Coupon and gift certificates at tower has lead to another plane being added to the fleet. The Phoenix Piper J-3 Cub GP/EP/Gas ARF 90.5" is a stand off scale model that has few oddities as far as scale fidelity. Some profiles area a bit wonky but over all she's a nice plane. The covering is absolutely flawless , I mean zero buggaboos anywhere. The wood build part is very well done although tick heavy at 14# AUW which give a wing loading of 25 oz./sq.ft. She flys well enough however. Supplied tires were rock hard an I replaced them with inflatable DuBro Big Wheels. The landing gear is not articulated like the full size and has springs instead of bungees but with no movement it's a moot point.

The dummy engine supplied was horrible and hit the dust bin. I bought a 1/5th scale e 65 HP Continental engine kit from Top Notch Products as a replacement.
Graphics are from Callie, the stock ones were wet slides which I don't like. This brings up one oddball time that of the scale size. She's 4.75 scale which is a tick bigger than 1/5th by a 1/4 or so which makes the engine a bit small,the graphics were scaled up by Callie.

The model has flaps which were not a stock J-3 item but were on the PA-11 which was a J-3 production mod. But as always you look long enough and you'll find a prototype for anything. Control horns are different and actually pretty neat but they could have made them yellow. I went with a 1.20 glow equivalent sized AXI 5320/18 turning a 16 x 10 prop...Continue Reading

Finally got around to building a second work bench for the shop. Both will get paint in spring and walls will get sheet rocked at some point. New steel shelving helped organize things a bit and gave me a place to setup my old school rack stereo system

The ol' gal was getting pretty ratty and needed to be freshened up a bit. Black cover on the entire nose was removed, oil and glop cleaned off then new covering installed. Engine well coated with thinned epoxy mix, new Dave Brown engine was mount installed, new windscreen and side windows made up and glued on along with some minor patches on the fuselage. I made up a new ignition system which I downsized as much as possible, made and installed new switch for same with servo and micro switch and topped it off with a 1S 1800 mah battery. She's a very over looked plane form SAM competition and flies great in lift. She also had a new 6 channel Hitec Optima receiver put in to keep her happy and on track.

New to the fleet to fill the want of a biplane even though technically she's a sesquiplane and the fact that I have never had a World War 1 aircraft. Not much to say on the build as it was pretty straight forward. Scale fidelity isn't the best but for the money she'll do. Wire braces on wings were a bit fiddly but not a big deal to assemble.

I bought the entire 'package' deal from Maxford except the prop which is an old AHM 13 x 6 wood job. I didn't use the supplied graphics instead getting a new set from Callie at Callie's Graphics. She does great work and had them already on file. Added little bits like the engine intakes and repainted the outer wing struts to a more wood colour from the supplied yellow.

Wires on landing gear are next once I sort out where to anchor them. Two 2200 mah 3S lipos get stuck in her front belly and balance was spot on off the bench. Maiden flight was done under less than ideal conditions with a bit more wind than I would have liked and she handed it like a champ. A few photos attached.

She's done. beings I am a slob there are a few little ugly bits but overall it came out well. CG is spot on at 70% of chord or 5 1/4' back from leading edge. Weight is 23.6 oz with battery putting her just under 10 oz./sq.ft. Wing tips were an absolute pain in the butt to get right and they are right. I had some control horns from sailplanes laying around and they are perfect for the job. Plus they were easy to install with a slice of a hacksaw blade for the slot and some CA. Flight test later when the wind isn't blowing at 35 knots. So until next time, save chicken fat, join the WACS, don't take any wooden nickles. Always look skyward unless you're walking down stairs. Never pee or spit into the wind Also, how can you have any pudding if you don't eat your meat?

Last build report for a while as she's ready for covering and it'll have to be nice open window weather to work with the dope.
Dilly dicking in the shop today finishing up the odd bits like fixing the cheeks on the nose, installing pushrod exits, finishing off the hatches and hatch retainer and hold downs in the interior. The nose cheeks were a poor selection of balsa and every other time I would pick up the model b the nose they would snap off. I put a space piece in between the top of the cheeks to stiffen them up and it seems to work well. I found an appropriate wheel made of wood in my junk so it got the call needing only repainting. Now to find a place to put her so she don't get broke.

Steady on with hacking up more balsa and basswood. Finally sorted out the battery fitment and it's tight but works. Building sailplanes helped here where stuffing 3 lbs of sausage into a 1 lb case is pretty much the rule. Radio bits are also in after thinking about how that was going to happen. Tail hold down is a little odd as wanted the rubber bands to not be bearing on the covering. I put the front peg inside the last bay of the fuselage with a carbon fibre rod. Currently working on hatch hold downs. I didn't really want two hatches but it had to to go that way. I could have made one hatch but was concerned about taking out the bottom cross member which is in a lot of compression holding the shape of the fuselage and it's widest point. Onward today with more shop time.

