Originally I thought maybe it was the 4* positive incidence or 4* prop up in the motor mount but found later that my cg was a 1/4" aft. I was able to fix that issue with 10 g of chucky cheese tokens. it is slightly forward cg now. hopefully that helps...

Any ideas?
as long as you stay away from chucky cheese video games,should be okay

Are you kidding my son would pitch a fit if he knew how I use the left over tokens.
Getting the cg slightly forward helped for calm throttle changes. However from a glide speed to light speed it really dives.

I wonder if I have been thinking thrust and incidence pertaining to pushers backwards, being it is a pusher not tractor. with my 3d planes, a tail heavy plane balloons when throttling down, and slightly dives when throttling up. Similar to what my stryker was is doing. Thrust angles are to prevent p factor, and slip stream in a tractor plane not a pusher. Being they are Yaw factors mostly. however p factor and motor torque could affect a pusher plane.
Again since this is new to me I hope some one will help me understand pusher thrust angles, and why and when to use up/down. Does using a pusher prop change factors?

Hi Guys,
I was wondering if any of you know a good lazer cutting company that will cut a set of stock looking vertical finns for a stryker? I work 2 jobs have a bit of time to play but not many tools to cut ply.

Thanks in advance.
Joe

Get coroplast from the sign section at your local lowes or Home Depot, do a search of this thread for fin template (or use the thread tools above to look at attachments in this thread), print a template and cut yourself some fins with a utility knife. Glue fins securely. Profit.

I have posts in this thread asking similar questions, most people use foam board or coroplast for replacement vertical fins

(1st person shooter games - especially the games that over-emphasize the movement of the shooter as they walk - also give me trouble too so this is mostly my own issue with too much motion in videos).

Nice flight though.
Thanks!

Thanks Gryphon,
the up thrust helped tremendously, Barely any diving is perceivable during quick throttle up.

My Stryker is stupid fast, But getting boring quick. Time to try some rudders and a bigger batteries.
