RE: ASP 180 FS gas conversion
I fit hall sensor, magnet new hub etc
The interesting part I think is that I removed original carb and make new intake with walbro carb support. I will use a modified walbro for 4 strokes
Intake is 3 parts maiden from aluminum, and is aluminum welded

RE: ASP 180 FS gas conversion
Nice job!And what ignition module do you use? Is 30:1 mixture enough oil to operate the engine?If the con rod is not roller bearing supported then you should increase oil content!

Im Using Rcexl ignition. Oil is enought only use a high quality synthetic. I had ran my saitos with 1:40 many hours and still excellent. Hopes this ASP be too. I tested many oils. Some oils burn easy and not lubricate engine. others still with viscosity. I found that almost all 2 strokes aoils are not good, , burns very easy. I found that oils designed for mix 1:100 are better oils here in Mexico i found Amsoil excellent.
In other hand more oil, less power, and begins walbro problems

Hi Max. Nice job [8D]
What size Walbro/type did you use? - I had most luck with 9.5mm choke and with accelerator pump (WT-38).

RE: ASP 180 FS gas conversion
very nice !!
I have the Magnum 180 fs, it should be the same Engine,,
a little info, my Magnum had very little compression, it came stock with 2 Head Shims so I removed 1 Shim, the RPM came up 700 RPMs (but I run it on Glow), there is a guy here on RCU that removed both Shims (but here too he is burning Glow),, so you may want to think about removing 1 of the Shims to get a bit more power,,
I get 8850 with an APC 17x8 on 15% glow and it drinks about 1oz a minute,,
what size Prop are you using there ??
BTW,, that Engine sounds as if it needs the Rocker Arms adjusted, when my Engine was new I had to re-tighten the Head Bolts 3 times and re-adjust the Rocker Arms 3 times within the first gallon of fuel !!!

RE: ASP 180 FS gas conversion
I'm using 16% Oil,,
as for me removing that Shim, I removed the Shim when I broke a Valve Spring when I had a Blade Strike,
I was thinking, with that Engine burning Gas it may run hotter and may need a larger Lash than the Factory Specs

RE: ASP 180 FS gas conversion
Its been a long time since this post, but I wanted to see for those who have converted How are there motors still running?
Im building a ESM B25 and while it would be easyer to put 2 DLE30 on it just wont have the sound I want.
So how you guys likeing your converted motors?

I know this is a old thread, but I got 2 conversion kits from Max, for 2 new ASP 1.80 4c from HK for my ESM B25.
One of these motors I have around 5 flights on in a spacewalker, but they are both basically new.
I feel like Im low on power, Im getting 8600rpm on a MAS 15X7X3 prop which according to the calc is 2.143 hp vs 3+ that most of you ASP owners are showing.
But just reread this thread and may have found one of my issues, as Im running my oil at 20:1 as that is what I thought we needed, Im sure I may pick up a few rpms with more fuel. I will try and see if there is a diff.

16*8 on petrol with ~~8,000 RPM (or less) and 20:1 oil is right. 15*7*3 at 8,600 is good. 18*8 only OK for methanol with a lot of oil.
If you don't have a roller main bearing, don't run less oil than 20:1! It will seize!

I would like to know where I can purchase just the ring to go over the hub.
Would be good to know where to buy a length of aluminium tubing and cut my own.
Need 27mm id with about 35 od.

I converted my 180 to ignition burning ethanol 10:1 sintetic.
After run in I inspected and found everythink well oiled an clean, no carbon.
Measuring the parts I noted the crank pin marked and the conrod bush oval.
In the pics below You can see the pin bush with 3 oil holes, 2 downward and a third one uppward, just in the area where the pressure is higher.
I balanced the engine as per the book and made another bronze bush, only two holes down.
Have one of You met this issue???
Note 3 holes in original pin bush.
