Hi Ray,

Thanks for the follow up. I have so much to learn about all the interconnectedness of these beasts!

Just back from the LHS. Heli (semi) guru there says I should maybe try replacing the 3 in 1 as he thinks maybe it sounds like a gyro problem. I have a spare so I could try that. I also have an external gyro (Align not eFlight) that I might try. Those externals bypass the internals don't they? So there are a couple things to toy with.

LHS also selling off new CP Pros for $139.00 Wouldn't that be a good price just for the parts? Also might be nice to fly a 'fresh' machine now that I (sort of) know what I'm doing.

Thoughts on that?

Thanks!

Scott

Binding in the main driveshaft can rob power from the overall system...you're requiring more power to fight the additional friction.
Please don't get me wrong....I am, by no means, an expert in model helicopter flight and I am only trying to "open doors" for further consideration. I'm a mechanical engineer and I build model things of interest.....I started my technical life as a jig and tool maker for a company specialising in steam turbines in 1959 and have been ensnared in that net ever since.
If you have a friend who has an identical machine, try swapping out the Tx and Rx for a tryout to see if the speed control is bad.......you could even have a gyro problem...there are a few links in that rudder control system. Is the clearance between the motor pinion and the drive gear too tight....that will sap power and load up the speed control system.
I remember one flight and the tail was a bit wild so I landed and found thatpiece of plastic tube which holds the tail rotor and gear together was a little displaced and the rotor was breaking free from its drive gear...!!!!!
Choppers...I have a question re the HBK2.
I finished a flight yestereve of just over ten minutes in around 90 deg. still air and bright sun. When I went to remove the battery it seemed a bit hot.....it's the 1500 and I think it's a 10C 'cos when I charge it, my triton shows 1.5 amp. The Pro's were fairly warm and the 400 batteries don't seem too bad but this raised my eyebrows.
Have you found a need to cut air circulation slots in the canopy to better supply cooling air to the battery area. It's got an area each side of the lower nose which could be opened up and I'm wondering whether air slots could be cut in the "windshield".
I'd be interested to hear your thoughts.....or am I being an alarmist....?
Lovely evening but 92 deg here in Kville......"but 92 deg".....???

Must begone....
Ray

OK gentlemen......
After her first flight I tore her down to check the freedom of movement in the swashplate system and now is much smoother and better. Her controllability is better and I'm getting good flight times.
My HBK2 has the brushless system (as pruchased from Jags) and she has been doing a good deal of hovering......not proper flyin'.
From that I kinda surmised there is a lack of air flowing over the battery.
I only assume that the battery (EK1-0183) is a 10C because when I set up my Triton charger for a 3 cell LiPo rated 1500mAh, it starts charging at 1.5 amps.
This morning I flew a pack sans canopy and the bettery temp felt just a little warm and not hot as it has been with the canopy.
Just to make a comparison I ran the 400 through a pack sans canopy and it's temp was lower too.
So I'm wondering whether I have an air circulation problem. The HBK canopy has two grilles adjacent to the motor and the poor battery is located right up front in "dead" air.
The top opening exposed to rotor downwash is a bit small so I think I'm going to cut the lower front of the canopy on each side to aid ventilation. I've laid it out on the canopy and I can get an opening about 1 1/2" long and about 1/8" wide on each side so I'm going to try that this eve.
We've now got a temp near 100 outside so I'm imprisoned in the house....us european types can't take the combination of heat and humidity.
"Mad dogs and Englishmen........"
Later gentlemen,
Ray
PS,
Just read about the Pros for a low price and "should I invest for spare parts" (paraphrased)
My reaction after owning two Pros is to suggest an HBK2. Don't get me wrong, the Pro is a good little machine but you're stuck with "non-changeable" electronics and replacements tend to be over-overpriced because there's only one supplier.
I believe you'll get a more friendly and adaptable and modifiable machine in the HBK2..

Ray,

For those who don't know what a sans canopy is, it's flying naked(not you, the heli) or without canopy!

