New TD .010 and Pee Wee .020 Planes

Post  Tee Bee on Fri Jul 14, 2017 3:01 am

I've been restoring/repairing a lot of old Cox engines lately which has made me daydream about planes that would be a good match for whichever engine I was working on at the time. As I tinkered with refurbishing a couple of TD .010s, I realized that I didn't currently have an airworthy .010 plane. I also have a couple of Pee Wees that will be finished soon and I've never had a Pee Wee powered plane. I used to fly my LaStick with a TD .010 years ago when I built it. It was fun but performance was lackluster as my flying skills improved. I converted it to a TD .020 and have had a ball flying it lik
e that for years since. So, I started with the LaStick design and shrunk it to 75%. Reshaped the tail and eliminated the triangular wingtips to make it look a little less Stickish. Span will be about 15". Looks like they will be small and spritely to fly. Do you guys think the airfoil will work ok shrunk down like this without reshaping it? I once shrunk a model plan by 50%. The original was a super friendly docile flyer. The half-size version was very hot and would stall or snap at the drop of a hat if it was maneuvered abrubtly or slowed a bit too much in a turn. A completely different airplane than it's full size counterpart.

Thanks, Mauricio! I always enjoy watching your model vids on the tube. I already have a couple of projects in the works for a TD .020 and reedie .049. Stay tuned for those. These little guys are "extra" projects I'll be working on during the breaks. Smile Actually, I'm leaving town on a motorcycle trip, so the model building and Cox engine work should resume in a few weeks.

Thanks! I like to share the videos for just that other people can also appreciate the result and performance of these small engines, ie very small displacement. They are a little jewel
..... from here I wish you a happy trip !, surely in this same post we can see some photos of some parts of the tour! ... a hug!

It would appear that the upcoming S.M.A.L.L. Fly-In (I know: it's next year, but I like the   term) is gonna have a lot of hot little Bees blasting around the place....

P.S. Edit: Please take care on the bike !

I always thought a good rule of thumb was the wing chord should be 1/4 to 1/3 the length of the plane frame. It looks a little short to me.

Thanks! I hope Evelyn is having a good summer. Angie's not going on this trip. Since she got asthma a few years back, she doesn't do well at high elevations. Ended up in the hospital last time we camped up there with very low O2 in her blood and dehydrated. I had to take her down to 5000ft to get her better. Since then, she's been diagnosed and has meds for it but she's working to build up her lung capacity with more exercise before trying the mountains again. I'm traveling with my friend, Rob, whom I used to work with. He rode with me last year to NM and CO and had a blast so decided to come along on another adventure. I have a much bigger and more challenging ride planned in 2 years, and he's feeling it out to see if that sort of thing is for him before committing. I should be back to work making balsa dust in a couple of weeks.

Good luck on the road-trip Troy. I enjoyed reading your recent posts on the prep, in Bob's motorcycle thread. Also.. great job on the testing of the new NVA/venturi from EXmodel Engines! I'll be curious to see the progression of this airplane when you return.
