They are cheap, but there is an art to the care and feeding of Foxes that not all of us want to deal with. The LA is pretty much a plug and play piece with a same or more power.
There is? Coulda fooled me. I mean the older ones were a bear to break in, but the modern ones break in fairly fast. The needle isn't that great, but inexpensive to replace it with a Supertigre type. But it works well enough that you can wait till you crash inverted and break it off!
But other than that just use 5 or 10% nitro with at least 25% castor oil a 10-5 or 10- 6 prop and run at a four cycle mixture.
