I've been wanting to build one of those. Do you have the plans?

Thanks, Terry

Hi Terry:

I have the origional plans and will see if I can scan them or make copies. They are suitable for an experienced builder. You will need to cut the wing core and make a cowl and landing gear. I will send you a PM with details.

Ha ha! I love it! Looks like fun!

I am sketching up a similar thing but in 1/2A size right now - small, stupid overpowered, light, very maneuverable - and was inspired by the Cox plastic C/L Cub hanging from the workshop ceiling.

Oh btw I am interested in plans for this if they are available somehow.

Hi Tom,

Yes I am very interested in acquiring the plans. Let me know the cost and I will get the money to you. I saw Tony Pacini fly one of these at have wanted one every since.

Blessings, Terry

Hi guys,

Tom was kind enough to send me the plans and manual for this cub. Now I have some questions before I build it. The original one used a Nelson Q500, 40 for power and used the ReVlution airfoil reduced to an 8" cord, 48 " long plus tips, giving it a little over 400 Square inches.

Here are my questions.
I own a couple of engines that I think might work well though I know they won't be quite as fast as the Nelson.

The first is the Jett SJ50 with the gold pipe. To use it I would have to increase the wing area to 475 squares. The easiest way to accomplish this would be to go with a 9" cord and 48" span + tips which should be enough. To use this cub for Gold class, it needs to fly around 140 MPH. Do you think I can get there with this combination?

The other engine I am thinking about is a YS 45 with Ultra thrust muffler. For this I only need 438 squares which I could accomplish with an 8" cord and a 50" span + tips.

Anyway, I'm open for suggestions. There are no rules on how thick the wing needs to be so if you have a suggestion on a faster airfoil than the quickie wings let me know. I have to have the wing core cut anyway.

Also, what are the fastest Q500 airfoils if you know.

Thanks, Terry
