Status: offline 		Hey Nick,

And I thought I was a night owl! 2 or 3 AM is my limit on the weekends, otherwise there is heck to pay on Monday morning! I haven't stayed up that late in a long time.

I had a really positive experience with HeliProz, they had very quick shipping, excellent communication, and everything went smooth as silk. I think that they are located in Montana, even though, it did not take too long for shipping here to the East Coast. They seem very cool, when I ordered, they were going on some sort of heli-fly thing over the weekend, and left a note about shipping on the holiday weekend. Seems they are very heli oriented for sure! Knowing what I know now, I could have ordered the screwdrivers individually online, but it's still a good thing to have. There are other uses for JIS screwdrivers other than RC helis....like laptop computers, and other small electronics.

The servos didn't make it today, but I stole the ones out of the new CPP....I knew it would come in handy! I put them in, but I'm still not 100% certain that took care of the problem or not. I tried to test fly it, but we had some big storms come through, to end the very hot and humid day, so I really couldn't tell for sure.

I was doing the nose-in with the B400, but I have no problems doing it with the CPP indoors, in the shop, with no wind. I got that thing really, really stable before it all went to crap! There is something kinda scary about looking at a helicopter dead on like that...it's like it's staring at you...daring you to make a mistake!! LOL

I got very little flying in today, before the storms came. I did fly a full pack in the original B400, no issues whatsoever with the 93 degree ambient temps. I did not have my Raytek with me, but the ESC and motor were very hot to the touch, kinda like they used to get when I had the heavy training gear on....the ESC was probably pushing 150, if I had to guess. The motor, not so much, probably 110 I would guess. That was after a full 10 minute flight...

I finally got a chance to fly my other B400...and it flew great. I noticed two things...it was quieter, and smoother. I think my blades are out of balance. I had a little tip over a while back and the covering is tattered somewhat...and also, the stock Eflite servos made it feel "mushy" ...not responsive like the JR's. I even bumped the expo down from 15% to 10% to try to get a better feel, but it still didn't feel as "connected" as the JR's do. Good servos do make a difference!

I had an OK day, was very challenging, flying right before the storm hit...prettty breezy...I'm getting alot better at dealing with the wind. Not to be confused with LIKING flying in the wind...I just have learned to compensate for it better than I used to. I had a couple of good right circles, my sticking point at the moment, and had a couple of decent nose in's as well.

I'm a little disturbed at the way the CPP was acting...I'm not so sure the servos did the trick. I also think that maybe the lighter Eflite blades might be messing me up, I have it all setup for the heavy blades...it was all over the place, even more so than it should have been with the wind. I also have to reglue the tail gearbox to the boom, it always breaks loose on a hard landing. I will try again tomorrow, and if nothing else, test it in the shop on Monday. If I have to, I'll swap the gyro and AR6100 into the new one, and start over!!

As much a pain that little heli can be, I still enjoy flying it, when it behaves...it's like a love/hate relationship of sorts...LOL Every time I'm ready to give up on it...I look at it sitting there, and just have to get it back in the air!

Sorry for the predicted rain for you...I have no idea what tomorrow will bring here, except that it will be HOT. I am going to do my best to get some stick time in regardless!

Take care,

Glenn

Good to hear Heliproz is a good company.

I got the carbon rod for the canopy, but the LHS still doesn't have the bearings I need for the CPP. Good to hear you were able to use the servos out of your second CPP.

Now I don't have to worry about flying in the heat. It got up to 96 degrees today.

Yeah there is a big difference flying with the DS285's compared to the stock servos in my CPP. It seems like my Belt CP blades are balanced pretty good from factory, but I never checked it out my self. And I am curious how balanced the T-Rex blades are.

I wonder if your heavy blades were having more of a gyroscopic effect and affecting the way the CPP handled. You have more determination if you were going to swap the gyro and receiver to the new CPP. I would be too lazy to do all that work.

When I am having a frustrating time with the CPP I just take a break for a couple of days then fly it again. It is usually better for me if I take a break from flying it.

I also like to fly no matter what the temp is. In the winter I would go out and fly in 32 degree or colder weather. And my electronics would come back at room temp after a flight, so I could go flying right away after that flight.

