Good to see you guys having fun!

[@RCVideoReviews]

Thank you :)

[@toddkoffler5681]

It’s so nice to see him absolutely loving his new plane!

[@RCVideoReviews]

He waited a long time for this one. I'm glad he has it.

[@toddkoffler5681]

@@RCVideoReviews that’s awesome!

[@davidpaker626]

😁

[@williamcox3852]

Very nice Dave. I envy your style of flying. Makes me wish I was 20 years younger. Keep up the good work guys.

[@davidpaker626]

🙂 Thank you very much I appreciate the nice comment have a good one.

[@RCVideoReviews]

Thank you Mr. Bill. Thanks for watching and checking in.

[@davidpaker626]

Yes, what a nice beautiful Flying Machine. This airplane Is probably my favorite airplane right now. As much as I like flying my pattern planes. The 60 size 3D planes are very Nice very good flyers but this is next level. It's on a whole different category. But this is just my opinion as a good sport pilot with several decades in the hobby. Oh, and by the way, I need to correct the weight of the airplane. The scale was set to pounds and ounces so it's actually 14 pounds 8 ounces Or 14.5 pounds. Oh, and last but not least, John and the channel Made some Generous contributions To the Dave's 78" extra project , 7 years + or - in the making. put it in the car, taken it out of the car, Put it in the car, taken it out of the car. Prudy awesome thank you.👍🙂

[@RCVideoReviews]

Glad to give back Dave. You've been a wonderful addition to the RCVR crew and I know all of the people who watch the channel benefit from your love of the hobby. I hope we can fly these planes together for a long time to come.

[@davidpaker626]

👍🙂

[@simonsutherland814]

Ripper, model and flight 👌🏻

[@davidpaker626]

Thank you

[@Phuong.Nguyen-]

Good footage ❤😊

[@RCVideoReviews]

Thanks! 😊

[@davidpaker626]

👍🙂

[@Retset]

Awesome flying of an awesome model Dave!

[@RCVideoReviews]

Agreed! Nice job.

[@davidpaker626]

Thank you very much , appreciate the common 😎😁

[@rcrotorfreak]

Wow I bought two Futaba 8fg at the past from Tower Hobbies then the Futaba 14 sg. Futaba alway's been very great radio. I alway's loved Futaba over Spektrum. I used Futaba very long time. I had bought at the past even the fm radio of Futaba.

[@davidpaker626]

I've been flying futaba for 40 years plus never had an issue. I like it. For the new generation everything considered I can see the radio master radios being a very good option. I'll just have both.😂

[@AngelVenkov1]

Hi RC Video Reviews, Again amazing review. How many KV is the motor? Thanks Angel

[@RCVideoReviews]

That's a 215Kv motor.

[@SlowFlyer85]

Nice looking model and great flying 😊👍👍

[@davidpaker626]

🙂

[@FelipeCerdaBarra]

Dave really needs a mah sensor

[@davidpaker626]

I copied the program from the vanquish, adjusted everything I needed to for this airplane and totally Missed doing my flight time calculations To come up with a flight time. This is the first time This happens to me, but there's always a first time. 😁 Telemetry on your voltage level is definitely good. It's like the gas gauge on your car.

[@FelipeCerdaBarra]

@@davidpaker626 yep! Nothing like having telemetry for voltage or consumed mah for these not so cheap airplanes

[@L..E01]

How many amps does the motor draw?

[@davidpaker626]

Hello, it draws 110 amps +or-. somewhere after the midpoint of the video we ran the Apps, wattage and voltage drop test. You probably missed it when you saw the video. Check it out. Have a good one.

[@old-rcplane-phart]

Just so I'm clear, running a rx battery on the big planes?

[@davidpaker626]

Hello, the opto ESCs do not provide power to the receiver, they do not have a battery eliminator circuit BEC . So you have to provide your own power to the receiver via an external BEC , regulator or a receiver battery. On a separate note, I like to have redundant power supplies for my receivers. So I use 2 batteries on the opto ESE's. and on the regular ESCs I use one battery with a diode and the BEC that is supplied by the ESC Also with a diode So they can't feed each other power to avoid damage, Also, the diodes dropped the voltage of the 2 s life Batteries from 6.6 to 6 volts Which is better for the 6 volts rated Servos. I hope I understood the question correctly I took the answer just a little further. But the information is pertinent to the question. I hope I understood what you were asking and this helps. have a good one.

[@RCVideoReviews]

For my big planes, I want them to get the max voltage to the servos. So I use a 2s battery which gives me 8.4v to the servos. Of course the Rx has to tolerate this. Using an external battery also improves the reliability of the system overall because you're completely removing all (imperfect) electrical elements from a BEC from the equation. In other words, it greatly simplifies power delivery--fewer parts to break. So the upsides: - More reliable. - More power (usually--some BECs can deliver higher voltages). - In Dave's case: redundancy. I cover how to wire it here: kzbin.info/www/bejne/r6DalJ2tmryel7M

[@slange455]

Wow can’t believe you guys leave your planes on the table like that …must have them secured to the table

[@davidpaker626]

Yes, the airplanes are secure to the tables. We had to come up with a way to anchor them down. Because we fly even on very windy days and they will get blown off the tables. I think John shows the anchors on one of the pilot jams. If you are interested in them , let us know, we'll figure out a way to show you how to make them have a good One.

[@RCVideoReviews]

100% Dave came up with a neat little tie-down disc system and I've been printing and giving them away for at least a year now.

[@slange455]

A lot of the better pilots don’t use dual rates ….I usually set them up but then just use high rates with a good amount of expo

[@crashalexander7232]

many do and multiple flight modes as well ....all about what works for you.

[@davidpaker626]

Yeah, the truth is, the 3D planes are usually flown all the time on high rates very high expose. The other 2 rates is just An old timers habit , A very long time doing it, hard to get away from it whether I use them or not 😁😁. If I only flew 3D airplanes i would probably force myself to only use high rates all the time. That would be the way to go I agree.

[@RCVideoReviews]

I'm starting the migration to high rates only on these planes. I think on the 67" Laser after the maiden I switched elevator from 70 to 75% and I'm pretty happy with that.

[@mithrandir1313]

15 pounds!!!??? Wow… heavier than expected to me… seems to fly good though!

[@RCVideoReviews]

They fly fantastic.

[@B0767]

Nice video…. However some really bullshit of Dave in the beginning….everyone with some knowledge of electrical motors knows that voltage determines speed and current torque. He pretends that HV servo deliver more torque 😱 no they are primarely faster!!!

[@davidpaker626]

Excuse me, I do not b*******t. I do this just for the Information and entertainment of people. And I guess you don't know as much as you think You do because speed does translate to torque when you gear it properly. and we're not talking about A motor only, we are talking about a servo. Also a lot of these motors On servos these days Are three phase motors motors and the correct way to increase the speed on a three phase motor is increasing the frequency , not the voltage .And you are very welcome for the video. And by the way, like I say. I do not b******* if I have some information incorrect or a wrong concept It's not b*******,

[@RCVideoReviews]

You’re completely incorrect about what hv “primarily” delivers. Higher voltage servos deliver BOTH increased speed AND torque. In fact, I believe (without confirming the math) the percentage increase in torque is greater than the percentage increase in speed as voltage increases. Every servo spec sheet I’ve ever read shows an increase in torque and speed with increased voltage.

[@RCVideoReviews]

Also, we don’t talk to each other like that on my channel. If you can’t maintain a cordial and polite conversational tone, you can go somewhere else.
