Brilliant, just love your experiments and "make and mend" attitude. We have our very own Jack Hargreaves on the forum! Looking fwd to seeing that jet fly.

Yes is the answer!. We are modeller.......so anything is possible. I have done some experiments in the past, and it can make a good core, covered in brown paper and strengthened with a carbon rod. I would cut up a few small pieces and try out some different techniques. Worth a try at least!.

Can you give me a call sometime about this please? I sent you a pm with my number, Thx Simon

Flite Test Voggen 5mm Foamboard

Nigel Thunderbob was made of the type of foamboard that has a thin paper covering each side. I got it from Amazon, free post.

Yes please, I have rejuvenated more basket cases than I care to remember. Please send me the details!.

Ali Express. Just got a bag of 20 2mm nuts and bolts. Not sure what they are up to, but 7 days from order to posty arriving. Amazing!.

Yes it can. Our club trainer uses mode 1 to 2, and no issues all year!.

Thunderbob is made from 5 and 10mm foamboard. Two ply joiners on wing and 1/8 carbon spar under tail which is rock solid. Brilliant stuff, it does take some getting used to though. I have now built 8 foamboard models and the fun for the £ cannot be beaten IMHO!.

Thanks Nick The odd thing is, that its a normal Seagull manual with Seagull on the front, but at the top of each page is printed Carden Extra!.

Due to our patch resembling a lake, I have only managed a couple of test fights so far. Absolutely no vices at all, and for once no trim needed. Early days, but its definitely a keeper. I get more enjoyment out of models like this, than my £350 jets which spend most of their time in the hanger!

I recently purchased a Seagull Edge 540 64" wingspan model BNIB via Marketplace. Looking through the very brief instruction manual, each page is marked "CARDEN EXTRA" at the top. All the photos match the model, so its the right manual. Despite trawling the net, I have yet to establish what "CARDEN" actually means. Its obviously some sort of variation / mark / type of the full size but I am interested to find out a bit more about it. Can anybody shed any light on it please?.

The original Thunderbob was a 70cm Depron lightweight model. http://rc-plans.com/catalog/item432.html I increased the plan to 1100mm wingspan, and constructed it out of 5 and 10mm foamboard from Amazon.(£25 for 5 sheets delivered). All edges shaped, filled and rubbed down. Used a 240v and 3s Lipo powered glue gun throughout. It was painted by hand in Farrow and Ball green emulsion I got from the local dump (where most of my modelling paint comes from). One coat of hand applied, water based satin polyurethane varnish (again from the dump). The Ailerons are controlled by two new mg 17g servos, with plastic spoons cut in half and painted black to provide suitable covers. Control surfaces are hinged at the top only by wide reinforced tape. 4s powered, weight circa Lb4. It could be constructed in a week, but as I was enjoying it so much.............took a month!

Here we are Bonzo...........

Thought this might appeal to you. Thunderbob. The original plan was for a 70cm Depron model. I turned it into a 1100mm span Foamboard cartoon scale job, three sheets of board = £15.00. Interesting laminated three piece wing, resulting in a wing "section". AUW LB4.

Always carve one out of blue foam. Great model, had years of fun out of mine!,

My version of the Thunderbob. Three sheets of Foamboard £15.00

Well done Bonzo.......always enjoy your stories!

Problem solved. Found a programme that works out the FSA and produces the relevant design criteria,

I am in the process of modifying a Flite test foamboard model to fit a 70mm EDF. I have several models of this type, all without an efflux tube. I am sure it could be a very complicated subject!. However, reading several posts, I have found that for a 70mm EDF, the yardstick is a length of four times the diameter = 280mm and a reduction of circa 20%. Has anybody tried this or similar?

I have been getting mine from Amazon. Large sheets both 5 and 10mm. £4 and £5 a sheet post free. Strong and light.

FMS 3 Bladed 13x5 prop and spinner / hub. Balanced. Bought this for a project that never happened, sell at cost.

Another vote for Hobby Rc. Some of our guys are placing orders with HKUK, who are in the process of getting up and running again.

I started building from Foamboard at the start of the pandemic, and have gradually refined and modified how I use it. So far from the Flite Test stable; Versa F22 Vulcan Viggen and at present a larger (40") Thunderbob. They have all flown brilliantly, and the F22 is my go to model: RAPTOR 4S 1500 23.1OZ 64MM 60A 40.0A / 622W All are 5mm Foamboard apart from the Thunderbob which is mainly 10mm. Brilliant material, which can be turned into great models. The F22 was £11.00!
