DaddyO, did you fly the Bostonian Speedster yet?

I also built one and would be interested in your setup.

Best regards Roman

Hi Roman

Nice to see you built one too; I saw the thread over on SFA (other forums are available) Grin

I've yet to fly mine. We're still in the middle of the outdoor season and I usually start indoor stuff when the nights start to draw in and the days become cold...  (The indoor events don't usually start till the end of September)

It looks like you'll get yours in the air before me Cheesy (I'll keep you posted on how it goes though)

Cheers

Hi Paul, Thanks for your answer.

I thought I can drive in your slipstream.... Wink Now I have to do the first step... Cheesy

I will cover it and plan to fly it outdoor soon. I will post the further progress on SFA.

(I wanted to post it also on HPA. It was not enough to open a new thread and I didn't want to hitchhike yours, so I let it be...)

Best regards Roman

Hi Roman et al Cheesy

I realised that I still had a few little jobs to finish this one up. (Canopy, nose block struts etc.) Since I've been tied up with a few repairs of the duration stuff and had a couple of hours free I thought I'd best get this one ready...

Canopy is some swish acetate that you might recognise is the same I used on the Fedex job - since I have a roll of some 10 metres you can expect it o keep cropping up! Cheesy

Struts are shaped balsa covered in tissue and I edged the canopy with some of that silver jap to tidy the effect up. (I really don't like doing cabins)

Finished weight is, gulp, 19gms with the peck prop Embarrassed I may be able to shed a bit of that by using the lighter 'Butterfly' prop though since hand glides without the prop over the bed showed I needed some tail weight (don't you hate that?). It also showed that the natty leg fairings do a nice job of puncturing the tissue panel above them...

Popped it back in the box for the moment ready for the first indoor session.

Cheers
Paul

The silver canopy trim is a nice touch - I will have to try that on the Peck Pup I just finished.

What motor size/stranding do you plan on using?

Cheers Steve

The other Bostonian I have uses a 15" loop of 110 thou SS. (Although that's a few grammes lighter) I'll start with a short loop of 1/8th to get a feel of how it goes

Re: the lights
I spotted this just after I put them on - unfortunately I can't remove them easily; when I tried the tissue underneath started to tear so I decided to just live with 'em Embarrassed

DaddyO, Looking good!

The red canopy glass looks cool, so the pilot wont need sun glasses Grin.

Now that your Boston Speedster is ready, the indoor season can come. Hope to see some flying pictures and a flight report if the time has come.

My Speedster has the same weight. As rubber I used also 17" SS, But its maybe a bit to long... I was lucky and it needed no clay at all. Right / down thrust as indicated on the plan. Flew right off the building board. Still think that there must be a hook Roll Eyes But didn't find it yet.

I am also working on a Rearwin Speedster Bostonian. Here are the bones.  It will be done in red esaki paper.

Nice lookin set of bones . . .

Meant to say that mine flies very happily in right hand circles with a bit of washin on the right hand panel and a 2" x 16th strip on the back edge of the fin. ROG's pretty as a picture and stooges round for flights of @ 40 seconds - very cute design that is highly recommended. Grin

Beautiful Build DaddyO... I like the way you done the finishing... I also liked this one from the first time I saw the Plan.. and I'm glad to see your build as it will help me.. I want to build this model it looks great... but I have some questions I hope you don't mind tell me the answers....

What is the wing span of this model?...if I print the plan as is will it come out right?
I'm just come back to this hobby after some years.... trying to remember all that's involved in building...
Did you use any washout? and what's the thrust angles you used?
did the model need any adjustment of the stabilizer to counter the extra nose weight or did you use some ballast in the tail area?
Thanks....

Hi and welcome to the forum and thanks for the compliments Smiley

16" is the span and I printed mine off in bits, but yes it came out full size.
No intentional washout used, but approx 3/32 washin on the right wing.
Thrust angles are difficult to judge@ 5 degrees down and 3 degrees right (Model flies to the right)
I shimmed the tailplane  (build in a gap for the stab. so this can be easily done)
Mine's in for repairs at the moment and I'm adding an adjustable rudder to make flying in small halls less wall-banging Wink

Good luck with the build and remember to post some pics for us to see
