My first sailplane. I didn't care for the manufacturers graphics so I airbrushed some color where I thought it needed it most.

I also pulled my daughter Kristin into service for the photo shoot in the 103 degree afternoon sun... what a trooper! Seriously.

Will maiden later this week.

Although I'm quite new to helicopters I will be the first to lay my money down on a 450 size version of the Sikorsky X2. Seriously.

Update: There was a Chinese company producing a 450 size copy but the company folded and shut down their website before they worked out all the bugs in the first batch of models sold. Walkera has a 250 size version on its website but it is not available for sale as of this date.

Sikorsky X2 Technology helicopter achieves 250kt - Sep 2010 (3 min 57 sec)

Blade 120SR my first helicopter.

Programed my DX7s per RCHELICOPTER.COM's Getting The Most Out Of Your Blade mSR/X & 120SR and motified/protected the tail rotor motor wiring with heat shrink tubing. I need to adjust the rotor blades a little more though.

And still struggling to get a smooth start into a hover.

Update 3 June: I need to get a bigger apartment or improve my flying skills. I've managed to get a hover and keep it fairly stable for 15-20 seconds before it gets away from me. On the plus side it's a tuff little bird that is still in one piece after bouncing off bar stools and table legs a few times.

Update 4 June: I have three 500mAh batteries, (1) E-flite 12C and (2) Tenergy 15C, and each time I change batteries I need to retrim. I'm told this is typical. I have managed to increase my hover time to 3-4 minutes so I am making progress.

Update 6 June: I seem to have it sorted out pretty well and can tail-in hover for a full 5 minutes. I think the new rotor blades helped.

Update 15 June: My apartment has gotten bigger. Yup. That must be it.

Kits and plans here: https://www.rcgroups.com/forums/show....php?t=1012551

Motor: HXM2730-1700kv
Servos: Hextronik HXT900 9g
Prop: APC 8x6 slow fly
Spinner: DU-BRO 1-3/4" Dia.
Battery: Gens Ace 800mAh 2S 20c
Weight with battery: 10-5/8oz. (303g)
Paint: Createx Opaque (red & white), Testors (aluminum), SpectraTex (for the sky blue; custom mix)
Panel lines: Fine tip Sharpie

Purchased this as kit last year and after starting it I put it on the back-burner until the beginning of May. Made the exhaust stacks out of scrap foam that came with the kit and shortened the ailerons at the tips for a more scale appearance. The leading edge also has a wood dowel set-in for added strength from the root to the tip of the KF airfoil. The bend was made by soaking the tip of the dowel and nailing it to a board overnight to match the curve in the wing tip. The whole airframe was treated with a mixture of lightweight filler, WBPU, talc, paint (white) and water, than sanded smooth. I took a little to much off the underside though . The joint where the wing meets the fuselage was filled with a epoxy- micro balloons mixture using a Starbucks wooden coffee stick to get the curve constant. Ditto for the scoop on the belly. The stars were painted using Grafix Low Tack frisket film that I got at Michaels. The canopy was all hand done after making a template from Ken's plans that I cut out and penciled onto the fuselage.

Motor: FancyFoam 50g 930kv
Servos: GraysonHobby 9Gram Micro Servo (had them sitting around)
Prop: APC 10x4.7 slow fly
Weight with battery: 16.1oz. (480g)

I used the FancyFoam plywood motor mount installed with slight right thrust, and the landing gear kit. I CA'd a piece of fuel line on the inside of the axel and a self-locking nut on the outside to reduce wheel wobble. I also stiffened the fuselage by adding a 5mm x 3mm x 24" carbon fibre strip set into a slot on the inside of the outside fuselage doublers (each side) from the back to the underside of the wing for extra stiffness. If you go this route mount the CF about 3/4" down from the bottom of the horizontal fuselage section so that you have room for the servo pockets for the elevator and rudder. I found that the control rods for the elevator and rudder flexed a bit but solved the problem with a couple of cable ties used as guide/supports.

Went through my typical ground check and range test before the maiden and took her up. NO TRIMMING REQUIRED!!! Seriously! Put it through its paces and brought it up and killed the motor... glided beautifully. Roll, perfect. Knife edge, ditto. Elevator to harrier landing, all smiles.

Second flight, new battery and all I can say is WOW! Pointed it skyward and gave it some extra throttle and watched it climb until it spit off the prop. Brought it down to a perfect dead-stick landing with an ear-to-ear grin.

Getting all the parts together for this beautiful airframe.

Motor: Hacker A50-14S V2 Outrunner 425kV
ESC: Hacker X-70-SB-PRO
Battery: Thunder Power 5S-4400mAh 25C
Prop: APC 16x12E
Servos: Hitec HS-5496MH HV Digital (all around)
Retracts: E-flite 25-46 tricycle, SebArt stock struts
Pilots: (2) Pete's Pilots 1/9 scale jet bust

Motor: Eflite Park 480 1020Kv
ESC: Thunderbird 36A
Battery: GENS ACE 3S-1550
Prop: APC 11x5.5
Servos: Hitec HS 65 (all)

This plane has a number of fans. I am not one of them. The plastic control horns that you have to fabricate out of sheet stock have caused my ailerons to bind-up twice! Replaced with fiberglass horns. The tailwheel as designed will not track straight. Added a fuel tube collar CA'd on the inside and a lock nut on the outside, and built up the axel with shrink tube to eliminate the wobble. And don't get me started on the motor mount.

Update: O-ring mounted plastic motor mount replaced with plywood firewall/motor mount. No more broken o-rings in flight from vibration and/or fatigue.
