Hi I've just found this forum, and I think is great, I own a u-can-do and these is what i have on it,
O.S. max 0.91 fx
15 x 4 apc prop
3004 BB. futaba servos
2000 mamps 5 cell batery
4-40 rods all surface controls
dubro giant arms for futaba
G.P. filler valve
stock spinner.

What can i say, this plane had rock the field , is my first 3d and the first in the club that had performed 3d like manouvers, well i'm still practicing, and I hope some day i can reach the 3d level experties i desired.
With the 91 fx i've got plenty power to do averithing i want, we are at 1140 mm over sea level (3740 ft over sea level) and the engine works fine. The 3004 servos with a 5 cel bat. are suficient to handle the required torque specs and velocity, this way you avoid the expensive hi torque, digital, coreless, etc. servos. Computer radio is a must, you will need independent surface control for this plane, this will give you flexibility and a bunch of new manouvers.
I have just a couple of complains about this arf, the suplied spinner is not very good, and i had to trim a litle bit of plastic from back plate on the engine side, (just enoght to have the back plate in all the way against the engine plate). Also the tail l.g. pop out it's place on a landing, I'm giong to replace it for a sullivan too.

Ive got 8 sorties with the aircraft and I agree , is one of the best machines I have owned.

To the web page administrators, you do not have all the countries to sellect from when you are regestering, I had to use " New Mexico".