Nick

Funny you should mention that carbon rod for the CPP, I also seem to be missing mine as well. I just borrowed it from the new CPP...

I was thinking the same thing, the heavier blades do make for more gyroscopic effect, maybe that has something to do with it. I will probably put them back on to see what happens.

Yes, that would be a big plus in the winter, no cool down period. If I only had one heli to fly, it would be a bummer, having to wait for it to cool after each flight.

I got to thinking today, and got my digital camera out. It will do video, but it would probably be pretty lame. I got a memory card for it, but I don't think it will work too well for doing heli vids...it has no zoom or anything...the heli would probably look like it was a mile away... I got the camera out so I can take a picture of my fleet for my RCU profile. I finally got around to listing my helis on my profile last night...

Well, tomorrow is another day...hopefully I can get more flying in if the weather will cooperate.

Have fun finishing the T-Rex...how is it coming along?

It sounds like the new CPP was worth the money.

It might seem like you were doing 3D with the camera if you can't see the helicopter clearly. I will have to check out the pictures of your helicopters on your profile. I have fun adding stuff on mine. I sometimes check out a few profiles that are listed on the main page of RCU and it seems like their fleet goes on for ever.

I finished programming the ESC and made sure the servos moved in the right direction on the T-Rex. The swashplate isn't level right now. So I have to set up the head assembly and I am done. I am waiting for a response from Spektrum to see if it is safe to fly with my receiver. And I also have to figure out were to mount the ESC and receiver and were to route the wires.

Nick

Yeah, it sure is nice to be able to grab a part off of the new CPP when I'm in a pinch. I'm determined to get it flying well again...I really enjoyed flying it outside just before it started it's strange behaviour...

I haven't taken any pics of my "fleet" yet, I just filled out the "my models" info on my helis...they give you little pictures of the models you list... hopefully, I can line them all up in a row, and take some pics and post them tomorrow...

Sounds like the T-Rex is getting close, for sure.

It's good that you are taking your time, and doing it the right way...I'm sure it will pay off for you.

What kinda goodies were you looking at at HeliProz?

They do have a nice selection, for sure.

Good luck on the final steps on the T-rex, have fun with it!

Glenn

I just noticed something kinda funny...no one responded yet to my post about the fuel tubing that comes with the CPP orings....LOL I don't feel so stupid now, I guess no one else knows, either!!

Just thought that was kinda funny!

I was thinking about getting another helicopter from Heliproz in the future. Right now the T-Rex got rid of all my money for helicopters.

It is raining pretty good, so I won't be able to fly any of my other helicopters except the CX. So I will probably get back to work on the T-Rex.

You could use fuel tubing to hold the tail blade on or for the skids. I know I always loose the tubing on my CPP. But I don't know why they would put them with the dampners.

Have a good day.

Nick

Wow, looking to expand your fleet again? You're gonna catch up to me soon! I like Heliproz, they seem like a good outfit.

That sucks that it's raining there, I have no idea what the weather is supposed to do here later, but I have my usual Sunday chores before I can fly.

Oh yeah, I can find a use for the tubing, no doubt....I am thinking that Eflite must consider that bag a rubber parts bag or something, because I don't think they sell the tubing seperately.

We'll probably never know...LOL

I'm gonna get the CPP out in a little while, and see if I can make any improvement on it's sorry performance from yesterday.

Have fun with the T-Rex...

I gotta try to take some pic of my fleet today, if I remember...

I would like to have a couple more helicopters, but it will be a few years before I get one. I am just doing research on what is out there and what I would like.

I just finished setting up the head assembly. And it turned out most of the pushrods lengths were wrong in the manual. I just have to double check the blade tracking since I locked the pitch gauge, then the next time I will unlock it and see how close it is. I am so used to setting the pitch with the flybar on top, so it was different doing it with the flybar under the blades. Then I have to set up the gyro and tail servo. I am getting really excited for the maiden flight!

Try to have fun with the CPP. Maybe it will fly like it used to just by sitting around.

Nick

Status: offline 		Hey Nick,

Well, I FINALLY fixed the CPP...and you probably have seen this, but it's new to me...

