The LAST Thur Begginer RC Show! (Q/A)

[Robertico59]

cool

[Imprezaman555]

on free flight aircraft (for those who dont know that's no control imput whatsoever, and none so far use gyros) the cg is around 1/4 forward from the trailing edge. If you design a plane well aerodynmically, you dont need any gyros for the plane to fly with a cg that far back.

[MrScotini]

hi can the glider thingy magige fly?

[livvidd]

regarding lipo's: whats the "c-rating" meant to denote? great vid

[djmedic2008]

constant burst rate :)

[xmodscarbonslost]

It has to do with the discharge rate, take the milliamp hours of you battery, for instance 2200mah divide it by 1000 you get 2.2 the multiply that times you "C-rating" and that is the amps you can pull without damaging the lipo.

[nepoereh]

in the mig 15 the c-g is way back that the pilot have to cheap the nose dawn using elevators

[thomdoe]

does anyone see in all the videos the chair to the left of "Dave" is shorter ?

[burt2800]

i like that sentence: "im just speking generally but thats basicly what ive seen." i don' t know why but i nearly killed myself laughing.

[Elderbloom]

nooo!!!! i need this rc show! i need it!

[diegoXm94]

NOOOO i want more classes u guys r cooll!!

[RCEbooks]

It's spelled "Beginner".

[robohobo9000]

dave should make a video on skipper

[buckeyarnold]

not exactly...it's about re-directing the lift. It makes it more stable by re directing the direction of the lift. Read up on some pilot books. There are many engineers that can explain it better.

[airlinerdude12]

yes i know. i have literaly made hundreds of those 3 channel planes.

if you make an imporvement there is always a sacrafice!

dihedral gives more stability but lessens aileron turns. it also is a more sucpectable reason for my adverse yaw on my big plane?????

[devindied]

Another senario is if your BEC is rated for a 3-4 cell lipo, .LOOK CLOSLY!!! Sometimes it will say 3 cell with BEC and 4 WITHOUT! ie. cut the red wire. So using a seperate battery is somewhat of a hassel in some cases, not nessisary in

[devindied]

And for the other question, running a seperate battery in an electric plane somtimes is a GREAT idea. For example, if the BEC on your ESC is rated for only 5v 2amp, or only 2 or 3 micro servos, and you want to put it on a larger plane that requires 4, you need a seperate battery. In the case of smaller aircraft, 3lb. and below, generally you only need the BEC power for your micro servos. others, but is usful in some

[devindied]

I'll answer the first 2 questions. Dihedral is great in begginer planes. It eleminates the need for ailerons as the plane can roll about 45 degrees max and make a turn. It does this by increasing the airflow, and lift over the opposite wing. When you add right rudder, your nose points quickly to the right, thus increasing the speed of your left wing while in turn decreasing the speed of your right. That's how it banks.

[justfly60482]

Thank you, have been very helpful.

[katanamd]

I also think you should bring up how weight will negatively effect any plane. Weight is very often over looked on models, and if lightened enough, will increase the maneuverability more than most people would think.

After that bit of constructive criticism, I would like to add few positive comments. I think you offer very good help and hints, and would like to see the show continue. I'm sure the show has shown many people how great of a sport modeling is.

[katanamd]

I just want to say that your wrong on some things, but I still think it's a great show. I would just like to see you do more research on things before you answer questions about it. For example is the dihedral, depending on the type of plane you have, it may make it more maneuverable. I have a plane that I designed and it has a little more than that foam example plane in the video, and it can prop hang and do rolling circles all with no ailerons, but yet it can act as a trainer on low rates.

[annihil8ted]

thanks dave. My shumate f 15 is ready to go with the gyro.

[davetowell1]

When is the new schedule out?

Need weekly fix! !!!!!!!!

[FREAK9364]

Dave, in every other video, you have a haircut. Wierd. Its almost like you grow your hair and get it cut every day lol. BTW: Top notch videos Dave!

[leonscottkennedyre4]

nvm didnt watch enough lol

[mgrande11]

Cool my question made the show!

[leonscottkennedyre4]

which 1?

[mgrande11]

The cg balancing on warbirds at 7:31

[jr52990]

which one was it?

[Jabbakahut]

Thanks for all the great shows, know where I can find some tips on how to fly my Blade400?

You've sold me though, I will eventually get into the ducted jets.

