6 inches at tip 8 inches at root 27 inches long. I come up with162sq. in.


I changed this as I put 17" long and it is 27" but the 162sq in should be a good #

The ton
Don,

This is a picture of an La 10 set up for C/L.
The venturi is from Jim Lee Machine shop and the Needled valve assembly is the now unobtainable assembly that OS used to make for the FP 10. The muffler is a custom unit by Scott Reise that also fits the LA and FP10/15 engines. The venturis are easy to obtain, the NVA's are unobtanium.

I wasn't following this thread but the AP .09 and .15 which is just an overbored .09 are still being made. They are much cheaper than OS stuff and almost as good.  I just flew my AP .15 with a homemade venturi/needle valve and it went pretty good. I got dizzy anyway.  A carb and needle need to be scrounged.  I have seen an .09 with a control line carb and needle, but don't know if they are still available.  A pressure fitting can be screwed in the top of an insert and a remote needle or whatever.  They are a BB rear exhaust which is kind of kool, and $35.

The one with the black head is the .15 and the c/l needle and carb. The other one is the .09 with the muffler hole enlarged and a new stinger to allow it. I also made an exh. extension for a pipe or? They are kind of the new chinese Cox replacement IMHO.

Don B.H.

I will be wiring the carbs open on these 2 models...

Hi Aspeed, I believe the AP .09 and .15 are 4 1/2 oz and 5 oz engines. If that's true,

then they are way too heavy for the wing area of the Sterling repros and Ringmaster Jr.

Their performance would be seriously compromised by the heavy resulting wing loadings.

I think The AP .09 would work okay in a Flite Streak Jr or an Ackromaster and the AP .15

would do very well powering a Profile Peacemaker.

Yes, I just weighed the .09 and it is 5.0 oz. without the muffler but with the rc carb.  The .15 would not weigh any more than the .09.  I like the Norvel .074 too. Just waiting for a project to put mine in.

The OS .10LA is a good fit but the muffler is to big

Don B.H.

Just kidding! She is ready to go...
This engine comes in at around 4.5oz with out muffler.
The plane comes in just under 13oz. RTF

Don B.H.

So no one else has this model ?

Not me,but I'm working on a Midwest .15-powered ME-109 (my second). It was my first "big plane" in 1973!

That doesn't look like any of the mufflers my OS .10's have.  they are smaller dia. and about the same length with the little extention that comes with them.

Don B.H.

I know ... It was I joke , that is the muffler off my ASP .75

I am going to run this one straight pipes..

I built a Ringmaster Jr. in the mid-fifties and it flew OK with an OK Cub. 099 and McCoy .098.

It flew even better with a McCoy .09 diesel and a K&B Greenhead .09. A Cox TD .09 would be another great choice.

Later engines such as the OS, Magnum and Thundertiger .10 engines are much heavier and when you add the muffler it makes a small model like a Ringmaster Jr. a bit nose heavy.

Don B.H.

Muffler, we don't need no stinking muffler.
I know we need to be responsible now days and act like adults. I fly in the country just south of Mason Dixon line and the closest farm is 3/4 miles away. This one will make some noise...

Don B.H.

So how is that Me-109 coming I know youhave been building ringmasters and P-40s and akromaserts but come on I want to see theMe-109.
I ordered one but they were out of stock so I got the Brodak Ringmaster Si and another ring Jr. You see I have 5 Grandsons and they will be
the right age soon.

BtnFlyGuy

Well! as it just so happens, the ME-109 is ready to go except for breaking the engine in ...The tail wheel area has been repainted to cover the off color fabric reinforcement and the spinner is going to be the correct size. Thanks for asking!

I'm thinking for this 27.5 inch (700 mm) span P-40 airplane would be well suited for a Gilbert .11 Thunderhead engine. To keep the nose light, one could leave the twin muffler stacks off.

I've got a Midwest P-40 Warhawk 33" CL kit, targeting my McCoy .19 Red Head for it. Clearing my plate of other projects, it will be a future build.

I don't know if the 10LA can use a 15FP-S NVA, but there is one on E-Bay:

I don't know if an Enya .09 CL NVA will work, but here's one also from E-Bay:

I have those needle valves and i got them from the same person in FL but I don't know if they work on the 10LA.
The spray bar may be to long and the enya 15 is larger but the .09 may work.
If any one is looking for an old Veco or Perfect tank let me know.

GallopingGhostler

Wow, you seemed to be well supplied there, Don, I have a stash but not that complete.

Don B.H.

A friend of mine had a hobby shop and closed it up about 20 years agoso I got a big box of stuff like wheels,tanks,and hundreds of little bags of parts like bell cranks, lead out wires, eyelets, blind nuts and on and on. I will never use it all. I will never use theJetex fuel pellets.

That's a really nice model!
