Default RE: Top Flite B-25 ARF

Some more progress to report- the things that I've done differently than what the instructions recommend, mostly.

First, something that can bite. The aft fin 4-40 screw can hit the rearmost servo mount screw and break the mount off if it's not shorten to about 1/2" or less.

I like all my airplanes to have access to the fuel line behind the needle valve so I can "pinch" test during initial run up. This is especially critical for a twin, I believe, so I cut a hole in the cowl so I can get in there with a pair of needle nose pliers for pinching, and to remove the line for fueling/defueling. My tank is a three hose Great Planes, the hose shown hanging out the bottom of the cowl is the uppermost (vent), and I've used the secondary fitting on the tank for the exhaust pressure hose. During fueling I'll remove the plug from the vent line so I can see the fuel running out when it's full. When I'm defueling, I'll turn the bird upside down so I can use the vent line, as it is a better way to get all the fuel out of the tank.

I used the fixed gear, and used button head screws to secure the factory doors in place. They look real nice and fit real good.

I went with twin receivers, twin switches and twin 2000 mAh batteries. Having two receivers gives lots more places to hook stuff up without using Y cables. I used them only to connect the inboard flap servos together (to channel 5 on Rx #1), outboard flap servos together (to channel 5 on Rx #2), and rudder servos together (channel 4 on one Rx, while the nose steer servo is channel 4 on the other.) I went with separate channels (1 & 6) on the aileron servos so as to be able to have some differential, with a lot more "up" aileron than down. The 2.4 gig receivers require that the antennas be routed at 90 degrees to each other. All the little pieces of yellow plastic tubing accomplish this- they are glued to the cockpit floor and the antennas are slid into them.

The nose gear steering I made pull-pull rod, instead of cable, because I have an awful time with cable.

This thing fills up the back of a Chevy Traverse. Got the airplane kit in June. Got the Traverse a month ago. That was close