[ymanganelli]

Aweee so sad this was the last show :(.. But hey this was one heck of great project from you guys.. you did an awesome job so far no one has done it but RCSuperPowers cheers and good luck in your coming projects....

[ApOsTle51]

thanks guys , helpfull stuff as always ;)

[2deluxe58]

oh ver, oh veryyy nice

[crookedtool]

I can't believe you guys don't know how a dihedral wing works.

Basically as you roll left or right, one wing becomes parallel to the ground, thereby providing more lift, causing the plane to roll back the other way until the opposite wing becomes parallel and the same thing happens. This "self-righting" behavior is what makes it stable.

[myrandomspaces]

"Oh look here comes one now"

*object comes from off screen lol nice

[hypnolobster]

Misspelled "beginner" ;)

[moneybagz609]

hi Dave what ESC and motor did you use for EPP Extra 300 and what does GWS stand for .

If you can, can you please put a link for your Extra 300 ESC and motor. Thanks Dave

[SomeUselessGeek]

Thanks, Dave, but the name is actually Schrader. Anyway, I was talking about the relationship between prop size and motor current versus battery voltage.

For instance, I run a Welgard 2204-1400 on a few of my planes. That motor tops out at 7.5A. With three cells you hit that with a GWS 6050 prop. Unfortunately, that prop vibrates like nuts. At two cells that motor hits max current with a GWS 8060 prop.

So, sizing the prop to the battery is a valid way to match power as well.

[lyleattack]

Jet engines are pretty cool, but i have seen rc planes with pulse jet engines. They are so fast its insane, but there is little to no control over speed, the one i saw its only control was when it ran out of gas.

[twanna44]

no i love the begginer show

[dragonmertstar]

hi dave, as the usual verry intresting and enjoyable :D

[GrateGenin]

You have so much guts making those mods on a beautiful jet. I'd never have the guts

[taofledermaus]

I think the dihedral works by lowering the center of gravity to a point below the aircraft. It's sort of like ballast on a ship, without adding more weight.

[revmkell]

dihedral works because a level wing lifts better than a non level wing, I know it sounds dumb but that's how it works!!;-)

[taofledermaus]

I think it would have been helpful to show how a total beginner can learn to fly. From showing a PC trainer, to showing a beginner in the field being instructed by a veteran, maybe using a training patch cable between two radios. (do they still make those?!) I taught myself to fly but there were many unnecessary crashes too.

[drider400]

i agree soooo much:)

[auburntaco]

Keith is looking particularly dapper in this vid.

[joegadd]

by the way, when do you get back to vtol

[joegadd]

is the f-117 kit you guys sell good for beginners

[RCFLIGHTHELP]

NOOOOOO its hard to fly and build get a wild hawk

[joegadd]

thanks, wouldn't want to crash a new airplain

[azh01e]

Thanks for helping us beginners, I've learned a lot.

[RC3DFLYFREAK]

the dihedral on a wing allows you to turn by pushing the plane over, as the rudder yaws the aeroplane the taller part of the wing (Dihedral) is then facing into the wind pushing the taller part of the wing over almost like a roll.

Sam Bradley (BRADDERZ) or (RC3DLFYFREAK

[planesRus]

are you still diong that RC F35 VTOL or are you giving it up

[PenguinRCFlyer]

He's doing that it will be up tomorrow

[suvyMan2007]

he still is

[shakeythumbs]

keith is so funny in this ,you should dress him up as a cartoon dog or something ,and it would rock

[subocito]

agreed :D

[JoeFielding72]

This was a very informative video. I love how you covered so much. And explained that it does not take a thousand dollars to get the speed you need to do tricks versus buying the jet engine. You made my day. I hope you have the best Friday ever and I hope you have a weekend packed full of all the things you to do. God bless you all there and your families. This is the best RC Channel ever!

[M0t0rBreath89]

Awesome vid!! I hope the new schedule is as fun!

PS: I think you posted the wrong link on the description.

[Pirate88179]

I love all your videos....please keep it up.

Bill

[werrycoolnick]

great stuff keep the videos coming

[YupHio]

cool

[taofledermaus]

I'll miss the thursday shows. Thanks for another entertaining video.

[RacerLamboMurcie18]

no, i think he is going to intermediate now, but im pretty sure he will still have vids up on thurs

[StayStupider]

Looking forward to the new schedule! I've heard good things!

[4emu4e]

super ;)
