Does anyone know about the extra 330s fire wall? if I put an O.S 91FX on it would i need to strengthen the fire wall?

If anyone can help it would be great.

Doubt it---I've got a YS110 & "Hyde/Mt" on mine---Been flying the *rap out of it---No problems---Before you mount the .91, point the nose down & drip saturate all the firewall joints from the inside with thin "CA"---Then go fly the *rap out of it!!---(Your mileage may vary)---

Thanks very much tande!

Are there any other changes that have to be made in or on the plane?

M64

Well----I've not made any SERIOUS changes, although I am using larger dia. wheels (3")---Also 1/4" length of large fuel tubing under each canopy screw hd. (allowing it to compress & act as a lock), they can & WILL vibrate loose!---I just happen to like "Sullivan" tailwheel assy. & so thats what it has---Thats about it, all the other hardware (except wheels) seems to be good, IMHO, maybe the "Best bargain in the store" for the money----OH! & the control surfaces are VERY sensitive!!---Especially the elev.---It's HUGE for the size of the airplane!!---Now about SERIOUS changes---I am considering cutting the elev. counter/balances off & attaching them permanently to the stab & possibly shorting & doing the same to the ailerons (4" or 5")---(I'm sure you can tell, I'm NOT a 3D flier)---Hope this helps---

Thanks again. can you post a picture of the screws an fuel tubing assy on your canapy it would be a great help.

Thanks very much.

Not "Rocket Science"---But it doe's work---Tighten hatch bolt only enough to compress tubing approx. 50%---

That is very clever! I'll try it. thanks again.

Did you put a bigger tank in your extra?


M64

Can you post more pics of your plane? it looks great?
What size tank are you using and how long is your flight time with it?

Thanks again


M64

as with most arf / rtf make sure you go over it with zap or flash

what do you mean by 'zap or flash?'

M64

No, I used the stock tank---

can you post some pics of your setup inside your extra.

what is your flight tome with the stock tank?

M64

Stock tank + YS110 = 12/15 min. I guess---More than enough for me!!---

great pics. why 2 batteries?

M64

Just do a search on "Redundant batteries"---Easier than me trying to explain---& I needed tail weight anyway, might as well make it usefull!---

is the YS 110 a 4 stroke. can you post any pics on the engine, cowl, etc

Thanks

M64

Yes, the YS110 is a "Supercharged" four stroke---

thanks for the pic!!!!!. Do you have any pics of the plane in flight?

Thanks

M64

Nope Sure don't---

Do you have pics of the underside of your plane including the wings?

Thanks
