Just do what i do crash in to trees, buildings, Cars, people on occasion :P Joking aside, I would invest in a batt pack. I have a tutorial on the site on how to build one if you don't want to buy or you can use an UBEC and 2s LiPo pack to do the same job. with hindsight I would go with the LiPo...
When i had the LRP engine on my savage with the XL TVPs I ran a 17/47 With the longer wheel base it will be harder to wheely since the weight is further away from the rear wheels ( it acts like a lever).
you need a hammer and saw. Cut off some of the spokes and crack the rim with the hammer. If that doesnt do the trick you need to put them in your food blender with some milk 2 bananas, strawberry and ice. Turn it on high for 5 min then serve cold.

You need to get...
Back in the nitro days we had something called picco star dust. That was what happened to the 2 and 3 speeds when a modded picco .28 got a hold of them. The Flux has more power then that. So all i can say is that you will be grenadeing a bunch of trannys.
I would go with the Flux. It has more power, less mess, less time lost from bashing because of tune issues, heat issues, pull start issues, glow plug issues or many other issues that nitro brings with it. Flux is plug in and bash! It has awesome power and much less hassle compared to nitro. Yes...
That is the first time I'm hearing something like this. The fuel lines are all standard that most likely isnt the problem. it sounds to me like you are bogging down the motor but opening up the HSN. Give it a try by leaning the mix by a turn. It should make the motor run better.
I have had that charger a while back. It wont say how many mAh's are left in the batt. However it should still show the voltage. You should be able to guesstimate how much of the batt you have left and when the charge ends you can just calculate how much mAh you had used up to get a better...
80KKA it shouldn't matter. as long as they are the same mAh and C rating you can run them. Now there would be a problem if you put them up in parallel. But when you have them in series there isn't any problem.
