After installation of of my new 50A/2-4S speedy and the larger capacity battery I took it to the hill for another test flight, just a slight CofG off-balance ended up in total disaster hitting the ground on full power after my first hand launch!
I managed to tape-up considerable damage to the front of the model and had another go with minor shift of the battery backward. Dead calm conditions did not help much, but just managed to clear the ground by few inches for the longest flight so far after scariest launch (vid.) It seem like with the larger capacity battery I will be able to extend my flight time for 3-5 minutes.
I have found even 5 mm shift in CG balance makes a huge difference with these tiny high powered models, making it even more challenging.
All fixed now, hoping for slight head wind for my next flying action.
(Midi Gold nose heavy launch)
New ESC unit with added cooling head seem to work flawlessly.
Nose damage after full power ground impact 13cm stuck in the mud!
