Trying to identify OS.21


Recommended Posts

As per the title really...

I bought an LRP S8 Rebel TX that needed some tlc and putting back together. From what I've read so far, it should have a .28 engine?  Yet this one came with an OS .21 engine just sitting on the chassis. 

Now that doesn't overly bother me, I've got it all built up and started (even managed to find the correct early pull start with 3 bolt configuration!), but I'm struggling to find info on what version of engine it actually is - I can't find anything other than a sticker with glow racing on one side of the block and OS 21 on a sticker on the opposite side. 

 

The carb also only has a glow racing sticker on the body, nothing else stamped in it 🤷🏻‍♂️

 

I've taken a load of pics, hoping someone can help me identify it and where I can find the specs for it!

So as no one has commented, I assume no one knows which .21 variant this is?

 

So next question is, which engine would be a suitable replacement that would fit? 

Originally the S8 Rebel would have had an LRP z.28 engine, but that's very pricey just for a basher truck! Can anyone recommend an engine that will fit that won't break the bank?

Thanks!

Nitro is a bit niche these days. A truggy is usually best with a 28 engine as it is heavier than a buggy. Today the Force 28 engine is probably the best value. Most engines will fit that mount.

Thanks bud, I'll see if I can find a Force one that's suitable, but I'm not sure which crankshaft version is correct 🤔
