Electronics for the Intrepid gasser

[Ciprian]

Guys,

I want to get me a gasser and I wonder what electronics you use in yours. I won't do any 3D, just slow, easy flight. Please post your setup: receiver, servos, gyro, governor, battery, switch. Also, what kind of redundancy systems are you using? I just hate the thought of a big flying lawnmower to get out of control because of a failed switch.
Thanks.

On my EB for AP...slow easy flight, too.

Futaba 149DP
9252 on controls
std on throttle
401
no governor
Duralite 4000mah with HD switch/regulator

Redundancy? In failsafe, my AP2000i will help bring it down with stabilization. Not sure if that's what you mean.

Mark, I am talking about like 2 switches, 2 batteries and stuff like that.
Thanks.

My equipment:

JR 649SPCM receiver
JR 8311 servos for surfaces
Futaba 611 gyro with own rudder servo
Low cost standard servo for throttle
Futaba gv-1
JR 1400mah battery backup
Jewel on-board generator for main power

For power redundancy the jewel is the best choice in my opinion. Beats any battery pack because it offers unlimited power for the machine to fly and the battery is just for backup purposes in case the engine quits, otherwise its charging while you fly.

looking in the the Duralite Gemini system

some of the features

Quote-----------------------------------fromthe their site

• 2 independent micro controllers for complete redundancy
• 2 connections for attaching 2 batteries
• 2 high output 15 amp regulators
• 2 - 5.9 volt out put leads for RX
• 2 - high intensity low voltage LED's
• Output 5.3 lead for the gyro tail servo
• Remote fail safe switch w/separate arming for each battery
• Low voltage memory
SIZE: 70mm L x 29mm W x 10.5mm H
Available mid March

Is the Gemini a Power Box? It has some of the features of a power box but in miniature. Due to the fact that it is designed for helicopters and smaller aircraft it does not need pulse amplifiers. It does however offer 2 different voltages 5.9 volts for the servo's and 5.3 volts for the gyro. This is useful for helicopters and jets. It is capable of 15 amps or 7.5 amps per side. It has LED's for voltage monitoring It has a rugged purpose built failsafe switch with power on lights and low voltage warning strobe lights. It also has a low voltage memory the same as the Power Box.

PRICE: $146.95 US

Hey Ciprian...the info you are getting is good stuff...

when you decide give me a shout back if you have any questions...PM me if you dont have my number anymore...

I am interested in getting more data from the guys running the DX7's...I have one that I am planning on using in a prototype Bergen electric Observer EB I will be starting soon...

Does that Duralite gemini system even come with batteries, or do you have to spend $90 a battery x 2 as well:

GEMINI DURALITE PLUSTM Batteries


Click to enlarge
#7164pGEM: 1600 mah - GEMINI 4 cell li-poly
7.4 volt - Redundant, 2s2p
Comes with two leads including one 12in 22GA pig tail for charging w/yellow connector and one power output lead 12in 22ga wire with black male JR connector
Max Discharge Continuous - 20C
Flight weight: 2.8 oz
Size: 1.375 x 2.75 x .75in (L/H/W)
require 2 batteries to power each GEMINI Module

PRICE: $89.95 USD

What about the charger and the tester and the rest of the package that they sell you to maintain it all? Sounds like you might be looking at a system that is close to $400!

I prefer my system as there are no batteries to charge and maintain really (you can use a $15 battery, and you can go flying anytime anyday as long as you want!

Here is a link to my website for my pictures:

Not as fancy looking as the duralite pictures, but at least you get the idea! :)

Greg,

Still have your number.

Thanks.

Ciprian, I'm using:

JR 649S PCM receiver
3 JR DS8311 servos
JR 537 servo - throttle
GY401/9254
6V Duralite regulator
Duralite voltage step down
TBM 4-cell Li-Ion battery pack
Revolution base-loaded antenna

The 4-cell battery pack is like 2 2-cells for reduncancy there. I always checked my battery voltage before each flight so I would know if something funky is going on with my battery system. I'm also using a heavy duty switch. I don't use a governor, just a good throttle curve setup. With the help of Chris Bergen and Gary Travis, it was quite easy to pick up and understand how to tune and program the curves.
