Title: Fourth Boat Finished This Year - Prestwich Sigma
Post by: Andyn on April 16, 2021, 12:12:15 pm

This one is another rebuild, though I can't claim to have done too much to it. Picked it up two Sundays ago from an old mate who hasn't been boating in a few years, ordered all the parts for it, then challenged myself to get it ready for the water during this week. It's a Prestwich Sigma - high sided varient, that I've changed the engine over to a CMB 91RS. It had a CMB 1.00 in it, which I'll also test.

I stripped off the orange and white vinyl wrap that was on it (not to my tastes), then all it needed was a complete radio refit. The Chinese plastic radio box departed the boat and was taken straight to the outside bin (where they all belong {-) ) and replaced with an Aeromarine glassfibre one. I made some ally angle servo mounts for it, some new brackets to hold the box in, then fitted a Savox 2271sg brushless rudder servo, Futaba 3072 for throttle and hitec hs430bb for mixture. Radio is jeti and it's all powered off a 7.4v lipo. Pushrods were all made from 3mm stainless. Unfortunately I ran out of green silicon fuel tubing halfway through re plumbing it, so that'll be completed when the new roll arrives in the post
Should be on the water this Sunday

I liked the orange Andy! But I do have an orange car and motorbike!

Nice installation as usual.

Thanks gents
I'm rather fond of orange too - hence my bright orange Jeep and two orange boats, just didn't like how this had been done. Might eventually spray the lid green :-))

Video below, only ran it twice today as after the roll the rudder servo arm screw had come loose and it was a pig to get to so I went off to repair our rescue boat instead %)

Since the first video I've replaced the stinger with a strut, the cheap Chinese 6" setback rudder with a 4" Speedmaster one and added a turn fin. Needs about half a degree of downwards strut to stop the nose bobbing but overall much happier with it
