definite coolness! :aok now i have to go get one of them for my ponyD

however........he gets 0 points on that first landing, and very low points on the second one. he missed the flare both times. :noid

The cool thing about this sound system is somehow its hooked to throttle channel.
 When he gives it throttle the motor revs higher. Never seen that before.

I ordered the LeRhone system for my Fokker Dr1 and was saving it as a surprise for you guys.  :frown:

so how does it work? is it electric angine or gas?  does he just have some adjustable merlin engine sound track thats played thru some little speakers?

i noticed he flew it on a 4 blaede prop. most only fly on 2 bladed props. wondering what he has for an engine in it myself

I avoided the problem of adding a sound system to my R/C P-51 by installing a 4-stroke engine from the beginning.  It doubled the build cost and the plane came out a touch on the heavy side as a result, but it's been worth it I think.  It flew very nice up at altitude when I built/flew it at the USAF Academy so I am hoping I'll get a chance to refurbish it after 3 moves and fly it closer to sea level.

its an electric engine. I use to work on rc planes and cars, trust me if it was nitro you would know it.

and its just a recorded sound track played from the nose cone, connected somewhere between the motor and receiver. 

and that plane is waaay to nose heavy.

if you're saying that from thew taxi or from the landing, every mustang i've seen taxis like that on grass, including mine, and mine is not nose heavy.

 as for the landing, it seemed there was a crosswind, and he just got caught up in correcting for that, and forgot to flare.....twice.

something i just remembered.....i thought there was a post on these bbs, awhile back about a miniture allison or merlin....that ran.........that'd make more sense. i've never seen an electric powered rc fly on a 4 blade prop.....

in fact......whatcha think about this??

Really what you need to do is to contract that guy that built the exact scaled down version of the Ferrari to just build a miniature Merlin engine LOL

but that was a col clip.
thanks

That was pretty sweet.  Makes me want to go out and by one.  Although it would probably be a bad investment with my flying skills!!   :rofl :lol

would be cool as hell, wouldn't it? :D i'd FIND a way to afford one for my pony.

For one I can guarantee you that the p51 is electric. And he needs to go back to his kadet senior for the landings lol. cool video :aok I looked up that module that the guy with the poney used, its a lot more than I thought it would be, bout $300.

Well sir, than you have never seen my poney taxi/land  :D

It takes a much better system to work over the noise of nitro or gas but it can be done.

The dead giveaway on electric power was the nose over on the first landing I guess you missed that?

The dead give away was from the start. The speaker on the plane is in the nose cone, in-cowl muffler and for that matter no muffler would have enough room and you can see there is no pits muffler. And nitro doesnt just start ya gotta have a starter, you dont just put the throttle forward and it starts.

Actually you can. I have a P51 Christen Eagle and F16 (jet) that have auto starters on board. I mean its obvious to someone that does electric from the cooling holes and odd lines for a scale plane but not everyone is going to pick up on that.

Zenoah G62 for the P51 and Eagle and the F16 uses the Wren XL200 with autostart and FADEC controller modifications (about $4000).

ohhh gas and turbine... nice motors btw. thought you meant nitro auto starters.  was confused

i believe they make remote starters. one of our local pilots had em on his pattern ships.

i've also seen a couple companies that offer scale exhaust. they actually build exhaust stacks to come out in the proper place, and if that was a gas engine we wouldn't see exhaust. if it were nitro, we would've.

 i did notice the restart though after he nosed it over. that would lead towards electric, but i've still not seen an electric that could fly on a 4 blade prop before.........

 i still like mine with the ys 4 stroke in it. she flys beautifully. fast, short or scale takeoffs, and nice gentle landings.
