was the humidity high ?

So barring that you have a rich tune, weak glowplug or fading engine ( All the basics )... if the engines flames more when the humidity is high it may be a sign that your fuel has some water contamination in it... Try a fresh gallon of fuel, or a different fuel and see if the issue goes away..Sometimes a fuel can absorb moisture and start to lose stability, it may be hard to spot as the effects can be subtle, but if you see a rapid loss of idle quality and stability when the humidity is high its likely your fuel... the extra humidity further contaminates an already contaminated combustion..... Anyways hard to know for sure without having the fuel lab tested... But its easy enough to try a different gallon of fuel and see if the issues resolves itself... Of course barring the basics like tune,plug and compression and engine damage fuel is a often overlooked variable...

The flame outs have been happening since the day I built it. I will try leaning out the bottom and try that. But the motor runs perfect and has a perfect Idle.i was thinking it was more of a fuel tank issue.

you are getting a shot of extra fuel during pitstop but your engine isn't stable enough to handle it without stalling out.. When the tank lid closes a extra shot of fuel enters the lines and is drowning the glowplug and stalling the engine out...All tanks will do this. issue is the engine can't burn off the extra fuel and recover.. As I say the signs of water in the fuel can be subtle and will start showing at places like pitstops where the engine is most vulnerable to flameouts..... But yes....obviously if your too rich or your plug too cold these issues will happen....same if the engine is starting to lose compression, or has a damaged bearing.....

Mo,

Just so I understand correctly. On your set up its says 600 front and 500 rear for stock oil. That would equate to 50 front and 40 rear with the losi oils. Is that correct? Bc I read somewhere that the splits should be no more than 5.

I did get a chance to drive the car this weekend and i was really impressed by it. Mo's set up seem to be money however I am concern about shock oils. the temps were I run is 85 to 95 degrees. Should I base my shocks oils based on temps?

The two things that jumped out to me was the jumping and the acceleration. Initially this car feels like a cross between my D812 and the Mp9. I dont want to speak to soon but after running two tanks of fuel it has the corner speed and jumping of the MP9 and the streering and stability of the HB. Throwing this car in the mix should be interesting.

600 front and 500 rear work really in that temp range (same temps where I'm running right now) with the 10 hole kit pistons as long as the track is fairly smooth.

Edit: I'm currently running AE 47.5wt (613cst) front and AE 40wt rear (500cst) so you're probably in the ballpark with the Losi oils.

Had a great time racing down at Revelation last night. They plan on racing the first Tuesday of each month and the third Saturday of each month right now.

During the first qual I laid down some decent laps and was only off of Drake's fast lap (fastest Pro in attendance) by .8 sec which really surprised me. Says a lot for the buggy and Mo's setup! During the break, I went down to 45wt front and 37.5wt rear and that ended up working out nicely for the second qualifier; I was able to carry some more speed through the rough sections and the Catapults were still hooking up really good.

Ended up with the TQ but they inverted the field for the main so I started at the back anyways It cooled off almost 20° for the main so I decided to put the soft Cubez on (was running medium Catapults) and that turned out to be a huge mistake! They put a very small amount of water down which promptly turned into a nice dust on the surface of the track and it was like driving on ice for the entire main. Ended up having a really fun battle for the top spot (1.5 seconds separating 1st through 3rd) with two other drivers but was able to take the victory in the end.

Did have some transponder issues during the first two qualifiers that I need to do some more investigating on but other than that, buggy is doing great!

Sounds like a good outing to me. Good job. Sounded like fun.

Has anyone tried to fit Avid LRC inserts (initially for AE8.2) into the Tekno D-plate? Tekno LRC plate 'outofstock' everywhere, but i definitely want to try Mo's setup and have pair of Avid inserts.

No idea on the Avid part but Tower has them in stock.

Mo on your set up the diff oils are 5-5-4. What should I expect if I went to 5-5-2. The reason I ask is bc getting on the straight away the car wants to kick out side to side. I have to wait for it to settle before appying full throttle. Also theres a spot on my track thats like a table top sweeper where when I land and get on throttle it wants to overstreer as describe a few pages back. In other words the car will do a spin out or 180 if I get on throttle too soon. I have to baby it in that section.

I'm not Mo but are you running the new black diff washers?

No dont have them yet. I will have them on friday.

doesn't sound like a set up issue to be honest. I don't think many people squeeze the trigger harder than I do and its pretty stable. I guess the first thing I would have you check is make sure you have black diff shims in and also make sure your clutch is fairly fresh. I went to the losi clutch cause I felt the stock clutch gets pretty grabby when it wears in.

but to answer your question the 2 in the rear will be less stable than the 4. it will have more initial traction and overall steering but break loose more suddenly. and the same for corner exit. if your an easy on the gas driver then you can get away with thinner diffs but for more all around consistent handling and more on power forward traction the 4 is better.

as Madweazl stated the oils will be fine for those temps. and I built a buddys car with the AE 47.5 and 40 and it felt the same as mine did on the track so either 45 or 50 front and 40 rear will be fine

Awesome Thanks. I run your complete set up. I have at least 10 different clutches but not the losi, so i purchased the losi pre-built one. Love the acceleration on this car.
