Anyone have a good complete starting setup for the JR 8103 or similar tx. Thanks for any help.

You do realize that you can't use the OEM 4in1 with a JR radio, right?
Futaba or Hitec tx, yes. JR or Airtronics tx, no.

I just upgraded my Blade with a GWS 6ch receiver so I could use my 8103. Works really good and with the Bell-Hiller upgrade it's very controllable. I don't have my Tx with me right now but so I'll post my settings later.

Bikenboatn:

I'm new to RC -- have a E-flite Blade CP for my first effort -- and have been considering a Futaba T9chp Super or possibly a JR 9303 for my first radio. Your comment about OEM 4in1 incompatability of the JR radio caught me by surprise.

I'm thoroughly confused about radios and I'm lost in the jargon of the hobby.

I want a good radio that minimizes hastle and provides quality control for my CP, and (looking at the probable future) I want that radio to provide quality control of more advanced helos, gliders & airplanes.

I will fully appreciate any advice you can muster.

you can use jr radio if you do the hack. I am using the jr6102 and love the options it gives me to fit my style. I am still learning but the jr radio helped. being able to control the throttle and pitch cures are a great. If you will do a search you will find information regarding how to do the jr hack. Radio's are just a personal preference. Read and ask around before you make your deciesion and you will be much more satisfied.

By "hack" do you mean tearing into the electronics of a JR radio or simply playing with the program in the radio?

I don't remember exactly what the difference is, but I think it has to do with the shift of the radio signal. The shift of the 4in1 is the same as shift on Hitec and Futaba tx's but is different for JR and Airtronics. That's why the only way to use JR or Airtronics tx is to remove (hack) the stock rx out of the 4in1 and replace it with either a JR or Airtronics rx. There's a lengthy post here that explains how to do this hack.

If you're just starting with the BCP, my recommendation is to just leave everything stock. Learn how to fly it as is. You've got enough to learn just flying the BCP without complicating things by changing tx's, etc. Once you can successfully drain the stock battery w/o crashing, upgrade to 3s lipo's. You can continue using flat bottom blades with 3s lipo's, just use the 8T motor and install both heat sinks. That combo will give you the longest flight times which is good for practicing. Learn how to fly in Idle-up mode. Then use the symmetrical blades and 9T motor so you can handle wind better. Once you can fly it well that way, you've probably learned enough about the hobby to really upgrade the BCP by adding the Bell-Hiller head, DD tail mod, and computer Tx.

Once you've gotten compentent flying the BCP set up like that, going to a larger heli, like TRex, will be fairly easy. That's the exact route I went. I'm flying an MX400 which I never would have been successful at if I hadn't started with the BCP. In fact, I still fly the BCP more than the MX, because the BCP is small enough to fly everyday in my driveway. The MX is just a little too big for that.

Be sure that any computer radio you get has heli-specific functions primarily CCPM, and multi-point pitch and throttle curves. Beyond that, it's mainly personal preference and how much you want to spend. If you get a radio that your buddies have, they can help you set it up. Otherwise, you'll be on your own to figure out all the settings, which can be a little intimidating the first time around.

The " hack" is separating the gyro and tail rotor mixing from the Eflite reciever,,,,,,,,,pretty easy and there are posts in the archives that cover it very well, seems the internal design has two layers of circuit noards, one for the radio and one for the gyro and mixer for the tail rotor, ESC etc,,,,,,

the Futaba and he JR radios use the same frequencies but the 'shift' of the signal is opposite.

BTW, Hitec makes recievers compatible with both JR and Futaba, both my Shogun and T Rex use Hitec receivers, and they are not interchangeable,,,,,,

Thanks for the fast feed-back and advice.

I read about the hack -- sounds fairly simple-- but many of the downloads were knocked out for me. Think it has something to do with my ISP (AOL) -- gotta dump AOL when I get the time.

I'm not in a big rush for a radio (yet). Think I'll follow bikenboatn's advice for a while -- I'm currently on about a $50.00 per minute flight expense due to the crash experiences (Doesn't include my time).

