--Under Construction--
This page contains tips on converting the Mamba to Electric.
The Mamba was designed with electric conversion in mind. The aircraft has designed in a forward hatch that makes access to batteries and connectors easy. The 'fuel tank tray' is located to work as a basis for a battery mount.
Flight time is about 4-4.5 minutes with proper throttle management and a good reserve. Make first flights about 2/3 of this time and check remaining capacity while breaking in and balancing your packs.
The primary conversion is STRENGTHENING the 'fuel tank tray' to work as a 'battery tray'.
Power System (as demonstrated by Flex innovations)
- E-Flite 360 - 180kv Motor(EFLM4360A)
http://www.horizonhobby.com/power-360-brushless-outrunner-motor--180kv-eflm4360a
- 70mm total motor standoffs
- Potenza 5000 6S 60C batteries were used (Two in series (12S))
- Castle 160HV ESC
- Mejzlik 25 x 12 Prop
The chosen motor uses the same bolt pattern (and firewall hole locations as a DA Gas Engine making mounting easy. The Prop bolt pattern also matches the DA 4 bolt pattern.
We reinforced the battery tray as follows (thin and medium CA Glue was used for all)
- Approximately 1/2 wide strips of Carbon plate (~.080" thick) was used in two places to reinforce the structure under that tray. It was wrapped to the structure with carbon chord (toe).
- At the aft end of the battery tray oriented vertically. Carbon chord wraps used.
- At the middle of the tray oriented flat against the tray. Carbon chord wraps used.
- Two strips of Carbon plate were laminated to the top of the tray to stiffen it and to apply velcro to.
- The aft edge of the plates were thinned to allow carbon chord wraps to be applied to prevent delamination.
- A hole were made in the front center of each plate, and the plated was wrapped to the existing structure with carbon chord to prevent delamination.
