BobCat elev. throw
Hi Guys
I am just doing the final touches ( you know the last 5 % that takes 90 % of your time ) on my RAM 500 powered BobCat and came across a question. I realize that Tony is using 20 degrees throw for elevator travel IN EACH DIRECTION. My question is to those that are currently flying BobCats what is the max amount of throw for the elevator you are using for UP and for down. In the BV manual it says 1 3/4 " for each way ? I would think that would be a little extreme.
TIA
Dean

Elev throw
I'm have 10, 15 and 20 degrees in each direction, on low, medium and high rates. I'm also running expo (different amount on each rate, with a max of 20%).
I also run a little less expo on the DOWN elevator, mostly to reduce the amount of stick I use in the inverted. (I think mine may still be a little nose-heavy, but I'm changing that just a teeny bit at a time.
Regs,
Gordon

For you guys who are not set-up to measure it in degrees, it is 1 1/16" up throw and 1 5/16" down. Now go get a device to measure it in degrees, they're far more accurate.

Elevator Throw - Bobcat
Dean
I fly a standard Bobcat with a Ram 500. I just went down stairs and measured the elevator throw. I have 1 1/4", 1", 3/4", up and down. This was set up by John Redman. I fly it on the middle rate. But then I'm a conservative flyer.

Thanks Gents
Just wanted to be in the ballpark. After covering and hinging, it turns out I had to shave a little to get more deflection. I now have a little over 1 inch deflection in each direction - quite a bit more than I am accustomed to with jets....that's why the question.

Guys..
Remember Tony comes from a competition precision aerobatics background. One thing you can be sure of.. his setups are going to give you a very smooth flying airplane. Basically you can't go wrong by following his setup guide.
Oh.. and IMO there's only one throw measuring device worth a damn.. and that's the laser pointer done by Jerry Budd (www.buddengineering.com)
