I have been looking at the TF and H9 P-47 ARF planes for a while and finally decided to get the TF due to the great deal at Tower ($369-$40 off-$50 member discount=$279 shipped) making it the same price as the H9. I need your advise on a powerplant from the following:

NIB Magnum XL 91 FS
OS 120FS (from 90's)
FTL26 26cc gas engine from HK (it will be my 1st gas engine and I would have to buy it @$129)

Thanks

OS 120 is too heavy.
I do not know the other two engines.
I'm flying for two years now, and it is fabulous.
Initially had mounted an OS 110, flight hour with a SAITO 125 ​​which has the same size as an OS 91/110.
The sound is fabulous!!

If you already own the .91 and 1.20 four strokes I would use the one that balances best. I own a Magnum .91 and it is a good engine but if the plane can be made to balance with the 1.20 without adding more tail weight, I would be inclined to go with the 1.20. Either of the four strokes will sound way better than the two stroke gasser and that would be important to me for that type of plane.

I will stick with either 4 stroke

Thanks

Go gas! No mess to clean up and still sounds good. I havethe DLE20 in all my TF warbirds P-40, P-47 and P-51, and they fly 15 min on 10oz of gas. But if you must go glow I would opt for more power and use the 1.20

Gasser .......... OS GT 22

Saito 115 not too heavy and will haul the mail in 60 size TF Warbird

My budget only allows me to use what I have (the OS120 or Magnum 91fs). For what I have read, if I use the 91 I would have to add a few ounces on the nose, so I am inclined to use the 1.20
On the review done here at RCU, a OS 91 was used but they added somewhere around 4 to 7oz of lead to the nose (the 1.20 is 8 oz heavier than the 91).
Anyone that owns this plane with either engine please advise on balancing tips (especially where weight has to be added with your current four stroke)

Thank you all for your advise.
Best regards
