Proud Bird EF1 - Build and Review

Postby DonStegall » Sun Jan 28, 2018 9:14 am

This is a fairly short introduction video for the Proud Bird EF1 Pylon Racing plane by Great Planes. I've had a couple sitting unopened in the box for a couple of years. With all the molds I'm making, I decided it was time to get them out and make molds for the plastic pieces that come in the kit. I consulted with my friend Jim Allen who was the designer of the plane about tips on the plastic pieces and on putting the plane together. Jim cut me two vinyl color schemes and they will be applied in this complete build series.

Don,

I'd have posted these comments to the video but you have them turned off.

I've raced the Proud Bird almost exclusively for the past three years. It's a great choice for racing in EF1 if you're not a builder.

Magnets - use wax paper between the magnets and glue the loose ones to the canopy. Kicker helps here. Also each of my Proud Birds has decided to shed it's canopy when I've flown it with just the magnets as the amount of airflow entering the fuselage creates enough positive pressure that it can overcome the magnets and cause it to depart the airplane. I suggest adding a bit of tape to the back of the canopy where it meets the fuselage unless you like searching for your canopy in the weeds and going 15 miles per hour slower than your competition. Having a spare canopy ready to go is also a very good idea if you're planning to race. I've seen other canopy retention solutions as well but tape works and adds very little weight.

Cowl - Sand the wood in the nose to get the cowl as far back as possible. There's lots of variance between kits and cowls and you do NOT want to spacer the motor out more than three or four wood spacers or the CG will be too far forward. If you don't do this you'll find you'll have to add a reasonable amount of lead weight to the tail which results in a heavier than necessary Proud Bird. I know this is contrary to what Jim Allen has told you but trust me, it's necessary to do this on the ARFs.

Right thrust - I don't bother with the washers - I just add a few clicks of right rudder to keep the nose straighter in the turns. Also a gyro/stabilizer on the rudder with a bit of heading hold configured will fix this issue. However I'm not going to dispute what Jim has said, just stating what I do.

ESC - The Castle Creations ESC is great but for a more economical solution the Hobbyking Plush 60A is fine and a bit lighter. You sacrifice the logging capability but you'll lose a bit of weight near the nose.

Motor - you're correct - the Rimfire motor seems to be the best of the ones currently available for EF1 but they can be inconsistent. I have three and they all turn different RPM's on the same airplane with the same ESC/Battery/Prop. Best advice I can offer is that to be competitive you need an EF1 motor which will be turning very high 14K/low 15K at the END of the run. If you turning mid 14K's at the end of the pylon run you're not going to be able to keep up assuming you're flying as tight and smooth a course as your competition.

Battery - I'd recommend the ThunderPower Rampage packs. I've had other batteries which perform a little better but the Rampage packs are LIGHT!

Weight - Proud Birds build light because Jim designed them when 3.25 lbs was the min weight. Today it's 3.5 lbs so it's likely that when the Proud Bird is assembled it'll be underweight. That's not a bad thing as it's also likely it'll need a bit of tail weight to make CG.

Quality of the kit - Mine have been variable over the past few years. The sheeting in the wing seems a little brittle and I've seen some really green balsa when I've recovered the tail pieces. However the wing and fuselage are strong out of the box and will happily take hard pylon turns without flexing like some other EF1 ARFs will (I'm looking at you Scarlet Screamer!).

Anyway, those are my thoughts on the Proud Bird. Thanks for taking the time to create the video.

Thanks. I didn't know comments were turned off.

Was that on the http://RCPylon.TV or http://DonStegall.com channels? Or both?

I will try to turn on the comments if they are configured to be off and will let you know when to try again.

Please post to the video. Very good feedback and info.

I have a good RealFlight EF1 course and an adjusted Proud Bird EF1 with 2 and 3 degrees as well as an AR-6 and Little Toni EF1 planes "built" from scratch. They will soon be posted to http://EF1Pylon.com ... I can email them until I get them online ... Don.F.Stegall@gmail.com

I worked on RCPylon.TV ... I get comments on my personal channel all the time, but I don't know that I've gotten any on RCPylon.TV ...

BTW, I'm going to be making the first set of wing fairing and belly pan molds soon. They will be made right off of the stock parts.

I'm also going to make a hatch mold when I make molds of the fairings fitted and mounted on the fuselage. I've seen a number of people with painted canopies and I like fiberglass parts on any plane over plastic, even if I add a clear copy to the hatch.

I'm going to be making a ton of videos. My office and shops are getting cleaned up, but the video taping station stays the cleanest. I make the videos just to share my experiences. If I can get to 100 subscribers on RCPylon.TV I can get a better YouTube URL, so please subscribe. My personal channel has over 1000 subscribers and I essentially have unlimited YouTube capabilities.

A bit of news ... The World Models now has the Outrageous in solid white and the Scarlet Screamer in the scale red fuselage with white wing, stab, and wheel pants now. Videos to come.

Did TWM also add the sheer webbing necessary to keep the wings from flexing when they changed the covering on the Outrageous and Scarlet Screamer? If not I'd recommend stripping the wing and adding it or you risk wing failure turning around pylon 1.

I watched the video on YouTube. Comments there seemed to be disabled.

I'm not sure if they changed the wing. I wasn't aware that changes were needed and I don't know if the did either. There are a limited number of the new ones in the US. Maybe they don't have a lot in China already built and we can get changes made.

BTW, I plan to bring the Outrageous and Scarlet Screamer back as laser cut kit.

I did some stuff and checked the videoo out using another account. It didn't seem to be working when I tested it after the above message.

Are you using a YouTube account and can you comment on other videos?

Please go to https://www.youtube.com/watch?v=0qqXv4vNwQ4 and see if you can comment now.

I've worked hard to get my video / clean work table area lit properly and set up with the green screen. There are actually three windows right behind where I sit and I put up black shades to keep the outside light from messing up the green screen. Just made a change last night to have more of the same daylight adjusted overhead lighting. I have more bulbs coming for the shop lights like these whoppers.

I've constantly worked to have better production of the videos. My son and his fiancee who was a media major don't like my moving cloud background, but it works better than a still image on the chroma-keying. I actually got that background from my deck. I pointed the GoPro at the sky ang got about 8 minutes of video.

Comments good and bad and Likes and Dislikes are appreciated. If you have not subscribed to http://RCPylon.TV, please do so.

For those that know I've had serious health issues in the past (posted about it on Facebook) and last year especially can probably tell I'm feeling much better now.

I just unboxed a new Scarlet Screamer. Will be unboxing a new Outrageous.

Not only do the wings have sheer webs, they are now fully sheeted. I had asked for this but did not know they implemented it. The wings are very stiff, and the weight is right at the same as the old wing ... 5.0 to 5.6 ounces per panel.

I have 4 solid white Outrageous ARF kits and 4 scale color scheme red and white Scarlet Screamer ARF kits available. They will be listed on the http://StegallHobbies.store on Amazon this week. They are also available direct from us and from http://airborne-models.com/

Nice to know. Did the fuselage change? Wondering if the new wings would fit on the original fuse... :)
