Default goldberg tiger 60

Ok ive been hankering for a bigger sport plane powered by electric and i love trike gear for smooth looking touch and goes, so the tiger 60 has been selected and is now in stock and im trying to figure out power system and details. I have in stock several axi 4130-16 motors, and a eflite .46. My biggest problem i suspect will be prop clearance, so im planning on going with as large foam tires as i can reasonably put on without it looking goofy. I'm thinking 6s 5000mah and a 15" 3 blade prop on the axi.
any ideas or suggestions on a power system? i have no aversion whatsoever to buying new motor for the project.

Well, I did a conversion to a clone of the Tiger 60. It is the Super Low Wing Trainer from Nitroplanes.

This is the plane [link=http://www.nitroplanes.com/nilosuaetr60.html]Super Low Wing Trainer[/link]

I am using a Monster Power 60 motor, 60 amp ESC, with a (4) 3s 2650 batteries wired up for a 6s 5300 mah battery.

Here are the parts I used.

Here is a poor video of it launching a glider and a few pictures of the way I mounted the motor.

I forgot to tell you that I run a 16X8 APC "E" prop.

This plane is such a great flying plane. It is not a total flat bottom wing. I would say it is more like a 1/3 symmetrical wing. It has a little shape to it, but not much. We, my brother, brother in and I bought them at the same time. One is powered by a Magnum 60, Magnum 90 and my E version. They fly VERY well. They fly inverted with ease, land at a snails pace, easy to see, just handle very well. About the only improvements I would do are real piano wire for the landing gear and lots more glue for the landing gear blocks. Other then that, they are great.

I have more pictures if you want to see them.

The pictures I have are of the electric conversion and the glider mount. On the stock aileron setup the torque rods are pretty floppy. So I cut them out and went with a dual aileron servo setup. Makes it much better. My brothers plane gets flutter like crazy. If he gets it to fast, you can see the ailerons flopping around. You also hear it flapping. He has so many flights on it now, it is ready for a rebuild so he is going to do the dual servo setup.

Last time I was out, I was able to fly for over 20 minutes and still never hit the LVC. The more I fly "E" power, the more impressed I get.

I like the glider launcher, have to give it a two thumbs up! [sm=thumbs_up.gif][sm=thumbs_up.gif] I'm trying a little different set up on my Tiger 60.

Turnigy 50-55-580
80 amp ESC
6S 5000mah Zippy
13x6 prop.

Will have a test flight Monday or Tuesday

Well no problems with the flight!! I need to go back out and get some flight times though. I was goofing around and didn't pay any attention to time just had the voltage set on the radio for 22.2v. When it hit the magic number I brought her down. I did prop it down to a 12-6 though and the plane still flew good just less aggressive.
