Zoom Tips and Tricks

[rob_jones]

Let's see if we can start a thread dedicated to Zoom/Shogun tips and tricks. If you've found a solution to an aggravating problem, or have a new modification to share, post it here.

I'll get things started: If you are using a 20mm brushless motor (Himaxx, 2025, Hacker B20, Chili Pepper) you have doubtless discovered the need for a heat sink. I searched high and low and couldn't find anybody who had a 20mm heat sink in stock. I finally found one with a company in Japan (Air Craft - World). It is made by Hacker and inexpensive ($9.80). Shipping from Japan was only $2.50 (!) and I had it in 5 days. Here is the info if you want to order one:

You can also email them at shop@aircraft-world.com

Be advised, it is a VERY tight fit (at least for the Himaxx). I had to remove the label from the motor and carefully pry the heat sink open with some blocks of wood and a screwdriver. I haven't taken any scientific measurements, but it's a lot cooler to the touch. So it must work! :mrgreen:

Tip #2, the stock hex tail rotor shaft is junk, will bend if you look at it wrong. Quick and cheap fix is to go to your local bike shop and ask for a 14 guage stainless steel spoke. Mine cost $1.09 and has enough materieal for a few tail shafts.

The SS shaft runs much truer and helps eliminate vibes from the tail.

Tip #3 Use thick CA on all the wood type screws, dont want them falling out (washout base etc).

Tip #4, the stcok pin on the tail rotor pitch slider will fall out, best to take it out from the begining and thick CA it in so you dont have to worry about it.

Tip #5 Main gear rubs the frame, mark the 4 points where it goes throught the frame and grab a drill bit and drill a hole in that area to make clearance for the gear. You can also just use the x-acto a bit.

Tip #6 Either use a heat gun or Boil the stock landing gear and spread them to get a wider footprint, very useful for autos

I will think of some more later

Good tips. I never thought of the bike spoke. I like that one!

There is also a wider landing gear available if you don't want to try bending them. I've had them for a while and they seem pretty tough. And they sure look better!

[WillJames]

Thanks for the tips. Ordered a heat sink for my Chile Pepper. Where is the wider gear from?

Thanks again for the tips!!!

If you spread the stock landing gear apart for a wider stance, isnt the tail more likely to hit the ground during landings?

[rob_jones]

Ok, so far this is the only source I've been able to find for the wider stance landing gear. This company is in Hong Kong. When I ordered mine, a group of us from Ezone placed an order together to save on shipping.

I'm still going to try to find a better source. If I can, I'll let you know.

What parts do I need to keep on hand for my Shogun??? Crash and otherwise?

[rob_jones]

I would, at the very least, have these items on hand:

165188 Tail Rotor Input Gear - they come 2 to a pack
165190 Tail Output Shaft Set - the hex shaft that the tail rotor spins on, includes plastic gear
165196 Main Drive Gear - I haven't stripped one yet, but I'm sure I will
165128 Tail Pitch Control Lever
165160 Hardened Main Shaft
165144 Spindle - although a 3Mx45 bolts works great here. A 4-pack is $1.30
165148 Tail Boom
165150 Tail Boom Support Braces
165162 Tail Rotor Drive Shaft
165180 Main Rotor Blades

I know that's kind of a long list, but unless you really pile it in, you ought to be able to keep flying without waiting for parts.

[Hotshot Charlie]

Whew, but it looks to be a very complete list. Thanks for the trouble you went to to make up the list. Guess I will start ordering some now, I know I will need them... hehehe :mrgreen:

[rob_jones]

it's no trouble! :mrgreen: I already had the list ready. You can order all of those parts from Hodges Hobbies. I know this because that's the same list I gave him.

[rob_jones]

Updated list with prices:

165188 - Tail Rotor Input Gear 5.99
165190 - Tail Output Shaft Set 6.99
165196 - Main Drive Gear 10.99
165128 - Tail Pitch Control Lever 4.99
165160 - Hardened Main Shaft 12.99
165144 - Spindle 5.00
165148 - Tail Boom 9.99
165150 - Tail Boom Support Braces 5.99
165162 - Tail Rotor Drive Shaft 6.99
165180 - Main Rotor Blades 28.99

These prices are from Hodges Hobbies, but they are the same pretty much anywhere. He doesn't have them on his web site yet, but you can call or email Mac and he'll hook you up.

Well since my Tips and Tricks thread is officially dead and not sticky, I'll post this here so other people might benefit from it.

Pin your tail case to the tail boom with a screw

Mine exited off the end of my tailboom today( I had CA'd it ) providing an unexpected upgrade opportunity for my Shogun Ever see those videos of 60's or 90's that loose their tail rotor? It was sort of like that but the piro rate was much higher.

Battery, Blades, Flybar, Mainshaft, Feathering Shaft, Blade Grips, Frame (ears broke off for landing gear, time for those CF adapter plates ).

[WillJames]

OUCH!! Sorry to hear that Sar.

At least it is an upgrade op.

[Hotshot Charlie]

My Shogun is here, arrived this afternoon !!! Neat little heli, can't wait to fly it, but I have a lot of stuff to buy first. I think I might have to give it a run with the standard motor first, then add a brushless setup with the belt driven tail upgrade. I just want to see this baby fly !!! :glasses:

WhaaaaHoooo !!!

[Hotshot Charlie]

Sar, it sounds like I need to drill and tap my tailcase to the boom !!! Thanks for the advise !

[ScotY]

I would suggest not only the tail gear box, but also the boom clamp in the frame. Ask me how I know this? :mrgreen:

[rob_jones]

Ask me how I know this?

Don't need to! :wink: Been there. Done that.

This reminds me of another trick. I had a lot of trouble with the tail boom not staying in place (twisting and sliding out, which screws up the gear mesh). I put a small piece of self-stick sandpaper on the inside of the boom clamp. That seems to grip the boom much better and keep it from moving around. I also cut two plates out of some carbon fiber (lite ply will work just as well) that sit on top of the boom clamp where the screws go through. They act as stiffeners on the clamp and also help to keep it tight.

Landing struts tip:

I turned the stock rear struts around so they slant to the back. This ideally shifts the skids further back under main mast, giving the heli a better foot hold and less chance of a tail bump.
asthetically it gives an illusion of wider stance too.
