| I'm glad you could get and answer. I asked the same question over a week ago and couldn't even buy an answer .
Did someone else named Fireman-Dave rip someone off in here. that was my first post anywhere , I thought i asked some valid questions???
I'm running x-cell gas graphite ,23 puh with wt603 card . needles 1 3/8 and 1 3/8 . temps with a raytec temp gun are 290 degrees on a 80 air temp. running ozark fuel on amsoil 64 :1. I have the new bergen muffler on the exhaust. the heli cools quickly but I'm just not sure of the temp, it just seems a little to hot. I'm running 700 mm mains and 105 mm on the tail. 1650 head speed in hover at 5 degrees pitch.
we did a test with a friends bergen conversion , he has a g23puh with a wt603 carb, min air 4030 muffler system, needles low 1 3/8 high 1 1/4
reg pump gas on amsoil 64:1 he has 690 mm main blades with 105 mm tail. still 1650 rotorhead speed in hover.
His temps ran a steady 240 degrees with the same outside air temp.
only three main differences between the 2 helis
1> his has the bergen fan system.
on my gasser i was very careful to set the shroud to fan clearance to 1 mm. I also sealed the bottom of shroud to the mounting base to reduce the amount of air loss or blowby.
2> the muffler systems- does the aluminum being thicker retain more heat than the stainless steel ?????? I had heard on this and other forums that the min air 4030 was a little more restrictive than some people liked. they said to much back pressure.
3> the fuel again i have seen other posts that stated the latern fuel ran hotter but 50 degrees seems a little excessive. I had made a mental note to ask Bill about his comment about adding more oil to this fuel but is changing the mix to 50:1 going to drop the temp 50 degrees???
Seems a little far fetched to me.....1/2 oz = 50 degree drop
now i love the latern fuel for the following reasons
1. NO Smell, no smell, no smell
2. No Carbon ( at all-- cleanest motor inside i've ever seen)
3. No fin buzz period......
4. No powerloss
5. Did i mention no smell, no smell ,no-smell
one other difference between the 2 birds, mine has 8 gallons of fuel through it 2-ozark, 6-gasoline all on amsoil .........his has 1 1/2 gals gasoline .
Those glow freaks can say what they want but this heli climbs like like a demon, i have not done a full power climb yet.......I'm to scared to. If it climbs this quick right side up what's it gonna do when i finnally get the nerve to fly it upside down. Heavy- who says gassers fly heavy mine stops with just a touch of left stick......govenor who needs a stinking govenor just set it up correctly, less electronics to worry about. Oh the Auto's , this thing will hold itself off the ground seems like forever!!!!!!!!
It has taken me over a year to get things to this point with my Gasser. I work 2 jobs, 56 hour's a week with fire dept and about 30 hour's a week with local hobby shop..... Oh no not one of those guys . Thank goodness I've got a loving wife that said I get to quit the Hobby shop . Tomorrow is my last day 04-30-03 , Chopper is right , weather is right and on my very first Saturday off in 5 years I'm going to sanford for the fly in. I wanted to go to Sulfur La but I could not get coverage at the fire station.......
My wife said all I have to do now on my days off is FLY,FLY fly (and work on a few honey Do's..... She said something about needing the step ladder out of the barn to add a few things to my list....... Next year gonna be in birmingham, going to sulfur , going ,going going over the edge is what I'm doing....... going to climb down off my soapbox now and let someone else talk for a while.....
Oh and by the way I've been lurking in this forum for quite a while now and want to sincerely thank all those who have helped unknowingly with my quest with the gasser. your help has been greatly appreciated...
Sorry about such a long post , I've been cooped up for such a longgggg
time......
