On my Blue Funder (built almost identical do this plane) my wings decided to fold up on me pulling out of a dive. THat's what i get for using cheapo dowels without checking the grain to make sure they ran the entire length.

Nice Videos. For a first time flyer, you seem pretty good! Did you mean Maiden flight of your funbat? You definitely are flying zero mistakes high.

The tail wag is normal on a short plane and perhaps the alignment of your rudders is not equal and they are figthing each other.

Perhaps it's the Tail wagging that got the dog excited to eat the plane.
I hope you figure it out.

New Motor & Combat loss

I upgraded my FunBat's motor to a stronger 400 size - http://www.headsuprc.com/servlet/the...lectric/Detail

It made a world of difference on my heavier Coroplast bird (20oz.). Using the same 9X5 GWS, she is a bit faster & has a lot more thrust/lift.
As you can see in the video, I still need to be careful about getting behind the power curve when down low, or else there just isn't enough there to pull me out of trouble & down she goes.

Unfortunately, I lost my first combat match today at the hands of a scratch built wing made from pink foam.
We had a head on (just off camera - but you can clearly hear it). My O ring & prop seperated - at that point, I became a glider pilot on short final ....

A short video of my first streamer flight, nothing too exciting.

Just a solo flight, no combat.....YET!

Here's my contribution. Built in two days (after working hours to dinner time).

Motor : Parkjet 2200kv Brushless Motor
Prop : 6 X 4 Carbon Speed Prop
ESC : To be Decided (30A at least)
Servo : TowerPro Metal Gear Servo X 2
Battery : To be Decided (Maybe can fit 2200mAh 3S)

I've extended the nose by 1". Does that have any effect on the CG location?
I have decided the CG to be around 1.5" from Wing Leading Edge.

Any recommendations before i maiden this weekend? Appreciated..

Nice build. Better choice on colors than mine. My kids colored mine and it is too similar top to bottom.
The 1 inch extension will bring your CG forward. Stock mine was right on the spar at 1.75". Adding a 2200mAh battery will have a significant impact too depending on how far forward you mount it. The battery position will have the greatest impact on CG. use velcro so you can move it around to find the ideal position. With 1000mAh 20C blue Lipo I'm good for 7-8 minutes for flying varied speeds.

For the Maiden, I would prefer a nose heavy plane over a twitchy tail heavy plane if I wasn't sure of the right balance. Nose heavy means a higher speed on landing and less responsive to surface inputs too.
I would set up dual rates and/or expo because these little planes can be quite twitchy. I have 50% expo on the elevator and 30% dual rate switch on the ailerons for launch. Once you're up and stable you can kick it up and roll at high rates.
Congrats on a great build

Thanks. I think i am going to at 1.5" CG point and follow your lead on the rest of the settings. The FunBat is ready for maiden this coming Sunday (at a open field). Will see how it goes...

But here's an update on the setup.

Motor : Parkjet 2200kv Brushless Motor
Prop : 6 X 4 Carbon Speed Prop
ESC : Extreme Flight Airboss 35A ESC
Servo : TowerPro Metal Gear Servo X 2
Battery : 3S 2200mAh 40C

Come to think of it, you should run a watt meter on the 2200kV 6X4 setup and see what amps it really draws at WOT. Your 40C 2200mAh batter will deliver a constant 88 amps which is why more than you need. The weight penalty in flight performance is much greater than running a couple packs at 1000mAh and 20C. True the flight time is lower but who cares, Land, pop in another pack and off you go. Better Acro and higher speeds and better climb rates if you go as light as you can.

The CG at 1.5 is at the dot for my FunBat. Maiden flight flew as if it's on rails... A little agile in the beginning but for the 2200kv Parkjet motor with 3S 2200mAh 40C battery, unlimited vertical is achieved...

Hands gets itchy for the VTO... Enjoy the sequence in this short clip.

Does this design solve the problems of the original Blue Funder? I have built 2 of them and the biggest issue is that the elevator has very little effect at low or no throttle. It also tends to bob up and down if there is too much elevator at low speeds. This makes landings very difficult.

I've tested the FunBat on slow speed. It seems to tail wag but i never had it bob up and down...
