A friend of mine has a big Moki 2.10 in one of his planes. I met him the other day coming out of our local hobby shop carrying a gallon of glow fuel on each arm. If you like the oily mess and can afford the fuel-- by all means go with a Moki. Don't get the idea that I dislike glow, but I believe they have thier place. 7 out of 8 of my planes are powered with glow engines but in the .46/61 size range. Also have a OS .91 four stroke on the UPROAR pictured to the left and love it.
