Hi Phayd,

Thanks for the input, consider them added for the next release, probably next week.

I'm always amazed at how large this list has grown!

Hi Bldrums,

Bashing normally means that people are saying negative things about something. "Kit Bashing" would mean that people are saying negative things about kits.

Normally, when speaking, bash would mean to strike or hit.

I'll try and make up a definition and add it to the list.

Hope this helps.

Thanks for your help.

What is "bashing" ( or sometimes called "kit bashing" )
I don't know the origin of the term, but it means to heavily modify the model when you're building a kit. From the way I've heard it, it seems to be a very old term, used mostly by guys who have been building kits for a long time. There's something humorous in the term, but not knowing the origin, I don't get the joke. It may simply be the similar sound between "kit building" and "kit bashing".

Kit Bashing is not a derogatory term, much like hacking is not really a derogatory computer term. Like Mike said, it is to modify a kit in ways not intended by the manufacturer. For instance, putting two engines on a LT40 is a kit bash. Clipping wings is an easy kit bash. Making a Senior a biplane is another kit bash. Essentially you perform a kit bash whenever you stray from the manual.

Just my two cents: V1 means, the maximum speed in the takeoff at which time the pilot must make the decision to , in a nut shell, take off or abort the takeoff.
V2 means, takeoff safety speed, thus when the airplane is rotated for takeoff
These terms are normally used with high performance aircraft (Jets), V1 was derived from the field length to ensure that if there is a problem during the takeoff roll, the airplane would not end up going off the end of the runway. All Jet manufacturers include a table in the flight manual with runway length minimums based on aircraft weight and air conditions ie., density altitude, temp, pressure altitude and so on. If the aircraft is limited to say a 5000 foot runway, the decision speed or V1 would be roughly half of that. During the takeoff roll when the airplane safely passes V1, with no problems, then V2 is called and the airplane is rotated and off we go..... Hope this helps

When some one says scratch built. Does that mean that it did not come from a kit or does it just mean that you built it yourself?

Thanks

Default RE: RC Universe abreviations, terms and acronyms list

Scratch built, to me, means you build it just from the plans,,, no kit. You can order laser cut parts if you provide the plans to someone who does that. But to me, scratch built means that, from scratch, also meaning cutting ALL the wood. Altough laser cut parts are excellent. I've never done that yet, but its in my things to do Its just like food from scratch. For example, making soup from scratch. You start out by making the stock, from scratch. You don't buy chicken or beef broth, you make it yourself (which takes some time). You cut all the veggies, meat etc yourself. I used to be a chef. Hope this helps.

Default RE: RC Universe abreviations, terms and acronyms list

I was wondering why he could not give me a mfg. name. I guess in reality he was the mfg. Would this make the plane worth less money?

Thanks

If he's a good builder, no it wouldn't be worth any less money. In fact probably most scratch builts are a great deal better than ARF's. It also depends I guess what kind of hardware is used, if it includes the receiver, servo's etc. I'm still an "amature". So take what I say for what its worth

Joe:

Building from someone else's plan is not scratch building.

When I started even die cutting of kit parts was rare, you had to cut all the parts from bare stock wood. Or in the case of a Joe Ott kit, the formers were paper card stock. But you still had to cut them out. Building from plans is no different from this, other than having to gather the wood and other parts separately.

Scratch building was usually done by design as you go, although some people did draw rough or even finished plans of the plane. I still mainly design as I go.

In this day when people claim to build an ARF, many have also decided to claim scratch from a published plan. It's just not so.

Hi,

Thanks for the input, I've added Scratch Built, Plan Built, Kit Built etc. to the list for next publication, probably in a week or two.

Bill,
Thanks for correcting me. As I told him take it for what its worth, because I'm still kind of new at this. I guess I got the mis conception from a guy who sold me an adjustojig about a year back. I probably mis understood him. I was telling him that in the future I wanted to start scratch building. He was very nice and sent me plans for Das Ugly Stick, and a copy of the old article from MAN. He just sent it, didn't ask for any $$. I think he did that just to get me started learning how to build from plans and cutting my own wood. And I "ass u me d" that's what scratch building was. Now I know, and still a ways away from that. I guess that's why that forum is called scratch building & design
Thanks again!
Joe
