I disagree. As a newbie who is flying and crashing an aerobird and a slo -v. The slo-v is slow, but it is too delicate. The slowest nose crash from a height of 6', or a nose tumble when it comes along the grass and the gear catches, and the propeller shaft bends, and or the boom in front of the engine breaks. This then requires a full rebuild. Too delicate.

The aerobird challenger has been very forgiving. My friend and I both who knew nothing have taught ourselves how to fly, and occasionally land. Well we always land, but the rate of deceleration is sometimes extreme.

The fuselages of our birds look like they are from Iraq. We have replaced a few wings and rubber bands, and that is it. This despite direct assaults on trees, roads, a neighbors house, etc.
