I this that's what he did. I marked his flywheel so there was no guessing and he probably just didn't pay attention to it BUT... The buggy arrived today and I will be breaking it in in the next couple days!

I have a question about my friends buggy and seeing as he won't make an account I'll just ask for him lol he has a Redcat shockwave and he broke it in per the book (old school shoe box method) and well I was looking at it one day and I noticed the engine was stuck. Like a bad bearing, rusted stuck. But I messed with the flywheel and it began to move and eventually it turned over freely and when he ran it there was no abnormal noise and when it was hot I shut it off and there was no drag like before. Could he have left the engine around TDC and the piston have gotten stuck?

Ok by the sounds of it, I should have enough fuel to make it through break in and then a few tanka after that I'm hoping ill get the buggy tomorrow or Friday by the latest

Just a small update. The new buggy was shipped out today so I should have it this week . Also I got a new phone so this forum will be much easier for me to use! Anthoop what procedure do you use for engine break in? I know it's the heat cycle method but I can't remember what you said specifically on my deleted thread

Ok well i think I've got it figured out. I'm going to get some hot plugs for break in and go with one LC3 and one LC4 and see which does better for me and then stick with that plug.

I'm measuring the plug just like in the pic you posted with the green lines and it is either 5/16 or 3/8 of an inch. My eyes can't quite distinguish the slight difference. Either way with the tape measure its is equivalent to 9.525mm but I will measure it again tomorrow with a digital caliper set to mm to see what it is. And I just thought of this but I held my 3mm Allen key to it and it seems to be closer to the 4.5 or 5.5. I prefer using mm and other metric measurements as to me its more precise. Plus easier to work with. All in all if its 4.5 then I will go with some OS 8 plugs and if its longer I will go with the LC4 plugs. Would it be better for me yo break the engine in on a hot plug like I did the first time or just use the medium heat plugs?

Mc-59's are really expensive here where I'm at. I'll dig around online and see what I can find deal wise but honestly I want to figure out what glow plugs I'm going to be running and have them on order. I don't have a lot of money to just throw at glow plugs in hopes that they will work for me. I see a lot of people saying that such and such plug works great for me but I never see anything to back that up. I don't see a previous history of what they've used and done to their engine. Or even what the weathers like when they used said plug. I'm looking at the R5 plugs mainly because I'm running a higher nitro content and I'm running the engine hard. And from my research a cold plug will do me better. I need someone that has a good understanding of the whole glow plug situation and can answer my specific questions. Its just like I've seen some people say that OS plugs are crap and that enya plugs are the best ever and then I've seen the exact opposite. I'm not looking for a use this plug and you'll be golden answer I'm looking for a place to start that makes sense to me without having to buy tons of different plugs. And not knowing the manufacturer of the stock plug in the jl .28 makes things even stranger because I can't find out if its a hot medium or cold plug. Its not like we can hook these engines up to a timing light to see what's going on to some degree. And the thing that annoys me the most is that there isn't one single standard thing between all of the plugs out there except that they're a coil of wire in a metal housing. Yes its starting to frustrate me seeing as no matter what I type in I can never find a specific answer to what I would deem a simple question

The thread length on these HSP N3 plugs is 3/8 inch or 9.525mm without the sealing ring. That seems really long to me. In the manual for the hyper is says B3 and B4 glow plugs are recommended but I can't find any "B" glow plugs anywhere online. Are the plugs I already have a long reach plug? If so I'm going to get either the lc plugs or the McCoy plugs depending on what the hippy shop stocks more of. I'm going to get 2 of each plugplug (hot and medium) and just break the engine in on the plug that comes with the buggy and this N3 that I already have. It still glows super bright. I'm probably getting the replacement next week seeing as the buggy was being sent back via the postal service.

Could one of you measure a long reach plugplug like the lc3 or 4 and then a "standard" plug?

I'm starting to get annoyed with the fact that I can't find certain information that I could easily find a few weeks ago. The jl .28 is a long plug type engine isn't it? I see an OS #8 and an LC4 side by side and there's a major difference in length. And looking at the N3 plugs I have here they look like they're short plugs. If its supposed to be a long reach plug then why would they send out a buggy with a short plug? Production costs? This is the most confusing thing I've ever had to pick out something on as nowhere online has specifics. Also should I be running a hot plug or a medium to cold plug? Obviously I'm running 20% traxxas and run a lot. I don't want to buy a plugplug(s) and not actually need to.

I would like to stick with a long reach plug which the os8 isn't. As for fuel I'm just going to stick with traxxas seeing as its widely available around here.

