| Jul 28 at 19:14 | comment | added | Sairext Irkaris | that's one of the problems I have with the design I chose, currently I'm still trying to fine a way to go around it, with the battery I have I can supply my engine 15kW or around 20hp which is sufficient for the 2 engines at max power. A rule of thumb I've heard is 100W/kg, so mine may not be enough. It's the challenge to go with this design and I'll see what I can do to overcome that. For now I'll clear the legal part first, then I'll try to fix the problem later after I know it's possible to get a airworthiness licence. thank you for the advice. | |

| Jul 28 at 6:08 | comment | added | Sairext Irkaris | Thanks for the advice about the propulsion system, but I already decided to follow my dream project so it will resemble a fighter jet, the F-117N seahawk. the turbofan I use can be put internally, it provides enough thrust for a comfortable level flight and ~1m/s climb. with this design it will not be efficient as the L/D ratio is 15.22 which is quite low mainly due to the swept wings for aestetic which need surface area to conpensate. but it fits my requirements as I only fly local flight and want to experience flying feeling, so I'm fine with that efficiency if it looks like what I dream of. | |
