. It'd scream when you floored it, but as soon as you put the brakes on for more than a second, stall. Wouldn't idle either BUT I'm hoping it was the plug, I didn't bring any spares with me (why is it whenever I sh.t a plug, I've never brought a spare with me??!??!). OTOH, when you take the plug out, it has very very little pinch... Meh, see what happens next time I run it. Do you know if you can get a Nova head for the sportwerks?? (I cant have a *blue* engine head in my black/silver/purple savage :) Cheers Dre Yes... http://cgi.ebay.com/Sportwerks-Mayhem-26-Nova-Race-Pro-Cooling-Head_W0QQitemZ605 7185586QQihZ009QQcategoryZ19168QQrdZ1QQssPageNameZWD1VQQcmdZViewItem > >> No sh.t!

Okay so there is one new one on ebay, 6 days to go, I'll see how that one turns out! Wish me luck :) Actually I've been meaning to ask this for ages. If you buy a new motor is it recommended to run it in first *before* plopping one of these Nova heads on?? (purely due to it being easier to get to temp with a stock head). Or doesn't it make any diff... Cheers Dre > > Yes... http://cgi.ebay.com/Sportwerks-Mayhem-26-Nova-Race-Pro-Cooling-Head_W0QQitemZ605 7185586QQihZ009QQcategoryZ19168QQrdZ1QQssPageNameZWD1VQQcmdZViewItem > >> >> No sh.t! They sound like monster motors! > >> >> [quoted text clipped - 73 lines] > > Cheers Dre Yes, I have always broke the motor in with the factory head and pipe before adding the upgrades. I don't see any reason to do it any other way as you wouldn't see the gain (or loss) in performance as opposed to the factory setup. And yes, the Nova Head would keep your temps down more so your heat cycle might not fair as well. HTH PS.. If there is a Best Offer option on the Nova head..email the seller and see what the best deal is and save a few $. >> > Yes... >> > [quoted text clipped - 101 lines] > and > see what the best deal is and save a few $. Nice, thats what I was thinking... Well I'm starting to get a bit excited about the potential engine upgrade :) I think the head did have a best offer so I'll give it a try, worst case I pay the auction price (which is still quite reasonable) Thanks for the info! What do you run in your Savage btw?? Cheers Dre > > Yes, I have always broke the motor in with the factory head and pipe > > before [quoted text clipped - 22 lines] > > Cheers Dre I have a Nova Pro Race Head on the factory .25 with a CVEC adjustable tuned pipe on the Savage. Just installed a Nova Head and same CVEC pipe on my new Ofna Ravager Force.28 after I broke it in and ran it for a couple of tanks after break in...Haven't got to run it yet with the new stuff 'cause of rain, rain, rain! =( >> > Yes, I have always broke the motor in with the factory head and pipe >> > before [quoted text clipped - 34 lines] > in...Haven't got to run it yet with the new stuff 'cause of rain, rain, > rain! =( Nice! Hehe, it was grey and raining yesterday, then blue skies and sun, then grey and raining, then blue skies and sun, repeat lots :) Right, so Nova heads are the go then, I'm convinced, pity they dont make a purple annodized one, or do they? goes off to look... Cheers Dre >>> > Yes, I have always broke the motor in with the factory head and pipe >>> > before [quoted text clipped - 46 lines] > > Cheers Dre Well it doesn't look like they do *anything* in colour, all silver. Oh well, silver is better than blue :) Cheers Dre > Actually I've been meaning to ask this for ages.

I did have it installed on my Mayhem ST before, but when she puked I swapped it over to the Savage. The Mach 427 is broken in and tuned. Much different engine than the SWK .26, given that internally they're almost identical aside from the porting. It's not quite as ballsy as the SWK .26 IMO, but it might just be the pipe. I'm gunna slap an HPI polished jobbie oh her sometime soon and give her a run. Doc >> Do you know if you can get a Nova head for the sportwerks?? (I cant have >> a *blue* engine head in my black/silver/purple savage :) [quoted text clipped - 10 lines] > > Doc Righto, well I'm watching a new sportwerks .26 on ebay atm, ends in 6 days, if it stays cheap I'll pick it up along with a Nova head. Get this, I got a polished pipe from Tower last week. It arrrived but it has a dent in the side. I emailled Tower and said, how do I return for refund, they told me to throw it out, they'll send a replacement airmail! How cool is that? I'm certainly most happy with that! Cheers Dre |
