My scoot flies just fine out of the box. No need to go and re-design it.

So, I had the opportunity to take my scooter to the field last weekend for the maiden!! I was so excited, that I defaulted to my normal 80mm battery, the 4000 mAh PRO. VERY UNWISE DECISION!! The plane jumped off the runway (grass BTW), the tail dropped, and I knew immediately that I was in trouble. I managed to get some altitude, and the plane was ultra pitchy, and was acting like a hornet in a cage. I flew it for about a minute to get used to the pitch sensitivity, and headed in on approach. I do not know how, but I made a picture perfect landing with a tail heavy tiger by the tail!
I switched the batteries, and (after my knees and hands stopped shaking) started the takeoff roll again. With the 5000 all the forward, kissing where the board used to be ( more on that in a minute ) she broke ground and a smooth, beautiful climb out ensued. I proceeded to wring this thing out!!! What an incredible flying plane, just absolutely crisp and perfect in all of the maneuvers I could throw at it. 3 minutes later, on final again, another spot on perfect touchdown without touching the flap switch. We did have a 15 mph wind as the maiden was going on, and it steadily increased throughout the day, so that was unfortunately the only flight I got on her.
Now, as for the board. I took the battery board off to run the wires from the tail under it to keep the compartment neat. As I started hooking up the receiver, I wasn't happy with any antennae arrangement I could get in the space that was existing. I took the battery board back out, and there is a HUGE cavity under there. I put a 4 inch extension on the steering servo and the retract, and moved the board and the receiver under the battery board. This makes for a perfect installation. More than enough room to orient your receiver antennae and even add a satellite if you wanted to. I used double sided foam tape to secure the board and the receiver. When the battery board goes back on, there are zero wires in the way, and the whole area is wide open, with no clutter!!!
If you are on the fence about this one, jump off, burn the fence down, and get you an A-4!! You will not regret it.

During one of my aft CG test flights, I experience a very low & slow 90 degree pitch up and the stock power system with cheater saved the jet. For me, appearance does trump performance and efficiency. Better to have additional air to the fan in a pinch than not and risk the appearance of your Skyhawk. ;)

Almost done. Need to weather right side and apply decals to ordinance and put a few coats of Minwax clear satin verathane on and will be complete...3 Photos

I have to say, I was on the fence as to the Israeli camo scheme or the Lady Jessie, and, well, the Lady won out. Really like the story of the planes history and how it came about...

I hear you, however I noticed no difference in aircraft acceleration with and without the cheater covered. The airplane is off the ground in 150ft or less either way. This is a big model for an 80mm with plenty of inlet area and so I wanted to try it. I've tried it on other Freewing models and seen the performance decrease, so I was interested to see what it would do mostly for my own curiosity. It's all about personal preference. For me, if I can improve the looks a little bit, I will, but it's a small detail that is barely noticed either way, haha!

Ran/Tom - Great job on your custom schemes.
