Hi, George! You are always inspirating! I have a taste to make something simmilar :-)

George, I would like to have such nice flops as your Avro :roll:

Hi Roman,

yes, please do...
As for the prop, I have some black wide bladed props which might be more suitable, I do not know, however when the next trimming opportunity will be.

Hi Tim,

very interesting questions, all of them.
I am not going to start straight away, I need some time off the Roma. It is not looking good in terms of spare time in the near future, so I would not want to start a demanding project at the moment. Maybe getting lazy... as for flight trimming, I am more ore less satisfied with the general behavior, it is not going to be a complete flop like my Avro.

Not many changes, just a more detailed model, both in structure-finishing and in details.
I do know that the tail must be as light as possible. The nose is pretty short and the addition of 7 grams of lead was not something i liked.
Also, although the 1/32 scale chosen seems right it is considerably less than the 1/20 I prefer, so it makes detailing a little different.

As for time required, yes, November in Nijmegen is perfectly possible.

Please note that I do not specify which November :lol: .
Not this year, but perhaps in 2018. All is not going to be building time, I know there will be some occasional distractions.

George, if you are limited to a 5" prop, maybe you can try a wider blade or higher PD?
Great to hear that you plan to come again to switzerland. I try to organise nice and calm weather for us.

Very impressive George. I'm sure you must be pleased with that as a start to trimming.
I'm interested to know what your plans are for version #2. Are you ready to start it straight away or will you do a lot more trimming first? Have you already got a list of changes for #2 based on the building of this one and if so what are they?
Also wondering how long a model like that will take you. Would you expect to have the new one ready for Nijmegen in November.

Thanks Roman,

I have the disadvantage of having a rather small prop. I will try towards your suggestions.

I do not know when there will be another indoor session. In the worst case I will have to wait for the 25th of March. Luckily I will be here, so it is possible to attend to your event. Now I have two Bellancas to fly :roll:

Thanks for the nice comments.

Of course, it goes without saying that I also have a few videos of not so successful flights :oops: . I chose to upload the best one and hide the rest ;)

Propeller is a Peck Polymers 6" prop cut to 5" for take off clearance.
Rubber motor used, was a not properly prepared, wound and unlubricated loop of 3/16" with a length of 43 cm / 17". turn were about 800.

I was rather lazy to try for more, I also had the wings rather unglued nd had no glue with me to fix it. (So much for "be prepared"...)

George, I checked my Vagabond...
Prop is a 8" Peck. rubber is one loop 60cm long with 3/16".
I just found out, that I didnt note the exact rubber combo in Nijmegen. The combo above is from good trim flights outdoor. But Nijmegen must be close to it.
I have to remember to update the datas at the next occasion.
Hope it helps anyway.


PS: I also checked the 24" Travelair which is a bit heavier and flies faster.
Prop is also 8" Peck, rubber is two loops 60cm long of 1/8".

George, congratulation. It already flies very nice!
It has the same wing-span as my Piper Vagabond. I will check the rubber prop combo when I am back from work.

What rubber and prop have you got in it at the moment George?

That flight looked good, almost there ;)
