Hi.

With all due respect, I noticed on your vid #71 on youtube, you taxied the model around a bit, then captured it between your legs and throttled up.

I know it's a quality fan, but me personally, I would stand clear (and anyone else) of any high speed moving parts. Especially in the rotors arc.

Again, great work and very helpful.

Steve

Noted, and a great point. People, don't do what I did! RC should not be a form of birth control!

So I went to the flying field today to test out the brakes that are now working properly, along with my corrected tracking. Charged all the batteries, headed out to the field, pulled out the plane and realized… Those fancy batteries I charged were still at home
"No problem, I'll fly my helicopter" I said to myself. So I got it out, took off, and about 20 seconds later it blew itself up in the sky and came crashing down.
Looks like a bolt didn't have enough loctite and came out of the rotor head. Ha! I love helicopters! But it was fun and should be easy to repair.
Not all was a bust. I got to meet some new members today, one of which will be going to college with our son in the same field. He had cool goodies, one of which was a self designed quad copter. So still had fun and was a relaxing day.
Have a safe 4th everyone!

I'm sorry, I don't have any idea of my thrust yet. Right now it's set at "hurts my ankles if I'm standing over it"

+1 on that.

I tested the HET 9305 and 700-68 motor (3000W combo) when all of a sudden the rotor just took of and flew forward like nobody's business. I now try those from a safe distance...

Ok, well when I was filming I had the same thought but I hate it when the cameraman talks because it's so loud so I kept my mouth shut. He couldn't have heard me anyway.

Besides, he had me do the same thing with my shins on the LE until I screamed owwwie! And I figured if he was going to put my valuables in jeopardy then it would be his just rewards if the fan came apart.

Actually I felt pretty safe since the fan had been run up a bunch and the hatch was over it but I guess you never know.

Ok, it was a dumb EDF noob mistake, I still have all my body parts and I am the temporary poster child of what not to do. I appreciate everyone's input and will not make the same mistake again. Going forward please send me an IM on this subject and I'll try to keep the thread focused on the build.

The plane is still in the car from my last unsuccessful trip to the flying field. I've decided it will stay there until the shop is cleaned up. I need two more 6" servo extensions from the power switches to the batteries and we should be all wired up!

I want to test the brakes before I hook up the ailerons because that will involve removing the duct. I'll head to the flying field on Saturday and get the ailerons hooked up Sunday. That's the plan.

I tried again the flying field today and the brakes work fine. I think I like the solid braking better than the "anti-lock."

Dave at the flying field helped me get my radio programmed so that the brakes are activated when I put in about 40%-50% down elevator. I just couldn't get it to activate. It turned out all that was to crank up the sub trim some.

While testing the brakes we noticed it started listing to one side. I thought that was strange. When we brought it back to the bench we noticed one of the bolts that attaches the gear to the bulkhead was gone! Doh! I checked the other bolt and it was loose as well. I was planning on going through and applying loctite to everything later, but maybe sooner than later is better
We found the bolt on the runway and put it back in.

One last "that sorta sucks" moment was when I wanted to test the non anti-lock braking. The balsa block I have holding the pushrod tube in place for the nose steering busted loose from the fuselage. I'll make another with some ply and hysol in place.

It's hot and miserable so I'm not sure how much progress I'll make this weekend.

I'd recommend putting your brakes on a separate slider switch and not mixing them with your elevator. I just went through the process of getting my turbine waiver and I did the same thing by programming a mix but my CD told me it was a bad idea having my brakes on a mix. He said pushing down elevator at a high speed will lighten the rear of the plane and create some instability during roll-out. With that recommendation I programmed my brakes to the right slider on my transmitter and it works great.

I had it on the slider already and moved to elevator today. I can adjust how much elevator is needed to activate the brakes, so I can dial it down. I'll play around with it and see. Easy enough to switch back. Thanks for the feedback.

P.S. for those that are wondering, the air sequencer has a safety built in that does not allow the brakes to be used when the gear is up. That way you don't waste the air.
