Title: ABS plastic moulded aeroplanes Post by: spitfire on November 25, 2010, 11:17:38 PM What is advantage (or disadvantage..?) of ABS molded aeroplanes like thunder tiger ready 40.
Is it crash resistant...? or better than balsa....? Title: Re: ABS plastic moulded aeroplanes Post by: laldenga on November 26, 2010, 09:49:09 AM I think ABS molded aeroplanes are not crash resistant It is difficult to get is repaired in case of crash as compared to balsa made

Balsa models if crashed from 150 feet nose down the ground you cant seperate its elevator and nose :giggle: but My ABS (TT 40) crashed nosedown from more than 150 feet and it took just an hour to reair that with a 3 minute expoxy.

Remember, models are designed to withstand flight loads not crash loads. Let's consider a case where you have two models of same airplane one built of ABS and other of balsa. An ABS model would be heavier than balsa and hence would sustain more damge in a crash due to inertia/potential energy due to heavier mass. Whereas the balsa one being of lighter mass has greater chances of sustaining lesser damage in exactly the same crash. ABS ones have better resistance to handling and hangar damages than balsa ones, easier to clean up/maintain, and definitely look better than an average joe made balsa model |
