Davids rc sounds like you are well on your way. There are a lot of skilled airboat builders on this forum that can help you. Do you have pics so we can see what you are working with? You should meet up with DJLaPalme, he lives in your area.

this is the only pic i have

RE: airboat in progress
if u only have 1.2 hp u have to much prop on there. slick bottom would help u run the hill better. but u have to get some more rpm . maybe bigger carb would help too. i have a 4.25 27cc motor and i run a 14x7 3 blade. my 50cc twin with 5 hp i run the 16x10
|
RE: airboat in progress
so a 13x8 3 blade would be better
|
RE: airboat in progress
yes i would think. how much does your hull weigh?
|
RE: airboat in progress
bout 5 or 6 pounds this is my first airboat
|
RE: airboat in progress
i had a friend cover it in epoxy feed carbon fiber and i think it may be to heavy
|
RE: airboat in progress
it should move on the grass. my boat weighs 29.40 lbs. if you motor is 5 lbs and hull is 5 lbs . it should move. post a better pic when u get a chance. is the boat a flat bottom?
|
RE: airboat in progress
yes it is a flat bottom
|
RE: airboat in progress
i would try other prop. and go from there. if all else fails u can buy a 27cc 3.25 hp cy motor off ebay for 150. that will make that thing fly
|
RE: airboat in progress
i was told that i could cut this prop down if need be is that true

RE: airboat in progress
You can, but you have to balance it or it will vibrate and wear out your bearings and loosen up your bolts and screws. Dennis

RE: airboat in progress
ok well i think im just going to build a new hull and buy a new prop the problem is their is not many pushers to choose from especially in the 3 blade where can i obtain planes for the hull or is it better to just wing it
|
RE: airboat in progress
If you cut the prop down go no further than 1/2" on each blade from the tip.
|
RE: airboat in progress
i have a cut down reshaped and rebalanced 16x10 to a 14x10. if u want to try it,. before i would build a new hull i would get a different engine. thats not alot of power for a heavy motor
|
RE: airboat in progress
that would be great if you do not mind ptr34 how can i get it
|
RE: airboat in progress
maybe coming up that way on the 5 i could bring it and we could me at the pond
|
RE: airboat in progress
