Bert, Is the FP using the air bleed carb?

Yes, but it is not staying that way, because it is terribly inconsistent. The vid shows what appears to be a nice running engine, but throttle response is terrible.
Same as Dave did with his FT120, I am going to close the airbleed completely and let the solenoid do its magic.

All, the wiki pages require rewriting. It's not a huge effort but it will take some time. If there's any specific pages anyone needs first, please let me know and I'll prioritize those pages.

To me they all are equally relevant, so take your time...

Hello Gentlemen (Ladies)... What did you do this time raleighcopter,

@ Cat1 nice job on the demand regulator, as expected you would pursue the endeavor to make one.

No need to answer, it was more of a facetious statement, Its a better place over here anyway... Giant Scale News is also a good local... a bit of rivalry with RCg, why Jason put Giant Scale News in their "bad word list"... due to an upset partnership.

Yes, but no idea how economical that is for you, being in Ireland. I get them from www.technirub.nl

Lightbulb much cheaper then here yea

https://www.technirub.nl/rubber-tril...r-type-b.html\

The cheapest localy is about €4 each...

Love this way of mounting engines besides less noice it also reduces/ avoids damage during poor landings. Also less weight then a nylon motor mount.

Il ask them if they ship international
Thanks

They also have small o rings l have to measure what are used on needle valves and the fuel filler valves that started to leak air.
What material is best for our use?

Oh my, that indeed is pretty expensive... If they don't ship international, let me know. You'll need to have a bit of patience, but in case needed, I can order, say, 20 pieces or so and send them to you.
But I would not know why they wouldn't ship int'l...

For methanol NBR is OK, all applications.
For gasoline, Viton is the better choice.if the seal has to allow movement (like needle valves). For static seals NBR suffices.

Post saw they do ship intrnatinal

irland is listed ; 47,50"standard rate" ; il give them a call to ask them what they charge to put a few in a jiffy bag.
Its unlikely they get damaged during shipping.
Otherwise il see if my boss needs any of the things they have and let him pay

Wonder if there is a low cost airline flying to lelystad (airport) and then take the bus to collect it in person.
Visit the museum on the way back would make a nice day trip

My guess is that they just posted a "ballpark" figure for there "average" order most likely a few meters of extrusion profie.
A quick call will aswer that, there is no language barrier to worry about

Or else either ask a local (cough or order a life supply at once. With the the price difrnce it will become economical quickly

Looking good Dave... As Bert said, take your time

Been a slow shop week for me as the "day job" was priority this week - I recently moved "up the ranks" and am now in charge of maintenance QA for our airline - Today was an external audit week - The pressure cooker part of the job. Do hope to get some flying and shop time in this weekend though.

Being in chemical shipping, I totally get the "pressure cooker" thing. Necessary but nasty parts of the job...

Got out for a little flying today - Windy all day but calmed down this evening..

Field was a mess as it rained here all week and it really needed a mow but had a few great flights with the Kavalier - The recent mods of the fixed air bleed and the thermal isolator seems to have really helped. The engine ran great. Still a few tweaks to make idle to mid range but upper half of curve is flawless...Solid idle now and great response. Lots of power too as one of the high speed passes was rocking.

This 5 minute flight burned about 2 oz of fuel - Great fuel economy. Tried to demo some "light aerobatics" to show the consistency of the power settings and transitions.

Despite only having flown relatively few flights - I'm really starting to like this setup..