Sounds like you're on to something there. One thing you're fighting is the ambient temperature, 100 degrees outside, so that's where your battery starts out at... I flew my HBK2 last night in the basement, it was about 70 degrees. After a 10 minute session the battery was only 93.8 degrees. Since yours starts out at 100 degrees, with it working the motor it will get 20 to 30 degrees hotter than the ambient. Modifing the canopy for better airflow, would be a great idea in your area. I have a Trex 450 canopy on my HBK2 and it's much bigger and probably helps air flow to boot. See if the B400 canopy fits the HBK2, it should be pretty close.

On batteries, the EK1-183 is 1500 mAh and 10C, the 0184 is 1800 mAh and 15C, the 0185 is 1550 mAh and 20C and finally the 0186 is 1800 mAh 20C.

Also, double check to make sure that your belt tension isn't to tight, if your not doing any 3D yet, a little loose is okay. I usually run mine loose. But not to where it's slipping. And it still gives me unbelieveable yaw control. with snap 90's and piros.

Thanks Chopper......
Flew both the HBK and the 400 with canopies this evening with the ambient temperature in the mid 90's.
I had cut the two slots in the forward lower section of the canopy of the HBK and they proved effective in that the "out of the machine" condition of the battery was nowhere near what it was before....or, at least, it seemed that way. Battery not swollen, motor was cool and the speed control was barely warm.
The 400 battery temperature seemed much the same.
Must see if I can grab the company's IR pyrometer for a couple of days.
Dude friend had the WIG on the lake this afternoon....pitch problems. She got into that pitch ogee curve again....climb and swoop over and over. I suggested he back off on the throttle even more which he reluctantly did and she softened up. She was peaking at about 24" altitude and way above that ground effect "layer" but once she was at about 6 to 9" she was much better....gotta get some photos before he piles her up.
Sun is going down and telescope needs to go out.

I hope you guys down in Indy are doing well. We had some monster storms come through yesterday and must have been crazy straight line winds for about 30 seconds, took out a lot of trees in the neighborhood and lost power for a while. It got black out and the rain was blowing so hard side ways you couldn't see across the street

My wife thinks I'm a nut for staying upstairs and watching it all go down

I flew 2 packs through my Blade tonight with the Fut 6XAS and had 4-5 glitches

I also found that I don't have enough roll with this set-up and darn near hit myself, ( I had to take evasive actions). Really hot here as well, my motors and batteries were extremely hot, more that usual. Does Jag hobbies take anything other than PayPal? It's confusing on their sight and I don't use PP.

I hope everyone has a great weekend!

God Bless Y'all,

Jay

Ray, I'm a huge nut for all things extraterrestrial! Do you know of a good telescope to buy? I'd love to see detail on the moon and maybe be able to look at Saturn and Jupiter. Any suggestions?

Jay,

It was VERY BAD weather for about 4 straight hours. Lots of trees down, roofs blow away, roads closed. The good side, no one was injured. You can always fix your house. I'm like you, maybe worse, I opened my garage door and watch it for about 30 minutes, I love stuff like this, I'm a nut case too. Never did lose power, couldn't believe that.

What's up with the glitches? Yikes, evasive actions, that's not good.
I have scars to prove the helis are dangerous, I must not have been fast enough.

Jag Hobbies, I agree, it's a little confusing on payments. I use Pay Pal, so it's a snap for me, just click away. I usually get my orders in 3 business days. Jim at Jag Hobbies, takes major credit cards or even a check. Checks have to clear the bank before shipment.
Either give him a call or e-mail him and let him know what you need. A GREAT guy to work with. On e-mails, he's back to you that day or the next at latest.

E-mail: jgase@jaghobbies.com

Phone number: 419-448-8442

Telescopes: Years ago, me and the kids would look at the moon with my telescope, it's awesome. You see the craters and everything.
With the telescope, you have to keep moving it to track the moon. Cuz it's moving!!!

Here's one site, just google "telescopes" theres hundreds to choose from.

Thanks Dave, I think I'll give him a call and see. With telescopes I'm sure there like anything else, you get what you pay for. My friend just bought a pair of expensive Binoculars and I was amazed at how clear and focused they were compare to a every day bino.

God Bless!

Jay

Jay,

Telescopes: Your exactly right, you get what you pay for. I know you are a NASA nut too. An love the outter space. It amazes me too.
Check to see if theres a local telescope place in your area. Don't get one at SEARS or K-MART!!!!

I sold mine years ago, and wish now I didn't.. I think it was about 1,000 power.

God Bless ya,
