I said I'd post pics of my outer panel attachment mod so here they are. If I had known I was going to have to open up the wing I may have done it differently. Since I have to open the center section and outer panels I've decided to do a double wing tube because of the weight and size of the model. Im going to use one of the 20mm tubes im adding to the center section as a sleeve for a second wing tube. Ilm going to add ribs to the outer panels to attach the additional wing tube. Iv already ordered the tubes so ill post new pics of the additional mods when completed

So im just curious, am I the only one trying to keep the 3 piece wing? Reaper, I know you said you are going one piece again. Skytrak, what are your plans. I've told you guys that we lost our field and our club fell apart. Most of the time when I fly im by myself. Its just more practical for me to be able to sit the plane down on its gear and attach the outer panels. I've moved this monster around with the wing attached and I don't like the idea of having to flip this thing over by myself every time I fly it.

I notice you've got carbon tubes in the outer section, I like the mod with screw in wheel well, but will it crush and weaken the carbon? I'm using the aluminium tubes, might glue a carbon one inside those for added strength

What are yall doing for brakes? I'm gunna try and adapt the jp 95mm ones ..I shimed my main about 3/16 to help with the difference so itll keep the same aoa. Im still waiting on the package and haven't seen what needs to be done...I know the pin is 8mm so ill have to drill...has anyone else tried? The only other option is intercaro or something like that I think they are called but couldn't find the 4" in stock anywhere...I already took the struts to the machine shop once to be milled so I figured I can find a way to make em work...any advice...if your not flying in grass you definitely need breaks ..that thing will move for days...

Hi Reeper- Xicoy makes a 100mm main wheel with brake that should be decent scale for your Roban. I used the 90mm version on my CGRC A-10 - a little small for true 1/9th but close enough and better than off roading every landing. . The axles are 6mm but you might consider having a local shop make a custom stepped or tapered axle, as opposed to drilling the bearing out. Just a thought.
Cheers.

When we first did the prototype model, we tested different motors and finally ended up using the Scorpion HK4035-560KV motor with 8mm shaft. We had asked Scorpion to have this particular motor done basically for the Roban A-10. I believe they are no longer available. However, I have to make my recommendations to replace your factory plastic provided EDF units. The photos above in camo scheme was well made including all the mods I could think about. CG was spot on and weighted 31 lbs. The aircraft took off successfully. Upon reaching 100 feet,these powerful motor's fan blades shattered and motors popped out on both sides of the engine nacelle.
I suggest using the Shubeller composite 120mm Fan casing. Since the Scorpion motor with 8mm shaft is no longer available, I am using the HET 560 motor for this one final build I am doing. You may call EffluxRC and let them build the EDF unit that includes precision fan blade balancing if you decide to go thatroute. . It'll cost an extra thousand but it'll be worth it.

So I have a question. If the prototype was flyable what happened to quality control during production. I was sold a V1 by RC Aerodyne and blatantly lied to saying it was a V2. V1 V2, I doesn't really matter. We were all sold airframes that fall apart mid air on the first flights. Whoever is responsible for the release of this model owes us all something for the extra man hours and materials we had to come out of pocket for. And im not trying to be the Grinch on Christmas but facts are fact.

Jinx i already recieved the jp 95mm they are so close in size they will be fine.when I tried to order from xicoy my debit card wouldn't work over seas so I said screw it and ordered jps ..they will be fine im taking the axels to a local machine shop and having new ones made that will be longer and step down from 8mm to 6 and mill the hole in the struts..and jp also sells the springs for the struts in the right sizes so I ordered a bunch of different sets of stiffnesses to see what works best..
