hi, i am setting up a smoke system on a .46tt. i have already read the how to do smoke on rcunvierse. By the way thanks to whoever did that, it helped me out alot. Im going to use [link=http://sonictronics.com/xcart/customer/product.php?productid=16406&cat=414&page=1]this smoke pump.[/link] However i am not sure to go with this pump, does anyone have anysugestions? for the part of heating the oil, i am goign to wrap coper tubing around the cooling head of the engine, this will heat the smoke however it will not take away any heat from the muffler. (Like the smoke article said)for the tank i think i am going to use wither a 6oz or 8 oz tank. This is mainly because my fuel tank is 10oz so i think i should be under that. the oil will be MDW Aviation Super Dri Smoke Oil Gallon. ( i have heard good things about it). I know in the smoke ariticle it suggested using a flow resrictor. I am thinking, i have an extra fuel adjuster from my nexstar so is it possible to use that. any suggestions on the pump would be great, also the plane that i am putting this in is a four star. one last question do balance the plane with fuel smoke fuel along with normal fuel or do u just balnce it with the normal fule tank fuel. thanks.
