Could you post some statistics on the plane, please? I'm looking for flying weight, etc.

Also, is the original motor direct drive or geared?

Would you be opposed to making some minor modifications to the motor mounting area to accomodate an outrunner?

I have the CG Eagle 400. I use a Park 400 Outrunner (ditched the gear drive) and GWS 8x6 prop. With a TP 3C 1320 lipo battery, I get 20 min plus flight times and very good overall performance. To install the outrunner, I simply built a small motor mount out of some spare balsa. Lipo fits nicely under the canopy (that I painted black).

The Tiger is only slightly heavier, but has less wing area, so I suspect the setup I have on my Eagle would work great for it. In fact, I hope to buy the Tiger and transfer the guts of me Eagle over to it (being flying the Eagle for months now....ready to move up ).

Hope this helps a bit, and good luck to you.

Used a parkzone 370 outrunner on my eagle 300 but just finished it last night so no flight report yet.

I have a wattage Crazy 8. About the same size and weight. I'm very happy will mine. I'm running a Mega 16/15/5 direct drive, A castle creations phoenix 25, A Thunder Power 3s 2100 prolite pack and an APC 7x5 eprop.

SlickZero,

I have been a fan of the the look of the Tiger for quite some time, in fact I had a 40 sized Tiger about 8 years ago that was a lot of fun. I recently picked the Tiger 400 up to have some fun with, and I immediately replaced the motor with a Hacker A30-22S brushless outrunner running an APC 8x6 prop coupled with the X-30 speed control. I made a custom laser-cut firewall for the motor, and it fits great. I beefed up the battery mount to accommodate a larger LiPo battery (2000 mAh), and the results are pure fun. The plane takes off in about three feet, and accelerates vertically non-stop! If I had to guess, I would say that it is climbing at about 3500 feet per minute! I have some video at home, and I will have to post it later. I highly recommend the setup if you want all-out performance.

Off the power, the wing loading is so low that the plane will stop in a 5 to 10 mph breeze! The landings are very slow, though I would consider beefing up the gear. The current gear is very flimsy, and cannot stand much more than the most gentle of landings without bending.

I carry the Hacker A30-22S, speed controller, and I would be happy to combo them with the laser cut firewall if you are interested. My contact information is on the web site, or you can send me a PM, if you prefer.

Default My Tiger

My tiger 400:

Himax 2025-4243 geared 4.3-1
Kokam 3s1500
APC 10X3.8
I think it has a Jet 12.

It will go!!!!


You will notice the landing gear improvement. Also the exit in the bottom of the fuselage for cooling.

Ragbag,

I like what you did with the gear. I have been considering cutting a set of aluminum gear, but the added wire might just do the trick. Out of curiosity, did you do the mod before you flew or after the first landing?

After the first landing. The gear splayed, didn't like the take off either. I think it might be a little over powered for straight flight. I don't 3D so I'll never know.

I fly off grass so I always have larger wheels also.


Too many projects, Too little time

So many cats, so few recipes.

Default Tiger video

As promised, here is a link to a very short Tiger takeoff video. You will have to excuse the poor quality, it was not intended to be published.

My Tiger 400 has the same setup as my Eagle 400 (in fact, I took it out of the Eagle when I had a pretty bad mishap:

Park 400 Outrunner
GWS 8x6 prop
TP 3C 1320 lipo battery

Before I deployed over here (Baghdad), I put the 2100 Lipo in once, and it performed quite well. Flight times with the 1320 are 18-20 minutes. I suspect that will be well over 25 min with the 2100.

The landing gear does suck though. Absolutely need to do something about that. If anyone has any suggestions (very specific for ordering, please), I'd be glad to hear em. I'm going to see if I can have the Tiger and perhaps another Eagle shipped over here. Don't have much time to fly, but do need a release every now and then.

Thanks for any input.
Bob

You are right Thunder, given the circumstances, I am lucky to have any video at all! Thanks for giving up sleep to film the plane. We will just have to blame it on all the wind at the field that day

I finally finished the Tiger II. It was for my son who is not into 3D, just sport flying with a few loops, rolls, etc..
So I decided to try an inexpensive set up. It doesn't have unlimited vertical but I was surprised how strong it flies with this set up. No problem with big loops and stall turns from level flight.
18.95 BP-12 Brushless Outrunner
29.95 BP-15A Brushless ESC
1.55 EP-8043 Slow flyer prop 8 x 4.3
2.50 HE-PS-30 Prop saver
24.95 E-3-700 LiPoly 11.1v 700mah
77.90 Total
I could use a larger mah battery but the 700 was the only extra one I had around. He only flies about 5 min at a time so it hasn't been a problem.

Slick,
Looks good, I thought mine was overpowered, never thought to try a BP 12. Have one of those in hand, might replace my Himax and use it on something that needs the power.

Try to get some photos of the setup, they might help the next guy do his.
