it is a tad too orange by my eye, maybe just needs toning down a bit! fantastic looking engine though!

I think it looks pretty good. You could always weather it a bit to change the shade and dirty it up.

Add a wash of silver, then another thin one of black and it might turn out very nicely!

I didn't like it at all, I just gave it a coat of satin black but I have to go to the LHS tomorrow so I'll see what they have in a spray can, maybe like a burnt metal or something. All I have here is Testors enamel and I don't want to brush another coat on.

Hi dglo,

I just found this thread!!. exciting subject you got here.

I scratchbuilt a 43" wingspan Jungmeister and I couldn't ge happier with the results...although I haven't flown it lately I did fly it many times very much to my satisfaction.

I'm attaching three photos of mine and a link to my thread post the day of the maiden flight in case you wanna check it.

I will be following this thread closely...can't wait to see your flying!!.

Gerry.

dglo,

Gerry has done a super job on his Bucker Jungmeister and there will always be experimentation with power system and perhaps propeller selection there is a few power system improvements at:

Also, check out some wonderful pictures from our David Hart (RC and Real Warbird Photographer) took of Gerry's Bucker! A little about David:

Nice looking Bucker Gerry, very nice flying too, hard to believe that was the maiden flight, looked very smooth.

Went to the LHS today and picked up some odds and ends, then repainted the exhaust with metallic copper, and dry brushed some flat black to dirty it up a bit and am much happier with the result. Movin on. Want to get the motor and cowl mounted next then I don't know, maybe start covering? Still a lot to do.

The exhaust ring looks much better now To add a slight metallic look, I rub on a tiny bit of pencil-lead graphite - just enoug to give shine. But it also accentuates any roughness in the finish.......

Question: The more I research the subject, the more confused I get. Should I install a seperate switching bec? I'll be using a scorpion commander 70 amp esc with a 5v 4amp linear bec on 3s lipo. From what I can figure out this is kind of borderline as to wether to use a seperate bec or not. Any help? I'm using 2 Hitec HS635HB servos on elev and rud and 2 HS225BB servos on the ailerons.

Thanks,
Doug

Yes, yes, absolutely yes. Linear BEC's aren't the greatest to begin with. Definately install a switching BEC, or use a separate battery pack for the receiver and servos.

Thanks for the timely and definitive response Frank. All my other electrics are 2s and it was never an issue before. Just ordered a Dimension Eng. Sportbec. If I'd thought about it before I should have ordered an esc with a switching bec, probably would have been about the same price and an easier install. Live and learn.

There is a degree of redundancy in having them separate. If your ESC fries, then you still have power to the radio with a separate BEC.

Doug,

I use separate Battery Pack with switch Harness for my larger Glow-To-Electric conversions. With the External BEC providing power to your servos and most importantly Receiver, you are still dependent to your Flight Battery. I can tell you a few of my RC Flying Buddies learned the hard way that yes, even though you have a very good quality External BEC the changes are that if your Motor gets into trouble (like throw a magnet 'or' worse a winding snaps and gets jammed with the rotating housing - assuming outrunner) your ESC will blow and at times your flight battery contacts as well due to the large back EMF of motor all of a sudden stopping.

With any high energy power system beyond 3-Cell Li-POLYs, I like to go completely separate and use traditional GLOW setup and use Separate Battery Pack with switch hardness to power the Receiver and Servos. The ESC will be used just to control and provide commutation to the Power System so, and all you have to do is take out the RED Wire pin from ESC before you hook up to Receiver assuming you go separate Battery Pack setup. This way, no matter what happens to the power system you will still have complete control over your model.

Just my 0.02 Cents worth.

Thanks for the input Frank and Pitt. In my way of thinking, I like to keep things as simple as possible, in fact some say I'm simple minded. I think you could probably apply enough redundancy and "better safe than sorry" measures that this thing would weigh 15 lbs. Believe me, I'm much more likely to have a crash due to pilot error than any kind of malfunction. Besides, I only fly these planes so I can justify building them
