Prop strike on full throttle? or landings?

[wildirishtime]

Well the reason I asked was we were planning to balance the carbs yesterday and I wasn't sure if at full throttle how much worry there was with tipping it over. We tied it off anyway, but wanted to poll the group
in advance, thanks all!

I asked about landing braking 'because' I wouldn't have the guts to stand on the brakes enough to find out where the CG would find itself

good choice to tie down for carb balance . even if you could hold it with the brakes , with that much power there a pretty high risk of something happening while your up at power and inadvertently come off a brake . also , as mentioned before it puts a lot of stress on the rudder system

If I go to full throttle for either a static runup or for takeoff
and hold the brakes, is there ANY chance it can pull it clean over
and have a propstrike?

Second, if I'm coming in on a wheel landing and stomp on the
brakes, can it nose over for a prop strike then? Seems like it would...

Thanks for helping me overcome my worries

Glad I could help.

I dont think that video our relevant to the discussion. While it is always good practice to tie the tail down. You always have good elevator authority when the throttle is in. How do you think he got his tail that high to begin with. That guy raised his tail with the elevator and holding his brakes, in an attempt to minimize drag in his initial roll. To avoid the prop strike he could have released the brakes, let the stick come back, or dumped the flaps. Balancing carbs you should keep the stick back and not attempt a valdez stol competition take off.

In a wheel landing ( I think the video depicts a tail low landing) the tail is flying well and you still have alot of elevator authority. Judicious braking is important at this phase of landing as you can shorten your landing distance considerably while you stil elevator authority.
