REEDY .21 Nitro Engine
#406
the best thing for keeping the motor hot while at idle, is to use a 1/10 scale foam tire insert and put it around the head. Fits snug and is a hell of a lot easier than wrapping in tin foil.
I did what Brandon Powell did, but only idled 4 tanks, then drove it rich but WITH the foam on the head and it stayed around 240. After 4 tanks of that, start rae tune.
I have 5 gallons on mine and it feels like it did after 2 gallons.

Ran the Reedy alittle bit more and this time i had a re11 losi pipe on (2050 copy) and it was much more top end then the 053mr pipe i had on. It also got better fuel mileage and i had to lean it up about 2 hours on the HSN. Has alot more noticeable top end and was temping around 215-230. Has one gallon through it so far and just sealed the back plate. Rod is snug and fine.
Pics arent the best i took them on my iphone.

that' what I was thinking, lol.
RBFIVE- I did a back to back pipe comparison at the track on Thursday, where I tested the re-11 and the 2035 within 20 minutes of each other same track, weather, etc..
They did tune different, like you said I noticed I had to lean the re11 out more, but to my surprise I got 34 seconds more run time with the 2035 and the motor ran 10 degrees cooler with the 2035.
As for the top end, I tried it because I figured it would wake the top up, but to be 100% honest, I couldn't tell the difference in speed, little different pitch to the motor, but with higher temps and lower run times, the re11 or 2050 just didn't cut it. I'll be sticking with the 2035 until I get my hands on something else to test. I ordered a TT2039 to try out, it looks like the 2035 but a little shorter.

I love the way the reedy looks and runs on the track. And for the price tag you also can't go wrong. Im just a little iffy on how hot they run. i like to run my motor a little bit cooler. Around 200-210 since i race on a smaller track there is really no point to get the temps real high. I also have been seeing that a lot of guys are having trouble with the tuning.

You are the first person I have seen run that engine at those temps. How was the performance of it those temps? If it ran good at those temps, it would be a motor I would consider now. I liked the way it looks on paper, but just to see so many running at those high temps is something I am not to keen to.

this reedy engine looks very impressive. only thing is i know there is a bearing issue on the inside of the engine i just think that if i get it i will have a lot of bearing and reliability issues. also do you think this will be a 10 gallon engine before rebuild. let me know

I haven't tried a 2035 yet but my buddy did and it wasn't much diff then the 2053. The re11 gives this motor a bit more up top.
From my experience when your running your engine hotter your just leaning it out to get more power then the engine wants to make. My engine runs great at 215-230

by no means am i any sort of engine tuning guru but, I believe that you should use temps as a guideline. I tune for smoke and performance. I am quite lucky to have about a million years of rc experience pitting with me as well.
I have seen my reedy run anywhere from 225 to 260 depending on the weather conditions. I have not once seen a lack of smoke from the pipe so I am happy.
