My CoroExtra 330 video

A little bit windy..video on my new found skill... doing low prop hang with coroExtra..like it very2 much..unfortunately my video recorder run out of juice so cannot take longer shot. Switch on and off that's why many2 shot cut here and there..
Enjoy...

CoroExtra 330

Introducing my CoroExtra330..

IMHO corrugated plastic is one of the best material for building profile airplane model to date. It's easy to get and cheap too. EPP is also one of the option but it's hard to get and quite expensive. coro is super tough and easy to shape. Although many people say that it's quite heavy compared to depron but I don't think so. A little trade off between durability and weight. I say go for coro dump depron. :D..

I was improved a lot since then with my coroExtra. Now I'm able to prop hang my extra very low until sweep the ground. No problem with crash since it can sustain crash without any problem.

some tips:

• All you need is a little bit of creativity and common sense while building a coro profile plane.
• Make sure when you cut your coro align to the corrugated line and it is perpendicular with your wing or fuselage.
  
• No hinge required. All you have to do is to cut it in half and make a clearance around 2mm fir easy movement of any flaps.
• Glue gun works like charm on coro. It's bind very good.
  
• Strengthen the wing by using carbon rod.
• See my second picture. Devise this extra body retention under the wing to provide additional strength.
• Important!!! move the elevator and rudder servos near the tail section for precise control. This is to avoid the pushrod from bending during servo travel. I get better elevator and rudder control. updates..
  

That's all..A little bit of imagination and creativity you'll get almost indestructible profile 3D plane. Later on I'll try to upload my video doing low prop hang with my charming extra..

My power plant:

• motor 1500kv
• prop 10x5
• ESC 30A
• lipo 2200mah 20C/1500mah 20C
• Servox3 Hxt
• rx ASSAN 6chn

With this setup I can do prop hang just in half throttle. Max amp draw from this setup is 22A. It's match made in heaven...

Well this kinna new interest for me. A drift car..just bought an entry level RC drift car from my supplier. Model name TC-03. I've modified the car so that it can run on lipo.

ASSAN 2.4 Radio system

I'm moving to 2.4GHz..good bye 35MHz..My Futaba 9CHP will be upgraded tonight. I just received my ASSAN 2.4GHz system today. Will put it to test this friday. Yeehaaaw..

It's great. I've installed the ASSAN tx module in my Futaba 9CHP and it's working like charm.
Some partial review.

1. The tx module fit nicely into my 9chp module. No moving part. The only problem is with the antenna. It is better if the antenna come out from inside the radio holder and also the antenna if you put your radio on the ground without any transmitter stand it will hit the ground. Also I need to modify my transmitter stand because the support part of my stand is in the way of the antenna. Need to lower the support part with some epoxy.
2. The binding process is just in a minute or two. Just switch your radio to PPM mode then switch back off and on again. Immediately move the elevator stick up and down several time until you can hear beeping sound and blinking red LED on the module start. The radio is waiting for binding signal. Put the binding plug on channel 1 and 3 then power up the receiver. In just 2-3 second the receiver LED will turn green. Then it's done. Just plug in all the servo into the desired channel and there you go. The system is up and running. It also comes with fail safe system on all channels.
3. Range test. I've tested around 100feet with blocking view such as car and tree. No problem at all. Will test more ground later on.
   

This 2.4GHz system works. I like very much. Some design issues but that's just minor.

Overall I'm very satisfied with it's performance and easy installation plus cheap 2.4 system. Good move assan.

F22 Coraptor

After looking at niezam coraptor my deep conscious of building plane is back online..hehe witness my new cororaptor. It's 90% from completion. Only took me 2 and half hour to print,cut and assembled this raptor. You can download the plan here http://rc.tomhe.net/f-22.