I finally just ignored the aileron, and what it was doing, and just started watching the servos as I moved the throttle/pitch lever. While I was watching it, the left rear servo, the only one I DIDN'T replace was acting funny. But not in a way that one would think. Let me explain.

When I would very slowly increase the throttle/pitch, the left rear servo would move, but the others would not. This was with a very small stick input, maybe 1/8 of an inch of travel of the left stick...All this time, I was thinking that it was the other two servos, since they were not responding with the left rear one. So, I substituted the last servo from my new CPP (that thing has come in VERY handy, indeed!), so now I have all new servos.

Problem fixed. I didn't know a servo could fail in that manner, what it was doing was responding too quickly compared to the other two. Now, I have a very smooth transition all the way through the swash travel. FINALLY. A note; it was acting funny at the extreme ends of the travel of the left stick, but otherwise OK. This was also affecting the aileron, thus causing the altitude changes I was having when moving the aileron left and right. WHEW!!

I must say, it is quite rewarding to track down and fix something like that...it's just kinda frustrating in the process!

Persistence pays off.

Now, I just have to set the pitch, and blade tracking again.

I also am stuck as to which blades I want to try.

I think I will go back with the heavy blades, and try to not hava any hard landings.

I have two more new servos coming anyways.

Now I don't know the status of the other two servos that I put gears in, thinking they had too much play in the geartrain! ARRGGHHH !!!

Well, that's something I can work on later...sort of a project.

When I get the AR6200 back, I may put it in the spare CPP, and try to make it fly somewhat stable. It is almost ridiculous to try to fly it the way it is with that radio.

I can make it just like the original, minus the G110 gyro...

We'll see.

I can imagine your excitement with the T-Rex!!

Hope you can fly it soon!

I hope I can get some calm winds later here, it's kinda gusty now...we'll see.

I would love to have a nice flying session to wrap up the weekend.

Take care,

Glenn

Good to hear you got the CPP fixed and flying.

I was reading the thread about which new Blade to get and I think you said you did a figure 8. Nice job. Was that with the B400?

I finished the T-Rex around 4. I just need to glue the boom supports to their aluminum mounts and glue the tail pushrod guides to the boom. That isn't the common practice, but it worked great on the Belt CP so I thought I would do it again. Then I need to clean the wires up since they are all over the place right now. The manual was talking about filing the edges of the frame to prevent cutting the insulation on the servo wires. It look like a little was scraped off already. I fired it up with the blades and it sounds a lot better than my Belt CP. Then it took about a minute for the blades to stop after cutting the throttle off.

I feel pretty stupid about my AR6200. I thought it had a problem because it was flashing, but it was just doing what it was supposed to do after a brownout or unplugging the battery.

I hope I set the direction on my GY240 correctly. I couldn't see my pitch slider move when I yanked the tail, so I will see what happens in a hover.

Hope you have some better weather.

If the weather is good tomorrow I will test fly the T-Rex.

Nick

Status: offline 		Hey Nick,

I flew the B400 and the CPP earlier tonight. I had a great flying session! The CPP flew pretty well, very stable, but the tail was all over the place, I think it's time for a fresh tail motor. If it had a new tail motor and no wind, I think it would fly like a dream again.

Yeah, I was so pumped, I did a few figure 8's...it really didn't start out that way, but I was going from left to right, and back, so I changed the direction I was turning, by making a wide left turn, and was making pretty large, high figure 8's !! It was a very cool feeling! (this was with the B400. not the CPP)

The pictures of the T-Rex look awesome, looks like you are almost ready! Yeah, I read about the sharp edges on CF frames somewhere. Also, they can cause some radio interference in some cases, like aluminum frames can also, so I've read.

Hope yours doesn't have those issues.

That's good news on the AR6200, just a normal thing?

Hopefully, your gyro is good also.

It is weird, I can make left, sweeping turns when the heli is to my right, but not when it is to my left...not too comfortable with that just yet. I made a bunch more right circles and turns as well today. It's getting easier.

Hey, when you get a chance, check my profile, I posted some pics of my fleet on there, see what you think!

Gotta go, have work in the AM!

Take care, have fun with the T-Rex!

Glenn
