Well guys getting close to the finish line, here are a few more pics of my detail, just had to do the fender on the nose wheel!!!!!
Struts on the tail feathers took most of the morning, drilling and inserting a threaded 4-40 sleeve in the fin and 2 in the stabilizer.
Fender on the front strut was an after thought, had a piece of 3" sch. 40 pvc pipe ( ID 3" ) turned it down on my lathe to get it thin,
then cut to size that looked right, tapped bottom of strut 4-40 and attached, bent 2-56 rod for fender stabilizer bars. Now got to
disassemble everything solder the strut end and fender bars, paint and put back together. Hopefully get to maiden it next month
if the rain will ever stop, our flying field is very soggy right now.

Not the quickest revamp of an ARF, went back and looked at the time line on this thread, I rec'd the kit on 9 / 08 / 2013
and finally have it finished and flight ready today 5 / 01/ 2021. (7 years, 8 months ) Will be test running the engine tomorrow,
weather permitting. First flight weather permitting mid to end of next week.

Thought I'd put up a couple of pictures I took tonight of my progress so far. Not a scale paint scheme and while it's close to the original covering design of the ARF, it's a little different. Not really much covering left to do, I'm just a slow poke and it's been hard to keep my motivation up. Still need to order matching paint and clear for the cowl. The cabin door will be trimmed out to match the fuselage trim.

How did you end up hinging the door? I did mine in the same heat shrink film I used to cover the plane.
My "ON - OFF" switch is accessible by removing the front cabin hatch & windshield, keeps the outside
lines "slick & clean"! I decided to wait to do any type of interior detail till after the first flight, if all goes
well and it flies good then I will install a pilot and a couple of sperate more scale looking front seats.

First flight was to be today but had to take wife to doctor, rescheduled for Saturday. Wish me luck!!!

Hi Bill, Don't know how it will hold up but it's better than stock setup, I bought hinges that were very similar to what came with the ARF. Used 3 hinges on the door. They look like this:

https://hobbyking.com/en_us/hatch-hi...en_us_products

The flat fixed part of the hinge I cut down and drilled a hole on each side of the center arm and used no 1 sheet metal screws to hold that part of the hinge to the door. The hinge side of the hinge I mounted to the inside edge of the door opening with no 1 screws also. I'll get some pictures of that when I get the door permanently mounted.

The colors in the picture are a little lighter than what they really are. I used Monokote Missile Red, Monokote Insignia Blue and Monokote white.

Hope everything goes well on the test flight!

Dan

Well bad news for the first flight, our flying field is temporarily closed due to the heavy rains
we have been experiencing in our area, field is saturated as is the road into the field. Was.
told they hope to re-open the field by next weekend if not sooner, depending on the rains
coming next week. This has been the wettest April (almost 27" of rain) and May ( 12.7"
of rain) so far this month.

Hi Bill,

I'll see if this video works. Tried to make a video on my door hinge. Video quality is from an old phone but I think you'll see how I did it. In the first video I said they were machine screws but they are actually sheet metal screws.

You need a door handle take a look at mine, bent it out of 3/32" aluminum wire over pliers and
cut to length for installation with epoxy.


BTW nice door hinge technique, looks like you rebuilt the door out of thicker material,

Hi Bill,

The last 10% I have left to complete on this plane is taking more time and I guess it's because being picky slows things down. I have just about all the covering done. I ordered paint so I can repaint the cowl and I think I'll paint the trim on the windshield instead of using tape. Speaking of picky, I kept looking at the main wheels and it really started to bug me so I ordered wheels a bit larger at 2.75" and it looks much better. I also ordered the Robart nose strut pieces to see what I can do with that. I still need to finish the radio installation which leads me to a question. Where did you end up putting the receiver and battery? How long were the servo leads you used for the flaps and aileron servos?

OK Dan here goes, the receiver was put on the floor next to the rear cockpit bulkhead,
used a small straw piece to the antenna wire vertically and another to hold the other one
in a horizontal position. I'm using a Futaba radio system. The battery is positioned just
forward of the elevator and rudder servos on the cockpit floor held in place with Velcro.
the leads for the ailerons and flaps are at present just dangling inside of the cockpit with
keepers on the connections, I will tidy this up after the maiden flight and run them down
the side post center cockpit.
For the time being I am sidelined for a couple of weeks, as I blew my left knee out and have
had to have surgery to re-attach the tenons in my knee, surgery was successful and will have
intense physical therapy for the next 2 weeks to get me mobile again. During the therapy
sessions I will be ale to work on my other project, my Byron RV-4 I've had for several years.
Any other questions don't hesitate to ask.

Well my physical therapy has been going great and it looks like I'm almost back
to normal, if you can call it that at my age. Knee catches every now and then, a
reminder that it's going to take a while for the muscles and tendons to get back to
where I can walk without it catching or feeling like I have stretched something.
Test ran the engine on the Tri-Pacer and have the needle set at about the sweet
spot for the maiden flight which will probably take place mid week. Will report on
how it goes later.

Yep, I'm slow at getting this plane done. I am making progress and am not that far away from being done. I have the nosewheel strut in place, have the aileron servo extensions ordered, installed the front bulkhead support rods in a more scale like location and applied a matte black vinyl anti glare panel in front of the dash. The cowl is painted to match using West Wings RC paint and it came out really good. I also ordered better wheel axles and wing hold thumb screws (hope they work). I still need to attach the wing struts, complete the radio installation and then I should be just about set to go. I'll get pictures up when I get a little more progress done.

