GW Extra 260 70" / 3DHS Velox 70" and VVRC 20cc gas engine

Hi,

Need your comments on these airframes (GoldWing Extra 260 70" / 3DHS Velox 70") for a 20cc VVRC (XYZ) gas engine.

Francis

The Velox has really good hardware and a proven performer. While I haven't read much on the GW Extra.
IMO the Extra is a better looking plane, but with my GW's I had lot's of mods such as coating all the plywood with ca and glassing the motor boxes. I also changed the hinges. They started failing not long after flying them..
Either way you go I would love to see a build thread as I've been looking at these planes.

20cc gas on a 70" wingspan plane strikes me as a little small and/or underpowered, as most folk running things like DLE20's when talking aerobats are running them on things around 60" - MAYBE 65" for sport usage.
Perhaps a 26-30cc might be a better option?
I'm going to TRY a 3.15hp CRRC Pro 26cc in my 73" SBACH, as I'll only be using that for sport/mild aerobatic flying (since my heli's hover and flip around just fine, my planes don't need to )

Here's a fine example of a 70" w/dle 20. Seems to be adequate power. I have this setup. Seems to be a good combo, w/o too much weight penalty. Good combo IMHO. Just my opinion though. Other pilots/friends/witnesses say that it's got plenty of power. But the video should help you I'm with Joe on this one. Go velox.

Well, I watched that, and are now VERY happy with my choice of motor for my 73" Sbach (CRRC 26cc - 3.15hp), as I was only wanting to do 'sport aerobatic' with it, I'm pretty sure I won't be lacking power for it's intended use that's for sure!

The Velox in that video is actually powered by a DLE 30 not a 20.
