I'm having some problems Tuning the TRX .15 in my T-Maxx, My temp gun disappeared from my luggage while moving so I'm having to do this without one.

Climate: Currently between mid 20's & mid 30's Fahrenheit & Currently snowing.
Fuel: Blue Thunder 10%

Symptoms: Good Low end, but Engine Bogs and usually dies at half throttle or more once Engine is warmed up.
(Note: I am not using any tinfoil on the head atm)

What I need to know: One or both of 2 things, With the Bogging should I richen or Lean out the HSN, and What settings for this kind of weather should I use (turns from closed) on both the HSN & LSN?

I'm wanting to take my Maxx out in the snow tomorrow & would be grateful if I can get this figured out by or before then

Thanks!

Status: offline 		correct me if im wrong people but 30 degrees tempatures isnt exactally the best weather to be running a rc in...what you should do is allow the engine to heat up for around 3 mins because of the tempatures your in. Then run it; tune it when its running at a good tempature that way the climate shouldnt be a problem the reason that it dies at half throtle is that its too lean, and needs to be richened u need to understand that lean means less fuel and rich means more to the engine when u full throttle and it bogs its because your engine is sucking on air rather than fuel, and it dies because its fuel is cut off because you consume all u have to offer. u have to make it "richer" that way the engine is running on gas rather than fumes.

I yeah I know sub 30F temps arent the best, but I dont have a lot of choice in the matter since I live here in Idaho.

I figure If i put some foil around about half the head that it should keep the engine temps up to acceptable levels, or am I wrong?

Status: offline 		Man TRX .15's are sure FUBAR'd had to ritchen the LSN to fix what ritchening the HSN should have...

Cant wait untill I can afford a New OS .18TM & can scrap the TRX POS...
