Here's a photo of the initial on the water run yesterday at Crealy of the Vosper 73' ASRL I've been asking for help with in the forum .
Not yet finished with deck fittings & rigging aerials but performed very reasonably. it has a JP Power 480 motor driving a 25mm 3 blade prop. Powered by a 6v 4Ah LA battery with a RadioLink 2.4ghz RX. and a 15A Mtronics ESC

This is my second attempt at scratch building using a a grp hull. My first boat was an MTB/MGB built on a Perkasa hull as a semi-scale model. (see All things Rc - Power setups).
This time I have concentrated on keeping things lighter but it still weighs in at 2.5kg!
I have built without plans, relying on internet photos scaled etc using "Photo deluxe" and "Photo Express".
Virtually everything is built from plasticard apart from a 3mm liteply deck.
The dinghy is epoxy resin and microballoons, ths scramble nets are Lego!
Power is again courtesy of Graupner -2, Speed 600 8.4v using lh. and r.h 35mm props. Esc is one of those 50amp ones from the far east. These are far cheaper than the Viper Marine 40 used in my MGB, but slightly heavier and less sensitive at low speeds. Current drain (in the bath!) is up to 30A but this gives a superb on the water pace of an, estimated,8mph. Battery is a 4,600 mAhr NiMh.
(A true scale speed approaching 150mph plus).
I sail it on Ullswater in the Lake district and the Vosper Perkasa type hull shape is superb in the real waves that we get there, flying over the crests and taking aboard No water!
It really looks the part as my photos would show if I could learn how to load more than one! Can anybody help with this?

HI.just another picture update,taken at Newbrighton. gerry

Hi,
I thought that my recently finished MTB may be of interest.
It consists of 49" GRP hull ply deck / superstructure. The fittings are from a mixture of ABS and metal, to give a good surface for spray painted finish.
The drive consists of twin 850 motors and twin 50mm brass props, controlled by a JetI Navy 600 on 10 cells, this setup gives excellent scale planing, but with 14 cells the performance is outstanding. I use 4600 capacity and only select the top power run in short bursts, which gives me around 20 minutes duration on one charge.
radio is 2,4 ghz so no bother waiting for a free freq.
hope you enjoy
loz.

preliminary hull shape - still a ways to go - will spend at least a couple of hours each day if I can and try to have the final drawings available on the forum before Christmas. if anyone has any original vosper hull lines, would help a lot.

this boat has twin shafts two 777 motors twin mfa
esc twin rudders and two 7.2v buggy packs yet to
be tryed on lake as it is drained for cleaning

These are the two experimental Vosper FF. No.80 was steel and the un-numbered one aluminium.
