Cox Engine of The Month
Southridge CNC Hyper Viper

Southridge CNC Hyper Viper
I bought one of these kits shortly after they were announced, but just recently got a "round-tuit".
It's done now, so I thought I would share some impressions of the kit and pics. Don't have any in-progress pics, as I didn't plan far enough ahead to take any.
The most unusual feature of the kit is the CNC carved fuselage, which comes in a top & bottom half that just need a final sanding and glued together. Mine was cut from some very nice, light wood. The ribs, and all other shaped parts are also machine cut. The ribs each have two 1/4" square holes that the spars slide into, and function as a wing jig. This was the only area that gave me trouble. The spars were a tight fit in the holes, and fumble-fingered me managed to split 4 of the ribs trying to slide them on. After that, it went together smoothly.
I made the gear removable, since I fly over grass. I also cut the cowl into a front and rear part. The front comes off for engine access. The rear part is glued on over the tank. The tank can still be removed by sliding it out to the front. This strengthens the front of the fuse, which IMO, has a weak point at the rear of the tank bay.
I installed the Tee Dee that Fredvon4 sent me, and a homemade 3/4 oz.tank. Covered it with monokote, in a scheme similar to the Cox one, but with better colors.It actually came out lighter than expected, at 8.7 oz. ready to fly.

Re: Southridge CNC Hyper Viper
Looks the business, how well did it balance out? The proportions are that of the original so I was wondering. The TD being light might make up the difference.
What does the homemade tank look like?

Really nice work with that Monokote. That's a tough one to do, let alone do well and it looks excellent.

You did a great job on the plane. As others stated, also a great job on the covering as well. Looks like it is ready to take to the skies!

Re: Southridge CNC Hyper Viper
I wish I had the patience to produce a finish like this one, I hope it flies as well as it looks.

Duane,
Did you ever fly this one? I'm itching to try one, and have already emailed Gary.

Jim;
I have to admit, this one is still hanging in the shop unflown.
Can't believe it's been almost 2 years.

Shameful….. I don’t have any un-maidened aircraft in my shop whatsoever
When you do fly, keep us in mind I would like to see/hear about it.

Rusty had one and it was close to being complete. I wonder if his buddy Wayne Robinson ever received it.

Re: Southridge CNC Hyper Viper
Ken,
I was going to ask about when his things were being passed around. It was a gift from the forum. We all chipped in and I ordered it and had it shipped to his house. I didn’t want to bother his wife about it. I imagine Wayne has it. I can ask him if you are curious. I did receive some of my items that I gifted him over the years.
