RE: Regulator Voltage
[size=3]I have the same questions about a voltage regulator. Is a regulator needed when using the A123 2-cell 6.4 volt battery for the receiver and servos? My radio is the Futaba 12FG 2.4GHz with Futaba Digital servos. I have the new A123 battery, but haven't used it yet. Will the receiver and servos handle the 6.4 volts OK? If I do need a regulator, which brand(s) are the most recommended? My plane is a Balsa Nova 120 which weighs about 12 pounds. Any advice will be appreciated. Regards JC[/size]

12FG Servo Reversed Itself
Hi Bax and Krysta, This past Sunday with my 12FG, I was ready for take-off....I thought. But when I advanced the throttle for take-off, I immediately saw the rudder had reversed. So I aborted the take-off and went back to the pit area to check everything. I had previously flown another plane with the same 12FG transmitter, so checked to be sure I was on the correct model...and I was. Then I found the rudder had not only reversed, it had gone back to zero on exponential. It had been set at minus 30 percent. All the other channels were right where they should be, only rudder had changed. I reset the rudder direction and dialed back-in the minus 30 exponential. Then I flew the plane 3 flights and everything was normal. I have no explanation for the changes in the rudder function and wondered if perhaps you do. Equipment: Futaba 12FG FASST with 14 channel receiver and digital servos Regards JC

12FG Erratic Servo Functions
[size=3]I have been flying my Futaba 12FG for several months and performance has been perfect. Now, I am installing the radio in a new plane which has split elevators and so has a right and a left servo to actuate each side. I have performed the 'ailvator' mix in the transmitter which puts the 2 servos on receiver channels 1 and 2. About 80 percent of the time, elevator function is normal. But, the other 20 percent of the time the 2 servos don't move in unison. For instance, if I move the transmitter control stick to full up, one side of the elevator will go up as normal, but the other side doesn't move until 2 or 3 seconds later. The throttle servo has also been erratic. Sometimes it's normal, sometimes it doesn't move at all when the control stick is moved. I'm wonder if perhaps this is a voltage issue. I understand the 2.4GHz FASST receivers operate at a lower voltage than previous receivers and that this has caused problems with some servos. I am using the R6014FS 14-ch Receiver and Tower TS160 Digital servos. This combination has worked well in my present airplane which does not have a split elevator. I'm thinking I may need to get something like a 'Smart-Fly Powerbox' to amplify the signal to the servos. Or perhaps the problem would go away if I installed only Futaba Digital servos. Please advise. Regards JC[/size]

RE: Getting back into flying - what radio
[size=3]Dean, I left the hobby in 1981 and came back about 2 years ago. Back in the day, I flew Kraft radios. Kraft is gone, along with many other radio manufacturers. So I decided to go with the radio brand that has "stood the test of time". My choice was Futaba. I now have two Futaba radios, the 7C and the 12FG. (2.4GHz FASST) Many hours of carefree flying time and not one single glitch or malfunction. The performance has been perfect. I don't see how "perfect" can be improved upon. I think all the modern radios are good. You wouldn't be wrong to go with JR, Hitec, or Airtronics. There is also somelthing to be said about choosing the radio that is most popular in your area. Hope this has been helpful. Regards JC [i]I fly twice as FASST[/i][/size]

12FG Exponential Setting Question
[size=3]I'm still trying to figure out how to set up the programming on my 12FGA transmitter. I have a very basic question. I want to use exponential to desensitize elevator, aileron, and rudder functions around neutral. So do I want to set the curve rates at plus or minus? I'm thinking it should be set at +70%. Is this correct? If not, what would be a good differential setting? Thank you JC[/size]

