RE: Meister 1/5 scale P-47
For those of you who have thought about going electric on your gear, thought I would post about a Call I received today.
I had seen the Down & Locked product a while back and saw great potential in it. Hadn't been able to get it touch with them. A friend, already one of their oldest customers, told Mitch, the owner about it, and I got a call today from him. Before I had even had a chance to call him. Very cool. What a nice man to talk with. He couldn't be more passionate about the hobby, and improving what he can in it. This guy is a true inventor. Anyway, the result is, I hope to very soon be sporting his electric conversion in Zombie. Now, what that does for us, besides the obvious elimination of the air system and all that goes with it, is the ability to do a very realistic slow speed (predictable and dependable) and stagger on the gear, and still have the inner doors properly sequenced because of the way his end points are controlled. This will be very nice, as the inner doors are already on servos, already electric, as it were, and easily plugged directly into the sequencer.
I'll get pictures and operational video asap.
I was told the turn around on the conversion runs about 3 weeks from the time your gear hits there facility.
I also talked with him about helping me on some other projects. Very exciting.

You're gunna need a bowling shirt pretty soon,,, 
That came out great

Here is the dummy radial fitted to the cowl and engine. Had to throw the static prop on there for effect.
We have the radial as far back in the cowl as we can go, for more realism. This the best we can do without a prop extension, and that won't happen.
Still some work to do on the bottom cylinder. I'll be adding the push rod tubes and possibly the rocker castings.

RE: Meister 1/5 scale P-47
Well guys, the CJ gear is on it's way to NC to be converted to electric. I'm really anxious to see this and share it with you. If it goes as I think it will, I'm going to convert the new Corsair as well, AND, we are already brainstorming the 12' P-47 Sierra gear. I may never need to build in air again, and that is a very appealing thought to me.
If all goes well, we are thinking about providing jacks for Zombie at Toledo, so we can cycle the gear for anyone that may want to see it work. Maybe we could make something similar to what they would have used in the day, to test full scale gear.
I also have the R-2800 permanently mounted in the new cowl, so the working cowl flap project can move forward. I'll have some pictures soon.

Ok Gary come clean, the training wheels are actually so you can pull the plane down the road and not have to load it in the truck
I spoke with those guys last summer at Down and Locked and I was supposed to send mine in last September but decided to give it a while to see how their success goes. So with that being said you are the guinnea pig! I've been burned on too many new releases. So if you and Dave Pederson fly all summer with no problems then sign me up!!!!!! I went ahead and put my doors on servo's so if I do go electric I won't have to fuss with the doors still on air.

I need to go on a diet. Anyway, I have had several very interesting conversations with Mitch, and his knowledge of the subject is impressive. The guy is very forthcoming with technical explanations of how his gear works. Did you know that he uses a 'transmission' to reduce the motor from the 20,000 some RPM armature speed to a very torquey shaft speed? His electronics is designed by another man (Ron) that is his electronics expert. They don't control the end points with mechanical devises and rev. counts to wear or come loose. It is all built into the electronics. His shafts (stainless) are all going to have a baked on anti-friction coating that will virtually eliminate wear. It's been tested to thousands of cycles with 0 wear. This will make for very consistent operation. He calculates each gear to 3 Gs in weight (the weight of the struts and tires on a pull out) and figures his torque requirements accordingly, with reserve power. That is why you send him everything.
All this in a package of less diameter than the present air cylinder, in most cases including mine.
He is retired from drag racing (26 years I think he said), and his machining and engineering experience gave him the knowledge to do all this, once he had the time to put his mind to it. He has been an RC builder and pilot all along, and himself, never was satisfied with air systems on retracts. "necessity is the mother of invention" they say. He came along at just the right time, I would say. We have the technology.
He also has his own sequencer now, but Brian had already done the brain surgery on them and ordered one. Came this week. I forwarded the info to Mitch for his electronics geek to evaluate.
This stuff is all invented and made right here in the States, as is the gear he converts. Pretty cool, if you asked me. Dave Brown would be proud.
As you can probably tell, I'm pretty pumped about all this. I have had one belly landing (at the Monster Planes event) with Zombie already in just 40 flights, due to air loss. Looks like that will be the last (due to air loss
). We have 6600 MAH of battery on-board Zombie. I don't see running out of juice.

RE: Meister 1/5 scale P-47
OK, here we go on the cowl flaps. I'm following Wayne Fossils lead on this one. Two things I am doing different are (1) using two medium size Du-bro flat hinges on each, instead of the large ones (my thinking is they may work easier on the slight curve with out binding), (2) I am using two full size servos instead of mini ones. Everything else is the same. His procedure is very easy to follow.
1. mark the location of each flap on the cowl
2. cut the entire flap section off leaving them attached to each other for now
3. mark and notch each hinge into the cowl ring
4. glue the hinges into the ring while it is in place (I used Tite Bond for this step as you can be liberal with it and it will not glue the hinge joint itself)
At this point, the hinges are all in place, and the ring is tack glued to the cowl.

RE: Meister 1/5 scale P-47
More progress on the cowl flaps. Everything is tacked in place now. It works great.
5. I taped the flaps back in place
6. put a drop of oil on each hinge to keep them from accidentally being glued fast
7. glued the hinges to each flap
8. ran the control cable around the inside gluing a 3/4" section to each flap
9. pulled the cable back out
10. cut each flap loose
11. reinstalled the cable
Now I need to do the final gluing with my Hysol epoxy, add the 'feathers' in between each flap to fill the gap when they are open, and that is it.
This is so easy, it is scary. Thanks to Wayne, Dino, and the Meister bunch.

Hey Wayne, i think that meant '' Jeff send me a cowl and I'll be glad to do it for ya!'' You read that too huh?? Come on Gary all that free time you have between the corsair and the GIANT 47 I think you can squeeze me in.

Nope........Didn't read that at all.
Jeff, I don't think you would have a problem. If I can make them work, anybody can
