No, Maxam is selling one of his 7-70's and keeping the other which is going into the Pilot one Waco. -Tom Maxam

When does a model Radial Engine become a museum piece instead of flyable?
My wife gave me a birthday card a few years back with this quote from Otto Liliethal (the guy who taught the Wright brothers how to glide):

"To INVENT an airplane is nothing, to BUILD one is something, but to FLY is EVERYTHING." - Otto Liliethal

Has a lot of parallels to all walks of life - I keep it nailed to the shop wall.

Subscribed to the thread. I think I am going to pull the trigger on the SL 150 Radial for my 170CC Hempel Yak 55M. I am looking for scale flight performance, so with the weight and power output of the SL 150, it should be a good combo. Planning on the weight on the Yak to fall in the 36-40 lbs range. Any inputs and recommendations are welcome. Take care.

Jason, that is one nice engine!

Too bad these guys are not in the US, I'd send them my ST710 should it need a tune up or repair.

Send photos once you get it.

Tanks for You.....Guys,September 26 in Italy will play a show with aircraft and put online the video of my BU133 SL150 with the new engine so that you all can see the potential of this new engine and its exuberant power.

I will, should have it by the middle of Oct. I bought the Exhaust ring and software also. Luigi is also making custom length standoffs for my airplane. I needed the overall length to be 210mm (8.25") for the Hempel Yak.

I must say with the exception of translation issues, Luigi has responded very fast to all my e-mails, and my tons of questions about the motor. I should have a English version of the Manual sometime next week.

More to follow.....Take care.

I would love to see , hear and own something like that but do tell, why would it make a difference at a scale competition if the engine is cowled? Do you get points for scale sound or what?Would love to hear your answer
Rambro just to clarify.....on each flight round 10% of the score is Flight realism. This is left up to the judges on how real your flight is over your entire flight. Sound would take into consideration but so would everything else about your flight. How it looks in the air and how real your flights appear to be to scale would be the most important part of that score. Turning a scale size prop I am sure would also help. You are not supposed to be deducted for things like linkages, sparkplug sticking out, carb hole in the cowl, but we all know that if one has it and another doesn't it is going to make a difference. Still the most important at a event is how well you fly your manuevers. This is where I see the biggest part that guys make it or not. But in the end it is the total score added up that counts but it is the little things that bring you to the top. One tip for sure, fly slower than you normally would, it makes all your flight look much more real. Sorry for getting off track but the question was asked and it is a good one, i just added a bit more to it.

warks, I agree with you for the most part. I think the sound issue is a funny one. I remember when the 4 strokes came along and everyone raved about the realistic sound....well we know how untrue that statement is especially when you hear a real allison, merlin or Pratt and whitney iin person. Then the radials are starting to show up and then again its the same thing, they sound great and different but no where near a scale sound. I think it all comes down to a persons exposure to the real thing. You could have some background music playing from the time period while you fly that might do better for you and of course flying a smooth and the dreaded unefined scale speed. i have the Magnum radial and it will be fantastic but no where near a scale sound or scale size prop but it will impress the uninformed and lusfulif anyone knows a judge who can define scale speed and sound, please lets hear what he has to say but we do agree. Hopefully I made some sense. Heck I will make this a sepeate post to start the fires burning on rcu again.

Hi Everyone.

Been reading through the forum, and thought its time to join in.

Just purchased a Seidel 7-70 from Hobbyking. It has left Hong Kong, and is currently somewhere in the middle of the ocean.

I will be putting it in a Dan Santich designed P-26 Peashooter at 84" wingspan. Original flew well with a chainsaw motor with 3.2hp at 3kg+, so I think the Seidel will work lovely.

My reason for posting is to ask what is the recommended prop for this motor? I would like to order the prop now, so everything is ready to start the running in process pretty much as soon as
it arrives, but without the instructions I have no idea what prop to use. Hobbyking says 22*10 to 26*8 and Seidel says 24*8 to 24*10 so no real help there.

Any ideas guys?

Hi, I have done a lot of running of my seidels. The nature of the peashooters flying would suggest a 22X12 or a 24X10. Both these props load the engine at 5600 rpm. The engine can turn a 24X12 at 5000 rpm. This might be the best due to unloading in the air. -Tom Oh and I ran mine on a 22X10 and that was too small!

Thanks for that, I will grab a 24*12 and 24*10 right now..... never hurts to have options.

A friend of mine has a Saito 170 triple in a Seafury, and its awesome. I have a Saito 100 flat twin in a Hangar9 Pawnee (knife edges really well[X(] ), but thats it for multi cylinders in our
club. Kinda hoping the Seidel will make a few drool stains

All the bits are on their way, so hopefully in the next few weeks I can get stuck into building!

S.L.engines ,

Non ho alcun problema con quella risposta . Stai per essere sinceri .

Una osservazione sul tuo prodotto. Il motore Moki ha un buon riposo e un buon fine top , ma la transizione dal minimo al fine all'inizio lascia a desiderare. Ho visto molti aeromobili di grandi dimensioni con il motore Moki provare a fare un passaggio lento basso attraverso il campo e il motore al numero di giri ridotto suoni orribili.

Da quello che ho visto del tuo motore 150 sembra essere la migliore transisiton dal minimo attraverso l' intera gamma di giri di un motore a gas che ho ascoltato. Abbastanza e di realizzazione ! Non vedo l' ora di vedere i video di aerei in volo con il vostro motore da 150 .
[/ quote]


We have been displayed problems with the video, we are trying to fix it quickly puts it back on line.

Hi Jason

This week we are preparing for a major local event will be this weekend after we will finish installing your engines and put them in a test bench to run in and then send them to those who bought them.

Well My Seidel 7-70 has arrived from HobbyKing.

Ordered it on the 11th and it's arrived today, the 21st.

Not bad at all I reckon.

Now to put it on the bench and get it running [sm=teeth_smile.gif]

What oil is everyone using in the7-70 Seidel? Instructions state 10% for running in and scaling back to 6% after several hours and recommends a synthetic oil,
but I was wondering what people are actually running in it.....Castor or Synthetic, or a blend.... and if synthetic, what brand of oil.

Also, are people using a different prop for running in compared to the "standard" flying prop. I have a 24*12 on its way. 24*10 on backorder, should
I be getting another size to run it in?

Instructions are...vague... shall we say.

Lovely looking engine...can't wait to get it running

Greg
