The video was of the second flight after I repaired it. The first flight I had a 4s 2200 battery and it made it very hard to keep nose up. (Nose heavy big time). As I was bringing it in, I hit the throttle and she dropped on me.
Welcome to WF, charlesrc! That's an excellent build there and video. (RC planes I think are the hardest things in the world to video.) I was wondering until you said it in the video if that was on 3s or 4s. I have a couple of 64mm edf's I run with Zippy Compact 4s 2200 batts. They're barely heavier that 3s 2200's I have somehow, and they've been excellent batteries for me. Many, many flights on them, and I'm pulling ~45 amps at full power. I can fly them on 3s as well, but there's a huge decrease in thrust, so it sounds strange your plane flies better on 3s. I guess it's the weight saving? Depending on your motor, maybe that could help? Also, I see you used a thrust tube, but did you calculate the fan swept area-to-exhaust area ratio? I haven't applied it to anything yet, but I read 80-85% is supposed to be optimum. Might help some for speed.
Thanks for sharing. Hope you do a build thread on the next one.
Edit: you posted again while I was typing. Thanks for sharing the plans!
I'm not that great with EDF's. That was the first plane I built from scratch with a EDF that flew. I played around with the tube and got lucky with it. What sucks is that the house in the video now houses my plane on the top of the trees. Messed up and looked down for the retract switch and lost the site and about time i found it, in the top of the trees. I like the Zippy packs. I used a 3s and it flew awesome. This build will be a pusher with no tracts with flaps and rudders. This time i will cover this one. The pink camo worked to good!!! Ha HA
Don't feel too bad about the run in with a tree. I have had planes ranging from a classic Hobie Hawk glider, a small pusher jet, and a 3D trainer in trees before. The 3D plane took me 5 weeks to find someone who would climb the tree and throw it out.
I have learned that;
1, There is an unknown attractive force between trees and items like RC planes and kites.
2, Trees will jump out and catch RC airplanes
3, Given time, trees will try to camouflage or otherwise hide, airplanes stuck in them.
4, Given enough time trees will eat planes.
I'm sure there are other things I can't remember right now
I'm new to this website and so far It's pretty cool. I built a 34" Bobcat that flew awesome but doesn't look awesome in a tree long story.
I'm going to build another one without retracts this time and make it a pusher. The first one had a 64mm fan and eflite-25 tracts. I will try to post the video and pics i took of the build.
I plan on starting a new build with plans. Also love to get feed back on the build.
Hi Charles and Welcome to Wattflyers Nice Bob Cat one suggestion, make the ailerons longer, all the way to the booms for better control, If your interested, here are a few of my Scratch builds that you can have fun with, Take care and have fun, Chellie
Thank you. your planes is what gave me the idea to build one. I was going to make the ailerons longer but i'm adding flaps to this build but i will change it up on my plans for longer ailerons. Thank you!!!
I grew up near MKE (Elm Grove) and know Manitowoc . Used to be a ship building town and I think there's a Nuke power plant in Two Rivers nearby . A far stretch from San Diego. Brrrr. At least you have a better football team there- Go Packers !
