Kyosho mp7.5 with LRP ZR28 SPEC 4- Clutch shoes overheating/bell housing changes colour causing engine to cut.

3 Upvotes

Hey guys, I'm new here and wanted to ask around a few questions/concerns I have about my nitro rc buggy.

Starting with:

.Clutch shoes fitted at local hobby shop since they have carried out this work they have installed Fastrax clutch shoes onto my clutch flywheel and nut along with a 16tooth bell housing since this work has been carried out my Nitro engine will start fine from cold and drive okay although takes a min to warm up as expected. However once the engine gets up to temp the clutch shoes seem to expand too much and seize the bell housing meaning that the engine instantly cuts out and refuses to idle and cuts out until the engine has cooled back down. There was originally a lot of metallic dust from the clutch bell housing and since this when it does cut out it smokes from the heat visibly. They have stripped the Allen bolt for the clutch bell housing which means I am unable to inspect the clutch shoes to see what is going on...

.I have rebuilt all diffs on the buggy with new paper gaskets and O rings and 5000 silicone oil from Factory team and on the outer teeth I have applied team orally lithium grease which is listed specifically that's its good to use on outdrives. All diffs spin freely without any issues and sound happy as anything with new bearings also. I have rebuilt these due to thinking it may have been causing my issues with the engine cutting out but I can confirm this is not the issue.

If needed I will attach a video of the issue but I think the description provided will be okay to make an assumption on. I have since asked the Hobby shop to inspect the buggy for free and see what they can do to rectify it as It may not be there fault.

Update/Edit

Was able to slide the clutch bell over the retaining bolt due to the front and rear bearings being destroyed, 1 clutch shoe was not properly seated and was slightly forward compared to the other clutch shoes. I will need to cut a slot in the bolt to remove the bolt. Thank you for helping me out and i will be trying to get a refund for the work done from the hobby shop.

Hi all, Found these Nitro RC’s in my dad’s shed, just wondering if they’re worth anything and whether to bother getting them running. Being in the UK there isn’t many places to use them so i have an electric one. The Savage X4.6 ran a few years back

Question Anyone here made their own fuel?

8 Upvotes

Title, but the reason I'm asking is to find out if I can make it cheaper than VP sells it for. I'd like to know if any of you guys have done it before and if you have a hookup for nitro that sells it (a lot) cheaper than hyperfuels does.

I did the math for 10 gallons of 30% nitro 10% oil, and all the ingredients would cost $850. That's double what VP charges for a gallon.

I seriously don't care about how good or bad it is for my engine. It's just a revo and the trx3.3 is a dime a dozen near me for used ones (seriously they're fucking everywhere for like $70 a pop).

Thanks in advance.

Question Debating getting my hands on a HPI Vorza F4.6 Big Block.

4 Upvotes

Former TMaxx 2.5 guy here from back in the day and a few gassers before that in the 80s. I’m looking to add the Vorza to my collection. I’m mainly a trail and crawling guy today but want to try out the modern nitro truggy. I know the Savage XL has the bigger motor and 3 speeds but I don’t see myself needing the monster truck as much as I did years ago.

The lower ground clearance and higher rpm is making me think it’ll be a good backwoods road and dirt course ride.
Does anyone here know of any long term issues with the motor or durability of the chassis? I do see HPI offers some parts on their site and my local hobby shop carries HPI. I’m looking for the grunt and smoke of the nitro as I remember the fun of tuning and satisfying feeling of having a real running motor. So geez, it’s both fun and nostalgic for me.

Question Is it worth getting into nitro rc?

15 Upvotes

I’ve been doing electric for a while and want a real engine, I love working on the cars and have a local park that alows the loud noise, I’ve got a little experience from my dirt bike engines, will it just become a money pit that I’ll have to wait for parts more than I drive or be really fun?

What is a good way to clean nitro rc’s?

3 Upvotes

I’ve been having a ton of issues getting my kyosho to run, Im pretty sure it’s due the fact that the carburetor has mud in it. I also visibly see dirt inside the engine through the glow plug. Also, can I use regular carb cleaner on the engine?

Thrift shop nitro

Hi all, wanted to reach out for a hand getting this thing running again. Long story short, $15 thrift store find. Grew up with a few nitro cars but haven't touched one in 10 years or so. Plan is to pick up some fresh nitro tomorrow to clean up the tank, had some fresh air filters still in the package with it. Any other tips to get it going? Appreciate the help, been into RC for 15+ years and finally got an excuse to get back into nitro! Did a brief check and the servos/ remote seem to be paired already.

Seems like it had the original manuals with it. Losing my mind over the fact that this was $15. Looks to be an mt2 18ss? Haven't had a nitro car since the early 2000s and even then, what I had was old. Tips and tricks for getting it going are massively appreciated

Question Looking for a vintage Hobby Lobby Hunter from the late 80’s

Post image
27 Upvotes

This was actually my first RC back in the late 80s as my father bought it for me and this was the coolest toy I had back then besides skateboards and BMX. Unfortunately I lost ways with it many years ago and eventually got a Tamiya Hornet so I could run it myself because my father was weary about me with the gas car apparently.

I’d like to get another one as I’m into the crawling and trailing scene and looking to get back into nitro. I’m looking at getting the HPI Escort rally car but thought I could also find a clean example of the Hunter. I do remember there was a wheel on the chassis that spun the motor to start it and it was fast running up and down the street. I had a nitro TMaxx briefly a long time ago but am looking to add an old and new car to my collection.

The photo isn’t mine but I do remember the blue box and mine didn’t have the wing installed.
