Looks like you are about to the point in building a homebuilt we call 95% done and only 95% left to go!

Same applies in software development -- the last 5% takes 95% of the skullsweat and effort.

There's also something from IBM called the Waterfall Principle -- essentially, the development process is like a river with a waterfall (the waterfall being being release to production). the further upstream changes are made, the easier it is. But when you're over the edge of the waterfall..... tons of effort.

Looks like you did a massive effort on skullsweat way, way upstream. Nows, it's just getting everything put together.

Dag. Take your time, and don't sweat getting slammed by work. We all like you and won't get bent out of shape if this project takes another year for completion.

Hey all......

Been a very busy week for me. All I have gotten done is a bit of work done on my radio lay-out.

I like the idea of remote RX's in the wings, but one of the most important targets to hit on this project is making sure my CG hits where it needs to be. To date I have not had to add ballast to my designs to get the CG correct. With all my A123 in the nose my CG should be very close, how ever if I have the RX's in each wing and the 2 A124 per RX's that would be 4 batteries in each wing, and then 4 in the nose. Each outboard wing has 2 flaps and 2 motors from RX1, and 2 jet motors and lights from RX2.

While the remote RX idea may be a good one, it may not be a practical one.

This was PM to me:

I believe with 3 RX's and 3 of these I can easily cover all my systems.

Rock ON!!!!

Hi DAG,

Here is the same product available in the US:

http://www.globaljetclub.com/index.p...roduct_id=1434

Or here:

http://www.sincityjets.com/store-powersystems.htm

What would dropping to 6 receiver batteries do to your CG?

Are you still interested in having standalone systems in the outboard wings (i.e. nothing electrical to plug-in during assembly) or has the CG problem turned you off of that idea?

Hey buddy,

First PM my a link for the E-scooter you guys had at SEFF

I am having my ideas run down many paths right now.

If the OB-wing has its own (2) RX's that will require 3 batteries. 2 batteries for the RX that runs the 2 flaps, 2 motors, and aileron. The other RX is for the jet and lights. If the battery were to fail on the #2 RX all I would lose is jet power and the lights, no big deal.

If I lay it out as my original design I would have connections for these systems:
Option #1
Motor #1 (ESC)
Motor #2 (ESC)
Flap #1
Flap #2
Aileron Servo#1
Aileron Servo #2
Jet ESC's
Lights.
That is 8 connection.

OR!!!!

Option #2
Place RX#1 for flight systems in OB wing
Place RX#2 for Jets and lights in OB wing
Place 3 flight pack batteries in OB wing
And may have CG issues....

OR!!!!!!

Option #3Which I am liking more and more as I look at it
I could put all the RX's in the wings and run 3 wires back to the 3 OB wing batteries in the nose and only have 3 connections and keep my CG safe.

Just a designing fool right now.

DAG!!

Thanks!!!!!!!

As you can see I am in a dark place trying to get my head around this.

I hope by next week to have most of this figured out as I am getting to a place where I have to pick a direction and go, plus I am getting ready to drop another $2-3K on radio stuff........

Rock ON!!!!!!

Right now I work 95% for a company based in Rome, 50% I work for myself, and about 75% I contract for a few other companies. Wait, that's more than 100%

But..... I plan on selling off about 4K worth of stuff over the next 5 months to off-set my new radio gear.

Rock ON!!!!
