Thanx VC. I just logged in after ur call. As u know I rarely visit the forum. And instead of going to the most recent post in d thread, I started with D 1st one and read each one to d last  8-)!!! I never went through this thread. It re-livened my memories of working in d project and feeling proud to be part of it. I m recalling d days when we toiled day in day out like SLAVES to meet d deadline - burnt components, burst lipos (!)....
BTW I think forum members need not be informed that credit for d build & looks goes entirely to VC  :hatsoff:- from design, material & the oddest of things to use etc. But they need to be informed that he made a die hard procrastinator like me to work to schedule   :banghead::banghead:.
I think I should visit d forum regularly, for my own good; get out of my cocoon and re-live my passion.....

VC

He! Haaah! - I remember you running around with a fully charged LiPo sparking in your hands, like a phuljhari, at 3 am!!! Those were the days my friend. Loss making effort, but what a GREAT time we had................. :bow:

Boss, I think I have accumulated enough material to make 2 more models. One for you and one for me. I miss those models. Come over and lets do 2 super fast builds. Choice of models is yours. Choose between Griffon 2000 and 8100. LCAC is too complicated. All build material at my cost - skirt is your department. You just need to invest in a LiPo, Tx/Rx, motors and ESC.

Let's do it again Boss!

You should have seen my "LiPo burst", dumb me trying to charge a Lipo with 5Amp car casset player adapter and almost burning my room.
I prefer Griffon 2000, it was the fastest of the three we built - whatever be the reason.
I have two 4000 mAh LiPo lying with me after an esc failure crashed my boat.

VC

I would prefer the Griffon 2000, too, based on its performance. However, the only problem will be the Thruster Shroud Ring. Remember? Let's  work out an easier alternative.....................

I have been dreaming (as usual 8-) about making a 46 nitro hovercraft since I saw some pictures and details in a Boat Modeler magazine several years back. I'll try to scan and upload the pages if anyone is interested, provided I can locate the magazine in my book-self.
Another project in mind for long is a working hydrofoil boat. As a class 10 student I made one static scale model of an US Navy hydrofoil boat from card board boxes of shirts invitation cards .... and I gifted it to a junior for his school project :banghead:. I still have card boards cut out for another one. But it was too small (just the length of a shirt box) to be converted to a working one, so I lost the motivation. Now I am planning to convert my airboat to hydrofoil; have the foils & struts ready but ........

A long time ago I built a hydrofoil like in Sydney harbor but with a long prop shaft to get to the water when up on the foils
it did get up on the foils but didn't control very well and end up at the bottom of the lake lol
I will try another one now brushless motors have more power to get a better lift

hi friends
you have very good forum .
i want to build hovercraft but i cant build skirts
who can help me to make skirts ?

VC

Hi! Welcome to the forum. Making skirts for Hovercraft can be easy or difficult and it all depends on the size / scale / weight of the model. If you could post some pictures of what you are trying to achieve, we could all help out.

I have been planning to build a hovercraft for quite some time (even before I joined this forum). So planning to start one once I am back home next month end. Hope this would be the last round of treatment for my sister and she would finally be rid of the cancer. I wish to restart my modelling again.

Need help in sourcing the ripstop material for the skirt. Searching for it not just for the skirt but also for a RC Skydiver I have been planning to build. On going through your hovercraft builds I find that you made the skirts using this material. Two years back I had found a source for Parachute Nylon but he wanted to sell a min qty of 100 mts -too much for my needs. Keeping my eyes open for an umbrella manufacturer but not found one till now. Can you help me in getting the stuff?

Thanks all. Good to be back, though nothing to contribute as everything is in disarray as we are still settling up our new home. All modelling equipment still in crates and cartons. Hope to start off again soon.

Baijal Sahib, firstly all the very best for your sister, I am sure she will beat the dragon. The skirts were made of the car covers available at any auto deco shop. These are commonly called rain or dust covers. Hope that helps.

thanks vc !
if show me picture of skirts , i can build it !!!

@VC
Thanks for your wishes.

Your suggestion to use car covers is great. While skimming on water, how to you prevent water from collecting at the rear end of the skirt and dragging down the hovercraft. Any holes to drain the water out?


a.mehran

i use car covers .
but i dont know how to cut this
