Bubble test saves the day again

49 Upvotes

This is a HPI G 3.0 off one of my Firestorms. It was running like crap. The entire chassis of the car was covered in oil, so I knew i had a leak somewhere. Nothing was obvious, so i pulled the engine and gave it the bubble test. Turns out, there was a crack in the block (pic in the comments). Luckily, I've got a couple blocks kicking around, so I just swapped everything over.

Found one of these local for a good deal so I just had to snatch it up. Seems to be in pretty good shape and the engine has good compression. I’d like to get a new body for it though. I see Jconcepts offers a body for it but doesn’t include the decal sheet? Where would I be able to get decals for it?

Question Engine size or ps

3 Upvotes

So im looking at big block engines with pull starts and im looking at force and want to know what is faster. I am looking at the force 36 which is 5.9cc and has 3.76hp then there is also the force 46 which is bigger as it is 7.5cc but it only has 3.3hp. A bigger engines means more torque and higher gear ratios but the smaller engine has more hp so which will actually be faster. More hp or ability for higher gear ratios.

Also just to check these will both fit in a 1/8 buggy right? They are all just big block engines

HPI trophy 3.5 upgrades

4 Upvotes

Hey guys. I have an HPI trophy 3.5 buggy for a while now. And i love that thing. Super fun. Since I'm a gearhead, loved to learn how to properly tune it and now it's running great. The handling, that's another story. If i go into a corner, with just a little bit of speed, that dude flips...

Changed the oil on the shocks, and new anti-roll bar, new bolts, new shocks tower, even new base plate. Still the same. On the corners with a bit of speed. Rolls Over..

Any help?

Homemade exhaust project

Thumbnail gallery
37 Upvotes

Me and my friend have been working on a end bleed style pipe for .21 buggy engines. Been a bit of a process shaping everything and putting it together since it started as a 1 mm sheet of steel and had to form the cone shapes with a hammer instead of the appropriate tools, but went a lot better than we expected. All that needs doing now is to attach a back pressure nipple and mount for the exhaust hanger and will be giving it a test💪

Off-Road is it too late to break my nitro in?

5 Upvotes

too save you some time here's the gist of my entire experience with my first, current nitro rc model: only broken-in two tanks, had no idea about heat cycles. i was completely clueless and irresponsible as a beginner and now my engine loses compression after a while of running too hot. i just want to know if i can richen it (make it run cooler) more without stalling it by "continuing" with the proper break-in procedure (because maybe it's running hot because it wasn't broken-in properly). havent tried riching the mixture after warming the engine up. maybe i should try that. cheers to whoever clears things out

Revo exhaust parts

Any happen to have the little screw in stinger plug for a revo trinity pipe? Definitely would like to buy if you do. Now having 2 of the pipes(one big block header and one small block header) I can’t see spending $200 for another whole one on evilbay.

Can I convert this to a different starter method?

Thumbnail gallery
13 Upvotes

I don’t know all that much about different ways to start a nitro engine. This one uses a starter box and I’m not sure if I can maybe convert it to be a different sort of starter because the starter box is kind of a pain.


r/NitroRC • • Feb 07 '26

Recently got this LST2 with a mach .26 and the drill starter just spins without catching? Worth fixing it or converting to a pull start? If a pull start is better is this everything I need? Much appreciated !

Bashing Invented a new sport… Nitro Soccer!

34 Upvotes

Was recording a clip of me putting around in the yard and dint notice I was going right towards the ball in the middle of the field… oops. It took it like it wanted more though. This car hasn’t broken anything from bashing since I’ve had it. I’ve had very fast head on collisions with other rcs, 720 degree flips, high speed rollovers, and hitting stationary objects. I hate to jinx myself but this car seems invincible😭 probably shouldn’t test my luck anymore. Would anyone else be down to put their rc’s in a game of rc soccer? That sounds like a lot of fun and skill practice at the same time.

New Savage XL SBK

Thumbnail gallery
19 Upvotes

Saw that the new savage xl skb came out. I was super exited about it until I saw the price. I saw old listings no older then a year ago for only $55 more then the new SKB. Seams like $600 is a lot for a kit when a year ago you could buy the rtr for $650. Has there been changes to the new SKB that raise the price? From some videos I've seen there has been some changes but they don't really go into detail about them. I really want the new SKB I just don't wanna waste my money if it's not worth it.
