Thanks Jon for the quick response. Ok for the FT. I would like to get on the waiting list for the FT. I am already on the list for the 310 which is for my Platt FW-190. I will send an email with my info. Also need to update my info on the 310 waiting list.

Hello Jon, Hope all is well. I just got my hands on a GTM 1/4 scale D8 kit. The recommended engine is the 200V, which is shown on the plans. Assumng the 200V is still a good choice for this kit, I was wondering if the FT-200 would be a better option? Looks like the FT-200 would fit inside the cowl and the cylinder heads would be closer to the center line of the prop shaft. In either case a Laser is in the future for this kit. thanks in advance for your time, Bill

Happy New Year. Good to hear things are moving along. Don't lose them fingers! Very hard to build and test engines without them.

Congrats on 40 years and hopefully many more successful ones. As for a special anniversary engine, I guess that is fine. Although I don't think I would buy one. My only question is what would a person do with it? If you are going to sit and look at it, it seems like a waste of money. If you are going to fly it, you mind as well not bother spending the extra money as it may be enclosed in a cowl, and no one will know the difference but you. Plus, a bad day at the field and that special engine may up being junk. When the day comes to hang up the hobby and you are still here you may not get back what you bought it for. If you are no longer here, you wouldn't care what it goes for as you won't be around. Anyway, congrats again.

Oops, sorry, my bad. In the future I will make sure I am in the right thread. Thanks for the update.

Hello Jon, Any updates on when the FT-310's will be ready? thanks, Bill

Thanks Jon. Will do as it sounds like the FT310 is the way to go. Just modifying the FW and not have to worry about the fuel tank positioning sounds like a plan. As for fuel distribution in radials, the Saito's have single carbs, were known for flooding out the bottom cylinders. In my case on my 170R3, #2 and #3. Saito came up with this W design (picture 1) to try and even it out and stop the flooding. However, this modification caused the #1 cylinder to run leaner and hotter than #2 and #3. The temperature difference between #1 was anywhere from 10 to 20 degrees cooler than #2 or #3. Midrange transition was often sluggish and hard to tune. A gentleman from the UK, a retired engine designer for Marlin Lindy Cars, Ray English designed a mod (picture #2) that fed all the cylinders evenly as well as keeping the cylinder temperatures within a few degrees of each other and eliminated the transition issues. I had this mod done by Ray to my 170R3 and she runs like a champ, idles very well and transitions with no sluggishness at all. I am running my radial on nitro, too. Saito has been using Ray's modification in their radials. Edit: Looks like Morris Mini Motors carries this mod for the Saito Radials https://www.morrisminimotors.com/saito-fa-170-r3-glow-3-cylinder-radial-4-stroke-engine-intake-manifold-modification-conversion-kit.html

I don't think so. Most likely at me and my post above. I was thinking an inline would be easier to mount in the FW-190 since it has hard rails for the engine mount. That way I would not have to do any firewall or fuel tank modifications. I have a Saito 170R3 radial but it isn't enough to power for the Platt FW-190. I will check Nick's thread out on the Seafury as it maybe something I can do with not a lot of work

I am going to be building a Dave Platt FW-190A in the near future. The plans call for a Super Tigre ST2500. Talking with Jon the FT310 would be a good engine for that plane. But if an inline 310 would fit I would be interested in that. The plans show from the engine mounting beam to the top of the cowl is 4.71 inches / 119.63mm. The cowl is split with the top half being fiberglass and bottom half is built up. But I do have a Don Lein/Bob Holman full cowl that will fit it. The total height of the cowl is 10.44 inches / 265.18mm. The firewall to the front of the cowl is 9.48 inches / 240.79mm. If the inline 310 would fit, I would be interested in that, otherwise it is the FT310. So, both would be my vote. Inch measurement in attached image are in blue. MM numbers in my post are calculator conversion estimated.

I would prefer a modified dumpy type with the option to purchase an upgrade if needed. I don't know what the noise limits are there but ours over here recommend 96 decibels measured at 3 meters (20 feet). Although, each club is allowed to set their own limits as long as it doesn't violate local town laws. One club I belong to follows the 96 decibels measured at 3 meters as there is a housing development nearby. While the other club is at a local airport, and we do not have a set rule on noise since full scale fly there too.

Looks and sounds great!!!! Happy Holidays to all.

Only listened to it when it was running and sounding so sweet.....

Definitely useful. Saved for future reference. Never thought about listening to why it doesn't start. It was always looking at what it was going on with it.

Some people learn by listening Some learn by watching others Then there is always those that need to pee on an electric fence to find out for themselves

Awesome!!! I would be interested in a 200.
