New Avios Mig 17 ?

[RanGee]

What's the recommendation for the timer using a 5000mah battery, for mixed-throttle use? Should I set it for 3.5 mins?

It looks to me like longer times might be OK since this model doesn't need full throttle all the time.

The Mig's stock power system is very efficient, you should be okay with 4-5 minutes of mixed throttle. I flow mine (mixed throttle) for 4 1/2 minutes and landed with 43%

Assembly completed. Some minor issues easy to fix but they could have saved me about an hour of fiddling with the inner gear doors by putting one line of instructions in the manual. Added pilot from crashed Mig 21. I decided the flimsy foam tail skid might last about one flight so a friend 3D printed me up a new one. The lightburner kit was an easy install and looks great. The hardest part was routing the wire. Balanced on the indicated CG with the battery all the way fwd plus 2.5oz wt. Maiden maybe Fri?

Any chance the stl files for the skid can be made public? Thingiverse has lots of useful things and this would be a welcome addition.

Thanks

The tail skid looks awesome, great idea!

I have some of them too. I agree with the cost but I can afford them and think they are worth the price. Yes for a sale price and you can email him and he'll send you a coupon code for $5 (or more) and he has free shipping over $50. Good other products too.

My preference... I have a dozen and use them in 70-90mm 6S and 80-90mm 8S with a 2 cell. Love them and they are small and light.

They make some good stuff!! I wait for sales to get them though since the prices are pretty high. But man.... they are a dang good battery! I have some of the 6s 50c 6200mah and they are awesome!

For anyone who's looking to change the servos on his Mig, I found this servo to be a perfect fit.

Hey guys check these out. Choose your flavor in 40c or 65c. I have both and was blown away by their performance! the price is amazing too! I plan on using the 40c in mine when its ready to go.

Here’s a maiden with some commentary......

Yes, I got most of them when they were on sale for $55

that is a great deal.

[RanGee]

i have noticed the dip in performance at higher cycles on the CHNL's

so these are the ones you are talking about? price is great!

Yes, I like the heavy-duty much more than the CHL; the CHL seemed to lose their punch after about 20 cycles while the heavy-duty ones are still going strong after about 70 cycles

Ran, you like these turnigy lipos? gonna have to give them a try. I fear the graphenes will be too heavy but they do pack a punch like the china hobbyline G+ series im using.
I need to save money so going to be putting the 3s packs in series 4000mah 55C G+ china hobbyline packs in to circulation. The smaller capacity should give about 3 mins of pretty good punches here and there as this is a lower amp draw setup.

Mine (using the turnigy heavy duty 5000 6S) is tacked all the way to the back up to the junction box to achieve the recommended CG

Still have mine on the bench but trying to get it ready for NMAD. Needs a clear glossy coat to give it the shine and maybe some flight metal on the inlet. Got a spare 9 channel AS3X to install but from what videos I have seen looks smooth without one. Looks like the overall is that's is a nice plane. In regards to HSD building this, does not HK use AF Models for their planes? Perhaps they both have the same suppliers on pieces

Hey wolpertinger,

I wouldnt waste an as3x module on this one, shes a floater and a trainer with a 90mm edf...essentially is what this is. This thing flies easy, and slow, and does not dip at all even when going really slow...my second flight (sorry no video) i was able to slow it down to a stand still in some head wind...kind of like flying a kite. moving the CG back will help with this evemore more so.

I am not too familiar about the suppliers HK is choosing, they dont seem to be operating the same way a few years ago so i wont chime in as my assumptions may be misleading. however i strongly feel HSD is the main supplier because if you just look at the mechanical footprints of this jet, its got HSD written all over it. Also if you search the edf and motor on google, its HSD... so... that is why i think what i think.

I wish you the best of luck and tons of fun for NMAD.
just hollar out if you need additional intel with this bird

[tengarang]

Nice flight dude!

thank you sir i appreciate you shipping the lightburner kit so quickly. just in time for the weekend festivities with the rest of the guys....

Maiden Flight went well, had to give it some up elevator, as forward CG position required some up elevator trim set. Dont like it sitting at netural with deflection up so i am showing all of you where i will be putting my battery the next flight which should allow me to set my elevator trims at dead center.


Tengarang, what is your measured CG position? Are you on, before or after the book cg position? Curious as batteries vary in weight.

oh yea, nice vid of the flight....👍

thank you sir.

you have a very good point

please see the attached picture of my relative CG location compared to the manual. I am slightly behind the cg stated on the manual. I also think moving it further back 3mm to 5mm will even help flaring much easier as well on final approach.

i balanced with the aircraft up side down. and there should be a few degrees of nose down incidence to be accurate from what i see on my side when balancing up side down
