Rather interesting bungee launch with one of my smallest 30mm EDF "Alpha". Bit of a handful to fly, Ailerons were slight off the trim rolling badly left.

One handed sling shot release.

Quick correction required after KE!

After further mods the catapults are piece of cake with these little handfuls, but landings are another story! I might try to fit a very short thrust tubes to give it a slight down thrust to make the current very nose heavy model back to neutral CofG, but the next build I will definitelly reset the outlets some 3 degree downward, but before I get into 3rd. one, I'll have to write-off one of these, it's only matter of time, but only God knows when, LOL. Another run on doom&gloom day.

Not so easy today!!! The scariest sling launch ever!!! I can't believe the model is still in one piece after the horrendous launch!!! Took out my 90mm "Hawk" just to discharge large 6S/9000mA lipo. Couldn't fitt it further back so the model was extremely nose heavy despite fitting 100g aft weight for counter balance. 500 grams heavier than my usual 5Ah packs, I thought it may struggle a bit getting airborne but not this bad! Should have brought my heavier duty cord as I didn't pull it hard enough for launch, landing skids getting bit stuck in wet sand during launch with very little positive AOA. It was a U turn battle to keep it up in KE's before managed to get safe flying speed.
You have never seen anything like it after I load the footage! LOL.

Extreme nose heavy loaded Hawk sling launch.

1/2 a kilo heavier than my norm.
