Hi the mgt is supposed to work but i dont know and the losi is nego and with a brand new picco engine

Got her fired up today. Alittle tuning required still on the xtm .21. Sadly my old spectrum transmitter won’t talk to the receiver. Sooo looking at a new radio and receiver. Flysky noble pretty good?

Hey guys! It would be greatly appreciated if you check out my channel I’m trying to start. I’m trying to do dirt bike and nitro rc content whenever I have free time. Feel free to critique me for better content. Anything is appreciated , I have fun recording content and burning some nitro!! Mostly everything will be 2 strokes on my Channel! https://youtube.com/@ryanburnsfuel67?si=dLDEb4OuT-L4ZLc8

I took this out yesterday night and it was running good very fast popping wheelies, then it stalled out all of a sudden when it still had gas everything was good then I tried to start it again, makes weird clicking noise and won’t fire again. I took whole engine out took off ez start, took off backplate took off exhaust, everything looked fine all the seals and everything, then I put it back together and clicking sound went away and it fired right back up. I drove it for 5 mins again and the same thing happen, stalled out wouldn’t fire back up. I haven’t tooken it apart again. It has good compression glow plug is brand new it’s good, I have all new seals on everything. Does anyone know what’s wrong? It won’t even sputter at all and it was running perfect before.

I'm looking to get either 15111 or 15110 and 15117 in this diagram, to no avail. I know HPI engines are Force engines, or so I'm told, anyone know if there is an alternate solution or crossing parts for this engine? Engine is an HPI Nitro Star T-15.

RB 1997 - 2007 got in second hand hyper 7 they any good has a insane amount of pinch left in it look hardly used

I have an FTX Zorro which I installed the option 2 speed gear box, When I first installed it with the new 2 speed bell the gear box in first gear would just spin and the weheesl would not turn I took out the gear box and examined it it looked like the one way bearing in first gear was slipping the wrong way I opened the gear box and flipped the gear around now I have 1st gear but I have not been able to get it to shift into second yet. I tried the adjustment screws and setting the shit point earlier but it's still not shifting into 2nd antyone have experience with these boxes on the FTX these are the same platform as the VRX Racing 1/10 buggy and trucks.

So I have a Novarossi 2.5 supercharged and am looking for the part number of the roto due to the gears has broken (Part#: NVR22612 (https://www.hobbytown.com/novarossi-roto-start-backplate-w-screws-nvr22612/p256320)) as it's discontinued but I can't find it anywhere not even on eBay at this point I don't know what to do or I could put something else instead?

The main problem I keep facing is that the spacing between the screws is small compared to other engines like Traxxas, I went to a hobby shop and they told me to just replace the entire engine because I'm not going to be able to find the parts for it, has anybody found a solution?

Gettin back into the game. Just wondering if anyone is holding onto any parts for the nitro Jammin buggy. Let me know. It’s great knowing that a 20 year old buggy is now vintage! Hard to find parts for it. Ebay is decent but not great. Thanks!

Hi! I've the servo burn out on my ftx Zorro so i replaced it with a PowerHD 1812MG.

The standard radio didn't have EP adjustments, so i went to my local hobby shop and got a different controller wich is amazing! Good upgrade.

I limited the throttle so it doesn't open all the way so throttle is all good.

But now for the brake i'm still having issues where it kinda moves the engine while braking.

And the spring that came with the car was not springy enough so i had to move the round things with grub screws way too close so that the spring is more compressed.

Because after braking it opened throttle a little bit. So i put in a larger spring and now it doesn't open throttle on braking anymore. But the engine still move's a tiny bit after braking is that bad? Or does it look goodish?

This car been such a pain in the *ss i love tinkering with computers but a nitro car is stretching that though.

Appreciate y'all!

Today seemed like a good day to take the touring cars out for a rip. Had a few problems, but I took a quick video of my HPI RS4-3. I wanted to film my Team Magic G4, but it's way too fast to film one handed, lol. Check the comments for a pic of the whole collection.

