Every now and then my revo dies when I hit 2nd gear and nothing I have tried has fixed it. I just had it tuned and have only had it for about 2 months. Has only started doing it the last week. If anyone has any sort of solution or idea of what is causing this would be much appreciated. I am new to the RC world and hope for any help at all.
99% of the time, bogging/dying/flame out, just before or after the shift change is due to a lean HSN.
By “I just had it tuned” I presume you mean by someone else? A nitro engine will often need to be tuned on a daily basis or even hourly if the weather conditions change enough.
No slipper/tall gearing/power = broken parts.
