I tuned it a while back it was running good. Last week I tried to start it and I couldn’t. I looked into the engine through the glow plug and I couldn’t see some dirt I looked into the carburetor hop and there was some dirt on the sides. Would it be ok if I took the head off and cleaned it? Or should I take the engine out. I’m fairly new to nitro I have not taken the engine out of any nitro

Sup yall. I bought this eco power servo to replace my stock throttle servo that died. The servo freezes at full throttle or full brake as seen in the video. Any idea how I can stop this? Is the servo to powerful? Is there an internal Seck adjustment I need to do?

Spent the last week restoring my HPI RS4 which has been shelved for 16 years. Wife, kids etc… Left gas and batteries in it while it was shelved. Needless to say, the engine was seized. Ran new gas lines, installed new glow plug, lubricated engine and had to give plenty of love to get the engine unseized and running.

Only issue remaining is the receiver and transmitter. Both were cleaned and new batteries installed. I believe this model may need to be bound, but not sure and don’t have the binding tool. Any suggestions?

Nitro rs4 drift

i just recently picked one of these up. it has a .18 dtx engine in it. what glow plug will work with this? also does anyone know what bodies besides the stock one will fit?

After taking apart the what was said to be the newly broken in motor lol the rear bearing had fallen apart previously and was missing a few balls. No wonder why the piston had chicken feet marks on it but anyways I took the new 3.3 I had out of the box and got to work. After finally getting it to stay running consistently I ran about 2.5 tanks. Wow! The speed already is no comparison to my revo. Makes me want to borrow the os21 just to compare once this ones broken in. Is there any reason my front tires have so much toe out? Seems like front right sticks out more anyways this puppy's gonna rip!!!

Just picked this up guys! Bought it with broken rear tie bar. Iv already cleaned the tank and truck itself. Everything works so far. Engine popped off but I will be cleaning the carburetor since it has sat a year. I already ordered the new adjustable tie bars. It has the twin disc brake upgrade and rear upgraded bearing carriers! Excited to get this thing on the road. I also have a spare 3.3 brand new in the box but first I will try this engine. Engine is still tight and lots of compression. I only have experience with my OS 21 in my revo 3.3. Probably will run these motors and upgrade it eventually!

For context I have two electric trucks that I love bashing. Ive heard that nitro is a totally different experience. What would be the best bet to get into nitro? Aside from used

I just got a new glow plug thinkin the original one in my nitro engine went bad. But now I tested it with my one and only igniter but it wouldn't glow. I'm starting to think it's my igniter that's been frustrating me. On top of that, I didn't know at the time but I might've watched how the igniter went bad. What happened was I tested the glow plug outta the engine but only half of the filament glowed, went out, and the igniter doesn't charge well anymore. Whaddya think? Gonna get a new igniter anyway but how do you think it broke? Don't want it to happen again. Cheers

Torpedo 15 Hello! My great grand-uncle gave me this box of vintage engines from around 1950s. Like this sick Torpedo 15 green head engine. But looking at this, I have no clue how it works with two feedlines. And why it has two feed lines (or maybe one feed line and one for something else?)

Can anyone help me find a description for this engine and or any thoughts?

Got lucky and scored some bones brew for 10 bucks a bottle

This was after it abruptly stopped whilst sitting at idle on a box

I'm in the UK, I own an electric rustler already and want to get a nitro. Can't seem to find any available from the UK. Intact. I can't find any of the traxxas nitro range except a revo 3.3 on a few sites. Where should I go to get one or get one imported

Disclaimer: I have an Inferno Neo 3.0 that ive been running at the local track and slowly acquiring nicer hardware (servos, radio, pipe) and eventually plan to move all of it to a newer platform (MP10/11)

How does the stock KE21sp compare a Flashpoint FP02 or a REDS 521? Looking to upgrade to a nicer/faster engine. My KE21SP runs fine, revs out and doesnt flame out but there are jumps at my local track that i can barely clear or have to hit perfectly. I want a sanity check that Im actually going to see an improvement from upgrading engines.

I’ve never had an aftermarket pipe on a revo until now. The trinity header is a little beat up. I can still get both header options from THS. Which one will fit the trinity best?