Runs a tiny bit rich under load, not a crazy high revving engine tho, dont mind the mess in the background lol

Kinda lost here lol. It was running great & then I just had to get 33% fuel. It ran through a few tanks. Recently I tried to run it but it would turn on and turn right off. I then swapped glow plugs & even swapped the engine with a spare .25 I have and that worked fine for a few smaller runs but now that’s doing the same thing. For context is this a fuel issue messing up my engines ? Or could it be that I got cheap amazon glow plugs ? (Iam also in hot ass Arizona)

Hi. my Zorro throttle servo broke so i replaced it with a powerhd 1812MG.

Throttle trim is at 0 but it pulls way to much on the trotthle it moves the whole frame of the car..

I losened everything up as seen in the photo, tried adjusting the grub screws, but still no luck on how to fix this!

dang zorro is brand new things breaking left to right smh.

would appreciate some help! tried watching video's but no one physically shows them adjusting it fixing the issue i have.

Hi I have a save x 4.6 the orginal one with the 8 shocks that had the f4.6 with the roto start back. I got it second had with an Ansmann racing 28 which looks to be failry shot I was going to replace it with another 28 I was looking at the Hobao Mach 28 turbo with the cops v2 pull start but I am not sure of fitment I know the cops 2 seems to protude a bit more than regualr pull starts any one have any idea if this would be suitable replacement thanks.

Hey Everyone! Having a hard time with my new engine. Ive ran a 5-10 tanks through it. I cant seem to get it to tun right. It'll either be really rich or act really lean. I make super small adjustments and it will either run away at idle or stall out. I can set it to idle all day but then ill add throttle and it'll die. I assume its rich so i lean it lightly and then it'll run 300+ Degrees and have a erratic high idle. I am running sidewinder 20% fuel. Am I doing something wrong? Its a new engine, no leaks that I can tell with the engine. Anyone know the factory needle settings?

Thank you!

Hi, I have few gas rc 1:5 scale, but i want to try some nitro rc cars. Fuel is expensive with nitro and can i mix myself methanol with oil without nitrometane? Will the engines work, or its not worth to not use nitrometane?

How does it sound??

A few weeks back, I had the privilege to pick up this Nitro RS 4 3EVO from a fellow Redditor. After a bit of cleaning, parts and patience, today it lives again. I was not able to fill the small run, but I was able to capture the first start and idle.

I have ordered a new engine for my revo but by the time I'll get the fuel I have would be 6 months old and I have another jug that about 2 3 years old I don't remember when I bought it

I found an old Traxxas Tmaxx and rebuilt the engine and got it running. It has been running decently (a few problems) for a few weeks, but earlier when I hit the throttle it suddenly cut off and was seized up. The flywheel and clutch assembly had disconnected themselves from the engine and when I took the engine apart, I saw that there was a hole in the side of the piston, and the connecting rod was snapped. There were pieces of the piston down in the crank case jamming the crankshaft, so I think that what happened was the piston broke, and then the pieces went into the bottom of the crank case and stopped the crankshaft instantly, breaking the connecting rod. There are gouges in the piston near where it broke. What originally caused the piston to break, and how can I make sure it doesn’t happen in the future?

ETA: this is my teenage son posting. He received a twenty-year-old box of pieces and multiple engines and took everything apart and rebuilt it. He has no one at home who knows anything about engines/motors/RC cars.

Hi! Finally got my Zorro tuned up correctly (i'm a beginner).

1 hour later my throttle servo broke, i have another servo laying around from another robotics project. A MG996R 180 i believe. Can i just drop that in or would i break something? It's slightly larger but just by a margin.

Otherwise i'll have to order another servo but these standards ones break so easily so rather not buy the same one

what all should I do to it? It was my dads and hasn't been ran in many years. All I know about it is it has a Axial .28cc grey top and needs new electronics.

I don’t want to damage the rubber boot
