Spacemanspiff's EDF-64 Fan trainer


I just finished the Beanie Fan trainer with a couple of mods. The first one was the wing span simply added an inch to each tip. Second was the cowl/cockpit where I used the plan for the cowl and added the plexi formed cockpit cover. Thirdly, I figured there would be a lot of turbulence where the EDF blew back on the X of the fuse so I removed the X and added a depron tube from the EDF to the tail. I dont think adding the front intakes (see pic) do anything but add appearance.

I have installed a 1320 3s lipo and a GW/EDF55-300H, two micro servos (Ailerons and stabilizer) connected to a Pixie-20P ESC and an R4P II receiver.

The plane is 25 w/s 26 Fuse and weighs 9.9 oz loaded. Its too damn cold and wet here to go flying yet so cant share those results yet.

It is a very simple build, only 7 pcs in the original plan. My ducting added a couple more. For anyone starting out and interested in EDF, I think this may be a winner. I used gorilla glue for all of it and smacked on a quick coat of Flecto Colors in Plastic Red. This is a mineral spirit based paint but it did not attack the foam at all

I think the main fuse body has bulky looking. Lines but that can easily be changed on another build. The T-Tail seems a bit flexy to me and possibly I should have added a stiffener, but well see. I didnt have any carbon fiber rods on hand so I used a couple of bamboo skewers in the wing and tail. The wing might not be as stiff as carbon rod but I have no experience with carbon rod so Im not certain what the diff would be.

My hat is off to all of you involved with the WattFlyer Forums. I havent had so much fun since I was a boy (about 55 yrs ago). My wife even thinks its good for me to find a hobby that helps me to unwind. (Boy do I have her trained!!) Depron is a blast to work with, its inexpensive, easy to cut, glue and finish. What a gas Im havin ! Thanks to all of you out there who are willing to share your invaluable experience so unselfishly.

hey john, that looks awesome. i like the mods you made to the plans. how does she fly? i think i'll add some wing like you did to a future fantrainer. i've had to keep the speed up to keep her from dropping out of the sky. any possibility of posting plans for the mods of my plans?

Hey there Beanie,
Welcome to WattFlyer.com.
The mods I did to the FanTrainer were really very simple. I first built the plane from the plan, then decided to just remove most of the "X" structure from the EDF back. I rolled a piece of Depron 2mm to form the exhaust tube, then re-attached what was left of the "X" structure to the outside of the tube. It didn't look right to me so I formed another tube,Depron 2mm, then cut it into four pieces lengthwise. These I formed to fit to the fuselage. On the next one I will make this tube full length right from the get go. The canopy was made from light plexi vacume formed over a plug I made from a piece of spruce. The rest is really as per the plans.
I haven't flown it yet cause the winds have been gusting up to 30 mph. and its been really wet here. This thing went together so fast that I didn't take any pictures as I progressed. It really is a simple build.
John

G'day John,
Great mod, looks great. Did you get a maiden? and does the extra inch on the wing help?
Where did you get the Wattflyer logo from.
I have tryed to modify one to put on some of my aircraft but my computer drawing skill suck...

Hi Pez,
I took the WattFlyer logo from this site into my computor and just printed it. I think I actually put it into Corell Draw and made it a bit smaller. Then I just cut it out with the exacto knife and taped it to the wing. Then applied paint with a short bristled brush (sort of stenciled it on). It did take a few minutes to cut it all out, but I can use the paper stencil over and over for quite a while.
Haven't flown it yet cause it's just too cold here for me yet. Will report once I've had a chance to fly it.
John
