Hey everyone, was making this thread to see if anyone knew of anyone who offers services for nitro engine repairs? I have a FX engine thats been started 4 or 5 times, not even through 1 tank of fuel and has problems from the 1st initial startup that I can't seem to understand. I wanted to send it to someone who repairs/tunes nitro engines.

I've reached out to the ones I found on google search (rcrenew, EBmods) and neither of them can seem to help. Anyone know any places out there than can help?

Exactly what issues are you having? Have you broke in a high-end race motor before?

To many that I can't seem to diagnose and subsequently can't fix with the help of others in hobby and this forum (including you 🤣🤣). So I'm trying to send it to someone who offers repair/tuning services to diagnose whats wrong with this crap engine.

And no, I havent broke in a "high-end" race motor.
 
The first place I'd try would be a local hobby shop. Next I'd look for a local RC track or even an RC flying club.
Pretty much any place you can find someone who knows about nitro motors.

I am also very much a do it myself person so before I gave up on this and spent my hard earned money on this, I'd give another go or 2 at it from step 1 and work out the problem(s).

Nitro is pretty straightforward once you get a bit of experience with it.

@Littlemotor is a super smart nitro guy. I would REALLY try to work with him on this issue if I couldn't get this done on my own.

I don't know of anyone you can send your motor to. Maybe you can find a nitro motor tuner who can help you.

I think if I were a motor tuner, my suggest to you would be to buy one of my pre tuned, pre run, usually very expensive race engines. (because thats how they make their money)😉
 
Any help anyone?
You know dude, you have to help yourself, and by responding to Littlemotor's "Exactly what issues are you having?" inquiry with "To many that I can't seem to diagnose and subsequently can't fix..." doesn't help; and is pretty much a showstopper.

CertifiedMike gave you great advice with "@Littlemotor is a super smart nitro guy. I would REALLY try to work with him on this issue..."

Can you describe what is or is not happening?
Have you fiddled with or adjusted any carb needle settings?
- "I have a FX engine thats been started 4 or 5 times, not even through 1 tank of fuel and has problems from the 1st initial startup..."
So, it has been started and not run through a full tank.
How long does it run, when does it die - like when you detach the igniter - or when you try and gun it?
Will it not start again?
Do you have a temp gun?
What temperature did it reach?
I'm assuming it's a bump start - does it turn the engine over or is it (the engine) stuck?
Did you prime the fuel?
Are you flooding it and getting a hydro-lock situation?
Have you replaced the glow plug and tried that.
Did a manual accompany the engine, and did you read it?

Appreciate the reply and I've done exactly what you mentioned.


I've done everything recommend by everyone, did pressure tests looking for air leaks in the engine and tank,taken it to my local hobby shop to people who have way more experience than I do with nitro engines and they are all puzzled and the engine still doesn't function. Every recommendation made by anyone in this forum, I've found on the internet and have been told by those at my local hobby shop, I've done and people have helped me with personally.

Only thing I can think of is that there is something mechanically and or structurely wrong with this engine

Who is Ed?
You said EBMods “didn't seem able to help”.. Ed Bridges is the owner/operator of EBMods, and offers EBIS WITH dyno tune. So I’d like to know exactly what he had to say-being he offers the service you are looking for.

He stated he doesn't have the time to look over a non functioning engine. He is spending his time with break ins/ tuning etc.
 
Have you actually taken the motor apart? Seems like you could find internal damage as well as the next person.
Honestly, being a newbie getting back into nitro, id rather leave it to people who actually know what they're doing and what to look for. I'm the same with my actual vehicle. I'll do my brakes, but everything beyond that, ill leave to the professionals.

Not to point out the obvious, but….. A lot of times it’s not so much what you say; but how you say it.. IE- “I’d like an EBIS, and dyno tune sir.”.. Problem(s) solved.

If I were to call, or email an engine guru who provides high end nitro race engine services, and tell him 73 reasons why I think my ONLY high end race engine is cursed, or defective; I can tell you that without ANY doubt-he will not want anything to do with that motor, or me as a customer.

