Los Angeles Heli flyers.

[Lota Fun R]

May fly Tujunga on Sunday? If it's not being used we'll have a great day, if it is, we'll invade Apollo and use the heli pad to the right.

Any that want to come fly, the more the better.

Lets have some fun. :smokin:

Carson field is nice, guys. a few of the OC guys fly there...710 frwy at Carson st.

[Lota Fun R]

It was a disappointing weekend for sure.

Dave and I were able to go flying at Robins field, everything else was shut down, Whittier and Apollo.

I'm going to join the Santa Fe Dam club and fly there for the most part.

Had a great time flying the Raptor and one of the 450s, the other needs the tail replaced.

Awesome weather, light winds and perfect temps, plus the shelter was nice too


Here's some pics from Robins today..

It was just Dave and I for most of the day, Bert was there as well as few others,....light wind most of the day, was perfectly calm for one flight.

Better camera is on the way and next time the pics will be from Santa Fe Dam, invites to come fly will be forthcoming to those interested..

What/where is Robins field?

[Lota Fun R]

Robins is too far away for me normally. It's off the 210 towards the 5.

Flying Whittier tomorrow/wed. 10am, should be awesome.

Hi guys,

Glad to know lots of hover lovers in several L.A. county areas. Might visit the Robin's Field soon which nearest to me but just couldn't find time right now. By the way, a friend of mine Dennis (the friendly guy at Robin's Hobby in Glendale) said that active AMA membership is required for those pilots who are interested to fly (but don't know yet) at Robin's Field..See you there soon..

[BiggerDanno]

Ordered most of the stuff today for the 700. That was a wallet shocker!:shock:

Still have to get fan, governor, Carbsmart, servos for tail, throttle, and carbsmart, and....the heli. Everything else is on order.:)

[Airboss]

Congradultions Danno, you will love the 90.

I went flyng with Mitch today at Whittier Narrows.

It was a "Lota Fun" (sorry, I had to do that).

The photographs on the forums do not do justice to the paint job on his Raptor canopy. His Raptor .90, has a great deal of power (more than mine-I told him that, if you can still see the helicopter through the smoke, it is not rich enough...)


The "Correct" parts were very well made (flybar cage and blade grips).

He was also doing an interesting vertical "S" manuever-a half inside loop to inverted then a half outside loop to upright-pretty impressive.



I put four flights on the Knight 3D and three on the Raptor 3D, so I have had enough for the day.

At this point, the Knight 3D seems to be about the best thing I have ever flown (in over 30 years-man am I old).

thats funny guys. Mitch is still thinking about how much those engines cost so he's keeping it well oiled.lol
I have heard simillar tales about the knight 3D, but I think they are a bit biased, do you notice any differances in flight from the rex 600n compared to the knight? and what about the weight? how does it compare to rexc and JR 3D.?? just curious and I respect your opinion richard cause we both been doing this a long time.

[Ah Clem]

Airboss,

The mixture on Mitch's machine was controlled by a Carbsmart, so his mixture was very good. I was referring to my machine trailing clouds of smoke (I always run rich intentionally-I don't need the massive amounts of power that the 3D guys need).

I have flown three different TREX 600N's. All three flew beautifully. Of the three, Jason Chow's was, by far, the quickest.

I do not know the weight differences between the 600N and the Knight 3D. The Knight, to me, feels more nimble. Rate or roll and flip seems much faster. The tail, although belt driven, is very solid. The 600N is slower and smoother in response. Power to weight is very good on both.

I seem to be able to get a better axial roll out of the Knight 3D than the 600N, but I would need to fly a 600N more for purposes of comparison.

Truthfully, I do not think you could go wrong with either.

In 50 or 60 flights, I have had to replace on broken motor mount bolt, and the ball links on both ends of the tail rotor pushrod on the Knight. The windshield is also showing signs of stress cracking where the screws hold it to the plastic canopy. There than that, it is still slop free and tight.

The JR3D (I assume you mean the Vibe .50) I have never flown, nor seen in person, so I have no basis for comparison.

[Airboss]

I will hold out for the Vibe 3D and see how its flying before I make a choice. I had a good look at that new JR 50 and only one thing looked off. and that was the cyclic bellcranks dont have a center support between frame halves its just a 3mm screw through the fuse. I was pushing and pulling on it to simulate stress and it was moving around. a week link that may cause the frame to crack. (never to this to your freinds heli) hehe...my CF synergy with the pumped OSszh is awsome and a blast to fly so its going to be hard to top.

[Lota Fun R]

Great day flying. Glad you could make it out Rich. :thumbup:

The carb smart works. I get a couple minutes "maybe" more flight time but more importantly it makes great power....... for a SX C spec.

I let Eric Stolz take it for a flight today, he liked it. :smokin:

The Raptor is working really well, I've got no complaints.

Rich's Raptor was working perfect, there's a difference between mine and his and I can't put my finger on it, his head speed is actually higher than what I normally run but it doesn't seem like it.

Hmmm???.......

None the less, great day. :cheers

[Airboss]

could be the mains....

[Lota Fun R]

He's got almost the same set up but I might have more pitch?

[Ah Clem]

"Rich's Raptor was working perfect, there's a difference between mine and his and I can't put my finger on it, his head speed is actually higher than what I normally run but it doesn't seem like it."

Mitch,

Yours sounds faster, but the RPM is slightly slower on the head (only about 70 RPM I think, per your tach).

Part of it is, I think, the pipe. You are running a Muscle Pipe and I have the Hatori (I gave up trying to get the Muscle Pipe after a couple of months).

Also, mine has a bit of the four cycle burble to it (again, running intentionally rich), yours, with the Carb Smart, sounded like a solid two cycle (still plenty of smoke though).

Both machines seem to be very solid.


It was a good day.

[Airboss]

Muscle pipe all the way, it gives my OS the punch it needs. I run both OS 90 engines one pumped and the other not,szh/szh pump, same pipe. these engines kick butt on my N9s .Long uses the YSsr and had to alter the gearing to get it to work with the hatori pipe.he runs 8.0 and stock is 8.27. so having a muscle pipe helps get that extra top end power. BTW all that BS over on the OC thred is just for fun so you all are welcome to join us. finless has been messing with us a bit and its Fn funny.

[Lota Fun R]

Didn't realize the pipe made so much difference.

Hope to fly Whittier this Sunday, maybe Saturday too. :smokin:

You should know better, the pipe is what makes the engine breath, all that scavenging makes the glo engine happy.

[Lota Fun R]

Ya, but these pipes for these diesel two strokes are something else.

Anyone got an old pipe I can cut in half, I'd like to cut a few different ones apart.

Tuned pipes are a black art, I'd like to make some different pipes.

[Airboss]

AREA 51 thats what the others do now and in the past.. those pipes all have their own special baffle and chambering to get those high freq pulses under control. I have a raptor 90 pipe that makes horrible power on my 0s91...switched to muscle pipe and H/P feels double..lets cut it open and see whats up with the TT pipe but your not cutting my MP. need a small bore camera to look inside.

[Lota Fun R]

I'm looking for one that is not usable anymore. I know an expert on this, I'll give him a call. Plus, he's got the machines to make anything I might want.:smokin:

I know one thing I don't like about the MP, the header has a lousy fit up, I would think that it matters, but maybe it doesn't? Could be just basic back pressure is all that's needed, the MP does have a big chamber compared to others.

[Airboss]

we know its not hard to make the pipe and weld it together, thats your dept. but to make the same thing each time might be harder. tuned expansion chambers work best for top rpms.look at racing planks and boats for rc.
