This will take awhile as I have many projects at my studio but at least it's upstairs laid out on the board with all components ready to build.

I ordered the kit directly from Sig and as in the past they were very responsive and got the kit right out to me even though I wasn't in a hurry. These people actually right to you personally and tell you what's going on with your order. Amazing. There are several companies RC and Free Flight that do this, Volare Products comes to mind and some of the other cottage industries here.

I'm using a Rimfire 250 I had laying around, 4 HS 55s and a 2 cell 450 for the guts. I have a spectrum RX as well. Should be a good combo for this 25 inch span bird. It has a roomy fuse.

It will have ailerons, rudder and elevator. Removable wings for transporting and possible repairs. Servo for both ailerons.

I plan to add lots of scale details such as the radiator grill and a detailed cockpit.

The reason I decided to RC this plane is so I have something to fly indoor and outdoor anywhere I can find a parking lot or patch of dirt or grass. Where I live there aren't any RC fields or good FF fields close to me without taking a good long drive.

The kit is outstanding and the laser cut parts just fall out of the wood. It comes with red and black tissue but I'm going to take the plunge and print my own Lozenge on Esaki tissue. George Bredehoft has been helpful in pointing in the right direction, thanks George

The kit showed up in 3 days well packed and in shrink rap.

Opening it up was a delight of well packed plans and parts.

Twp sheets of plans. Very old school. I like it.

Very good selection of wood I don't need to replace anything

Rimfire fits good.

That would be a nice model Steve. I guess you are considering flying it rudder/ elevator/ throttle which should work well. I'm a little surprised though that you are using HS55's as although they are good servos - they may be a little heavy.

Everything else looks Ok to my eyes anyway.

I fly a 36" EFlite Piper LA4 on 3g servos although I have 4 in the model. It also uses a 2s400 and the recommended EFlite Park 250. It weighs around 10oz ready to fly

These are the servos I used

Happy flying.

Actually I wrote that I will have ailerons too. I'm taking the dihedral out. This is all based on a previous successful build by a gentleman in Austria who posted a thread on RC groups: https://www.rcgroups.com/forums/showthread.php?1285823-Fokker-D-VII-%28Herr-Engineering%29-Conversion  I'm building mine the same and the HS-55 ingeneral I use for planes in the 24-36 inch span.

I should be fine. Thanks for you input OZPAF!

I've done a lot of these gummy band to RC convertions. As a general rule I like to add over-sized ailerons. This allows me to use less deflection to get the roll I need. These small ships really do present a lot of adverse yaw. I also make these full house and couple the rudder to help address adverse yaw. I think you will want  3 axis control. I think I go into a bit of detail on this in my Dumas P6-E and Guillow Champ threads.

A little progress. Only a couple of hours but I tell you this Herr kit just builds itself.

I'm using the balsa cowl as a vacuum form plug and tomorrow I'll point it up and add scribes to define the radiator.

I would move the rear rubber peg up one set of uprights.  Of course, if you are going the rc (never capitalize  Wink) route, it doesn't matter.

Yes rc. Wink I have plenty of FF to maiden and trim when we get our flying site. So I'm making a few rc versions to fly in a few places I have locally. Of course the sites are public and signs say "No drones" but this is not a drone;)  During the week there are no people there.

Understood.  I'm contemplating an E-36 with rcdt as a fall build so I have something to play with in a small field near here.

Makes sense the best of both worlds in a small field. Brilliant.

I got that vacuum formed cowl made today. All I did was take the balsa cowl they have you make and I scored deep panel lines into it with a standard ballpoint pen. Vacuum formed it and cut out the radiator area and filled it in from behind with a bit if insect screen.

I got the tail feathers made and I'm just starting the loser wing.

Have you decided on a color scheme?  The Hermann Goering DVII was all white.  That was back when he could still fit in a fighter. Grin Grin
