ok i read up alot on that subject thank you i will order it from towerhobbies asap. you said that mounting the engine would create more problems then leaving it in the truck what other problems?the reason i want to also mount it out of the truck is that i want the engine to the point of that every time i want to use it it starts right up like my ct5 that was sitting for months and it started right up with like two pulls of the pull start. thats how i want my gst 7.7 to be.
