Ask Kevin at Keleo if he can install the P-51 operational exhaust stacks for you. I have a set and I love them.. It is so cool when the 200TI in my plane starts up the smoke barks out the stacks!!

I downloaded the manual and it says the engine mount was set up for a Saito 1.80 and "If you plan on using another engine, such as the Saito 2.20, you may need to remove the blind nuts and drill new holes in the firewall for your particular engine." I bought the Evo 35GT and I hope I have the skill to install it.

san26141, captain ron said the Evo 35GT is way too big. You may want to measure.

Here's what I found on my new P-51:

The spinner has a 1/2" lip that sticks back towards the fuselage.

The manual says to place the engine prop drive washer 1/8" ahead of the fuselage. That will not work.

You will have to fabricate a pair of 1/2" plywood spacers between the mount and the firewall.

This is in addition to the spacers already in the kit.

Now the spinner will clear.

Here's mine with the engine running last weekend. 15 pounds 4 ounces dry, ready to fly.

Spektrum DX7, 2 batteries (one on receiver, one on just retract servos)

All I need now is a remote glow lighter, a pilot and some recent vintage glow fuel!

Unfortunately I do not have the plane yet...its gonna be a b-day present in Feb. I was looking at the specs on the Saito-220 and the Evo 35GT and the Evo is 9mm wider on the engine mounting flanges (outside-outside dimension) and shorter in height from top of cylinder to center of crankshaft by about 12mm. (Evo did not supply dimensions from crankshaft to bottom of crankcase.)

Does anyone have the spec.'s on the max. width and height of the firewall?

I hope that the extra ~1cm width doesn't cause mounting problems.

Thanks

Pettit, Good looking model you have there, what engine are you using? keep us posted on the first flight results. On another note, I noticed the interesting styro stand you use to support your model - what make is it and where did you get it?

John.

I downloaded the manual and it says the engine mount was set up for a Saito 1.80 and "If you plan on using another engine, such as the Saito 2.20, you may need to remove the blind nuts and drill new holes in the firewall for your particular engine." I bought the Evo 35GT and I hope I have the skill to install it.


The Saito 220 fits as expected, with just the valve covers protruding outside of the cowl, as the Saito 100 does with the smaller H9 60 P-51.

I moved both the port side t-nuts, increasing the spacing to the starboard side t-nuts by ~3/16". Crank still comes out centered (to the 1/16" .

Without the supplied spacers, and with the 220 slid all the way forward on the mount, the prop disk only protruded about 3/32" past the front of the cowl, a bit too close. So, I still used the supplied spacers between the engine mount and the firewall, and slid the engine placement back on the mount's open rails until I achieved the recommended spacing.

After careful examination of the supplied 5" spinner, I decided to dedicate that as the "static display" spinner, with the four scale blades, and will use a Dave Brown or Tru Turn 5" parabolic, finished with self-etching primer and matching yellow paint, for actual flight.

Included a few photos below...

Rip n Bank -

Thanks for the pic's. I don't understand why H9 would recommend the Evo 35 if it will not fit. Will have to return it and go with the 220.

Thanks
san

OK I think I've decided. Going to go with the fuji BT 32EI on mine. W/modified rubber mounts, it should come out length-wise real close to perfect. The only hitch I have is the mounts that the Fuji comes with are too wide to fit inside of the built up part of the fixed cowl. Does anyone have any bright ideas or experience on how to get past this. I know I can't see the forest for the trees, so lend me your chain saw. I'm planning on reinforcing and glassing the firewall but I don't want to cut much of the wood away. Help!

I got a PM from Capt Ron saying th G35 will fit with a little firewall cutting. Hopefully he'll post some pictures soon.

Spit:

The stand is the one that comes with the new Top Flite Cessna 310

I'm using a Saito 220 and the supplied spinner. I was thinking of getting a Tru-Turn, but I really have to use what's in the kit for an honest review.
