Heng Long smoke units..problem solved!

[Saxondog]

If you have been to the post yellowshaker has posted and read through the last two pages we have outlined the KEVLAR wicks and the type of resistors that work best as the heating element.Normand ran his for 15hours before element failure then changed to a better type of resistor with kevlar element and this unit is still running.I will be posting the design here next week when Dan returns home and we agree on either producing these units for sale or posting the assembly instructions.That being said I commend your work and the resourcefull way you aqiured the parts.You can purchase the Kevlar material and the link is posted on the link yellowshaker has given.DanL also listed the type of fluid that works so much better,the exhuast exits the tank and drifts down insted or up.The next thing we are trying to perfect is colored smoke.Also we have had a lot of fun designing the smoker as our intent was to have a design that can be built for several scales and model types,we would welcome you input as you seem to have some good idea's.Hopefully we can all benefit from the results of everyone's efforts as their has never been a reliable smoker design that is dependable.The resistor and the Kevlar wick is the key to long smoker life.Good luck with you design,Blake 1-saxondog

I was mistaken the post by yellowshaker has some of the same guys,strumn54 is Normand and a right smart fellow I might add,also Danl graphic designs are perfect and very detailed.This is another link to a posting where the smoker designs were tested and the best resistors are listed by type and ohms. http://www.rcgroups.com/forums/showthread.php?t=1182927" onclick="window.open(this.href);return false; hope this helps as the testing is outlined on page 4 and 5.

Hello Blake, :~
I would just like to add a small part to this excellent set of threads on the smoke makers. :~
I have been searching on Ebay to find Kevlar material but could only find 1 item and that was of 6mm Kevlar string used for 'fire-juggling' so I thought that it might work, but from the linked threads it seems to be much better to cover all the resistor,to spread out the heat more evenly and get more smoke, so I needed something a bit wider.
I could find 10 mm wide glass-fibre wicks....so I just checked on the internet to compare the two materials,
( Kevlar -V- Glass Fibre..... with a surprising result
Kevlar.......... no melting , degradation starts from 500°C ( At 260°C a 50% strength reduction occurs after 70 hours !)
Glass-fibre.....It has no true melting point but softens at 2,000 °C

Based on these figures, but, mainly that I can get glass fibre more easily.....I am going to experiment with Glass Fibre Wicks, once my resistors and fans arrive through the post from Rapid Electronics... ......
I will report back on any progress, especially if I manage to 'soften' the Glass Fibre ( 2,000 °C ).......without.....burning up the entire Panzer [move][/move]
Regards, Alb.

Excellent research work,The Kevlar wicks were available to my pal Dan and the testing we have done shows no burn or slowing absorption rate.The major difference is the resistor,after testing several type the ceramic,enamel coated wire wound are the best.The other reason for choosing Kevlar was a supply issue,Dan had the material on hand as did I from previous jobs we each had been involved with.On another note your testing of the Glass Fiber Wick is important as another option for wick material.Please post your experience with the glass fiber material. On the subject of our smoker design I will be posting a video this week of both the modified H/L smoker and the new design which Dan has taken from Idea's on paper to a working unit,and a complete parts list. Cheers Blake

I believe this is the smoker problem solved in a different direction,fog fluid,fan powered,Kevlar wick,fluid matte,and no spill filling system.Next application is the Kill mode smoker coming soon.
