Well I just about got my RCU Bipe completed... it's rpetty sweet!
I did review of the Turmoil Flatout a while back and really liked it so when the RCU bipe came out... well I had to give it a try!
The elevator and fuse is built first...

Next we put the wings together... some people don't like the hinging system...a nd you do have to read the instructions because it's different... but once you get the tirck to it, they are real nice... you can always mod and use tape hinges...
heck out the cool logo in the center of the wing... http://image.rcuniverse.com/forum/image/s45.gif

The the wings and fuse are mated... Since I am going to go without gear (fly alot off grass) I'll have to come up with some bracing modes...

For the bracing I used some extra CF I had handy and a little bit of 1/4" tristock... I simply put one rod each side going from the bottom of the fuse up to the strut on the top wing.
I just drilled the tristock and glued the rod in place with the tristock. Nice and sturdy...

I went with the entire Electrifly package... I think the RimFire is a good value and powerful for this size aircraft. Instead of the BL-8 which I used before without trouble, I ended up trying the SS-08... some have reported issues wiht a batch of BL-8's and there's no reason not to try the SS... this is the 2nd SS ESC (http://www.rcuniverse.com/buynow/keywordclick.cfm?bid_id=2595) I have and I like them alot... Basic, but very functional and priced right.

Unless you swap out the control horns with DuBro or other design, you are stuck using their clevises... They are nice, and designed to be adjustable... but what I found later is that they are either too tight and therefore nearly impossible to adjust on the plane... or too loose and slip after a few bumps...
My answer? USe the control horn end, but change to ez links on the servo arms... still adjustable, and no hassles.
On the ailerons, I glued two 1/32" aircraft ply rails underneath teh servo bay and screwed my Futaba 3110 servos in place... I just hotmelt glued the tail servos in.

The receiver is the Electrifly 4 channel single conversion... nice priced and small... I'm not worried about range at all because this thing is gonna be within arms length most of the time... (I hope) http://image.rcuniverse.com/forum/image/s45.gif

All I have left to do is attach the pushrods and set my throws... I'll be using the ElectrFly 11.1 volt 640 mah pack good for 15c and an APC 10x3.8 slowflyer prop. This gave good performance on my Turmoil.
A quick weigh in puts me right at at 11 oz even all up... Sounds pretty good for this big bipe... http://image.rcuniverse.com/forum/image/s49.gif

BTW anyone whose getting ready to build this plane should be aware of a tech notice on the manual... the clips are aweful hard to clip on and off the hinges, so they are recommingding trimming them some...
See here the addendum"
Here is a revised manual with all changes:

Well it's completed and maidened! 10.9 oz all up with a 10x4.7 GWS slowflyer prop and ElectriFLy 640mah 11.1 volt pack...
What a ball! I really do like these Rimfire's they are really powerful for the size. Hovers about 1/3 or less throttle and skyrockets at full.
Had a little wind... 4-5 mph... flew pretty well in it...
Hovers and harriers are rock solid... Rudder is very authoritative and pinwheels can be done.
A little roll coupling, but that's ot be expected, but not near as much as other bipes I've flown... very mild.
I look forward to getting more time on it... but it's a keeper for sure. That is til I beat it all to pieces... which I eventually will trying to learn the torque rolls down low...
