Reds 521 Sport 1st tank of break in

[@moralesrcdesigns3784]

This is a great engine for newer drivers. Very responsive, consistent, and it’s not overboard when it comes to power. When it comes to a driver that is more demanding of power, that’s where this engine lacks. I modified my brother’s engine to make more overall power, improve the easiness to tune, and running stability. I also put ceramic bearings in it and will be testing it tomorrow. It was already a good engine before but it didn’t quite have the extra umpf that my brother’s driving style demands. A quick warning with this engine. The rear bearing is very very sensitive to corrosion so don’t be afraid to be generous with the after run oil. You’ll really like this engine, and with proper maintenance, it’ll last you a long time.

Thanks for all the great information! I will put lots of oil in there for after running. Let me know how the improvements go with the motor.

@@johndavidson402 no problem. I’ve already run a couple tanks through the engine to break in the bearings and the engine idles almost smooth as an O.S. engine which is crazy because O.S. has the reputation of the smoothest running engines on the market. I’ve got a base tune on it and will be going to my local track tomorrow to let the engine stretch it’s legs

Thanks I'm Definitely new to nitro. I brought the losi 8ight rtr to learn on and fell in love with it. I raced in the middle 1990's but never could afforded nitro and didn't know anything about nitro beside it could get quite costly. Now that I'm much older I find it harder to drive on the track with depth perception being off, but I do love building rc race cars once again. I learned alot about racing 2 strokes engines in the late 90's to early 2000's and building and tuning and racing real cars. Now I'm back to rc again. But nitro is slightly different learning to tune correctly for each condition. I will gladly except know experience from others like you to help speed up the learning cure. Thanks

@@johndavidson402 no problem man. My brother runs a 521 in his buggy and truggy and my dad runs one so I know my way around the engine pretty well. If you need anything, repinch, engine rebuild, modifying, etc. just lmk. I will say though, the modifying is only worth doing if the engine is in a truggy or your local track is super high traction. The stock engine has perfect power for a buggy on low to medium grip tracks

[@johndavidson402]

Thanks. I run Sumter RC Raceway and Badlands RC in Myrtle Beach. Both are big tracks with grip and alot of amazing drivers there

[@old_and_slow5471]

That sounds like it's going to be a monster on the track. When are you going back to Sumter again? I need to get down there and mess. around with my Kraton, and maybe my RC10GT.

[@johndavidson402]

Thanks I sure hope it's going to be. Maybe next week

@@johndavidson402 I have a birthday party to go to this weekend, then a wedding up in MI the following weekend. I could probably make it to the track sometime in the middle of the week sometime. A lot more free time for me Mon-Fri usually. Won't be back from MI until 7/13 though.

[@johndavidson402]

I can make week days better then weekends

[@johndavidson402]

The earliest I could make it would be July 5th
