What do you have for power in the Oriental? Muffler looks familiar....
I have had several Oriental ARFs over the past few years, all flew great, and power ranged from a Fox .35S ( too small) to the O.S. .46LA ( too big)' and the best flying couple had various O.S. 30- 40 size. (O.S. .35FP just right!)
I am sure you will enjoy both immensely - just make sure the mind doesn't Huff-n-Puff and Blow your plane down!
