A good reason not to buy cheap ARF's

Yeah 436's service has been flawless. Orders always arrive the next day. Galtech, Watts Up, and Bandit are also very good. We just got the short end of the stick down here in ChCh

Well, She flies great!. Went down to the field this morning and sat around for a couple of hours waiting on the weather, Came in good just before lunch, race for the starter and off she goes. Thanks for convincing me to have another crack at the AT-40, It flies beautifully!.


X-Jet, I have attached a pic of my bent crank. Do you think it's worth a go at straightening it?.

Thanks, Pete.

Well that sure is bent, you don't do things by halves :-)

It's hard to tell if it's able to be saved -- I'd have to check the area where the thread ends to see if there are any obvious stress cracks.

Straightening would involve heating that part of the crank to anneal the metal then straightening it and re-checking for cracking.

The problem is that if the crank has been hardened during manufacture and not tempered properly at the thread-end, it will have been weakened by the bending but the only way to tell is to do a hardness test of the material immeditely before the bent bit. Most cranks are pretty well made these days and the threaded portion is left fairly soft so they straighten quite well.

If you want to fire it off to me I'll take a look and let you know. I don't charge for such things, it's just a service to the hobby and I'm glad to help others out when I can.