OS Speed, and FX Royal Engines, are arguably THE most high quality, nitro race engines available. You’ve never owned one, let alone broken one in. Unfortunately, the fact that you can’t make it past “4-5 starts”, let alone the first idle tank tells the moral majority of us who have literal DECADES of experience breaking in uber tight nitro race engines, that it’s likely NOT the engine… I’m absolutely positive that’s not at all what you WANT to hear, but if you simply stood beside me and watched the process of what I go through to break one in; you’d understand that it’s VERY common for someone who’s never done it before to have the exact experience that you are having. Now I absolutely will agree that nobody has an absolutely spotless track record, and things can happen, but in this particular case, and with this particular engine; I seriously doubt that the engine is at fault. This is NOT a jab, nor any kind of “attack” on you-it’s just an explanation of my opinion on the situation.

I literally JUST helped a fella in your shoes EXACTLY-though he did have SOME nitro experience at least (20yrs ago), and he was having ALL the exact same issues as you are. He’s just bought his FIFTH OS Speed race engine in less than two months, and has been bitten by the nitro bug HARD since I helped him get sorted out. He’s also a member here. Once he became receptive to the possibility that he lacked the experience and know how, he began to learn. First tank… Second tank.. On the ground running, had problems again (AS EXPECTED, the tune is CONSTANTLY changing in a brand new engine with EXTREME mechanical pinch), trusted me, and was able to work through the problems together, became more proficient in tuning, and let go of the bad habits he was picking up solo, to now-he’s sending me videos of running all day long, and is even teaching HIS WIFE..

With the right attitude, and PATIENCE, anyone can succeed in nitro. I was a noob once too. 🤷🏻‍♂️
 
I understand your concern. I guess I am just the opposite. I need to know. I need to understand and see it work.
Your issue can be found out. You just need to jump in and get it done.

If you can do a brake job, a nitro motor should be pretty straightforward. 👍
 
Davidwebb911 - "I'll do my brakes, but everything beyond that, ill leave to the professionals."

As CertifiedMike mentioned "If you can do a brake job, a nitro motor should be pretty straightforward."

One of the aspects of this hobby is how much wrenching you can and will end up doing.
Regardless of nitro or electric - drivetrains, suspensions, diffs, etc. - something somewhere will need to be repaired.
Nitro engines come with their own idiosyncrasies and can be a royal pain at times.

There are also less knowledgeable nitro resources around these days.
30 years ago, every hobby store had at least one person who knew their way around a nitro engine and could answer your questions.
No one in the last two that I visited ever ran a nitro vehicle, all they knew was electric.
If I was just being introduced (or reintroduced), I would lean electric given the aforementioned - and the current performance capabilities provided via modern electronic technology.

My problem is that electrics don't stir my soul, I still like the sound produced by a good engine and pipe combo.
If you forge ahead and get this engine tuned and running, you'll discover a new level of performance induced enjoyment that average engines can only hint at.
If you "leave it to the professionals" to handle your engine issues, your car/truck/truggy will spend more time on someone else's bench and you'll be playing a waiting game more than the driving game.

As I have stated before, I've taken the engine to people who have way more nitro experience than I do and even they can't figure out what's going on nor get the engine to run, which is telling. I've never doubted user error wasn't part of the problem and I've tried damn near everything recommended to me by those who know this part of the hobby from front to back and still same issue.

Just because something is considered top notch or best of the best, doesn't mean everything is always perfect. I'm a car nut and a car collector waited 4 years for a Jesko hyper car and within 80 miles of delivery, the car broke down. Same collector has another hyper car from the same manufacturer and it has never properly worked and these are multi million dollar cars.

I made this thread to see if anyone knew of anyone who works on nitro engines, so I could send it in to another set of eyes and see if they can figure out what's going on.
 
To many that I can't seem to diagnose and subsequently can't fix with the help of others in hobby and this forum (including you 🤣🤣). So I'm trying to send it to someone who offers repair/tuning services to diagnose whats wrong with this crap engine.

And no, I havent broke in a "high-end" race motor.
David Little motor is extremely experienced and he knows this stuff inside out if anyone could help you he is the man.

I started this hobby long ago in nitro. I had a nitro 4tec, HPI Rs4, my very first heli was nitro. I got out of nitro cause of all the mess that comes with nitro and electric was SO much cleaner, better running and brought an ease to the hobby.

This car was literally just a "let's have fun with it" thing and hasn't been touched since October I believe. I'm not going full hardcore back in nitro as I very much prefer electric in my cars and every single one of my heli's. That's why I'm not sweating this engine as the end all be all. I'm trying to send it to someone and see what they think as like a last ditch effort and if that doesn't happen, it'll be in the trash and back where I was before I decided to dip my toe back into nitro lol.
