I am in the process of building my Hirobo Super Cobra and want to make the cockpit (plus canopy) removable to allow me to get at the starter motor and receiver Lipo's for charging.

I was thinking of using a few rare earth magnet from Radio Shack to hold the cockpit in place.

Would appreciate any comments, especially on whether the magnets might have any effect on the 2.4ghz JR receiver which will be 2-3" away.

Thanks

David

I've got a Fusano Airwolf fuselage on my TRex-450. The entire front of the canopy is held on with nothing but small neodymium magnets, 14 total. I also had a DarthDrk JetRanger fuse on my MX400 held on with same kind of magnets (about 6mm round x 1mm thick). Both running 2.4Ghz Spektrum for over a year now. No problems with either one. Since my heli's are both smaller than yours, the magnets are closer to everything. Yours should be fine.

BTW, those magnets are a lot cheaper on ebay than RS. I picked up 50 for less than $10.

I just ordered 100 from amazing magnets. $15 shipped vs 1.99 for 2 @RS. Not too hard to do the math there!
Thanks Doorman!
