Title: Frank's RV 4 30CC RV 4 by Horizon Hobbies
Post by: Frank v B on February 10, 2019, 09:45:41 pm
A re-start on this build.

Waited for the new motor mount.  The problem was the plane was designed for a Power 180 but the customer wanted a Power 360 (50CC equivalent).  The new motor mount is a 60 CC size for their XCUB 60CC.  Have to try to retrofit the firewall to accept this motor.

The new motor- Power 360 weighs 2.75 pounds, 6000 watts, can draw a continuous 130 Amps and needs a 160 amp ESC.

This plane should have unlimited vertical at idle!!

The reason for the green tape- To protect the motor from random metal pieces being sucked into the magnets.  Don't under-estimate this problem.  When building the SuperSportster the motor developed a rough spot.  It turned out a tiny piece of piano wire had attached itself to the magnets inside the motor.  Had to carefully remove it with surgical clamps.  Now the motor spins perfectly.  I then immediately taped up the large motor.

Sorry. Stop. Hang on.

Is that a genuine compliment from Andy to Frank?

Is everything Ok? Has hell frozen?

Simon,

re: "Has hell frozen?"

Apparently.
He must be getting soft in his old age. ;)

Oh my goodness!  What have I done?  Must have been a very weak moment.

I think I will go out and clear some snow to exorcise my Dutch Demons!   8)

So very sorry for upsetting your equanimity!!
