Hey guys, I just unpacked my new Zoom! I bought the Heliproz package with the Himaxx 2025-4200 & CC Pheonix 25. I want to know what mods you guys think are MANDATORY before first flight. I will start with the stock brushed motor and install the Himaxx later.

I figured (from reading here) that I need to at least CA in the pitch slider pin for the tail rotor.

What else NEEDS to be done?

Thanks.

I always use a dab of thin CA on the Brass gear that is on the Carbon tail drive shaft. I have had that thing give loose once or twice on a new kit.
Besides that and the pin that you mentioned you should be good to go..

make sure the gear mesh is good on all gears. make sure the pinion gear on the tail shaft does not hit the output shaft sleeve. i would put some glue around the tail case where it contacts the boom and also at the bracket that mounts the boom to the frame. sometimes they will twist or spin. some people have pined the tail to the boom but i found that glue works just fine. have you decided on servos, gyro, battery and where you will be mounting everything? you might also need a battery tray or extension. If the rubbing is bad, you might need to trim a little bit of the frame where it hits the main gear.

I made a battery ext shelf out of 1/8th balsa covered with monocote adhesive paper, stuck it with servo tape, then velcro'd battery to it flat and forward, even moved gyro to the front and receiver under it just to get it to balance with the stock motor. A carbon fiber rod for the tail really helps, lots of rubbing in the stock rod, if you have a piece of 3mm rod you can wrap thread around small wire pieces on each end, CA it, and then you can use the Dubro mini ez connectors on tail lever and servo arm. If you want a cheap tail servo mount, use the zip tie bases at Home Depot (1.46 for pack of 8) or two of the stock plastic boom and tail fin mounts turned upsidedown to form a shelf for the servo (battey is a Kokam 1500 lipo)

But you will need a brushed controller to run the stock motor. CC P-25 ESC won't run it. If you already know this, then ignore what I say. I am just assuming you may not know.

Stuff

I will be using three HS-56s and an HS-50, a Futaba 401, and an Electron 6 RX. I already bought the zip tie mount for the gyro (but I got it at Lowes). The Kokam 1500s seem to fit just fine on the intended battery mount up front, but I do not yet have all of the radio gear so the CG might demand I move it forward. Is that usually the case?

What is the best way to know if the gear mesh is what you want it to be? What is too tight and what is too loose?

I already bought most of what I will need to do the cheap belt drive forthe tail.

Thanks.

Thanks iskoos. I already had a brushed ESC. About the only non-glow and non-turbine thing I own.

Are the blades to be expected to be pre-balanced? Or must I futz with them? They do not feel weighted so I guess auto are a no-no at this time, right?

Thanks.

The like 90 blades fly nice and are not too $$, OH and if you havent heard, heat up the White plastic struts to bend your landing gear wider, will really help prevent tip-overs. A heat gun or take em off and put them in boiling water to soften em up, try to bend em at the elbow so it doesnt bow the top, and about a 2 paper thick gap for gear mesh is close

Stock blades are ready to go they are balanced but you may need to tinker with tracking. And yes NO autos. Don't ever try with stock blades. I tried once it was no different than a free fall.
