My original intention was to use my Saito .30 in it, and around 9 oz this was looking to be a real strech. So my next move was to loosely assemble it and try to get a rough idea of what it would take to balance it. I got everything in place, the Saito and cowl taped as closely into position as possible... -wow! Not looking too good, so I swapped the Saito .30 for an as yet untried (NIB) AP Hornet .09. Hmmm, still looks like it's going to be a challenge so I took another tack and removed the existing motor mount. This was scary-easy, just a little wiggling here and there and things started to crack loose. In under 5 minutes I had the mount removed and also the floor of the fuselage.

I have since used my heat gun and iron to attack the wrinkles. I'm pretty finicky about wrinkles... Couldn't get them out as well as I wanted.
