Soldering battery tabs

Is there a good (versus bad) way to solder or attach battery tabs to batteries? I notice that some of the commercial electronics with batteries (shavers and so on) seem to have the tabs spot welded...

RE: Antigravity model anyone?

The problem with the ionized air flow idea is that these gadgets also work in a vacuum. Hard to explain that one. The need 10-30 kV to work, but only draw about a milliamp. You can build a power...

RE: Antigravity model anyone?

Nope, not these ones. There is no plate under the model. These things are a balsa triangle with about an inch or 2 of aluminum foil on the bottom, and a single string of magnet wire a couple of...

Antigravity model anyone?

Anybody want to give this a try?

It actually flys. A different kind of electric model. How many LiPo's would it take to make 17.5 kV?

RE: Electric Sticker Shock

Yes, thank you.



Thats because you get shocks from those electric guys when you shake hands with them.

RE: Electric Sticker Shock

At our club everyone who has tried electric has ended up throwing it in the closet. We don't have a single electric flyer. Same with several other clubs we do events with. The problem is knowledge,...

RE: Electric Sticker Shock

Hey, us gas guys aren't the only ones who move up. First there are the little foamy park flyers, then you have to have warbird, then a 3 D package, then a multiengine. Of course you need Lithium...

RE: Electric Sticker Shock

Sure, but why would I do that? My "cheap Chinese" Vmax is a great engine for training and just goofing around. I could install a Saito 2 cyl or an OS 4 cyl for many thousands of dollars and really...

Electric Sticker Shock

With my growing interest in electric flying I thought about looking into converting a .40 trainer to electric as a learning project. What I learned is this (Hobby-Lobby prices).

RE: Onboard electric starting

Thanks for the link. These bearing units look like they would be the solution to my starter plans. Now I have to think of a way to house the bearing on a shaft that connects the threaded end of my...

RE: Onboard electric starting

How does a one way bearing work? Spring loaded dogs like a pull starter? Or something flexible that only catches one way?

RE: Onboard electric starting

Thanks for the link info. On the Hobby Lobby unit I assume there is an over running clutch or dog setup in the gear reducer unit on the motor itself? The gas engine end of the drive shaft ends in a...

Onboard electric starting

Does anyone have any info about on board electric starting for glow/gas engines. I have seen a few of these, very neat. I can see hooking up a cheap electric can motor to the back of an engine, but...

RE: Flying wing in Indiana Jones

Jan

Thanks for the reply. Great scans, neat designs. Apparantly the Horten had a lot of potential. Looks like Burt Rutan got his "rudders on the end of the wings" idea from the Nazis!

Flying wing in Indiana Jones

My daughter and I watched a tape of Indiana Jones the other night, Raiders of the Lost Ark. Hadn't seen it for years. My attention was drawn to the German flying wing featured in the movie, the one...

Wing spars for large scale foam wings

Hi. In going over the plans for a Lancaster I was not impressed with the wing. This is a 100 inch model. The designer specifies 3 straight foam panels glued together on each side with no other...

RE: Electric flight is still too young

A previous post suggested listing details of electric setups so that those of us struggling with electrics could start to build experience with the components. What motor and esc are you using, and...

RE: Electric flight is still too young

Flypaper - Guilty as charged. I am not up to snuff on the latest in electrics. Just what I read in the ads (Kokam said 5C in some ad I read, can't find it now). I'm not trying to be a wet blanket on...

RE: Electric flight is still too young

I think the other thing about electrics is the 3-4 minute fly time. When you get into bigger planes and have a hot setup, the LiPolys will probably give you less than 5 minutes. Then what? You do a...

Great post, you wrapped it all up nicely. Us old glow/gas guys will get into electric when it makes more sense to do so. Some of the electric enthusiasts have countered with the...

RE: How does a brushless motor work?

RedB,

Great explanation, thanks for the info. Cleared up a lot for me. I play with unipolar stepper motors and controllers for CNC gadgets, but a 3 phase brushless motor is a new critter for me....

RE: Electric flight is still too young

I think that things will improve in electrics over the next few years. I don't understand why at least one manufacturer doesn't grab the opportunity and put out clear and instructive ads, instead of...

RE: Electric flight is still too young

Excellent stuff, thanks for your advice. I agree with the previous posts that electric is introducing lots of new people to RC modelling. We desparately need this, the glow crowd is getting old. The...