Still no maiden as of yet, weather not being very co-operative down here, 1st day it is
favorable and I have to take my other half to a doctors appointment, maybe next week
after the big bout of rain moves through from the tropical depression in the Gulf of Mexico
headed our way, looks like they are forecasting 5-7 or 7-10 inches of rain over a 3 day
period from this thing!!!!!!!!!!!!

I never thought this project would take this long to complete but at least I can say I finally finished this assembly/build project. What a pain in the butt this one was. Of course a lot of what took me so long are the custom things I changed in addition to the stripping of the original covering. I'll get some pictures up soon with details or I might make a video and get that posted.

Yep looks like our project's took a total of around 8 years to complete, really ridicules' for an ARF, but flown as received would have
probably meant a short life span. It's been a long journey, could have built one from plans in less time and been flying long time ago
but live and learn. Weather here hasn't been very co-operative this spring and summer with a rainfall total of 57.54" and a hurricane
on top of that for our area here where I live, folks east of me got 21" of rain just from "Hurricane IDA" on top of the 50+ inches our area
as a whole got so far this year. But have no fear Sunday looks to be an ideal day for the maiden, cool, low winds, party cloudy. If all
goes well it will happen this weekend.

How did your balance work out? Manual says 65 - 70mm from front of wing. Mine works out to be about 70mm. Did your tail bracing change your balance point?

I haven't taken pictures yet, but tonight I was able to finally start and run the OS FS52 engine on this plane. This is the first time in many, many years that this engine has run . I was really surprised that it started on the first application of the starter. I let it run rich until the tank was empty. Before I run it again I'll get some fresh fuel, new glow plug and then I can tweak the high speed and low speed settings to get it ready to fly. I really should invest in a go pro camera .

Test flight is just around the corner.

Took the Tri-Pacer down from the ceiling where it has been hanging out since I finished it, put it on the balancer
and it is neutral with no weight in the nose, will be adding just a tad of weight as I prefer a model just a tad nose
down when on the balancer rather than like it is at present. However got a break from my daily duty I wrote to
you about in a PM, so I took it out to the field to just get away from the house for a few hours and ran a couple
of tanks of fuel through the engine to break it in. Didn't want to chance a maiden as I didn't get a chance to charge
the batteries in either the transmitter or in the plane, I didn't want to risk a failure due to a low battery, so now with
the engine running and transitioning from Idle to full throttle without any hesitation, I am ready for the maiden which
will hopefully take place in about another week and a half all going well.

Good luck on your maiden whenever that shall happen.

We did similar things with the Tri Pacer today . I took mine out to the backyard and got it running well. I have a bad rudder servo so I'm switching that out tonight. On the balance of this plane, I came out at 70mm and it was just about level. I added 2.25 oz of lead to the front of the plane and it hangs just slightly nose down.
So close..........

Will get mine up on the balancer again sometime today and if my calculations are right 2.25 or 2.5 oz.
of weight is going to be just right, going to attach it to the engine mount forward bolt opposite the cylinder
head. Will post some more pics when I can get back in the shop later today.

I had to go into work today and was there longer than what I thought I would be so there's always Monday. If nothing else comes up I'll be good to go and get the flight in. I thought I'd put up a few pictures of what I have done with this plane to get to this point.



Threaded stud glued into the wing. The red nut is really easy to tighten on that stud inside the fuselage. Space gets a little cramped and it's best to install the wings if the seat is removed. With this setup I don't use the screw they show to install into the aluminum joiner tube. I did not glue the tube in place either. Both wings are done the same way.

The flap and aleron servo wires and extension should stay out of the way here.

Tried to hide the wires going to the flaps and aileron with some door edge trim. Bottom left is where I found the best place to mount the receiver.

Gas tank with the receiver battery in place. Best place I could put it because the plane needed a little nose weight.

Needed a little more nose weight. Total mount added was right at 2.25 oz. One weight on top of the engine mount............

One weight on top of the nose gear block and one weight on the bottom of the block. These weights are used for pine car racing and each strip weighs 1 oz. I cut them down for best size fitment which resulted in each of them weighing about .75 oz each.

The Robart nose strut modification. I didn't make a fender for it yet because I'm tired of working on the Tri Pacer!

Here's a few more pictures. Picture quality isn't the best.......it's an old phone .


It's finished..........

Tail shot......

Top of wing. Sure wish I had a better phone or camera.

Still not happy with the engine cut out but I'll be okay with it.

I didn't glue the windshield in. Used #1 black screws and washers.

I made my own on/off switch. Didn't want to keep removing and installing the front windshield to turn it on/off and to check the battery.

My rebuilt door with handle. Used 2-56 wire with threaded end and soldered washer. Lock nut and washer inside to keep it in place.

Sorry about the fuzzy photo.....

The gear fairings are painted and reinforced with balsa. Double sided tape help hold the fairings to the metal landing gear in addition to the nylon bolts and nuts.

Ugggghh. Washed out by the light. I always put a little white on the leading edge.

Fuel filler dot.

Went back and checked the balance with my plate that I made holding 2 oz of weight, plane was neutral,
added another 1 oz and it went nose down a tad , added another 1 oz and plane was typically like I like
them for a maiden see pic 3 & 4

Bracket with 2 oz of lead @ 70 m/m


With 3 oz lead @ 70 m/m

With 4 oz of lead @ 70 m/m

Here's a milestone for today.......I finally flew the Tri Pacer !!!!!!! I'm sorry I don't have a flight video, it was just me at the field today. I made these 2 quick videos after I had just completed the Tri Pacer flight.
