VMA-D260X Dornier DO27 45-61 ARF ECS - Engine & Prop Size - Recommendations

This supplementary information applies to manuals with a copyright date of 20030321 (see back cover). Manuals having later copyright dates may already reflect this supplementary information.

This model flies well on a .46 size two stroke engine such as the VMAX 46PRO or a .52 size two stroke engine such as the VMAX 52PRO. We suggest using a larger diameter lower pitch prop that you might have used on another model with a similar sized engine. Check your engine manual and select a prop that is at the maximum diameter in the recommended range of props for your engine. We have found that a .46 works well on this model with an 11 x 5 or 12 x 4 prop. The idea here is to locate the thrust out beyond the edge of the fuselage and cowl. A larger diameter prop helps accomplish this.
