Trex 700n Flight times and Header tank

[LordExcalibur]

I just got a Trex 700N and was wondering what sort of flight times I can expect from it? Its fitted with a YS91 and I only hover and gentle circuits.

Can I fit and would I benefit from a Header Tank, I have one fitted on my Raptor and always liked it as I used it a a sort of reserve tank, Fly the main tank to empty and then land, but always had a couple minutes safety from the header tank.

Regards

I have my timer set @ 7 1/2 min and land with 1/3 to 1/4 of a tank ( no header) with an OS91 HZ. No 3D.

The last time i timed a flight i got 6.5 mins steady sport, loops and rolls and still landed with half a tank(no header) with an os91hz running slightly rich

Many thanks for the replies.

Yuppyflyer - How did you fit the tank, did you drill the frame? Any chance of a photo please?

Infact any one tell me how they fitted their tank.

I've got a header tank on my 700, I bought these Quick UK Header Tank Mounting Set Black H5511B and used the rear most fan shroud mounting. Just take the bolt out and replace it with one of the long bolts that come in the mounting kit. Saves drilling the frame.

I'm not sure I'd use a header tank on a YS91 though as it could be a pain to set up with it being a crank pressurised feed.

8 mins and landing with at least a quarter of a tank. (no header tank fitted). Sport flying and gentleish 3D.

Got carried away one day and with gentle flying and with what was probably too weak a mixture I got 14 minutes! Had to auto down though from a great height!