RE: Moki vs Mark
[size=3]Quote: "What is your favorite blend o glow fuel for your Moki engines?" Thanks Capt,n Hi Capt,n I normally run Powermaster 5% with a synthetic/castor blend. The Moki/Mark engines will run OK on straight FAI (80% methanol, 20% castor oil), but it's gooey and a mess to clean-up your airplane. In cold weather it's a real chore to clean the castor off your model. My favorite fuel is 75% methanol, 5% nitromethane, 15% synthetic oil, and 5% castor oil. The 5% nitro will give you more power and improve your idle and throttle response. The synthetic/castor blend is much easier to clean off your airplanes....and it doesn't create as much varnish and gum in and on your engines as does straight castor fuels. If you run your engines in a rich 2-cycle, you'll get more engine life and glowplugs will last much longer. Best Regards JC[/size]

This fact attests to the outstanding performance of this product in the wide variety of engines and accessories now in service. BPTO 2380 is a synthetic oil having a viscosity of 5 centistokes at 210°F that is approved against US military specification MIL-PRF-23699F-STD, DEF STAN 91-101/2* (DERD 2499), and meets the requirements of most jet engines and associated accessories. It is a Type II oil which provides a more balanced combination of thermal and oxidation stability, load-carrying capacity, lower volatility and low temperature flow characteristics than other 5 cSt jet engine oils. These features provide long trouble-free performance under most conditions. Synthetic oils of this type are not all identical. The performance advantages of BPTO 2380 are achieved by careful selection and balance of basestocks and additives to provide the desired performance

RE: Does
Quote: "But doesnt that hot air rise (aka thermal) causing lift?" Since heat causes air to expand, it becomes less dense as it occupies a larger volume and therefore it tends to rise. However, hot air tends to rise unevenly. Often the hot air rises in circulating columns (thermals). This is great for buzzards and sailplanes. But when you are coming in for a landing and "flair", some other factors come into play. When you "flair", your plane will be in a nosehigh attitude, the wing angle-of-attack is increased, total airdrag is increased, and airspeed decreases. Here is where the layer of hotter, less dense, air can ruin your anticipated (hoped-for) smooth landing. A sudden decrease in air density results in a sudden loss of lift, and the rate-of-decent suddenly increases. At this point, let's hope you have a good strong landing gear and plenty of prop clearance. Regards JC

RE: Does
If you are landing on a paved runway, especially a blacktop runway, in hot weather, (especially on a sunny day), the surface of the runway will be hotter than the air temperature. Under these conditions, there will often be a layer of hot air just above the surface of the pavement. This layer of hot air will be greater in no wind/low wind conditions. This layer of hot air will tend to be less dense than the cooler air above it. As air density decreases, lift decreases. As your airplane decends into the hotter and less dense air, the wings are suddenly producing less lift and the stall speed increases. Regards JC

Best JETT for 70's Era Pattern Plane
[size=3]Bob, I flew Pattern competition back in the 70's. IMO the Pattern Planes of the 70's and 80's were (and still are) the best flying of all RC planes. Back then my favorite was the Vertigo II with a piped Rossi .60. I also flew the Banshee (Jersey Jim design), and Bob Smith's T2-A....and of course a Kaos. Everybody had at least one Kaos. So I'm gonna get a Pattern Plane and put retracts in it. Haven't decided which one, maybe a Brushfire. I would appreciate your advice as to which JETT engine and muffler/pipe would be the best choice for this type plane. Thank you JC [/size]

High Torque EP Car Servo Question
[size=3]Hi Bax and Krysta, Is the BLS452 for use only in cars? I am puzzled by the product info on this servo in that it indicates the servo is for use only in cars: "High Torque EP Car Servo" "FEATURES: Ideal for electric cars, truck and boats Metal gears" I fly the Futaba 12FG 2.4GHz and 7C 2.4GHz radios. I now use Futaba BLS451 (Digital-Brushless) servos. Looking at the specs on the BLS452, it looks to me this would be a good servo for use in my larger airplanes. Seems to me this would be a good choice for RC planes. The webpage also indicates: "NiCd use only". I use NiMh and A123 receiver batteries in my planes. Would these batteries be OK for the BLS452 ?
