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

[Reeper38]

Loaded and ready for the morning..gopro is charging...im going to fly a bunch of stuff in the morning to get warmed up but by the end of the day I'll have some vid up on youtube...

[Aros]

In honor of your maidens I switched out the header image to the A-10. (Shift+Refresh on your browser on PC). Kick the tires and light the fires!

[Dan McKeag]

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.

[Dan McKeag]

My A10 weighs 30 pounds 4 ounces. I am going to add cloth and resin to the nacelle mounts tonight and be ready for the weekend. I checked CG with gear down and my batteries have to be all the way forward to balance. I can see that abrupt full throttle on takeoff or otherwise would be disastrous. I flipped my FMS A10 over on its lid when I first got that a year ago because I pinned the throttle on takeoff before it had enough speed to liftoff. But I am looking forward to the flight. There is nothing like flying something that makes your knees shake from nervousness.

Hope you’ve both got video camera's ready and charged!
Dan, your JPhobby fans are very similar in weight to the ejets jetfan, around 700g each.
CG with landing gear down.
Don’t go ballistic with full throttle all the time once you’re off the ground, and keep some power on for landing, although you probably know that anyway!
Good luck chaps, chocks away!

[jinkrat4791]

Good luck to both of you!!!! Nice looking jet Reaper, 32.5 is a good auw considering all your mods. Hope you guys have recruited good camera men. Anxiously awaiting the results. And Dan, in the RC groups thread another modeler that had some success with this airframe had to add carbon fiber cloth to the area where the nacelles mount. Ii believe reaper has already done so and im planning the same

[Aros]

Godspeed gents, may they both come down happy and healthy after their maiden voyages. We're rootin' for ya!

[Dan McKeag]

That’s a nice looking jet. I think my JPHobby fans must be heavy.

[Reeper38]

I'll be taking mine up Sunday I put all 4 6s 5000 in the tray and 2 2s 4000 in the nose and came in at .25 nose heavy so ill call it good with auw being 32.5lbs

[Dan McKeag]

This weekend will be the maiden if the weather cooperates. I am running four 5000 mah Spektrum batteries and in order to get the cg at 3 3/4 inches the batteries all had to go right over the front wheel. Tomorrow I will weigh it and report back what that is. I taxi tested it up and down the street and it definitely has the power to take off. You can see the nacelles torque roll to the left if you hit the throttle too fast. I can see during flight that gradual throttle increases will be a good idea. If it survives the maiden I will do a repaint in the correct Alaskan scheme and apply new decals from Callie.

The latex paint i had mixed at the paint store matched very well. I took the outer wing panel and they scanned it. It would be fine for touch ups because you don't have to worry about it being fuel proof. You can even thin it 60/40 with clear windex and spray it with an airbrush

[MWDK9]

Thanks all , I guess I'll have to repaint more close to realistic

[jinkrat4791]

BTW, I don't think there is an actual paint number because the first kit i received had damage and had to be replaced. I received the new airframe before I sent the old one back to RCaerodine and the two were slightly different shades of grey.

[jinkrat4791]

Does any one know what color grey the grey a10 so I can do some scratch touch ups and have it match. I know it's grey but has anyone found a grey that's exact or close to...that matches?

Thanks

I couldn't match it with off the shelf paint, I had my local paint store scan it and match it in a latex house paint to do touch ups and it matched very well but I'm doing a full re-paint with scale colors seeing I've had to remove the wing skin to reinforce the structure

[Dan McKeag]

I could not find anything that was an exact match. Ended up mixing my own and blended it in with the airbrush.

Pullin' for you guys! Much success!

[Reeper38]

I dont know but I'm feeling confident with Dan's reinforcements..looks good should be strong as hell ..im racing ya to be the first to maiden..I should have my fans any day and will throw them in and be ready...good luck to all hopefully with all this shared experience and past failures we have this one cracked...im anxious to get this thing on the xicoy and see how much weight I added in carbon and resin .I know one thing this is probably the stiffest roban a-10 ever I carbon clothed the whole fuse damn near ...good luck everyone and let's hope round 2 goes in my favor ..I really want to show it off at first in flight next month...

[jinkrat4791]

Sky and jink I'm only waiting on the fans to come in stock at efflux..unless someone has another idea ..I don't want to change my escs and the jetfans with the hets only draw 96amp at wot with 18lbs of thrust each ..I have castle 120hvs and can't seem to find another setup comp.to the jetfan pros

Reaper, I just checked the fanjets usa website and they say jetfan 120 pro's in stocks. I've dealt with Matt there and he's great to do business with

[jinkrat4791]

They are an all metal fan. This A10 will be heavy just need to be careful not to slow it down too much on landing.

The ones that actually fly on YouTube and don't explode into confetti seem to land fairly docile. The vid of the green camo one that lands on what looks to be a city street with lamp posts down one side is someone I met in the RCgroups forum named TJ. He has it slowed down to what I'd call a crawl compared to smaller heavy nitro jets I've flown in the past. His came in at 32lbs auw with Shubeler fans. I have a friend thats an A&P mechanic at the small local airport and I have permission to do my initial flights on the main runway so I plan to keep the speed up until I learn the stall characteristics at a safe altitude but I'm hoping that the big wing will allow it to slow down enough for me to fly it at the farm. Otherwise ill have built an airplane that ill have to take out of town to fly