Thanks again. Kudo's to the people who developed this web site.

My Set up on a JR8103

Ch1- Thro - Norm
Ch2- AILE - Norm
Ch3- ELEV - REV
Ch4- RUDD - REV
Ch6- PIT - REV

I've set the Swash Mix at
AILE -60%
ELEV 60%
PIT 43%

Pitch Curve is 50% 50% 100%
Throttle Curve is 0% 50% 100%

Make sure the Swash Typ is set to 3 servos at 120degree

If you do any flying outdoors in wind, you might consider lowering the first pitch curve value a little to say, 30,50,100. That will give you a little negative pitch so you can descend when wind causes you to climb. Along the same lines, if you raise your second throttle curve value a little to say, 0,75,100, then you can maintain headspeed a little better during hover.

Personally, I think the best thing to do is to setup your Idle-up curves and fly in Idle-up, not Normal. I do all my take-offs, flying, and landing in Idle-up. Makes flying in wind much better, as you're able to "drive" the heli down with negative pitch, while still maintaining full headspeed and cyclic response. It also gives you practice for inverted flying, though I admit, I'm not at that point yet myself.

If you setup Idle-up, a typical pitch curve is 0,50,100. With the BCP and it's marginal-little brushed motors, a throttle curve of 100,100,100 actually works pretty good. That's what Ron Osinski of Horizon Hobby recommends and flies with his BCP. I use those values with my BCP and Optic6 combination and like it a lot.

With the Bell-Hiller mod, I find using about 30% expo smooths out my flying considerably. Otherwise, it's way too twitchy.

The 8103 has 5 point throttle and pitch curves. The 4-in-1 is a negative shift receiver like Futaba/Hitec for JR you have to hack or convert.

Thanks for info.

Thx for the information. I'm currently flying indoors since the weather has been so bad here. I'm still tuning my bird to my Tx. Haven't messed with the Expo yet but i might to tame it down a bit. For the most part it flies pretty good and I was surprised how easy to fly it. Now I need to work on getting out of tail in hovering.

icqa,


With the 5 point Throttle and Pitch curves on the JR 8103 radio do you have

Throttle Curve set to L 0% -- 1 INH -- 2 50% -- 3 INH -- H 100%

and

Pitch Curve set to L 50% -- 1 INH -- 2 50% -- 3 INH -- H 100%?

I would really like to know also. Can someone please reply to head's post?

I usually set up my normal curves something like this:

Normal Pitch: 35,40,50,75,100.
Normal Throttle: 0,75,85,95,100.

That will give a little negative pitch at low stick so you can come down easier. Also, the steep throttle curve gives you power at low stick so you can use that slightly negative pitch. Although like I mentioned earlier, I always fly in idle-up using curves something like this:

Idle-up Pitch: 0,25,50,75,100
Idle-up Throttle: 100,100,100,100,100 (for brushed motors).

These values assume you have your main blade pitch set at zero pitch when collective is mid-stick, mid-trim, in idle-up.

My curves are set up the same way as BikeNBoatN. The stock motor really doesnt have much power so you have to keep your "normal" throttle curve pretty high unless you fly in Idle Up with 100% throttle all of the time. I like how Idle up flies, but i am usually slow to flip the switch in a crash. I just usually run an even higher "normal" throttle curve, 0,50,90,100,100.... This way I can fly with idle up headspeeds to help with wind but still just pull the stick all the way down when i know a crash is coming and stop the rotor inertia.

What would be the curves for the brushless set-up with a 3to1? G90 gyro, Duel tail motors.

Thanks,

For the E-Flite brushless 370 4100kv/G90 I use 0,50,80,90,100 and 100,100,100,100,100 for idle up. However, I am not sure if the dual tail will hold with the brushless setup and those curves. I had to use a direct drive tail to get my tail to hold. If it doesnt hold just use 0,50,70,80,90... even my stock tail would hold with that curve before I changed to direct drive.
