Guys, I was anxious to see what the true weight of the R90 would be after installing my gear. My R90 came in at 18.2 without the prop (still waiting for it to arrive). For your reference here's how my R90 is equipped to give you an idea of how the weight was achieved.
*DLE 55RA with stock muffler
*Hitec HV servos on all surfaces
*Metal servo arms (except on throttle)
*Hobbico 3200 MAH LIFE Battery
*Vess Balance Ring
*Stock fuel tank
*Spot on Battery, Ignition and Receiver trays
*Spot on Wing Bolts
*Aeroworks Metal control arms and titanium pushrods
Also, with my battery at the suggested location, the plane balanced at the recommended CG with just a hint towards being nose heavy which should be perfect. As for the spinner to cowl gap, Ihave about 1/8' gap between the spinner and cowlusing the DLE 55RA stock stand-offs. I have pics of the scale and spinner gap. However, for some reason RCU is not allowing my uploads. I will try to get the pics up later.
