mr heintz replied when I asked about using a vw eng on that plane that he didn't recommend it. doesnt mean you cant i guess. that plane is the one i first had the hots for, but due to cost i wanted to use an inexpensive eng. thats why ive gone with the sonerai even though its the opposite of the 701. good luck. ive bee told that the subaru is a good candidate for the 701 though (by the co. that sells them) about $7000.