Still slogging away. Decided on a couple changes as didn't know if I had enough rudder area so I cut out new vertical stab bits and made it bigger. I also didn't like the spindly pylon mount so I cobbled up a more standard one. Bare bones (no covering) weight so far with power plant, 2 HS65 servos and 1300 mah 3S lipo is 16 oz. Wing loading of 8 oz/sq.ft needs to be met for SAM competition which comes out to 19 oz AUW so it'll be close.

Hacking away bit by bit each day making progress in leaps and bounds. No hurry, I'm retired and have gobs of time to do nothing. Covering will be Polyspan and dope, polyspan is in the post and I have Brodak's nitrate and butyrate dope in the shop. The bolt on nose section will allow for switching to an engine setup if I should decide to go that route. It's possible she could get a glow .15 for SAM Glow class competiton, we'll see. Already eyeing up next plane...hmmmmm

Good day to work in shop with 30 kt winds and 40 temperature, so I fired up the heaters and had at it. Horizontal stab is basically done after figuring out how the put the elevator in. Elevator on one side works well with old timers as you really don't use them a lot except for climbing to keep the nose down. Still have to sort out the vertical fin and rudder which I might do tomorrow. She's coming along nicely I think.

Making progress by hacking away a little bit everyday. The balsa from National Balsa is outstanding stuff and make the work a bit easier. In my old age I don't built as well as I once did and managed to bugger up the pylon, so a new one was cut on the bandsaw. While i was at it I decided to go back the the original wing mounting system instead of the Holman supplied parts. I'm also debating with myself on the covering still. I am leaning heavily towards using Polyspan and dope for something different and to give the old timey look.

Stared on a Lou Garami 1941 Strato Streak 52 build . She is a bit different as most of the old timers I've built have been the large antiques and this is a little guy. Think I've settled on a Hacker 480 size motor with a 18 amp ESC amp. She'll probably be a rocket but that's OK with me. There's some interesting engineering ahead converting this to radio control from a free flight design and brain is at full throttle.

Maiden went very well indeed. She flew right of the bench with no trim needed. CG at 55% is spot on and despite her size and ungainly looking dihedral she'll turn on a dime. The .32 size motor is just right giving a stately climb that's no too fast but not slow. Even with the cool whether for first flight she caught some lift and did the 'going up thing' but coming in at 8.5 oz./sq.ft. wing loading it isn't surprising. Couple that with the 14" cord grant X-10 airfoil she just floats on and on.

Only taking about 2 1/2 years to complete, my LRB is ready to fly. Retiring then moving to Delaware took a chunk of the time up,then I had t reestablish my shop to working order and get my butt in gear to finish her. Weather will hold up the maiden now unless we get a break which does happen once in a while

The Electra 2 maiden went exceedingly well with her flying spot on right off the bench. Despite the slightly heavy weight she has the stuff that good sailplanes are made of. Climb out with the Powerline 1025 is about 2200 fpm which is spot on for my application in ALES flying. After goofing around a bit I found some nice lift and let her ride it out and she did it in grand style. CG is right on the money @ 102 mm and all the bits work very well indeed. Second flight was about 30 minutes after a relight at 75 foot from the goofing part mentioned. She has good visibility at altitude and it steady as anything. I think I'll keep her. See attached odd photos from build.

Got two days off and got some stuff done on the new toy. Fuselage is done and the wing setup will be up soon. Pretty much standard assembly proceedings after dry fitting the parts to determine CG Servos are at rear of canopy opening, ESC slammed all the way forward behind the motor which required soldering motor plugs on in reverse and 1300 maH 7c 3S TP lipo as far forward as it can co and I'll still need about 2 oz. in the nose. Some pics attached to laugh at....Continue Reading

Checkin' this chicken over some more and dry fitted the main bits together to see how she looks. Finish is good but not the shiny waxed 26 coats of hand rubbed street rod with a big block blown Chevy engine sticking out the hood lacquer look, but a slightly matte appearance. I like it and it not going to matter at 2600 foot or heading for the tape anyhow. I see her as a tool to do the work I want to do, so the look is fine.

A bit hard to see the slicker than owl snot setup for the elevator horn to make the stab removal. Look close at second pic and you'll see a piece of brass tube that accepts a pin on the stab. The brass tube is attached to a ball link then is connected to the CF bowden rod.

Some other pics as well for short tour....Continue Reading
