Thank you !!!!!!!!!

I really appreciate the help. I will lower the normal curve on the yellow one.

Can you buy that landing gear any where ? I couldn't find it.

Or maybe there is a better style ?

I just glued the ones I have for now.

I found new TDR canopies from overseas. I have to put them together.

I crashed the white one and repaired it. The tail wires are run inside the boom so fo a quick repair I just shortened it by 1/4". Should I just fly it like that for now or change the boom out ?

The tail boom length should be right around 130mm when using a brushless tail motor or 150mm center of main motor to center of tail motor. I always preferred running the tail motor wires inside a hollow 3mm CF tail boom.

Instead of reading real-time throttle value for targeted headspeed, arm mode sets targeted headspeed by reading the max throttle seen during arming sequence. Once armed, the ESC will run in throttle mode until about 20% throttle (may change in future BLHeli versions) and switch to governor mode for the targeted headspeed. Any real-time throttle change above 20% will be ignored by the ESC. To properly set up arm mode, Set up normal curve to 0-20-20-20-X where X is your desired throttle value corresponding to your target headpseed. Throttle curve for idle-up can be anything as long as all values higher than 20%. Will talk about that later. To arm ESC in arm mode, move throttle stick to full up instead of part-throttle for about 1 second and then back to zero. This will make the ESC reads throttle value X. To start motor, flip to idle-up mode and then move throttle stick to just below zero-pitch and wait for spool up. Do not use throttle hold or idle-up switch to arm ESC in arm mode. The problem is that when 3-in-1 board sees a sudden jump of throttle value from zero to more than 50%, it'll trigger its soft-start procedure. That means until you wait for soft-start to finish (about 5s for V1 and 10s for v2), the ESC will not see the targeted throttle X value to correctly set governor headspeed.

Really good read. Now I understand the ESC better. Thank you !!

The link you gave me is for the stock landing gear.

I will have to buy it and try it with the hyperion 550 mAh batteries. I was hoping to find some stronger landing gear. Can't seem to find the type I have now.

I will measure mine. The only thing is when you run the wires inside you have to solder the plug on each time.

Update. My tail is 155 mm to the main shaft now. (165mm to the Center of main motor) So it should be OK. Would really like to get some coloured Lynx main blades after I cracked the other one I had.

Hit up Rich at Airtimerc. I think he has a style of mCPX skids that will accommodate Hyperion 550's. His skids are pretty much indestructible and good stuff.

Thank you !! Again.

I sent him a message for two sets.

A big +1 for AirTime. He made me custom skids for some different batteries I wanted to try. In general, his last several months of abuse where the stock skids tend to break with just a tiny bit of abuse. The airtime skids are worth every penny, and Rich is a great guy too.
