I think this might be a first, I managed to set my V-Blades on fire today, I was taking them off my heli and without looking where I was putting them placed one of them directly ontop of my 12v battery, this must have shorted across and the whole thing burst into flames within a second. I guess not having cleaned the blades after flying the oil covering them must have gone up. Now I have just got to see if I can fix them !

Damn, I wouldn't have thought that would have happened. Something else to watch out for.

Guy at our field thru his heli in the back of the truck. When he got to the field we all smelled something burning. Pulled his hei out and one of his vblade paddles was toast. The heli must have rocked over and the paddle grounded out against the fieldbox terminals!! Toasty!!!

Buy some new ones & save them for night flight, when you can re-ignite them.

I always thought the actual CF was covered up in gelcoat?

Yeah, me too. If I could find my multi-meter I'd check mine, but the guy who used it last didn't put it back where it belongs! Somebody please check their blades for continuity. I'd like to know.

There, their and they're. It's really that simple.

I found your meter, don't know how it got in my tool box

Looks like they do conduct, very suprising.

Found my meter. I couldn't get continuity everyplace on the blade that I checked, but I could find a few places that did conduct. Gel coat must be mighty thin. Nice to know!!!

Same here, but the plot thickens...

One of the few differences I've found between the TT blades and VBlades (aside from the price).. Now we've learned that TT blades are safer around your TRex electronics too!


The area over the VBlade label is non-conductive.. The trailing and leading edges of the TT blades are conductive. I have always noticed the gel coat on VBlades has tiny holes around the edges of many of the carbon fabric weaves.. I guess this shows a thinner coat than the TT blades.

So anybody got any ideas how I can repair them or am I supposed to just bin them ? - I've been recommended to apply some glass fiber resin to them and sand it down until it's smooth, any other ideas ?

I agree with repair, scuff up the areas and maybe try to feather them out a little if you can (try not to dig into the fibers), apply resin and let cure, then block sand it close to smooth with perhaps 220 grit. Wet sand out the rough scratches with 400-600 grit, then again with 1000-1200 grit til it's smooth, then buff it to a shine (by hand or with dremel tool).
Or perhaps be lazy and just fill it in with CA.

Well since they're so conductive, maybe you can solder those holes up!
