Build Log
Fundango

I bought this kit 10 maybe 12 years ago my life got super busy and I stopped building and flying. I recently got back into the hobby my first build was a little Guillows Cub I had so much fun with it I immediately put a new project on my building board.

This kit was designed for a speed 400 brushed motor, and nicad batteries. I want to go brushless with lipo. I am not sure what motor size or how to pair ESC with motor as I am new to electric.

I do know how to build so I started the build. I will figure out the power system as I go. Any suggestions or help on how to figure that out will be appreciated.

35" wing with 350 sq in of area. I think it should come in at under 1 lbs

There was some good info there. I was glad to read it, but I am too much of a tight wad to buy that gear. I found a place called heads up hobby. great prices $2 (lightning fast) shipping. I got a motor, prop, motor mount, esc, and battery for under $50

I bench tested it seems to be good. the real test will be the first flight. I will let you know then.

wing

the wing was pretty straight forward building. It built up fast. the only thing I did that was not as indicated on the plan was added a servo rail. This was needed because I am going to add rudder control to this model. I have also decided to have one servo for each aileron so I have to go to the hobby shop tomorrow and pick up one more servo.

I hope to find time to build the ailerons tomorrow.

headsup is good. valuehobby.com is also good. imo, hobbyking is also good. usually though i refer to e-flite since most of my parts are from them.

good luck with your maiden.

dry fit/ready to cover

The ailerons are built, and everything is finish sanded. All the control surfaces have the angles sanded and hinges dry fit. I also drilled the holes for installing the servos. The AR610 RX I planned on using does not fit in the center section as suggested in the plan so I made a little saddle just right of center. where it will fit within the confines of the wing.

I have been building this whole kit with parts from my hobby box. I found a couple partial rolls of monokkote one is transparent red and the other is solid grey I think it will look good. So far I have only bought one servo, the "firepower 300" motor, ESC, and the battery pack. I think I will get it in the air for under $50

Do not use reg Monokote. It will break the frame work especially the ailerons. I had some issue
with the low temp lite covering. I used Microlite.

I had to rebuild one aileron.

finished and ready to fly

I finished the fundango today. I think it turned out real nice, I am always a little apprehensive before the first flight, but I think it should fly well. Finished weight is 15 oz. the Firepower 300 outrunner with a 7x4 apc slow fly prop is producing 16 oz of thrust. I timed the discharge of a 3s 1300 mah 30c pack, and I should get 15 min flights. weather permitting I will do the maiden flight tomorrow.

Maiden Flight

Today the fundango made its maiden flight. It took some getting used to on the ground with no steerable tail wheel, but once it was pointed into the wind it took off without a hitch. Three clicks of down and two clicks of right aileron and it was trimmed in.

it flies real well! The problem is I did not fly it so well. It is really twitchy! I have been flying planes that are a lot more docile and slightly self correcting. with no dihedral this plane needs to be flown all the time and it is also way more responsive than what I am used to. I am sure once I get used to flying it I wont want to stop.

Three flights in the morning. My daughter came back to the flying field at sundown and took some flight pics for me.

Congratulations! Program some low rates or some exponential will calm it down.

motor life?

Today when I went out to fly I noticed a marked decrease in power output from my motor. being that this is my first brushless electric plane I have no reference point for motor life.

I think I have >50 flights now, most flights are 15min or more. I think is is safe to say it has had more than 13 hours of run time. is it normal to have to replace a motor after this kind of use?

Thanks for sharing your experience.
