I must have missed it, but what is the diode for?


Let's see if I can get this right.....
For our purposes here, power going through a diode is dropped by a little less than 1 volt (1 volt for planning purposes). Power through 2 diodes drops a little less than 2 volts (etc.). We're using the diode to limit power from a fully charged battery pack (7+ volts) to that found safe for use with the 6 volt max limits on the ignition modules. Works great in practice, and can't get much simpler.

Status: offline 		I currently have a DLE20 in a OMP Fusion. Very nice but one day down the road it will no doubt meet its end. In looking for a replacement plane for the DLE20 I came across a Phoenix Model 540 Edge (.90- 1.20 size) at Tower Hobbies. It is a 65" wingspan and AUW of about 9 pounds. I did a search here but there is no information about this specific plane. Does anyone have it and can report the quality of the ARF and how well it flies?

Thanks
Mike

Hmm never thought to use a diode to reduce voltage, always used them to filter voltage or rectify AC to DC.  I know a Zener diode has been used for regulating voltage though.  When I played with electronics, I used a voltage regulator to do it, has 3 legs, one as input, one as output and the third to ground to bleed off excess voltage. Of course it had capacitors and diodes too.   

I used diodes also to setup wigwag lights to prevent positive voltage from bleeding from one light to the other on a common ground circuit in a car.  Never tried them to reduce voltage though, will have to dig out my box of parts and see the drop for myself. Interesting.

The voltage drop is load dependent but I found it to be about .8 volts on a half amp load.

Glyder. Excellent. Please post your impression of the plane once it has been flown.

I have the DLE 20 in my TF P-47 and GP PT-17. Good fit and good power! I used a 17x6 Xoar in the PT, and a Xoar 16x8 in the P-47.

Had 2 flights tho....
Looks great, great cockpit, tad heavy, easy to fly....
The extra260 or the Edge 540 are better for 3D.

Hi Lifer............I'm wondering..........I'm using the Dubro Vibration mount in the PT17 and I'm having to hog out a bit of the triangle stock on the firewall for it to fit........did you do that or just use the stock mount. I made a drill template based on the Tower instruction manual and am going to drill and mount the mount today.

Status: offline 		Oldtyme,

I really like the H-9 metal mounts. I used those and added spacers to project the thrust washer to where it needs to be. I would like to discourage the use of the soft or vibration dampening mounts. I believe that it is best to hard-mount these engines. Just my 2 cents.

Status: offline 		After over 300 flights on my 2 DLE-20's, I now have the first Mintor 22cc in the US.  My friend Matt and I are building the ultimate 68 inch Velox. We found a NIB yellow Velox from CA. Matt has contributed the Hitec 5565 ultra fast HV servos on the wings and elevators, and a 7954 on the rudder with Azhars's cool Secraft CNC servo arms. We are using CF/Ti pushrods, 10 oz Fiji bottle tank, Tech Aero IBEC, JR922 DMSX receiver, with dual 1300 mah 20C Sky-Lipos for power, Nachos cheese graphics. The Mintor 22 hopefully swing a 18 inch Vess. This will be the ultimate cool Velox, best of everything.  It will be very interesting to see how it performs compared the trusty DLE-20.

Status: offline 		No pictures at this time and all the planes are buttoned up. If I need to remove the cowls, I'll take pictures at that time. Given the fact that the DLE's are purpose-designed model engines, they really don't have a different appearance than a glow engine.

Status: online 		Here is where my dle 20 is a. In my cmp butcherbird. I did a 5minute spray bomb paint job. I hide the on off switches under the panel on the side. The cowl has 4 pegs on the ring that index it to the fuse and 2 rare earth magnets hold it from going anywhere. One more pic of the magnet and index holes that the cowl goes into.

Status: online 		Here are a few more pics. I wish they would have slanted the plug back. It seems like it would have helped getting the cowl to hide on some of the birds like the P51 where the cowl curves up on the botrtom. Mine is sticking out, just the plug cap maybe 1/2 inch tops.

Status: offline 		I know this was covered briefly in earlier posts.......way earlier.........but I'm an old guy trying to learn new tricks. When you rotate the carb 180 do you or should you rotate the reed block as well or just the carb??

Thanks for humoring an old fart.......

you only rotate the carb, the reed block orientation is specific to the crank case in how it draws in the air fuel mixture. At least that is how I understand it.
