Since he posted this thread back on 06-21-2019, Steve must have made his decision
as to which "U Can Do" to install his DLE 20 on.
For those folks who are still thinking about mating a 20cc gas engine to a U-CAN-
DO, I can confirm from firsthand experience that the DLE-20RA is an excellent
choice for the U-CAN-DO 60. It is a perfect physical fit, balances with no lead
added and provides very good and lively flight performance with a 17x6 Xoar PJA
prop. I have enjoyed putting lots of mileage on this model since August of 2017
and it goes to the field twice a week. I just flew it yesterday, Sunday 08-04-
2019.
The pictures show my setup.
