What prop you going to run on 10S?
I'm sure you can come in arounf 18-20lbs if you keep it stock. Should balance no problem with the batteries alone.

Lou,
I hadn't planned on doing any more tests on the prop. Should I be? At the moment I'm still with the APC-e 22x12.

Good Luck!
I Hope the weather clears up for you. I'm guessing there is still snow on the runway. TW

Just got back to town and looks like majority of the snow is gone, although we have had a lot of rain. I would expect we are still a month away from being able to get into and fly at our field...and two months or so from flying anything nice there. The club hires heavy equipment to roll the field in the spring. You'd be crazy to fly anything of any importance or weight before that.

Also, thanks for the vote of confidence on the motor choice. I'm aiming to go with 10S, should still have plenty of power.

Got the stitching other wing panel finished today (only the top of the wing so far). You can see the pitot tube in place. It slides into a brass tube in the wing which has a pin soldered in the rear of it. That pin engages a slot on the end of the pitot tube so it stays vertical.
I am working on an H-9 Corsair 60, 1/8th scale. I am trying to get the meaurements to fabricate a pitot tube. I have not been able to find anything definitive. I would appreciate any help you could provide.

Thanks, Wayne

Wayne,
I just took a best guess from a 3-view dwg I have. I worked out the size of the pitot vs the wing chord at that location, then used my wing cord at the pitot location and the same ratio to come up with mine.

Sure I'll measure Monday if I can remember where I put the tube.

Wayne,
My pitot tube is 5.5" long and sticks out 3.25" from the LE of the wing. It's located 2.5" in from the tip on the left wing panel. The wing chord at that location is 9". The wingspan is 74" overall.
I hope that helps serve as a guide for your to scale off of.
Sean

This will be a great help Sean. Can I bug you for the diameter also?

Sure, I used a pce of carbon rod for the main pitot and a pce of wire for the front tip. The main tube is 0.159 OD and the tip is 0.096 OD. The tip is 5/8" long.

Again, these are just my best guess for a pitot and what looked like it was correct.
