My buddy built one of these, and LOVES it!

He's running a pull-pull on the rudder (1/4 scale servo, but possibly overkill) and an OS 1.20 Surpass III which he thinks is overkill! To help balance it out, he's put teh battery in the tail. He also splurged for teh fibreglass cowl.

What he would change:

Go wityh a 90 2 stroke. Plenty power.

When sheeting the wings, use 3/32" sheeting instead (the ribs are far apart, so, after sanding, you tend to put fingres through it.

Change the tail wheel with a Klett or something as such.

Change the main axles for the proper 'Du Bro' axles. The screw threads seems to chew the wheel hubs.

Don't bother with the wheel pants, as they always fall off / break/ twist /etc..
