Default Rebuild of my 80" Marston Pterosaur


About 5 years ago I heard about this guy named Ron Marston who had a most unusual RC company that sold RC pterosaurs. They came in about 5 sizes from an indoor flat foamie to a giant scale 80" model. I built one of the park flyers which barely flew and was nothing but trouble. I blame myself as I really didn't know what I was doing. A couple of years ago I was perusing the RCU want ads and there was an 80" pterosaur for sale. I made a deal with the owner and had it shipped to my house. The seller had told me a friend had built the plane for him and it had never flown. I checked everything over and found that all of the electronics were worthless so I ordered motors, props, esc's, batteries, wiring, receivers, covering, and went to work. Photo (1) I found on the internet and it's of one of the later pterosaurs; Nobu Tamura. I thought the model kind of resembled her. Photo's # 2 & 3 is what showed up at my doorstep. The body was in good shape but the v-tail controls wouldn't move and had to be redone. However, the wing was in bad shape. The hinging on the ailerons and flaps had to be re-done, there were no wires for the controls or for the propultion system, the servos were of a type that would not work in this model, the motors and esc's were for EDF planes, and the whole wing was covered with something like carpenter glue. I had to sand all of that goo of the wing, fix numerous cracks in the wing sheeting, re-hinge all the controls, install proper motors and esc's, run all the wires, cover the beast, and finally balance her. Photo's 5,6,7, & 8 show the fruits of my labors. She was covered in Eagle Green transparent on the top with yellow and red on the bottom. She sports invasion stripes as she is the worlds first warbird from the Pangaean Air Force. Callie Graphics made the custom graphics and the beast was named "Terry Dactall, The Worlds First Warbird". Photo's 9 thru 16 show "Terry" (she lets her friends call her by her first name) being hand launched by Alex Lomov, banking, cruising, approaching, and doing a flyby at Warbirds Over Delaware in 2013. Being allowed to open the noontime show verified her existence as a true warbird and she has been thrilling crowds ever since. However, as Terry lands on her belly and there's been quite a learning curve while mastering the beast, she has gotten beat up. So, I decided to do a rebuild which will consist of repairing any broken structures, recovering with fabric this time, and possibly installing retracts and skis to act as landing gear. So, here we go!

Photo's 1-4 show Terry after all her covering and head fin have been removed. Removing Monokote sucks as you're constantly burning yourself with the heat gun but it had to come off! There was very little damage to the aft of the body but something had to be done about the head and shoulders and I don't mean shampooing! During the learning curve, the head and neck were broken off the body on a regular basis and just glued right back on. When I saw the mess being poorly hidden by the covering, I replaced the sheeting on the head and neck, applied balsa filler, and gave her a good sanding from beak to tail feathers. BTW, that neck was lenghtened to help attain the proper CG. Photos 7 & 8 show the body all repaired and waiting for her wing to be done. However, photos 9 and 10 show the wing after the covering has been stripped. There's cracked sheeting and I'll have to figure out where I can install the retracts. The body holds the receiver, two MG micro servos, and the 3S lipo. This beast is v-tail controlled and is set up like a delta. The wing houses the motors, esc's, 4 servos, and all that wiring! In other words: EVERYTHING ELSE. And let me tell you brother, there's not alot of room. The next couple of days will be spent cooking my fingers with the heat gun, repairing and replacing broken balsa, and sanding forever. Tune in next time to Jurassic Park, RC Style!

That is very cool! I have a friend who loves unusual airplanes. He has a foam Chicken that he flies, this would be right up his alley!

I know someone who has the foam chicken. It's wild!

Greetings from the land that snow forgot. We were supposed to get a blizzard but only got a dusting. The TV weather people flooded the airwaves yesterday and were dead wrong. Today they're tight lipped and very embarrassed. On to the build.

Photos 1 and two show where I ripped the covering off by hand. About half of it stayed on the wing. Photos 3 and 4 show where the excess was taken off with a heat gun and an Xacto knife. Top and bottom was also sanded after this step. What's that you say; you can still see covering and colorant? That's true but in photo 5 I ironed Solartex right on top of the film and it does not bleed through. Solartex is so easy to work with as it goes on and comes off easy and with the opaque stuff you can hide a multitude of sins. Which brings us to photo 6 of the ailerons and flaps (yes this thing has and needs those flaps for landing) which were stripped with the heat gun and knife, sanded, and are ready for covering. Tune in next time when I run my mouth some more.

I used to live in Mechanicsburg, just west of Harrisburg. My parents and in-laws were glad that they didn't get much snow. When we lived in Oklahoma, and the weather forecasters would be forecasting tornadoes we used to say they were having a weather woody.

When they predict snow, they call Philly The City of French Toast. Everyone stocks up on bread, eggs, milk, pancake syrup, and toilet paper. The list used to include Marlboros but not these days.

Howdy builders! Photo 1 shows the top of the wing ready for covering. I ended up replacing the sheeting on the leading edge as by the time I got done sanding, it was paper thin. Also, Terry has new motors which more than doubles her thrust. This should make those hand launches a little less nerve racking. Photo 2 is of the bottom of the wing where you can see the wing tips are orange and the bottom is yellow. This is for visibility. You need all the color you can get on this bird if you want to retain perspective. The top will be orange with white wing tips. The new esc's are installed but you can't see them as they're covered. The servos and horns have been painted yellow so they'll blend in with the wing bottom. When it's all done, the props will be added. She's moving up from 11-7's to 13-6.5's to make use of the new motors. The prop on the right wing is a pusher running clockwise which negates all thrust issues. I figure I've got about three days of work left to cover the wing top, install the new graphics and props, and iron out whatever problems I may encounter. Then, she'll be ready to enter into the WRAM Show Static Judging Contest. Yay!

Hey, It's Feb 4, 2015 and the rebirth of Terry Dactall is here. Photo #1 show what Terry looked like in 2013 at Warbirds Over Delaware. She looked good, flew great, and impressed the crowds but suffered some damage over the last two years. We made her stronger, faster, and more colorful without spending 6 million dollars. Photo #2 is of a cheap bomb you can get from Hobby King with the release mechanism for about $10. Why am I showing this? Look at photos #3 thru 7 and you'll notice Terry has cowls and a little bit of nacelles. These were made by cutting the bombs apart, trimming them, and shaping them into cowls and nacelles. They were then painted flat black and now Terry looks just a little bit more finished. As always, the graphics came from Callie Graphics. Another great job, Callie! Thanks! That's it and we'll see how we do at the static contest as the WRAM Show. Tune in next time when I mess up something else. Bye!

It's official. Terry took 2nd place in the sport category at the WRAM Show. Yay me!
