;-) seems kind of right in a way. My research turned up anecdotes of batteries catching fire after a bad crash...but I'm not sure if these disasters might not be urban legends! I'm going to be one of the some. Got pots, got sand, save $$$ You are a lucky man to have a girlfriend who shares...

Many thanks for the analysis & advice! I've had less confidence in the LIPO element of my project than any other. So, looks like the cheap charger will work & risk is manageable. I'll place the order. Might as get the boosted ESC while I'm at it. And the props I forgot. I'm pretty sure...

OK, LIPO chargers. Need one. I've done my research and realize the LIPOs are different breed, need to be treated with respect. Need to be inspected. Can burst into flame. Scary thought for a paper airframe. This one from Hobby king looks reasonably priced & delivery is pretty quick. Will...

Not absolutely sure they charged me, but somebody got dinged for $15.30 priority mail! :eek: My invoice said free shipping, so if that means spending so much on a $32 order that is fantastic service, but a terrible business model.:twisted: I'll have to check my credit card statement. The...

The Flysky FX/RX arrived from HobbyPartz today. A lot quicker than expected - they shipped it priority (pricey) instead of my requested free shipping. Nice looking units, but missing were the instructions (can be downloaded in pdf form, but that's 22 pages to print), the programming CD and the...

Bottom line, I'll be thrilled if I can use the throttle so that the phase 1 Se5a porpoises around an ascending, level or descending line of flight. Plus banked turns induced by the rudder, with help from dihedral. This will match my RC piloting skills nicely. Have no fear, the plan is for...

All airplanes pump (porpoise) a bit during flight. The vectors driving pitch are in dynamic, not static equilibrium. The P51 was notorious for porpoising badly in a full throttle chase - throwing aim off and saving many an FW 190 pilot. Excess up elevator tends to magnify the problem. This...

Looked into those sunglasses-they look much better than I thought they would. I sort of envisioned Groucho Glasses - the ones with the fake nose, eyebrows and mustache. :cool: Someday it might be nice to pull one of those tiny lens units out of the housing and fix it in the open cockpit...

Ordered the HobbyPartz 2.4 6 channel. Good price, and gets good reviews. A no brainer. Went with the 2 gram hobby king motor Bought the 4 g speed controller from hobby king - oops. my mistake, should have ordered the 2 g one with booster. Too many numbers on my set-up notes, I chose the...

All the RC stuff is on order, except for a basic lipo charger that will get me going. I'll have 3-7 shipping days to mull over control linkages and motor mounts. Weather is going to close in soon so I'll need to find a big gym or maybe sneak into one of the local covered sports arenas. Paper...

The more I look, the more I like that Hobby Partz rig you came up with. Gets good reviews so far as I've seen. Maybe just go to a 2 cell Lipo and adjust excess voltage with some resistors. Weight will go up, but not a show stopper. I just wrote my official introduction to the Zealot board...

Hello zealots, just getting around to introducing myself. I design flight worthy card models in light weight paper and found the Zealot website while Googling how to outfit my 17.5 g Se5a airframe with suitable electric propulsion and TX/RX. Very knowledgeable member Schorhr has been giving...

The smallest ducted fan I had been able to find was 49mm - too big even for my Tunnen. Thirty is doable and 20 opens up real possibilities...if I can just figure out a working RC rig. Engineering wouldn't be fun if it wasn't hard!

Guess some more research is needed, I'll ask around concerning voltage compatibility. Right, two servos for controlling elevons like the F102 or F106 or Mirage. Or like my big ol' display Saab Gripen, the only delta in my fleet to date. Good time to ask about very tiny ducted fans though -...

Great tips Schorhr, you certainly do know your way around components. Psychic too! I was about to ask you about battery chargers but you read my mind. So, At 2g and $10 US, what's not to like about the speed control with a booster? Can't actually get any ultralighter with my Se5a and still...

"Fly-by-wire" in USA aerospace terminology is a control surface that is controlled electrically, rather than by the older mechanical or hydraulic means. Like what's used in the F16. You command of English is so good I get a bit careless with the Americanese jargon! Anyhow, I'm leaning towards...

My 1:48 Spitfire is low wing and incredibly stable just from the natural dihedral that results from it's elliptical wing. Only gets aerobatic when I dial that in! Been looking into coil actuators; all the ones I've seen on the web seem set up with little lever arms, like tiny servos. Have...

F4F Guadacanal Here it is painted circa 1943. That's one of the great things about paper. So easy to change the color scheme.

I sketched out a rigid design once using sturdy board (foam sandwiched in paper) for the internal frame. It's easy to work with and gives a strong yet springy frame. Mylar for both the external skin and the gasbag(s). Figured it would have to be about 12 feet long to get a decent payload...

The wing is pretty ambitious on this little model. It has a fair amount of dihedral, but that' not easy to discern in the photo. Zealot forum seems to scale my jpegs, so what you see is bit smaller than what I sent (or thought I sent. The cool thing is the wing is a good approximation of the...
