I don't crash like I used to.. so 1 pair lasts me these days though..



Would this American supplier be able to ship over the pond to the UK, in a manner thats not too expensive? Nudge nudge wink wink

know what I mean, know what I mean.

Well.. he could but your in a better position to buy from that other place.
I assume your time to get the items would be about the same from both places..

Very nice, kt74.

Here's mine flying in my garage (poor pic quality). After several mishaps with BL motors, finally, it's in the air. I'll post some pictures and spec of the new bird tonight. Enjoy.

ps. Thanks Jon for the help on using the HBFP main gear. It works perfectly.

Looks real sweet!

BTW, I compared the spin-down time relative to two arc 130s I have on DD tail set ups and mine take about 5 seconds I'd say, compared to yours 2-3 secs I estimate; therefore your tail (assuming pinion is not overtight!) is impacting that noticably IMO.

Curious, how hot does the motor get and do you use a heat sink?

Have you tried some silicone shock oil on the belt to see if that helps? It might ease some belt tension.

Lastly, on the right piro / deflections does it make sense to go with a diff servo horn to try to get max deflection (if I understand your current set up?)

I was wondering also if it makes sense to try diff tail blades. Not sure if these are too large or not but might be more fruitful than trying to get a new tail shaft w fewer teeth?? I have yellow on one of my trexes. They are pretty good from what I can tell, and they indeed add to visibility.

Love that ARC 130. From what I can tell from your movie, you could have a rocket on your hands. I suppose you could take it down a tooth or two to extend flight time and/or ease up on the motor? Im guessing too you could handle larger lipos with ease. How are punchouts? Nuts?

BTW i do apologize about asking the spec...you clearly already posted the details with the vid....im such a 'tard

nice vid , whto

we have the same garage door !!! or during the winter i call mine the heli magnet

is the ESKY 3800kv motor usable on the compy ? would save me from buying another motor

The deflection is limited by the pitch slider, not the servo horn. Short of playing with the length of the tail pitch links I don't know how this could be fixed.

I'm using an Esky 3100 on my Compy with the supplied 9T pinion, and it seems fine (doesn't get hot, 10 minute flight time on 1250mA 3S.) The 3800 might be a little overpowered but it might be OK.

Thanks. Same here. Lot's of "scars" on the door.

As ccdengr says, the 3800kv might be a bit too strong.

I'm running ARC 130, as kt74 has, together with with 8T pinion and 1000mA 2S. Filight time is about 9-10min. The motor get a bit hot with heat sink, but it's still cooler that the Slo-max on my HBFP.

It seems, maybe I misinterpret, that kt74 has the servo thro at 50% therefore I was assuming perhaps he wasnt getting max deflection (so as not to get servo buzzing).. On the pinon issue, I was thinking that on an ARC130, if you are lifting off at 40% thrott with that motor, that indicates typically you should go down a tooth or two, which has some other benefits, if you get my drift. With flatbottoms and a 130, on my dragonflys, I was lifting at about 40%, so I dropped two teeth making it more controllable and less strain on motor -- thus my questions. It all a balancing act as Im sure you know. I love to see a nice FP machine. I really like what I see..

Yeah, my belt is a little too tight. I haven't tried any silicone spray or anything on it yet. I am using a heatsink on my -130. After hovering for about 10 mins its almost too hot to hold. How about your -130... does it get hot too? But I still haven't even gotten close to using up 80% of my 1300mAh LiPo's.
I put my Belt-CP tail blades on the Compy to see if they would make a difference. That's what you saw in the video. The tail holds really solid in flight and during punchouts. But the CW piro rate is just slow. The motor is really powerful and I don't think I've even hit half-stick with it yet.

Well if your motor is really hot like that, you may want to change the set up some. (how is the batt, hot?)

Mine (Motor and batt) is cool to warm usually, but not HOT. If you drop a pinion tooth or two, each turn of the motor shaft will intersect fewer main gear teeth. You would thus be going to a higher gear ratio, which means more torque (thrott control), and less headspeed (which you dont need), and thats easier on the motor and batt -- if these are the blades you'll use.

With a belt tail, you want Im guessing to get good tail performance so I would work on that. Its not going to be like a trex, but just the same, i"d want better than motor driven. (The piro rate on my trexes is insane -- its spins round in a split second). Im just curious if your tail slider getting max deflection on the slider or not, Im not clear on that.
Again, looks like its going to be really terrific.

The battery isn't any hotter after the flight than it was before. It's a 20C pack so it can handle the motor no problem. I'm using an 8T pinion which should already be helping the motor out a bunch.
I am getting full deflection on tail slider... so that doesn't seem to be the problem. I have the 0704A HH gyro that I think I should try on the Compy. Maybe the rate gyro is having issues. I don't think so though because it did fine on my Belt-CP.
Other than the piro rate it flies really well. I think if I had to live with the piro rate I would still love the heck outta this little bird!
