How much and where are you?

Can somebody please tell me how much the stock esc weighs? I gave mine to a friend and can't recall the weight. I want to use an 80 amp hobbywing esc, it weighs 77 grams, has 4 amp switching bec and 120 amp burst rating and the price is affordable. They also have 60 amp and 100 amp versions if anybody is interested, more info here www.hobbywing.com

Hey slowfly, where did you get your Hyperion motor?

I bought mine from national hobbies in mesa Arizona, I heard they just went out of business though. They sold mainly heli stuff, I guess that hyperion as well as the 3026-1000 are good motors for 450 size heli's so they happen to have it in stock. I've been thinking about doing a 3s yak here soon, make it as light as possible. The 80 amp hobbywing pro esc looks good with the hyperion motor, only 11 grams gain in weight. The motor is around $75, the esc is around $55.

I was looking at the airtronics 94761Z servo, it looks like the best servo available for the yak. It has the same dimensions as the stock servo except the airtronics uses dual mounting hole tabs. I use hitec 5085 which are rated at 50/60 ounces of torque, speed is .17/.13 and weighs 22 grams. The airtronics is 55/66 ounces of torque and .15/.12 speed and weigh 23 grams. The airtronics looks to be the fastest and strongest servo for the yak I could find.

I bought mine at Allerc.com also. They incorrectly sent me the backmount version ZS3025B-08 but the same day I sent them an email about the mistake they shipped the correct ZS3025-08 together with a prepaid UPS label for me to return the B-version to them. Good service.

I found that the collet adapter that comes with the Hyperion is a bit too short for APC E props (the nut tightens on, but just barely), but the HP-ADAP-50L HYPERION LONG 5.0mm COLLET ADAPTER M6 (EP) I also ordered for $5 works well. Neither Hyperion collet will let you use the spinner, and props reamed for the stock Yak collet won't fit on the thin M6 shaft. On the positive side, you don't have to ream new APC E props to fit on the M6 shafts, just push in one of the plastic APC hub adapters and ream the inside of it ever so slightly. I might try ordering the HP-AD-850XXL Hyperion Extra Long Prop Adapter - 5mm for $9 from rcdude.com -- it has a length of 48mm vs the stock length of 45-46mm and I believe would allow installation of the spinner. Of course then you're back to the same M8 shaft as the stock adapter which you could just order from Horizon (with another set of motor mount screws - these get stripped easily).

I found that the stock adapter was quite soft: it bent easily and the threads got mushed up after a few prop changes. For now I'm without a spinner and hoping that not having it doesn't cause reduced airflow/cooling/motor temp issues.

So im guessing yours is the H motor. The zs3035 is $125!

The spinner is actually not good for airflow. You will get better cooling without something blocking the air hole

I am using the ZS3025-8, it's 970Kv, weighs 197.6g. The 3026-1000 is 1000Kv and I believe weighs the same as zs3025-8. I'm guessing the 3035 is too big for the yak.

I forgot about the hyperion adapter, it is a tad short. I use a precision aerobatics 5mm prop adapter and a pa carbon fiber spinner, works great!
