well i got her back out today, and she stills seems like she's going strong

thank goodness LOL i've only got a gallon and a quart burned through it so far. this is my first nitro so i'm just worried about every little thing i guess. all i want is for this engine to last the rest of the warm weather LOL then when it gets closer to spring if i've been to ruff on it and it has lost all of its compression i'll order a new one. i didn't really realize how sensitive these motors where till after i done ordered mine and was reading a little more in depth about it.
also i ordered a bigger set of back tires for my jato, because the ones that came on it wore out after about 2 days [:@] and so i've had to adjust it to shift into 2nd gear, but i think i have it shifting to soon now??? if it shifts too soon will it cut down on its top speed??? because it seems like it boggs down after it shifts to 2nd in grass, or is it just because its in grass???and thanks for all of yalls help
