Thanks for the tips, advice, and support everyone. I look forward to flying again tommorow, if my schedule will allow it [:@], however, I do have another question. I am currently running low on the 15% "Tower Power" aviation glow fuel and was wondering if it would be alright to use 20% nitro Traxxas "Top Fuel" instead, which I have a gallon of. It says that it is to be used for ground vehicles only, but I have compared the ingredients and they seem to be identical except for the nitro and they sell 20% nitro aviation glow fuel as well. Why would the "Top Fuel" be for ground based vehicles only? Are the surface and aviation glow engines that different? Thanks.
