Well the outside is nearly finished. Added some decals and balanced the plane laterally (wing tip to wing tip).

Finished painting the wheel fairing and adding a black step strip to each side.

Well Cub Yellow Monokote is not what it use to be. The color is not very dark and it is somewhat translucent (i.e. I can see some wood grain. But is still looks pretty good. Here are a few pictues with the red strips on the wing. Still need to add black walking strips and paint the wheel fairing .

Well, the job of completing the cockpit and installing and painting the canopy is finished. The hardest part of the job is masking off the canopy before painting. Below are a few pictures.

Finished covering most of the fuselage. Below are some pictures.

Well I'm finally getting around to finishing the AT-6. Below is a picture of the cowl and dummy radial engine with a 91 OS four stroke behind it. It looks better than I expected. I currently covering the fuselage with monokote so I should have a couple of pictures of that by next week.

Its been almost two years since I started the Topflite AT-6. Well, construction is pretty much done now. Full flaps and retracts. The engine will be a OS 91 four stroke. Not sure if I will get it cover before the flying season since I have a Goldberg 40 size Anniversary Cub I need to cover first. I have a picture of it below.

Here is a picture of my B-17 coming in on final during our Memorial Day Flyin.

It been a while since I provided an update on the AT-6. The wing is essentially finished except for building the flaps. I decided to postpone the flaps and start building the fuselage. Overall it is a reasonably simple build but there were some steps where the instructions lacked a clear description and pictures, especially on how to finish off the top turtle deck/ tail section. Anyway, I did a little guessing and feathered the turtle deck around the verticle fine. It may not be scale but it looks nice. Here are a few pictures.

My son and I just completed a modification to his Futaba 8U. It has been Spektrumized with a DM-8 Spektrum transmitter module, however not in the way it was originally designed. In this case, instead of using the awful looking add-on Spektrum antenna and external RF cable, we use of a Frsky 2.4 antenna and some fancy internal wiring. Below are some pictures. Note that there is no loose RF cable external to the case and the antenna fits nicely out the top. Also, I added a bit of shrink tubing around the RF cable to avoid any contact interference. The last pic shows the spektrum module inserted into the back of the 8U with the frsky antenna stick out the top. The Spektrum and Frsky antennaes are the same size and rating and the connector type used on both RF cables are the same. And yes we had the module for less than a day and voided the warranty by drilling a hole thru the back of it.

During the Christmas holiday I was able to get a little more work done on the AT-6 wing. I was able to add the air control valve and air tubing for the retracts. I also sheeted the top center section and fitted th ABS wheel cowling to the wing. I included some pictures of these activities. With respect to the air control valve, as you can see it is mounted behind the wing spar. I added a hatch on the bottom of the wing so that the valve and control servo can be removed for maintance.

Well its been about a month since I last updated this blog and I would like to share with you the progress I have been making on the AT-6. For the most part, the biggest hurtle of builing this plane has been finished, that of building the wing with the correct amount of washout on both sides to help prevent tip stalling. During wing construction, I elected to build the wing with the option of split flaps and retracts. The flaps on the AT-6 use two servos in the outer wing panels to pull the flaps down. One unique feature of the AT-6 flaps are they go from a portion of the outer wing panel and all the way across the center section to the other outer wing panel. What that means is the flaps are also effective under the fuselage. As for the retracts, they will be the old Rohm air system with the air tank and control valve built into the wing. Below are a series of pictures that show the wing build from ribs to almost completely sheeted. The last picture show the 2 degrees of washout that is built into the wing tips.

Well a new winter is approaching and it was time to start buiding a new plane. After thinking about it for awhile this summer, I decided after the scratch build B-17 that I wanted something a little easier. So have mauling it over for awhile, I decided to build the discontinued Gold Edition Top Flite AT-6 I bought 10 years ago. I have decided that the plane will have scale flaps and retracts with careful attention focused on keeping the wings true with the identical amount of washout in each side. The washout is important for the AT-6 because I think a lot of builders forget this and the result is a snap happy model. The plane will have a wing span of 69 inches and will be powered by a OS 91 fours stroke. I hope to keep the weight to about 8.5 pounds. So far I have built the tail feathers and center wing section. Note that the retract air tank is built into the center wing section. Whenever I can I build the air tank into the wing in order to eliminate air line connectors bewteen the fuselage and wing. Below is a couple of pictures of the

Here are a couple of snapshot that I took from my B-17. The video turned out to be crap due to camera vibration, but I was able to salvage a few stills. One shows me standing on the ground controling the plane during a flyby. The other two wer take from about 400 feet showing some landscape in the background.

Here is my latest video of my B-17 flying. I mounted a camera to the wing tip to get this effect.

Finally, the maiden flight of the B-17 happened on Thursday evening. It flew very scale like. Here is a video link of a flyby.

I've been using the Frsky 2.4 sytem on my Futaba 8UAF for about six months. It works great for my small electrics and heli. The only downside has been the annoying antenna coming out of the back of the module. Not a huge deal, but I wanted a cleaner installation. Anyway, I decided to clean it up a bit by having the antenna come out the original antenna hole. I first order a 200 mm RF cable from Frsky. Next I found some plastic tubing that I could get the clip end of the cable through. I did this so the RF cable would be protected. I bent the tubing with a heat gun, threated a nut about 1/2 inch on one end, painted it black. I then removed the back of the transmitter, drilled a hole at the right position. I wrapped the antenna base with a little masking tape, and forced it from inside out into the TX antenna hole until it was a nice tight fit. I routed the antenna cable through the bent plastic tube and into the back of the module case and threated on another nut on the inside to hold the tube tightly (note I had already removed the back of the Frsky module and removed the original antenna and unclipped it from the module's electronic board. Now after routing the longer RF cable from the antenna, through the TX hole and plastic tubing and into the back of the module case, I clipped it to the module's board and reassembled the TX module. Then after a little trial and error to get the tubing the correct length so it goes just inside the TX case. Be aware, that if you drill the hole to low, you end up being on top of the speaker which is why I did the trial and error fitting at the end. Anyway, below are a couple of pictures to help you see what I did.

I have tried many times to post videos directly to my blogs, and always I'm told I can not add videos here. Hence the reason I have links to the gallery. However I see several blogs entries with videos attached. How are you able to do it?

Although I have 3-4 years from retirement, I have already started to think about what I will be doing aftewards. The pictures below should give you a hint. And no, they are not for sale, unless I kick off and my wife decides to liquidate. In second thought, I think they will be burried with me. (Ha. Ha)
