150クラス×2のタイガーキャットに搭載予定だったが飛行場もなくなり断念、、、未使用の UMSエボリューションエンジン 7気筒35CC世界最小マルチシリンダー星形7気筒、グローエンジンです。 
サイズ感:
円形の部分が外周で約28cm
排気量:33CC
工程:4サイクル
燃料:グロー燃料と、燃料用アルコールを混合した燃料(自分で作る)
出力:多分2hp前後
グロープラグ:4サイクル用 7本(付属)
対象となる機体は、120ー150クラス(20CC~)の丸い胴体の機体です。 当該エンジンは日本でも売られてはいましたので実績はありますが、もう完売した、未使用のほんとうに希少なエンジンとなります。 
 エンジン自体、鑑賞してもよし、回しても音よし、飛ばしても極めて実機感あり、非常によいものですので是非お試しください。 ご質問などありましたら、お気軽にどうぞよろしくお願いいたします。

商品は新品未使用ですが出荷時に工場でテスト始動しています。そのため長期保管で残燃料が乾燥し付着したオイル成分が固くなっています。固着はしておりませんがドライブシャフトの回転も固いです。
これがクタクタになるまで始動は禁止(硬いまま無理に高速回転するとコンロッドが、破断、ピストンを突き抜けたりします)。
当方の同じエンジンでやっていた方法は、
1.プラグをすべて取り外す(あまりに固い場合は、プッシュロッドも取り外す:ドライブギアボックス側のピンをなくさないように!)
2.ペラを取り付ける(冬など寒いときは本体正面を太陽に一時間ほどさらす:暖かくする:ドライブギアボックス内部の専用グリスが固い)
3.グロー燃料(もしくはグロー専用アフターランオイル)を7個のプラグ穴から数滴ずつ垂らす
4.キャブレターからもグロー燃料(オイル)を入れる
5.ゆっくり少しずつ(10度ずつ)ペラを回す、なかなか緩くならない場合プッシュロッドピン穴からオイル(グロー専用でなくても良いらしい)を垂らす(しかしこの部位は決して燃料入れない)
6.少し緩くなったら、大きく左右に360度手で回す
7.数十分ほど頑張って繰り返したら相当クタクタになるはず、スタータでインターバルに軽く回す
8.本体がクタクタになったら、次はプッシュロッドなどすべて取り付け、タペット付近の動きを手動で確かめる
(きつい場合はその周りにも少しオイルを垂らす(決して多くつけすぎないように、始動後、残オイルが焼けて変色する)
9.プラグ以外を正しく取り付けて再度スターターなどを使って(手動が本当は良いかも)数分間、インターバルで回す
10完ぺきにすべてがゆるゆるクタクタになったらすプラグを取り付けて今度は手で左へ回す(ピストンの圧縮(小さい)が規則的にあることを確認して終了
更に備考:タペットは0.1mm。燃料は7%オイル(グロー燃料を、燃料用98%アルコールで割って作る

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
