KASAMA Srimok Electric Build Videos

Sounds like your using the Kontronic BEC for your servos?? What is the max amperage on the BEC? I think it is five amps, NOT enough with the 8717's. I am using Castle BEC Pro, It is voltage adjustable, and has TWO leads to bring to the receiver. I use this setup on two VBar Machines and never had a problem. I use a 3s 2200 Mah lipo battery with the Castel BEC Pro. Love that setup!

I think you're right - I run two leads from the KT BEC which is rated at 5A but I guess is lacking when the disc is loaded up in FFF or hard 3D - I want to look into this a bit more so will do some FDR first with the existing system and get a feel for normal servo current draw - on a nitro FB 90 this is ~2.3A but I guess FBL and with JR this is gonna be more - I think I'm gonna give the Fromeco Kiwi a go !

Look at the stats on this bad boy!

I fly MKS 767HV cyclics and BLS980 on unregulated LiFe 6.6 V bypassing my JIVE 80+HV. Works great and very simple.

Nice simple setup Henrik - elegant - only problem is that A123 can't deliver the same current as a lipo or LiIon and I have heard a few reports of brown out with that system under high load especially with JR servos as they are current hungry - not sure about the MKS - I am using the 980 on my Joker and it seems great - Kasama uses the Jive BEC with NiCd 4 pack in parallel

Mercuriell, I see your using the KT 120+HV which is what I'm using too but do you know how to change the headspeed in gov mode.

I have it set in that and set it in APM as standard so would this mean if I have my throttle curve in normal mode set from 0 - 80% would this be recognised as 100% in the APM mode?

When changing the throttle curve in idle up it does not seem to change headspeed?

Cant understand the manual correctly and I'm not the cleverest when it comes to bits like this so any help (if that lot makes sense) would help me a lot

Cheers

APM Mode 1 is not recommended for helis as it isn't governed - all you need to do with the JIve is start off in Mode 1 which resets everything - then set in Mode 11 (assuming you have Series 7 firmware which you should in a 120) then just check for direction of rotation and if incorrect just swap two motor connector and you're set !

Program your throttle curves straight line in normal and flat in idle 1 - 2 - around 80% flat is the sweet spot for the Jive but anywhere 60-90% is acceptable.

The Jive spool up is very soft so it is also possible to have your normal curve 0-60-60-60-60 if you want to avoid trying inverted flight while chopping the power

I got mixed up, I have it set in mode 4, but cant see any difference between 4 and 11.

But will set for mode 11 and see what that does

Thanks for that, will do it ready for the weekend

[Littlewing]

Sweet !

This will be my next build,the quality is outstanding.

I don't usually watch 3d flying but ...

is brilliant, that sound !! OMG !!

Thanks for the heads-up on this heli.

Regards . Dave.

OMG! I have to tell you..... There is nothing better than flying BIG! That is so freakin impressive to watch vs stick banging. Why dont more people fly big?

[gothicbunny]

Was he trying to skid to a stop in the circle at the end of the auto or did it just work out that way?

I guess he just got lucky

Would love to fly big BUT in my case it is just too expensive!

[dolcevita]

its great helicopter....

Has anyone ended up with a damaged 6S lipo on this Srimok FAIFA? That's the only thing holding me back on this model: the nose-mounted lipos configuration is just asking for major lipo damage in the event of a crash...

[Mercuriell]

The lipo is no more vulnerable on the Faifa than many other helis, if you smash it hard enough to damage that you're going to have a lot more to worry about than the lipo!

[Lorbeer]

You're making sense there Mercuriell ;-) Many thanks!

[hookmaker]

Lorbeer, I can tell you that a pilot here crashed his FAIFA 2 weeks ago. He drove it nose-in into the ground. Both frames broke (+ some other stuff of course) but both batteries suffered not a scratch.

[Lorbeer]

And I have in turn heard of in-tray battery mounting helis damaging lipos in a crash. So yea, you guys have a point, the lipo can be the least of my concerns in a crash. Been dreaming of a Srimok 90N since I was newbie, now that I gave up nitros, I'm setting my eyes on the FAIFA. So uh, just an honest question for all you Srimok guys, does it fly that much different from the usual field of 90E's?

Well I've only flown the TDR, Minicopter Joker and Diabolo but I have to say YES. In common with all the Srimok frames they are very efficient and make very good use of power - the FAifa is very agile (lipo CG up high) on cyclic and is also very fast using reasonable motors and packs - I have a beat up old Pyro-30-32 on mine and use old packs and it still flies phenomenally ! It won't strip main gears though you do have to setup the crown gear carefully and re-adjust after a few flights - then you're set to have dozens (hundreds?) of flights without maintenace other than the occasional oil.
