Os50sx Heli in a plank?

[moyesboy]

Just wondering if my spare Heli engine could be used in a plank? Us forums suggest don't change the head. So all I need us a prop driver wudruff key and a suitable silencer but I suspect that will cost most of the price of an irvine40 for my lads trainer anyway!?

Yes you can use it , I have done it many times , but you do need the parts you mention.

Thats a coincidence, yesterday at the field one of the guys flew a very old club 20 with an old I think 25 heli engine in it on a tuned pipe. and have to say it was darn fast.

[moyesboy]

can anyone suggest a suitable silencer, and where to get the prop driver?
There will be a comfortable excess of power I think so any old bean can that fits it will do!

Just engines may be a good place to start the search

the old os50sx should have come with the prop adaptor
the hyper never has
so somebody that has had a few 50sx's before the hyper came out should have one lying around in the spares box

the exhaust a cheap one off ebay

tracking a couple of hopefully cheap mufflers on ebay.
I started with a 50sx non hyper but in a used raptor so I never had the prop driver, but I'll use the old sx head and carb to start with (I changed the head and carb to make it into a hyper).

So I will start an appeal for a 50SX prop driver in another thread thanks for the info.

Thanks nightstalker, looks like I already found a prop driver, started another thread looking for one:

Looks like £13-15 quid for a j'en slencer and I'll be done, though I'll look for a siloencer in the club.
