  Nice work Simon!
 Isn't fun building with balsa!! ;)
Building / Construction / Build class this Wednesday, Feb 26 2020
« Last post by Frank v B on Yesterday at 09:16:09 pm »
Don't forget to attend the coming Build Class this Wednesday, Feb 26, 2020.  We  are slated to go downstairs for 7 pm.  Join us for dinner or a drink before-hand.  Some of us get there just after 5 pm.

Bring your questions, observations and insults. ;)

Here's hoping:
Michael can bring his Snapdragon floatplane project.
Simon brings his Electric Lightning.
Rob brings his Widgeon and Joy Stick
Guy brings his Minima.  At a 101" it may be a Maxi-Moa.
DavidK sends us an alligator from Florida. ;D
other members or surprise guests (Piker?) show up with projects.
I will bring my Stinson Voyager (100 sticks) and Joy Stick (now finished).

Wing construction:

First major (not so terrible though) problem with the kit. 2 balsa strips (24" x 3/32" x 1/4") were missing. I had extra scrap lying around, so I was able to cut strips, but this was annoying and inconvenient.

I built both wing halves at the same time, making sure specific parts were built correctly for the right and left sides.

I followed the instructions carefully, but not careful enough. I still installed one of the servo-bay-openings upside down. I was able to cut it out and re-glue it in properly, so I remind anyone interested, dry-fit over and over, and make sure it matches the plans and instruction photos, before gluing.

(The photo of the aileron servo opening shows the correct positioning; plywood face up to the inside of the wing.)

Anyway, basic construction of both wings took about 3 hours. Sanding is still required, and the ailerons have yet to be built.

The 9g slim wing servos for the ailerons  showed up yesterday. I originally ordered 9g waterproof servos for the model, but the wing tapers and where the aileron servo mounts, the wing is thin enough that a reg sized HK 9g servo won’t fit. The slim wing 9g fits nicely...hopefully Corrosion-X will waterproof it. ???

I haven’t decided whether to put the aileron pushrod on the bottom or top of the wing. Recommended is on top and the opening for the servo arm seems less likely to admit water if the hole is there, BUT, I’m still tending towards putting the pushrod and servo arm hole on the bottom so once water gets in, it can drain out. I’ll add some pushrod/servo arm fairings wherever the hole is cut...thoughts appreciated...

Hand cut and glued the 1/16” ply wing saddle to the matching depron piece.
Speaking of depron, my inquiries indicate depron is getting very difficult to find in NA...anybody confirm or refute this? ???
Didn't want you to think I was slacking off. 

Starting to cover the fuse.

Oh, yes.  At the last Build class it was decided by the group that this should have landing gear.  I was prepared to build it as a hand-launch.  Had to modify the design because.... if built per plan, the landing gear would have collapsed every take-off and landing.  Poor design.

Photo 96 shows the landing gear on the plan and the bend I added to it (red dotted line).  This extra bend sits in a slot cut into the middle of the landing gear block.
Photo 97 shows where the extra bend comes through the fuselage.

beautiful Simon, good job.
Wing center-section.

I built this following instructions very carefully. While it was not difficult, it took me more than 2 hours. I fitted (and sanded if necessary) each piece carefully, before gluing. The parts-fit is precise, but I had to check and double check each joint to make sure I got it right. As long as read and followed the instructions, it went well. There are several plywood pieces in this assembly.

Thanks Rob,
I am particularly interested in learning how to do differential thrust as the Beriev beer bomber I’m building in another TEMAC thread will use it too. I’ll post my progress when I get home.

Hi Bill,
Setting up differential thrust is not difficult, it requires either reading the DX9 Manual, or doing what I did and simply find it on Youtube. Here is the video I used and it worked perfectly.  Just copy and paste it and it should work.


The motors used were Rimfire 400s. The harness that comes with the kit has the bullet connectors already attached so after you have fished them through the wing, it is a simple operation to attach them to the two 30 amp ESCs in the nose of the plane. With one hand you hold the wing with the dangling 6 motor wires and 2 aileron wires a few inches above the wing saddle. They are not long so you must hold the wing close to the fuse. Then with your other had you reach in and get ahold of one of the female bullet connectors on the ESC. Then with your other had, you pick up pliers and grab the male end that is dangling. Then with your other hand you get a second pair of pliers because there is not enough room to get your fist in to really hold the female connector. At this point you will find that the male connectors need to be slightly squeezed thinnner in order to fit. You will not figure this out until you have tried to force the connectors together, dropped the pliers inside the plane twice, called Great Planes, Widgeons and your idea to built this thing by names that you did not know you had the ability to think of. You finally will get it done and the aileron servos connected to the rx, and then you will read how easy it is to transport the plane by taking the wing off, and simply connecting everything at the flying site again. I am pretty sure I am just going to glue the wing bolts in, as I swear I will never take that wing off again.

You need a 5 or 6 channel rx, 5 if you just want differential thrust, 6 if you want separate ailerons. As mentioned, I did have one of these planes previously. You will find with the differential thrust that you will not need the water rudder at all. Just be sure to go the extra step and put the mix for it on a switch so you can turn it off before flying.

The plane looks great in the air and taxiing, although it taxis better with a little throttle on so it is on the step. It tends to plow through the water if you try and taxi too slow. I have used Corrosion X to waterproof everything. Also, the forward hatch is supposed to be held to the plane with an included rubber band. I replaced that with a short piece of cable as I figured the band would have a limited life span.

Let me know how you make out Bill. Maybe we can meet next summer in Port Perry one day.


Fuselage construction is done. Tail is fitted in the slots but not glued (until after covering). It can still use an overall light sanding.
