Don't tempt me.

The good thing about the MSR is I could order a pile of replacement parts and it caused no damage to anything else. If I go bigger, it gets more dangerous as well as expensive. The kids and I used to have competitions to land on small elevated platforms anr move small objects.

These days, all the coax stuff has been hacked up to use bricks in other things. I have a 1/1200 Yamato that is double screw steeering via a coax heli brick. I'm finishing up a 1/128 Flying Sub fom Voyage to the Bottom of the Sea that steers via two impellers. The sub is under three inches wide. Coax bricks are great since they have two servos and two FETs that can be controlled by rudder movement.
