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

[Reeper38]

Yeah I was being really gentle on my turns and rubbering it around and leveled out and boom ...once i saw what the inside of the center section looked like i knew what was wrong..the shear webbing isn't even close to strong enough for 30lbs ...I spoke with the roban man at motion and he said do a layer of glass on the leading and trailing edges also...and jinx its a matter of time before theres blows apart too if they dont fix it now

[Reeper38]

Its ok i learned and the second one will be an amazing plane..built strong

[Aros]

Here's the video... Man that just sucks! No yank and banking...Just flat out wing support failure on straight and level.

[jinkrat4791]

just watched it, that's crazy, i know a guy who has built and flown two of these V1's stock with no mods at all. he flies it scale like but i didn't see anything you did in that flight that put any real stress on that airframe.

[Reeper38]

Type in roban v1 wing failure and see what happens...the vid is sideways

[jinkrat4791]

ive tried to find the video but i cant, i typed exactly what you said

[jinkrat4791]

i couldn't find the video, if you can post a link to it, but I'll definitely call you this eve

[Reeper38]

Did you watch the vid...go to steven reeps roban a10 on you tube you will see a red bae hawk and the a10 at the begging

[Reeper38]

And no I didn't do the center of the first one I didn't know that was where it was breaking I thought it was where the wings join..

[Reeper38]

I just added carbon instead of the aluminum tubes and fused the wings together yeah just call me later

[jinkrat4791]

The area between the spar sleeves is where it breaks
firing out with 3/16 and then 1/8th to connect all ..then adding a carbon 20mm spar all the way across into wings..and adding 2 ribs also beefing up gear mounts

did u add the carbon tube through the center section like we talked about the first time, what exactly did you do on the center section on the first model, and once again im terribly sorry about your first model, it made me sick for you when i logged on. i was checking in just to see if you had done the maiden yet. if you don't mind i i may give you a call this evening after work, i want to hear all the details

[Reeper38]

Definitely has to be opened 100% i was clean and level ...go on you tube and look at steven reeps roban a10 ...it just folded i was 30 seconds in maybe and she was flying amazing....I already am working on the new spar system

[jinkrat4791]

Reaper, man im so sorry to see that happened. i can't believe you're starting a new one. i didn't see a video, how long did it actually fly before it came apart and were you just in straight and level flight when it came apart or were you seeing if she was yank and bank capable, this has me rethinking my mod but im still inclined to think with the new dpar and foam will hold up. what do you think Reaper? should i try mine as is or does it have to be opened up?

[Skytrakvideo]

Reeper - Did you get new one at discount price?

[Skytrakvideo]

BUT.... modifications to woodwork needed, down and locked fit straight in. I'm in UK so was too costly with shipping for D&L conversion. Not changed springs.

[Skytrakvideo]

ELECTRON Er40 evo set of 3 with controller around £400 or $520, they are better in my opinion than the down and locked conversion, one piece frame and just stronger in every way, the motors drive a square acme thread, not an ordinary screw thread.

[Reeper38]

How much where the evos? I'm probably going to send these to mitch and have them rebuilt...did u change the springs

[Skytrakvideo]

20mm OD 1mm wall, retracts are Electron 40evo, ordered them with 11mm trunnion for front and 12.7mm for mains, original struts fit nicely, front needed woodwork mods but mains needed very little, changed T nuts from 3mm to 4mm and put plenty Hysol glue around internal edges.

[Reeper38]

using? Those 18 or 20mm o.d. tubes