I have a question that I thought I knew the answer to and since then have confused myself and instead of starting a new thread I'll just keep all my stuff on this one for now. The .28 comes with an "N4" glow plug standard. I've read on some places that its a "super hot" (and yet there is an N3 plug) and then on other places I've read its a medium heat range plug. Between the N3 and the N4 which would be the more appropriate plug? And what other brands would be best for me to switch to? The local hobby shop wants almost $9 for the McCoy plugs and only $7 for the LC3 and 4. The OS #8 is in between at around $8. I see traxxas has their own plugs, the ones I looked at were the 3232x. I can't remember the heat range. There's just too many companies with so many glow plugs haha. I'd like to stick with a long reach plug though. Its heading into cooler weather here (next month temps are going to start falling more) but for now we'll have a really comfortable day in I'd say the upper 60's and then the next day its chilly and windy. Then the day after that its raining. With the wild weather would I be better off with the N4 or equivalent glow plugs or would it be a good idea to go to the one of thethe other plugs? If so which one? And yes anthoop I know I'm asking questions all over again from my thread that you helped me with originally but it got lost with the server failure and I can't for the life of me remember what all was said. Also after searching I can get a good deal on 6 of the N3 glow plugs for about $16 so I believe that averages out to about $3 per plug. I will keep looking for a group of N4 plugs. Also at the hobby shop he carries traxxas fuels and blue thunder. I have half a gallon left of traxxas. Should I switch to blue thunder in your opinion? (I'm still reading up about it). There is also a few other hobby shops about 45 minutes away from me that I could check into for fuel but I'd like to stick to the closer shop if possible due to gas mileage. That $30 gallon of nitro fuel will turn into a $50-$60 gallon after I factor in gas burnt there and back.

Well guys its not much of an update but I boxed the buggy back up today and its on its way back to the hobby shop. I wish the local shop had this kind of service haha they can't even give me one answer on a fuel that they're a dealer for! One guy told me that they couldn't get it at all and then another guy told me that it could be ordered. Either way I'm excited and nervous at the same time.

Your opinion matches mine exactly. Tomorrow morning I am going to be sending the buggy out for a replacement and just starting over from the beginning. It shouldnt be too much longer and i will be up and running again.

The cylinder is damage free but looking at the intake port, metal got pushed out of the intake and sucked back in and scored the surface right there and I'm still missing a piece of the piston skirt. The dealer offered to give me a refund or a replacement also.

I'm on a computer now so i will try and upload more pics. as for fuel I'm using traxxas 20%. My Hsn is at 3 1/4 turns out and my Lsn is a few hours shy from 2 full turns out from flush.

I'm happy with the performance this engine had but if this is a possible problem then I'd be more inclined to go with a better engine. What makes the 3 port .21 so good? I'm not set on any engine in particular but I want one that has a good amount of torque with a decent amount of power for instant response (I know a lot of that has to do with the pipe too) could the fuel I'm using have anything to do with this? And as far as sending it back and taking pics I've contacted both the dealer (purchased online) and ofna to see what can be done. The rest of the buggy minus the clutch bell bearings has been outstanding. Upon disassembly I found the outer bell bearing had slop in it. Just enough to let the bell rub the flywheel and leave a black mark.

It was brand new. When I slowed down after it passed me to turnturn, the engine slowed down as I let off the gas and then all this happened. The glow plug was full of metal and theres metal everywhere. I could barely get the cylinder out lol I'll know more tomorrow though hopefully. Any recommendations on a different brand engine for this buggy? I've looked into go engines, nova, basically most of the major names. Oh and what's the difference between a BB exhaust port and a SB exhaust port and header/ manifold? I've seen that come up a few times. And I'm probably gonna get a better pipe with the new/ better engine if I go that route.

Let me know if it dosnt show up

Ok guys om not sure who remembers m other thread that got lost recently but I finally got the buggy and took the whole day to break it in. I still had it tuned rich and me and m buddy decided to run in an open field with short grass. The width of this field is about 100 feet max with a dip in the middle. Well I went from one side of the field towards me through the dip slacking off as it came out of it and then I got back on it and as it passed me it began to die down and flame out. This whole issue took place in about 70 feet total at about 3/4 throttle. I walked over to it and went to pull the pull cord and it wouldn't budge. I let it cool down only to notice the flywheel would move a little. Pulled the plug and the piston was stuck all the way down. Got home took it apart and found my worst fear on an engine with about 2/3 of a gallon through it. My pictures are too big to upload so I will try resizing them
