The engine just came up for sale here in Germany, for a half-way acceptable price(though still %25 more than an Alpha S852 - €200 vs. €150...)
I run both the Alpha F850 and A852 plus the Arrow. The Alphas do have more power and better runtimes. Comparing the S852 to the Arrow though isnt exactly fair to the Arrow. The S852 is a 5 port engine and the Arrow is a 3 Port. Now if you compare Alphas RTR 3 Port to the Arrow they are really close. Both engines are reliable and easy to tune. The Alphas do have alot more mechanical pinch than the Arrow making for a more difficult break in. Though thats nothing a heat gun doesnt fix.
Over all....
Pure power output will go to the Alpha...
Break in will go to the Arrow for the less amount of pinch
Runtimes I have to put to the Alpha
Both the Alpha and Arrow tune easily
Lifespan is TBD. My F850 and Arrow are at 3 gallons and my A852 is at 1 gallon.
