A jet engine will not fit in any 1:16th scale tank. It is hard enough to fit what we have in them as is.<div> There are not many choices as far as an Abrams goes. There is the Hobby Engine but that is more along the Toy grade route. </div><div>HL's are better but still not hobby grade without a good deal of upgrades.</div><div> If you have to have an Abrams and can afford it you really only have the Chunwai like Yellowshaker has mentioned.</div><div>If you just want to get started in the RC Tank hobby you need to understand what you want out of the tank.</div><div>If you want a great deal of realism and build quality go with the Tamiya.</div><div>If you have to have the top of the line Abrams go with the Chunwai.</div><div>If you just want to get your feet wet go with the HL but they dont have an Abrams in 1:16th scale.</div><div>For the Jet set up you would most likely need to go with a 1:6th scale at the minimum</div><div>Even though the jet engines in hobby scales have enough thrust to fly a plane that does not mean they have enough motive power to drive a scaled ground vehicle like a tank that will weigh up to and may be more than 100 pounds in the 1:6th scale. They may just not have enough thrust, I dont know.</div><div>Just some things to consider. Neat idea though.</div>
