should say face plant.. Wiith bush wheels and extended gear. plus 3 only. Not extended forward.
how does the tendency to face plant under heavy braking compare to standard gear and 8.5s?
1. Higher
2. Same
3. Lower
Your opinion please.
How so?The physics favor the longer gear and bigger tires
How so?
While from experience I'd agree when the tail is down but with the tail up and get on the brakes it would seem that with that significantly longer moment arm (taller tire and longer gear) is now acting against you (get past the top of the arc and Gravity is no longer your friend) as the "lantern plant" begins to develop but that may be offset by the apparent reduced breaking effect (equal breaking energy available/surface area adjusted by the tire difference in friction coeficient). Hum, I'll pose this to the budding aeronautical engineer in the family...
... Once you get a prop or two you will get the hang of it.......
Yep, completely agree. My comment assumed 3-point attitude. I don't do that tail-high-stopping-magic so didn't even think about it.It depends. The distance between the ground (the point of friction) and the CG is longer with bigger tires. As stated above, when the tail is on the ground, there is more weight on the tail and less nose-over tendency. When the tail is up, say more less horizontal, the CG is nearly over the wheels (little tail-down force) and the longer arm works to make it easier to nose over. So, if you brake hard enough to raise the tail up to horizontal, it will be a lot easier to keep on going over. If you're slow when you do this, there is little airflow over the tail to counter it.
I have noticed more DAMAGE, bent tubes under boot cowl/engine mount damage with long gear & big tires, instead of just flipping over without much damage
.. did the big tires and long gear actually create the damage due to the arm?
Yep, a longer handle on the same hammer with the same swing will do more damage!
