Hate those problems[]

10% nitro should run just fine in the .46 AX. Looks like you have may have carburetor problems! Sounds like you maybe fairly new to the hobby, so it might be a good idea to find an old hand at the field to help out if you belong to a club. Be sure to ask questions while the engine is being tuned.

Does the engine lean out when it is adjusted at full throttle, you want to run just a bit on the rich side. If so the bogging coming up from an idle is generally a sign of the low speed adjustment being too rich. It may take a bit of fussing with the low end to get it right. Sounds like maybe things ae a bit rich right about now. Re-adjust the high end once your confident the low end is set correctly.
