[@-RC-Story-]

I like the sound of the engine👍👍👍

[@kings-racing]

It does sound really good with the Hipex 2135. And pleasantly surprised about the performance of this engine. Thanks for watching.

[@-RC-Story-]

[@kings-racing]

Very nice day indeed. Love those practice sessions. Thanks brother. Definitely pleasantly surprised by the engine. Runs really good.

[@NitroFreak]

@@kings-racing awsome little engine how much was it ?

[@kings-racing]

€ 172,- ....very curious about the lifespan. If it lasts this is a perfect budget racing engine.

[@kings-racing]

Thanks Crazy Dad 🤘 Wooo. Just subbed to your new channel. Keep having fun brother 👊

[@jukkaovaskainen]

OS is good and quality engine even in it's cheap models 👍

[@kings-racing]

The most basic OS engine and I'm pleasantly surprised by the way this engine runs. Really curious about the lifespan. I don't know if the hardness of the crank and the alloy of the piston and sleeve is very different. Time will tell Appreciate the comment buddy 👊

[@TastyBRC]

Almost a race engine. Driving was awsome with the electric buggy

[@kings-racing]

Thanks buddy. I'm pleasantly surprised. You can definitely race this engine. Perhaps a few light modifications and she will run even better. I'm also curious about the lifespan. If that's good this would be a perfect cheap race engine. Love these practice sessions, trying to stay close to each other.

[@ThompsonRc]

You got it running great kings

[@kings-racing]

Thanks Thompson 👊

[@MrLilChilly]

Looks like a pretty strong engine. Nice video bro!💯🫡

[@kings-racing]

Thanks bro👊. She runs really good. The most cheap basic os engine, but definitely good for racing

[@RCWright]

Nice Kings! That has some nice power and great driving 😁

[@kings-racing]

Thanks Robert. The most cheap.os .21 offroad engine runs very good. Very curious about the lifespan. If it remains good for many gallons, this definitely is a perfect budget racing engine. Appreciate the comment brother👊

[@a2rc]

Looks like a great day at the track 🩷 - Let us know when you can give an update on the dyno situation Thanks for the vid 💯

[@kings-racing]

It sure was. The temperature was great. Nice and sunny. Love those practice sessions. Did you see the vid i uploaded and took down? The company hasn't replied on my third email yet. I'm gonna give them some time. Already ordered some parts and got some in to modify the dyno so working on that. There will be a updated vid on the dyno. Thanks for watching buddy 👊

[@a2rc]

@@kings-racing I appreciate the update Kings. I unfortunately did not get to see it before you took it down. I would like to watch it some how but, Tasty and I did talk about it on the side for a little bit It’s been rainy and real life has kept me really busy over the past few weeks. I hope to get back to some hobby stuff soon. I get to live vicariously through everyone in the mean time 😋

[@a2rc]

@@kings-racing I just watched and left a comment. Thank you for letting me see it. Looking forward to your updates 💜

[@kings-racing]

No problem buddy. Yes, it really sucks to have destroyed a engine. Working on the modifications. The company said to throttle down and pull the plate at the same time. There is absolutely no time for that. As soon as you close the throttle the engine is toast. Imo it's also very dangerous when the gears spinning at 40K rpm with the force of the flywheel behind it. There is another youtuber who was dynoing the lrp. The exact same thing happened. kzbin.info/www/bejne/q2PMiXuHg96eeNUsi=fFfDrzb9m-pasKjI At 19.48 Now i know why this guy hasn't been uploading. Pretty sure he destroyed that lrp too. Probably will publish this vid again as episode one. Not sure yet. Anyway, Thanks for the comment. There sure will be a review from me.

[@tonysands2837]

That’s on rails bro nice driving skills bro awesome job bro love watching your videos keep it up 🤜🇦🇺💯🔥💥

[@kings-racing]

Thanks bro👊. Actually my shocks were to soft due the temperature so had a bit of a struggle with that. This engine is pretty good Appreciate the comment brother 👍👊

[@robs_rc_cars]

Thanks brother 👊

[@haywirerc]

OS power!!!!

[@kings-racing]

This is a very basic engine, but i'm pleasantly surprised by the way she performs.

[@Serialcrasher]

Nice 👍 did you notice a big difference between 25% and 16% nitro ? I have heard that 25% might be soon « forbidden » in some countries. For the time being I still find 25% nitro fuel here 😀🇨🇭👍⛽️

[@kings-racing]

Bonjour Serial. The difference is not really big, but definitely some more power with the 25%. It already is forbidden, but it's still around. If they follow the rules, you can only buy it with a permit. I still have a nice stock😅 Thanks for watching buddy 👊

[@ZingZingNZ]

We run 30% in New Zealand

[@davidgolf7562]

How does it compare to the K303L I know you love?

[@kings-racing]

The K303L is definitely stronger, but guess we gonna find out what the exact difference is after a dyno test with both engines

[@davidgolf7562]

@@kings-racing yes exciting, as long as the test parameters are identical the dyno doesn’t lie 😁 will be great to see

[@kings-racing]

​@@davidgolf7562 yes exactly. I will need to test back to back for keeping the parameters the same.

[@davidgolf7562]

PS is the K303L still going strong?

[@kings-racing]

Yes, still going strong. Just got it apart to check and clean it for the next race.

[@jonpye8655]

What is the fuel mileage like on 25%

[@kings-racing]

I haven't timed a tank yet. But since the total crank timing is not very high, think the mileage is pretty good.
