Savage X 4.6 Tuning issues

       Remove this ad - become a site supporter!
Just thought I'd post this in case anyone else has an issue with breaking in a new Savage X.

I picked up my Savage X 4.6 on Thursday and started the break in process last night. What a pain is the *!

My bud also picked up the exact same one and had no issues what so ever. HPI states that factory defaults for the carb is having the adjustment screws flush with the fixture. That is how my friends is. Mine on the otherhand was way to rich on this setting. I had to turn the HS screw in 1.5 turns and the LS screw in 1 full turn before I could get it to run for any length of time. Not to mention the rapid depletion of fuel......

Also, his brakes were almost bang on but mine was not even set at all!

Now that it is set up right....all is good

I had a difficult time gettting mine to start out of the box (SAV X SS), then during break-in a piece of the lower skirt on the piston head came off and was banging around inside. I knew something was wrong because the pull start wouldn't function properly. Once I pulled apart the engine and took out the piece of the piston head, the thing ran fine. Lots of pinch on those engines though and is fairly hard on the pull start at first until they get broken in.

Hard To Start

Well from all the times of starting big block engines ..the pinch is so tight you should use a hair dryer to heat up the engine to at least 150 degrees or more then pull your pull starter,,,I have found after about 6 to 7 tanks of fuel it will start to loosen up..Really no matter the brand of RC you have.After 1 gal you can use a roto starter if you wish..Before that you will have a hard time starting if going to use roto starter..I have always used a hair dryer to preheat a new engine..
Always check your factory setting first ...after some fine tuning it will run great..When ever you have a problem or diffacult to start reset your needles to factory settings..not counting a flooded engine or glow plug bad or the igniter battery dead..Hope this will help you out..
OH Yeah if you have 1/2 fuel tank lean problems you need to install a oneway check valve in exhaust line to fuel tank....

My Savage XL was almost 100% out of the box

I picked up my Savage XL last week and out of the box I found the carb was set for break-in but the brakes were not setup correctly. The brakes wouldn't engage until the carb was almost closed which caused the engine to quit.

I also found that some of the screws on the chassis and steering needed to be tightened which reduced play between the parts quite a bit.

I replaced the stock servos with beefier units that I already had and swapped out the radio for a 2.4Ghz unit. With the servo swap came new servo arms and I also added a OFNA linkage kit which I find smoother than the stock unit.

Overall I'm quite pleased with the build quality and will over time I'll plan to upgrade various components to improve performance.

Savage X k4.6

I had mine two days before starting pin spring broke(part # 1433) and went up into the cylinder and scored it bad Called HPI they said send it to us and we will look at it. A month later they sent me my FIXED motor, It was worth the wait, POWER is GREAT compared to my 2.5R REVO which i still like just no wheelies(Like the Savage).
