Official Roban 120mm A-10 Warthog V2 EDF Jet Thread

Have any of you changed out the control horns for something that does not protrude thru the control surface? Carbon fiber or something? If so let me know its something I want to change after the maiden.

I considered using the stock horns but cutting the heads off and just drilling up to, but not through the upper skin and epoxy them in. I think if I'm going to go through that much trouble, cutting new ones out of carbon fiber plate wouldn't be that much more work and it would look much cleaner. Smart move adding the carbon to the nacelle mounting area. Personally I don't think a couple lite ply formers added to that area to help it hold its shape under stress would hurt either. In my opinion the whole airframe is a little on the weak side. I'm taking precautions

Bad maiden super tail heavy xicoy lied or I messed up somewhere...I used my original from the first and that think was perfect...luckily I over buit it and my emergency landing only bent the struts and retracts ..ill fix it after first inflight
video coming soon

Hey buddy, I think you're still ahead of the game considering it held together in the air. When you figure out the CG let us know, that's one thing I've been sweating since day one. Personally I'm not up enough on tech like the Xicoy to trust an expensive airplane too it. Guess I'm just old fashioned. Looking forward to the video, I just want to see another one of these actually complete a flight

So guys, any news on the maidens?

I am still waiting for a saturday with the right weather. Maybe this weekend. We have had lots of wind and rain here in the Black Hills.

[jinkrat4791]

Have a question for anyone who could help answer. I had done a bunch of detail work on my cockpit when I first started on this kit. I want yo make some changes and I don't want to just paint over what I've done. Is there something that I can use to remove the factory paint as well as the Testors acrylics that I added without it attacking the plastic

[Skytrakvideo]

Nail polish remover / acetone and a toothbrush..... test the plastic first, might soften it.... then clean with plenty of water.

[Aros]

I can attest to nail polish remover's effectiveness. One day I made a completely idiotic choice to do a quick gluing of some innocuous part on some model of mine while I had it on our granite counter in the kitchen and because, well, DUH! I ended up getting a nice glop of CA on the granite! I panicked and tried everything I could think of before the wife found out. I was at my wit's end, sweat forming on my forehead when I finally found a website that mentioned nail polish remover. It WORKED! Didn't leave a single trace nor did it hurt the granite at all. Miracle stuff.

[jinkrat4791]

I had already tried the acetone, it worked well on the acrylic paint I added in detailing but the paint that was already on it turned into a sticky goo. It didn't attack the plastic though so with a little elbow grease and a ton of paper towels I eventually got it cleaned. Thanks for the replies.

Any maiden flights yet guys???

[Skytrakvideo]

Any news on your A10's ...... all quiet!
Reeper.... have you abandoned it and gone big with Skymaster?

[rcairmark]

Anyone out there know where I can buy Roban's A-10 Canopy and cockpit set? Or anyone on this thread that has one to sell. Many Thanks.

36 lbs. flying weight. CG was by the book, I left it 1.5 oz. tail heavy ( personal preference ). Battery position: 2 on the bottom tray with 2 on top moved forward 1/2" past 1st set of blind nuts from nosewheel gear. Hope this helps....

Wow, congrats rcairmark on the successful maiden and great landing too! I believe that is the first Roban A-10 flight I've seen on video, at least on this site. Smart for doing those mods or it may not have been a success. Here's to many more! Cheers!

[Skytrakvideo]

Rcairmark, excellent job, great to see one flying at last, nice landing!
Mine has sat half finished for the last year, both Roban A10 threads went quiet,
seems everyone lost interest!

[Skytrakvideo]

Can anyone identify this A10 maker.... Same size as small Skymaster A10 but Skymaster wings different. ..... Slightly larger than Roban...wong splits in same place!
