Default JETT 50 vs Rossi 45 in KANGKE F-20 .40

Trying to sort out a plan for the Kangke F-20 on which engine to use. I have a OS 46FX, Rossi 45 and a Jett SJ50. Im leaning towards the Jett. I never had an ARF with a wooden engine mount, will that hold up with a Jett 50? The fuel tank seems to be another issue for all of these. I thought I might try a bubblejett tank thats further back in the plane just behind the nose gear. Another way to go would be to use 2 smaller tanks connected. One up front and another behind the front gear and have 10 or 12 oz's. I dont know how that will effect the in flight CG. I thought there was a way to do that called a dump tank ???? The instructions in the ARF were very old and not very good. I did check Kangke's web site and there was a newer version with a little more detail posted there, thank God. Any thoughts? Bob?

If it were me, I would go with the Jett. Customer service is also part of picking an engine. You never know what is going on with Rossi from one day to the next

Jett-50 and a 2 oz. header tank / 8 oz. main tank is what I'd do... [link=http://www.rcuniverse.com/forum/m_4468987/anchors_4468987/mpage_1/key_header%252Ctank%252Cplumbing/anchor/tm.htm#4468987]CLICK HERE[/link] for a good thread on header tanks/ uniflow, etc. Dunno if it is exactly what you are looking for but I did a search on here for:"Header tank plumbing" and had a ton of hits.

Although not an engine you currently have, the YS-45 is pumped so you could put the tank anywhere you wanted... Also stronger than the Rossi-45.

With the Jett 50 and a Bubble Jett blader tank I shoud be able to put it anywhere as well. I just dont know what moving the tank back behind the nose gear on an F-20 will do to the flying habbits. I need more fuel as the stock 7.5 oz tank wont last long. Header tank is another good option. Just a question of plumbing.

I have had both the FX and an MVVS (real close to the Rossi) used the stock tank and used lock nuts on the motor with thru bolts. Never had any problems with fuel delivery if you are worried about that. Otherwise I would go for the Jett. You will go faster.
