Help me out guys- I have a sinking feeling that the Fox 35 I found on Ebay awhile back wont have power to pull an overweight Viking on 60' lines with real "authority". Sig Mfg. offers the above mentioned engine for the enormous sum of $49.99. Yes I would like to pony up to a real engine like Randy's PAs or something with more gravitas but along the way I acquired a number of Foxes. McCoys an Enya, Gh Torp, ST35, all at 35 or less. Did grab a Fox RC in either a 40 or 45. Can't tell for certain(think it's a 45) but the block is huge compare to the stunt 35 Fox. AND I do pay attention to the threads and respect immensely the perspectives of real aces that post here. I realize that the new designs are superior in many ways. A phone call to Sig informed me they still have the Aviastar 46 in CL form. What do you say? Try the Fox or go straight to a larger engine. The Viking weighs 39 ozs w/o motor, tank, wheels etc. Would appreciate some input Thanks
