Try that with a big block that has the steel collet. Medium blocks have a brass, and in some cases, aluminum collet. I tried a battery terminal puller on my FA-150 and all it did was bend the puller.

Really nice flying plane, and with this engine, very fast at full throttle, but very scale like at low throttle.

Damn that's purdy!

Well here’s one of the Frankensaito’s. In a L4 weighing in at 15 pounds To Recap this is the Saito 180 with .030 shaved off the case. It is turning a 17X8 at 8200 on 15% glow fuel and CH ignition. It has unlimited vertical. The test pilot was surprised and impresse.
So once again thanks to SRtelamaster for the help in getting this in the air.

it sounds like a slug im the carb. Can you get the hi end needle valve out? take a syringe with fuel and push and pull some fuel through the valve. I habe had that same problem with engines when i ran fuel with castor.

I've kept very quiet about the 115, I don't want to upset the two guys in the whole world who liked them
I would have bought one IF the price wasn't so outrages

Penny wise pound foolish

Okc my dad was a teenager during ww2 and straight after that conflict was over the vincent appeared in different guises people mostly remember the black lightning.Dad hero worshipped the vincent and his favourite saying was 'guaranteed to do 120mph' while smiling at the memory.Triumph and indian among many others are cashing in on the retro boom of not just motorcycles but art deco radios you name it.Soon we'll be able to buy open rocker saito's again,i hope they don't include a 125.

ps if you like to see and hear modern thundering vincents racing you tube 'irving brothers vincents' cheers

People want to compare the price of the FA-115 to the FA-100 yet the FA-125 costs slightly more than the FA-115 and cost no more to produce. It was all a marketing plot to make the FA-100 and FA-125 more attractive from a marketing standpoint. The production cost for all 3 engines would not differ significantly.The FA-115 is basically an FA-125 top end on an FA-91 bottom, the FA-100 is the FA-91 top end on an FA-125 bottom. We're not pulling stumps here, the FA-100 makes little sense and an FA-120 will outperform an FA-125, albeit at a size/weight penalty.

The footprints of the FA-82 and smaller coincide with .40 sized 2-strokes, the FA-115 with .60 size 2-strokes and the 120-180 big blocks with .90 size 2-strokes. The FA-100-125 are the oddball size. Saito is eliminating glow fuel engines that do not coincide with gas counterparts.

I'm glad I bought my FA-115 before the corporate axe fell.

I will check again but it looked clear before. This being an older Saito I wonder if it could have been the fuel I have on hand? I was using 15% Nitro and if memory serves older Saitos like a little less Nitro. Any thoughts?

Saitos love nitro. Where did you get that idea? Benchmark fuel for Saito is 15%. I've run as high as 30% and it really made my Saito howl.

The older ones with higher compression I have heard required a low nitro level. My engine is the old big case .80.

Well if I come across a 115 at the swaps, then I will snap it up and compare against the 100 and 125 I have. I ran both in my Mustang, the 100 did OK, the 125 flies it very nicely. Love the sound as it scoots by.

OKC
it could be just bad fuel. I have seen old fuel do fine but if there was any kind of a air leak it could just be bad.
As far as what nitro % I wonder if that didn’t have something to do with $5 a gallon more it coast to buy 15%. You might have heard you don’t need that. More then you can’t run that. Hec I use to hear it all the time. ( what you need that much nitro for? You can’t tell the difference). This coming from guys who fly a gallon every two years.

I don't buy fuel that often so it could be old fuel. I don't concern myself with the cost of fuel because I don't use that much. I have 2 and 4 cycles in my fleet so 15% was good all around fuel for what I flew. I much more concerned to have the correct fuel for the engine I am trying to run. I may see how one of my 2 cycles run with the same fuel before deciding what to purchase. I do have a lot larger range so keeping multiple fuels on hand ma be required. I have 2 cycle engines ranging from an OS .10 FP with a large variety up to a Super Tigre S3000 and a Moki 1.08 ci. Four cycles range from an Enya .46 Series II to a Magnum .91.

OKC.
Yeah i have the same thing here. So i just run the same fuel for my 2 srokes that i put in my 4 strokes. What is throwing a wrench in the works is the gas engines i have been acquiring. They need a different fuel, darn it

Been sticking with just 4 strokes in glow. I have an OS 91 that someone gave me, I cleaned it up and put it back in the box, never to be run. The Saito 91 he gave me though is in the 4*60. Between those, and me gas, I now need 3 types of gas, 20:1 for the 4 strokes, 30:1 for the DLE, have 3 of those, and 50:1 for the DA 100. The 4 strokes are easy, Wildcat 15% 2&4. I have a case of SIG 4 stroke 15% to try this year.

I haven't dipped a toe into the gasoline engines yet but I may at some point. When I run into something I can't power out of my current engine inventory then I may try gas. I have specific size limits for projects and if I retired today I still have enough projects to keep me busy for several years if not longer.

I am eager to hear the NGH38CC run. I have a pair of them for my B-25 and they are stacked, no mufflers. 38 CC 4 stroke gas engines should sound pretty sweet on the Mitchell. I really wanted a pair of FG30somethings for it, but have a feeling they would be too small. The NGH has a track record for the bird I will use them on, plenty of power for it.

Plus one they love it.

Guys here's a photo of a new indian scout/bobber fuel tank before i repaired it.The squeezing knee dent in the left hand side is matched by one on the right.At the rear of the tank is a shallow scooped out dent that strongly resembles your gonads.Due to our own misadventures over the years we felt some empathy for the customer.

SrTelemaster150
and an FA-120 will outperform an FA-125
thanks for all the info,I didn't think of it that way, but why do you say that in my quote ? accordingly to Horizon's/Saito's specs the 125 will swing a larger prop at a higher RPM,, is it not true ?

I've run 10% nitro in all my Saitos for years. When I lived at 4000' ASL I ran 15% in my 2 and 4 stroke engines. Now I'm at 1700' and don't need 15% for good performance.

Not sure about marketing plots (ploys?) and corporate axes, on the Horizon side (US distribution and marketing for Saito) we price according to the cost of each engine. The FA-115 was not particularly popular and had a similar cost to us as the FA-125. We sold the last FA-115 about a week ago. The FA-100 and FA-125 remain steady sellers.

The three jaw puller works fine for me. I felt these were the kind of tools I didn't need to spend a fortune on, and the bargain brands work just fine for the job. One came loose with a loud bang. They surprise you. Sometimes, all you need is heat from the Monokote heat gun to make them come right off.
