Well I had my first oops yesterday. The cause I am a rookie and the battery fell out of my heli, yes out of my heli and on to the ground while hovering. I just knew it was over when I saw my caliber crap a RX battery pack at 5 feet Well damage to heli wasnt bad about 30 bucks. The bad thing is appartently when the blades broke when hitting the ground, it took the load off the motor, and it kept spinning up till it broke the rod. Can this be prevented, or do you just pray?

Thanks guys wish I was taping it was funny.

We usually try to secure everything under the canopy with some sort of strapping device. I usually use velcro straps to secure the battery, receiver, gyro amp, etc. Wrap each of the devices with a piece of foam, then strap everything down to the battery tray. Glad to hear no one got hurt and you only had minimal damage.

Take Care,
Cheers, Patrick

Praying is OK, but putting a couple rubber bands around the battery works too. Sometimes the engine does spin up real fast and either burns out the cutch or self destructs (as in your case). Fortunately this is rare compared to all the stuff that normally breaks.

In your case there was nothing you could do...as the Battery fell out you could have hit eng cut/T-hold a million times and nothin would have happened....for future reference I tie a loop of fishing line around my female/male connections....all of em....usually tho you dont trash an engine in a crash..... rebuild a do it again....just differently next time!

almost eveytime I crashes the engine keep on going so I have to chance the clutch and the bell. I am yust using dobble side tape to secure the battery, reciver and gyro. Secure the battery plug that connects into the batteryswitch plug. Once when I yust have started up and I was getting the head speed up, suddently the heli yust went back to idle and nothing worked, then I saw the battery plug had felt of! I was so lucky that I haven't got it up in hover yet.

thanks guys, I had it velcroed in but apparently not tight enough. Should I rebuild the os 32 sx ringed or get another? If another which engine? I would need a piston, ring, and connecting rod evrything else seems okay.

Thanks guys

lock at ebay for parts. Or you will find a cheap new engine there.

I blew a rod in one of my OS 32SX-H -- not because of a crash, however, it just blew as I landed and was shutting down the engine. BIg metallic clank, and that was all she wrote.

The engine was under warranty, sent it to Hobby Services, they replaced the rod, piston and sleeve, all for free, and I had it back within the week.

A piston and sleeve will run you $60, a wrist pin another $6.50, and a con rod another $14. (Prices from Tower Hobbies).

You'd be up to over $80 to rebuild it. That's 2/3 of the way to a new 32 Sx-H. Unless you can get Hobby Services to do it under warranty, you're probably ahead in the long run to just get another 32. At least you'll have a spare head, crankshaft, crankcase, backplate and carb.

Sounds good but mine is the ringed version so its more expensive than non ringed

Well one thing is for sure.. Its cheaper then in real engines, I had to pay $1200 when I ran without oil in my snowmobile.

If you wanted to prevent that from happening in case of another battery/ switch failure, you could use a spring just strong enough to close the throttle with power off. The servo will be in a constant strain causing a little more drain on the battery though.

My two cents...

First off, make sure you really have your battery tied down good. I use double sided tape, tie wraps and velcro. Yes, I lost a battery in flight one before... Has never happened again.

Next, use NON-WAXED dental floss to tie the male and female battery connector together. Make a tight knot, and then put a really small drop of fast CA glue on the knot. Your battery will never come unplugged again.

Consider using two seperate battery packs (and two on/off switches).

Fly a heli such as the Hirobo Sceadu that has a built-in battery box. -Steve

Welcome to the world of model helis! Dude, no insult here, or bogus replies. Thats just the way it goes sometimes. Im quite confidant you will NEVER make that mistake again. All of us here have made mistakes, some worse than others. Fix that bad boy, and get back up in the air!
