    That’s a great deal with Revo and engine

    My 21TM ran warm for the first gallon or so and was kind of fussy for tune. After 1.5-2 gallons, the only issue was finding the time to run it. lol! With a little tweak at the start of a bash session for the ambient temps/humidity, it would run fine all day.
    I haven't fired up a nitro in 3 years. I have a big block revo and a 21TM revo. The only two nitro's I have left. They just sit on the shelf.
    The power of the 21TM is more noticeable in the revo vs the slayer. I had my big block revo as a slayer when I bought it and it only had a 2.5R in it I believe, was a short silver chassis. It was plenty of power for the smaller tires. I ran 1/8th buggy tires on it. I just got tired of traction rolling the thing and it landing jumps like a brick. Didn't really have anywhere to run a slayer. Either flat ground (which was boring for me), or big jumps. It's now a 3.3 chassis with an LRP28S3 in it.

    Think of the middle needle being the transfer point between HSN and lsn as you adjust the MSN you will notice different shift characteristics

      And it also helps control the overall temp of engine

    The reason why the 3.3 is more forgiving is beacuse of the head clearence they run such low compression compar3d the the os its not even funny. They did that so people had a chance to learn tuning before destroying the engine
