Curtiss-Wright CW-24B / XP-55 ‘Ascender’ (71″) – Plan


A 71” span sports-scale model ‘pusher’ canard for 4-function R/C and a brushless outrunner. Rescaled to 1:6.8 by Laddie Mikulasko.

Full Description

Designated CW-24B by the Curtis-Wright company, and XP-55 ‘Ascender’ for military purposes, this unusual canard prototype with a rear-mounted pusher engine was the first Curtiss fighter to have tri-undercarriage. Laddie Mikulasko has rescaled it to 71″ (almost 1:7 scale) on the two precision drawn large CAD plans. Construction is all wood and uses 4-function R/C, and an AXI 4120/18 brushless outrunner with a 6S 5000 LiPo for power. At just under 7 lb weight this model is a real eye-catcher.
