Default RE: U Can Do 3D

HI Guys,
Got a bit late into this thread so I dont know whats been said...Anyway here are my thoughts on the UCD 60.

Building: Dump all the hardware and upgrade it for 3 mm (thats 4-40 FOR ALL OUR AMERICAN FRIENDS :-) ). I mounted the motor sideways (OS91FX 2st), as the tank looks way too high to run a 2st inverted, mounting it sideways brings it about 1/4" below the needle valve on the OS which is OK.

I run 3305 futaba servos on rudder and 3010 every where else..all @ 4.8v

The plane balanced perfectly (5" from LE) with the battery above the fuel tank and the extra weight of the upgraded HW.

Flying:

I have about 4 deg right thrust on the motor and it still needs a little right aileron to hover, but makes torque rolls easier!

I flew this thing last wekend and WOW, makes you look like a real expert. Hovers almost hands off, Elevators are alot easier inverted, Blenders are OK but not as flat as I'd like, but I've only flown this thing 4 times! cant wait for this weekend. I'd guess at this stage I feel its not as capable as my funtana; but still GREAT FUN!!!

One final note on the engine...the os 91fx (I'm at about 200 ft above sea level here) hovers at about 2/3 throttle with 10% nitro on 15 x 6 APC..which is ok, but doesnt really give you a quick getaway when you get in trouble. I would suggest a saito 1.20 or OS 1.08 may be better choices......I have a moki 1.35 doing nothing at the moment.....but that would be a bit too much weight I reckon..

Anyway if you reading this thread and are still unsure if you want to buy a UCD.....its a bit of a no brainer....BUY ONE! A genuine rc bargain...

PS: for those UK chaps, buy some imperial allen keys as the kit hasnt been Europeanised yet!!
